Having problems with your Flat Panel Televisions ?

Power light is red so I guess it's getting power but when I try to turn it on nothing happens. I know a green light indicates it is on but that is not happening and I also have no remote.



Answers :

The standby 5vdc power is working , that is why the front LED is on but it may be in the safety shutdown mode due to short circuits or bad 12vdc and 24vdc power supply section, or bad main cntrol baord, shorted circuits in the backlights inverter board. You will need to do in-depth troubleshooting.

All of a sudden the screen went black, but the power indicator light did NOT change to yellow (as it would have if the TV was in the off state). The remote control wouldn't tur
