Question about Samsung Televison & Video

1 Answer

The tv screen goes blank then flickers then looses its channels, this continues for about an hour then everything seems normal. Could this be a dry solder joint, as once the tv is nice and warm the problem stops? If this is the case, what is the most common component to do this and is worth my while fixing it or resign the set to the loft?

I would check the power supply board for dry joints and bulging capacitors (capacitors with domed tops).

I have a RCA L32HD31YX12 TV. The TV works fine for a half hour and then the screen flickers and goes black. The sound continues. If I turn the set off for a half hour, it works again for another half


You have answered your own question, someone needs to open it and find a loose plug or broken solder connection--if it reacts to being tapped on that is the issue- a physical problem inside.

We have a similar problem when changing channels/surfing, the TV will begin to power cycle, until you unplug THE CABLE TV input, then it will turn on again and stay on as you rehook the cable and change channels....till it decides to do it again, DTV channels seem to trip it up, but not sure....if I leave it on the same channel it will run for days. Yep and the cable TV is grounded outside

2 problems- 1-gasket is hanging loose on top of protection screen. 2- TV goes blank and I lose the picture and sound only on some channels at 9:00pm every night


unscrew the screws along the sides and top at back. gently lower screen forward and look inside--you should see the gasket--reattach it or remove it...I just removed it after staring at it for a year or more
