TV Repair Help for a TV With a Black No Image on the Screen ...I Have A Sanyo TV I Can Hear But Black Screen Im 14 And Dont Know What To Do ! .... power button the power light goes from red to green, the screen flashes on then goes black ....Troubleshooting LCD Backlight Failure Samsung LNT-4066 ...
One reason may be that you don't have the tv plugged into a surge suppresor. If you don't have one, its advisable to get one, as lcd's/plasmas are quite susceptible to small power spikes.
Try unplugging the tv for one hour, then plug it in and see if the tv corrects its own issues.
If that does not resolve the issue, pay attention to the number of times the power light blinks before shutting off. Thats usually a 'fault code' for troubleshooting a more indepth problem with the machine.
Five blinks is a severe hardware failure supplys not working. Viper is down. You have atleast a bad power supply board could have taken out your sustain boards. If you are good with a meter you can measure voltages and see if just your power supply is dead. If you have never handled a multimeter you will need a tech and a power supply is not cheap..Power supply is about a 600 dollar board.
it could have over heated you can try to reset it first unplug it for about five minutes and try to turn it on if that dont work the remote might have a set button try holding that down until the red light flashes twice, then turn it on if not then hold the power button down on the set for a good five seconds to see if that resets it. if none of that works you will have to go to panasonic .com for the reset instructions.with the red light blinking the power supply is most likely good you just need to reset i.
