hi i have condensation in the back of my samsung lcd tv it turns on but it just flickers anyone can help thanks

0ne of 3 has failed:
(in order of probability):

1. Backlight inverter
2. Power Supply
3. Backlight

Please seek the expertise of an experienced TV repair technician - as they contain potentially lethal voltages that must be properly discharged before work can begin.

Thanks!(*&^%

I have samsung lcd tv model LA32B350F1 no power & no standby

you need to hook the cables up to the tv if you want sound to come through the tv.

hey Adam i have a samsung that has been doing that.it would come on then after a few minutes the picture would go ou but the sound still worked.i found that one of the connectors that plugs into the LCD board had a broken solder joint were it connects to the back lighting .just unplug your lcd connections if its bad you'll know it because it will come out.

YOU HAVE TO TURN VOLUME OFF ONTV AND PUT YOUR SURROUND SOUND ON AUX THATS HOW MINE WORKS

optical connection in tv is only input optical connection in receiver is only input will not work.need to connect rca jacks to tv's audio out jacks behind tv to any available input in receiver

hi is the power still coming on? if yes no need for power . have u put anntenal & change the chanels b4 then to see if sound will come .if ye s its yuor backlight inverter u can also disconet ur inverter plug & power on  the tv & change channels if works change ur inverter if dead change your ad or mainboard .
for replacement , lcd parts .com. will help

ok your tv does not come with the very best sound, you have to get a receiver 7.1 or you can use the optical wire , that's if the system you are using has that option.
