Introduction How to Fix a TV That Won't Turn OnModern flat screen TV's have a known problem with capacitors going bad. If your LCD or LED TV won't turn on, or makes repeated clicking sounds, there is a very good chance that you can save hundreds of dollars doing this simple repair know, I know. You're thinking, "Tinker inside my LCD HDTV. Are you crazy?" No, I'm not crazy. This is a repair almost anyone can do and this fix will work for any 1 You sit down and get comfortable, ready to watch your favorite TV show or movie. You turn on your TV and...nothing! Unsure if you hit the power button, you try again...again, nothing! But you do notice a clicking sound emanating from your TV. "What the heck? No...Oh, crap!" HDTV's aren't cheap. Most of us have to save, or at least be prepared to spend $800-$1000 on new one. Heck, I'm sure many of you don't savor the idea of spending a few hundred on repairs. I have good news. This repair is actually quite simple, and with only a few basic tools and about 20 bucks, you can have your TV working in less than an step-by-step repair below was done on my Samsung LN46A550 46" LCD HDTV, but this is an easy repair on any bad News. If your TV is physically damaged in any way, been dropped, has a broken screen or gotten wet then this repair isn't for you. But if your TV was working one day but not the next, read 2 Tools NeededYou will need 5 basic items below for this repairSoldering Iron & solder Phillips Screwdriver Pliers Wire Cutters Replacement Capacitors from AmazonIf you need a soldering iron, that no problem. They are cheap and easy to use. I highly recommend this 60 Watts Soldering Iron Kit. It's less than 20 bucks. If your looking for the lowest price possible, this 60W soldering iron with stand is about $8 shipped prime and will work fine. Step 3 Optional ToolsThese tools aren't required, but they can make the process easier. Magnetic, ratcheting, flexible screwdriver to help remove all the casing screws Cordless Screwdriver to help remove all the casing screws Desoldering wick absorbs melted solder Solder sucker remove melted solder Flux Pen flux on solder makes it flow and less "sticky" Multi-Meter test for bad Caps, helpful if there are no visual cluesStep 4 Remove Stand and Wall MountAfter unplugging everything on the TV, you will need to remove the stand. If your TV was wall mounted you will need to remove the TV from the wall, and remove the mounting bracket from the back of the arrows Remove these screws to remove stand from arrows Remove these 4 screws to remove a wall mount not shown from your TV sits on top and inside the stand, so it wont just flop over when you remove the stand screws, but it's always safer to have a friend hold the TV upright as you remove the screws from the stand. Then each of you grab a side and carefully lay it flat on a carpeted 5 WarningWhen handling your TV always keep it straight up like your watching it or laid flat. Any force applied at odd angles can damage the fragile glass 6 Remove All Screws That Attached the Back Casing of the TVAbove is a a picture of the back side of a typical TV. The left picture is my LG 42LN5300 and the right picture is my Samsung LN46A550, but all TVs are similar. Remove all of the screws along the outer edge of the back casing. There can be anywhere from 10 - 16 of these will also be screws within any area where the are power or cord plugins. You can see these in the lower middle of the pictures. highlighted with the red rectangle on my SamsungStep 7 Don't Forget the Hard to Find ScrewsOften in the area where you plug in cords a screw or two can be found. remove these as 8 TV With Back Casing RemovedWith the back casing of your TV removed take a picture of your TV. This will help during identify the "power board". Every TV is a little different, but the power board will have can shaped capacitors and is the board that the main power from the plug goes to first. On this Samsung TV I put a green rectangle around the power board that we will be working on..Note The other "green" board is the "logic board", this is the computer that runs the TV. Repair of the board is beyond the scope of this article. But it's most likely not the problemStep 9 Remove Wiring Harnesses From Circuit BoardRemove all of the wiring harnesses from the circuit board. A simple tug on the connector clip not the wiring should be sufficient to remove them. On this particular Samsung board there are 7 different 10 Remove Screws Holding Down Circuit BoardRemove the screws holding the power board to the TV chassis. Most boards will have 6 screws holding them down, as does the one shown in the picture. But look it over there could be more or is a power supply board and not particularly sensitive, but it is always a good habit to handle these boards carefully and by the 11 Identifying Bad CapacitorsThis TV repair focuses on the small "can shaped" Aluminum ElectrolyticCapacitors. These capacitors come in many colors and sizes but are easy to find on any power board. Not only are these the most likely cause of your problem, but bad ones