I came home one day and turned the TV on and it had nothing, no picture and no sound. This is the first time that this has happened to this TV which is almost 7 years old BUT it did have the blinking red light issue which I fixed by unplugging the TV for awhile, the problem would come back every now and again and when it did I would do the same thing unplug it and wait then plug it back in.
I took the TV apart hoping it would be something as simple as a fuse, I only found 1 fuse and it was located by the power cord it looked good, and since I am getting power I figured that couldn't be the problem. My knowledge of electronics is VERY limited and as of right now so is the repair budget so any help would be greatly appreciated.
If you have the ability to remove some of the
connectors to the main chassis & flip it over
so you can see the chassis from the bottom,
inspect the solder connections around the
power supply and near the high voltage..the
flyback area, you could have a cold , cracked solder joint or several of them due to age of the tv. Use a magnifer & bright light to try
& spot them, resolder & put the chassis back
together, see if this helped.

Hello! Does sound comes out of TV speakers? Or you have "home theater" hooked up to? In first occasion: TV turns on, stays on, display blinks once, then nothing? Inverter is at fault. Second occasion: TV turns on, stays on, display glows dark, sound OK, no picture: T-con board at fault. Third occasion: TV turns on, shuts off, sound is coming through "home theater"-OK. Power supply or inverter, or T-con are at fault. TV need major diagnostics and repair in every case. Let me know if you can handle that. Will guide you through the process. Thanks, Alex.
a panasonic tv will shut down after a short time with no video input. it sounds like the setup menu in the receiver has defaulted and needs to be setup again to coordinate the audio and video signals. ive seen many yamaha menus default. dont let geeks in your house.
