I have a Visio VO42L10A and When powered off the Visio symbol is orange. When I turn it on the light just goes off but the TV comes on. Not long ago I lost sound but turned the set off and back on again and the sound returned. It has done this a couple of times. Recently the TV turned off suddenly and it would not turn back on. The orange light was on and when I hit the power button it went out (AS USUAL) but there wasn't a backlight sound or picture. I left it unplugged for an hour or so then plugged it back in with the same results. I left it turned on and went to do some research on the problem. well a Half hour or so went buy and I heard a slight "POP" and the TV was on but no sound. So I turned the set off and back on again and there was sound. I am guessing that it could be a solder joint. The set has been performing just fine again for the last 2 hours, but I'm sure that there will be another incident. Any body have any Ideas where to start?
No Backlight, Picture or sound...sometimes

by MgiffuneI have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.
I ordered a supposedly ‘new' Tcon board this time, and... -
by IerwinHello everyone,
Ive got a UE60KU6079 on the workbench that is giving me some headaches trying to troubleshoot.
The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
Anyway I still fully expect that there has been something seriously damaged... -
so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!!
what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol!
i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing...-

by DodgethisHello all,
This is my first post, but long term lurker on the form learning as much as possible about these TV's. I was given this TV as due to a power outage of constant On/off of power to TV. The TV originally would just click on and off (Typical Reboot Cycle). I opened the back of the TV, and troubleshooted by taking the 96 pin LVDS off one at a time to see if I had a picture on either side. I finally fixed the reboot cycle by finding the error on the left side of the screen off connector CN 1301, and the TV would stay on. Further troubleshooting led me to the driver boards where...5 Photos - Loading...
