Re: sanyo model FV3982 intermittent sound but no picture
ok, I ran TV out of the outside case for hours. It worked fine and never went to a black screen with sound only. Only variable is that the garage is cool, around 50 degrees. I added some ventilation holes with a drill in the back near the boards and put it back together. I now have it playing in the house where it is warmer. So far, so good. Did anyone ever run into this problem? -
Re: sanyo model FV3982 intermittent sound but no picture
in a few threads people have also added pc fans to tvs to keep them cool etc maybe if the set plays up again heat one board at a time with a hair dryer untill the set shuts off then concertrate on that board by heating a smaller area to track the faulty part.Comment

Hi, I have a Samsung UE50TU with:
- sound and backlight, but no picture
- when it arrived, it had a picture for a few seconds
- it keeps rebooting
- without ribbon cable between the two panel boards, it does not reboot but I have no picture
- without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
- when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.

I 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... -
Hi all
I was just given a Samsung TV with the issue. I read various threads and videos and attempted the ribbon tape method to gain an image, but no luck.
Symptom:
No picture no sound.
When I plug in the power cord, Backlight LED turns on for a half second and then turns off. The red LED next to the power button located center bottom flashes 2 or 3 times. When the power button is pressed after, it does the same thing.
No sound at all.
What I tried:
1. I tried unplugging the left or right ribbon... -
Just picked up an iMac powerpc for $1 at auction. changed pram. This is working. Problem, barely any sound. I have everything cranked up in software, reset nvram/pram - nada. I do get sound ONLY if I plug in a powered speakers in headphone port. I do not get the startup bong.
I get almost no sound with normal headphones. I mean, you can barely hear it. Took the board out and by eye found these 2 inductors broken. Not sure if they are for sound. Speaker is also plugged in and I tried a normal pc speaker in its place - still zilch. Are these inductors the culprit?
I cannot find any schematics... -
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...