are simple to find and simple to replace. In most instances you will be able to visually identify the bad capacitors. You don't need any special skills in electronics or 12 Visible Failure 1 - ​Bulging VentsWhen a Capacitor fails, the chemical reaction inside the capacitor can produce hydrogen gas, so capacitors have vents cut into the tops of their aluminum cans. These are intended to break and release the gas that has built up inside the capacitor. So, a capacitor which has failed can show bulging at the top..Step 13 Visible Failure 2 - LeakingAnother sign of a failed capacitor is leaking fluid electrolyte. This can be an orange or brownish discharge from either the top or bottom of the capacitor. Usually, with leaking the capacitor will also be bulging. But a capacitor can bulge but not do not always show visible signs of failure. But, if you see either of the 2 signs above on your board, you can be confident that you're close to fixing your TV. If you don't see these signs of failure, but your TV had the tell-tail clicking sound, you still can be fairly certain the steps below will fix your 14 Find the Bad Capacitors on Your BoardOn power board pictured above, I have indicated which capacitors you should be examining for signs of failure. These Capacitors are Aluminum Electrolytic Capacitors, and are the most likely cause of your problem. The capacitors with the green arrows are the most likely candidates for being bad, but the blue arrow are other capacitors to worry if your board looks a little different. Simply examine all of the capacitors and usually the faulty ones stand Do not bother with the large capacitors 2 or 3 will be on every board. These are high voltage, rarely fail and for safety require a little more expertise to work board probably looks different, that's OK, just examine any and all capacitors on your board that look similar to ones pointed out The pictures above are actual closeups of my TV's board. Notice how the blue capacitors in the foreground are bulging. These are the capacitors I will replace. All other capacitors look OK. If you can find replacements for all 4 of these capacitors, and any others that show visual signs of going bad, I recommend replacing them all while your in here..Step 15 Removing the CapacitorsCapacitors have polarity. What this means is, like a battery, they have a positive + and a negative - side. Before removing any capacitor, note which side the white stripe of the capacitor is facing. You will need to put in the new capacitor in the same direction. You probably noted on my pictures that I actually made a note on the aluminum heat sink with a 16 Let the Iron Do the Work. If the Capacitor Does Not Easily Pull Out, Do Not Force that you've identified the capacitors that look bad, turn the board over and carefully identify exactly which points on the board are the wire leads from the these them with a "sharpie" type pen to keep track. Grab your friend and have them help you on this next step. Balancing the circuit board on its side while using a hot soldering iron and pliers can be a bit tricky. Plug in the soldering iron and give it 10 minutes to get hot. With the circuit board on its edge, have your friend grab one of the capacitors with the pliers and apply a very gentle pulling pressure. Apply the tip of the soldering iron to one lead on the back side of the board and hold it there until you see the solder melt. Now switch to the other lead until it melts. Keep going back and forth on the leads. Each time the solder will melt faster. After going back and forth a couple times the capacitor will easily come out. Repeat for each capacitor that you are replacingStep 17 Time to Go ShoppingCapacitors are rated for their application and you must replace like for like. There are 3 ratings to identifyuF micro farads Temperature VoltageuF micro faradsIdeally you should match the uF and the temperature rating exactly. But it is acceptable to use a capacitor rated higher uF if it is within 20% of the Try to match the temperature rating, you can go higher, but not if Possible. You can use a larger value if needed. Not you can find replacements capacitors at your local electronic store. But it may be easier to buy replacements from my repair I needed;1000uf 10v Capacitor 105c High Temp, Radial Leads820uf 25v Capacitor 105c High Temp, Radial 18 Install New CapacitorInsert capacitor, making sure to place the negative side in the correct location.

