Hi, so I was told to replace my psu by a tech because of what the service manual said. I replaced it and its doing the samething. No picture but sound. All of the readings are coming out correct. I tried to do a reset on the logic but but nothing happens. I can do a reset on the main input board but nothing happens after it resets the TV. The fan on the main input board does not come on at all. Please help. I can control channel, source and volume but still no picture.
This no picture but sound issue is not caused due to power supply. The loic control board is also ruled out because all the other functions are operational. That leaves us with two possibilities 1) Sustain board(S) or 2)Buffer BoardsIt is not p ...

Hi, can you help me with this TV please.
Hi, I have a Olevia 232-T11 LCD TV. First my TV wouldn't turn and the blue light just stayed on. I replaced the power supply board and now my TV turns on and the screen lights up but I get no picture or sound. The slave backlight inverter board has a blue light when you turn the TV on but goes away shortly after. The screen stays on but I have no sound or can't control the channel, volume or source button. Please help.
If the tv is not coming on but there is no picture or sound then it is a 100% guarantee that its a problem with the audio/video main board of the tv. I am sure that replacing the same would resolve the problem. Please get me the part number that is p ...

Hi, I bought a Vizio L32 HDTV10A that didn't power-up. There were charred components on the power board (an 8-pin IC with heatsink and 2 resistors). I replaced the power board, and the power LED then turned on (yellow) when power was applied. When the ON button is pressed, the power LED turns green for roughly 8 seconds and then the power LED turns yellow again. Nothing else happens.
I checked many components (fuses, capacitor ESR, diodes, etc) on the main board and the master and slave inver

In the back of the tv we hear it click 3 times then it turns off by itself and it repeats the on/off process but nothing shows on the screen. I ordered and replaced the power supply board and its doing the same thing with the new board. Please help!

Failed Repair Job. A friend of mine called a loocal repair shop to fix their LG50PC3D 9 x 10V 3300uf 105c Capacitors on the Power Board were swollen 1 x 50v 680uf 105c Capacitor on the Power board was swollen. He replaced them with the following. 8 x 16v 3300uf 105c 1 x 25v 3300uf 105c 1 x 50v 1000uf 105c The replacement of the capacitors didn't help and he simply left the tv unrepaired. My question is, can you get away replaced the 10v 3300uf with 25v 3300uf? and the 50v 680uf with a 50v 10
Replacing the 10V caps with 25V caps is perfectly fine. In fact, if it was manufactured like that, those caps may not have blown.Replacing a 680uF with a 1000uF could be problematic depending on it's function.680uF is pretty specific when ...

I have a Samsung LN40A530P1FXZA. It will not power up. I get 2blinks followed by short quick blink and then it repeats itself. I have replaced the power supply board and also the main board, and it still will not work. Does anyone have any idea as to what is going on with this tv? I wish I had an error code book for this tv, but I do not. The only thing I have not replaced is the TCon board. Need someone's help.
Try to download the manual on www.retrevo.com to see the error code for sure..Before you decided to replace t-con board please refer to the manual first,,but there is the possibility that t-con was faulty.Hope it helps..don't forget t ...

The led started flashing steady on-off-on-off. When I first plugged in the led was on solid, now

I need detailed schematics with wire codes and values for diagnosing problems I am having with a Westinghouse SK-26h520s. The original problem was a dead machine, no indicator light so no power, replaced power supply now have indicator light but no sound or backlight, figured bad main board. Replaced board, made no difference. Any information, help or schematics with points and corresponding values to test with a volt ohm meter would be greatly appreciated

Samsung PN50B450B1DXZA will not power up. When I try to power it on, it makes a clicking sound and then nothing for 10-15 seconds and another clicking sound. The Red LED on the front flashes when it clicks but nothing ever appears on the screen. I removed the back of the TV and inspected Capacitors but do not see any that look to be bulging. When I try to power it on with the back off, I see a green light quickly flash on a logic board just below the power supply board. Are these clues helpful

TV has worked just great since purchased in 04. Sat down this morning, grabbed the remote and nothing happened. I replaced the batteries in the remote, tried it again and nothing. I tried the manual power button on the front of the TV and still nothing. I tested the power outlet and it works fine. As I plug the TV in, I hear a soft click as if it is trying to power on but still nothing happens. I pushed the reset and it makes a soft click but still no picture or sound. Could you possibly help
Hi. This is an all too often occurrence. The TV's manufactured in the earlt to mid 1990s relied on an inferior set of capacitors in the power supply and mainboard components. They should have lasted about 25 to 30 years, but most are on ...

Visio VO420E, The left side of screen has a 6 inch wide group of colored lines, I removed the cover and the lines are directly in front of the main circuit board area (not the power supply board). Do I need to replace the whole board or is there a component that is known to cause this? I would appreciate any help you could give me.
Lines like that are almost always a bad LCD Panel, but just to test...Bring up an onscreen display (setup menu, volume bar, etc.) that originates from the TV ITSELF, not your cable, satellite, etc. You need something that intersects the area ...
