No troubleshooting needed for this issue. Check the tv's warranty then call the manufacturer to get this tv replaced or fix. If tv's out of warranty you still need to call the manufacturer to ask where is the closest Service center that can fix your tv.

No tv picture but sound poloroid 50gsr3000


Back-light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

Screen went black smoke coming from back tv is 2007 according to back sticker still have sound


Smoke = overheating = big short = big failure of a part.
Unplug the tv immediately - you don't want t set your house on fire - and call a repaiman. Since the tv has been smoking then the damage will be extensive - a lot of parts, even entire boards, have been damaged. Te repair will be costly.

Hi,
Most probably, Electrolytic condenser in the Power supply to display circuit may have punctured resulting in smoke coming out. Take tv to service centre. There is no other option.
Good luck.
Rating the solution is highly appreciated.

Poloroid 32" flat screen


Yep! If under the 1 year warranty get it in right away. If out of warranty then it's possibly a power supply issue. Probably a $100 to 200 dollar repair.

TV screen wont turn on but just a loud noise coming from the tv


I think maybe the G-board needs to be replaced. A TV shop will have to repair it. They normally start around $200.00