If there is any flux or solder residue, simply clean the area with a damp 23 Reverse the ProcessAttached the circuit board with the six screws. Reattach all seven wiring harnesses. Replace the back cover. Turn on TV and be happy that you save yourself a ton of fix works and it worked for me. Cara Memperbaiki Tv Tabung Samsung Lampu Indikator Hijau Tidak Menyala Saat Standby Samsung chasis KS1A TDA9381 stand-by tidak kerja KASUS Samsung chasis KS1A dengan TDA9381 Mikrokontrol tidak kerja. Lampu led hijau tidak mau menyala ketika stand-by. PEMERIKSAAN dan ANALISA Seperti biasanya pada teve merk lainnya yang juga menggunakan TDA9381, maka jika bagian mikrokontrol tidak kerja, maka selalu kami cek Pertama cek tegangan Vcc pada pin-54/56/60, dan semuanya OK Cek tegangan pada osilator sistim pin-58/59, dan semuanya OK ada tegangan sekitar Dipastikan diperiksa dengan osiloskop juga jelas nampak sudah ada pulsa-pulsa. Cek tegangan RESET pada pin-60 juga ada sekitar 2v Cek tegangan pada pin-2/3 SDA/SCL TDAS9381 maupun ic eeprom juga ada sekitar 5v. Maka analisa kami ic TDA rusak pada bagian mikrokontrolnya. Setelah diganti....ternyata problem sami-mawon...pada wae....alias tetap sama saja.... Wah....harus perlu banyak mikir........ini...........!!!! PEMERIKSAAN dan ANALISA Dari hasil Pemeriksaan dan Analisa sepertinya syarat-syarat agar mikrokontrol mau bekerja nampaknya sudah terpenuhi semua. Setelah berpikir agak lama….maka yang masih kami ragukan adalah; “apakah tegangan RESET betul-betul sudah bekerja?” Untuk itu kami buka-2 semua koleksi skematik chasis KS1A yang kami miliki. Ternyata sirkit RESET SAMSUNG berbeda dengan teve merk lainnya yang menggunakan TDA9381. Dan disini kami ketemukan 2 macam versi dengan sirkit yang sedikit berbeda. Kasus yang sedang kami tangani menggunakan sirkit reset * Dari skematik nampak jelas bahwa tegangan RESET diberikan oleh ic KA7632 pi-6....terus lewat transistor Q902 Langsung saja kami cek tegangan pada pin-6 tersebut. Dan ternyata tegangan tidak ada sama sekali.........dan diketemukan penyebabnya zener DZ810 pada pin tersebut short Setelah zener kami ganti..…..pin-6 ada tegangan 5v......dan hasilnya langsung ........jooooos.... very-very OK * Sirkit reset gambar dibawah. Tegangan reset diberikan ke pin-60 dan pin-64 Sirkit reset gambar dibawah. Tegangan reset hanya diberikan ke pin-60. Dan pin-64 ada tegangan fixed sekitar 2v CARA MEMERIKA TEGANGAN RESET YANG BENAR Lepas colokan listrik. Pasang volt-meter pada kolektor transistor Q902. Ketika colokan listrik dipasang kembali, maka kolektor sesaat harus ada tegangan kecil dan kemudian kembali nol. sumber Artikel Lainnya Cara Memperbaiki Tv Tabung Samsung Mati Protek Beberapa Kerusakan Tv LCD Samsung dan Solusinya Sirkit Protek Tv Tabung Samsung Cara Memperbaiki Tv Tabung Samsung Gambar Ada Tapi Suara Tidak Ada Cara Memperbaiki Tv Tabung Samsung Transistor Horisontal Rusak Terus Cara Memperbaiki Tv Tabung Samsung Gambar Bergaris-garis dan Melengkung Cara Memperbaiki Tv Tabung Samsung Gambar Separuh Layar Cara Memperbaiki Tv Tabung Samsung Gambar Gelap Cara Memperbaiki Tv Tabung Samsung Lampu Indikator Kedip-kedip Cara Masuk Service Mode Tv Tabung Samsung Postingan populer dari blog ini 1.

Ya udah akhirnya sibuk nyari kodenya ke blog rekan-rekan yang udah pernah posting tentang service mode tv, saya coba semua tapi tv nggak respon sama sekali, ya ampun kok gak ada yang cocok semua,waduh waduh waduh. Akhirnya hanya satu AJI-AJI yang belum keluarkan yaitu AJI NGAWUR namanya he he he... Pada tv SAMSUNG untuk masuk ke service mode biasanya ada 4 langkah tombol yang harus ditekan, akhirnya saya pencetin 4 tombol yang di akhiri dengan tombol POWER, dan ketika saya pencet tombol lalu tombol HELP kemudian tombol SLEEP dan terakhir tombol POWER, eeehhh.... nongol deh tuh service menu. 1. SAMSUNG SLIM FIT TV Gambar Separoh Layar Sore tadi dapet panggilan servis tv di desa Bogorejo dengan tv Samsung jenis Slim Fit DNIeJr type CS-21A630BL,tv ini menggunakan IC single dengan seri TDA12156PS/N3/3 dan IC vertikal LA78141 dengan kerusakan gambar hanya tertampil separoh saja,bagian tengah ke atas blank hitam,sedangkan bagian tengah ke bawah normal dengan bagian tengah terlipat gambarnya. Bila di amati kasus kerusakan ini mirip dengan kasus tv Polytron kemarin,hanya saja pada Polytron di sertai dengan garis-garis,tetapi sumber kerusakan adalah sama yaitu diode yang menghubungkan antara pin Vcc IC vertikal dengan pin OUTPUT STAGE Vcc atau tepatnya adalah D303=IN4004,setelah penggantian diode tersebut barulah gambar tv bisa normal kembali,walaupun kenyataanya bila di tester diode tersebut tidak menunjukan short circuit maupun mati,tapi bila di aliri tegangan barulah kelihatan errornya. OKE teman-t Tips SAMSUNG SLIM 21' transistor horisontal panas Revisi 01 - September 2010 Seorang teman teknisi minta tolong dengan Samsung slim 21” UOC TDA12156 - transistor HOT TT2222. Info pesawat tersebut belum ada setahun sudah 4 kali rusak transistor HOT-nya. Ketika kami ganti HOT dan coba dihidupkan, ternyata belum satu menit HOT sudah sangat panas sekali. Dugaan kami problem karena HOT under drive. Kemudian HOT kami lepas lagi dan mulai melakukan beberapa langkah pemeriksaan Ukur tegangan B+, hasil normal sekitar 125V Ukur tegangan suply horisontal-driver sekitar 8v, ini tanda tanya ? Ukur elko pada horisontal driver dengan ESR-meter, hasil masih bagus. Kecurigaan kami jatuh pada problem disebabkan tegangan horisontal driver kurang sehingga menyebabkan under-drive. Kami lacak sumber tegangan suply yang berasal dari sekunder tranfo switching. Setelah kami ubek-ubek hasilnya tidak menjumpai adanya kerusakan part. Kemudian sirkit kami pelajari dengan lebih seksama maklu
