I have the same problem. After a power surge, tv wont turn on. It was on a surge protector when it happened. All fuses that I can see, checked fine. Is there anything else to check?

After a power surge if you dont have in on a surge protector it probably fried the main board in the tv so it wont work anymore..woudl probably be cheaper to buy a new tv than to try to repair the one you have now

Intermittent picture. Lights on circuit blink when starting up. Often sound, no pic. Blue and blinking yellow for 2 or 3 tries, then picture. Sometimes only blue with no sound or pic. Ballast?

Ballast Board! Go to Encompass Parts Distr online find out what your Part# is! or Call 1-800-638-3328 also try UED 1-800-648-6657 This TV has alot of fuses over 20 of them!You didnt say have you replaced Lamp thats what goes first 9/10 unless you get power surge or Bad capacitors on the power supply Board caps are bad if they are puffed up on top 1000uf25v caps!

Toshiba 52 inch TV turns on then blacks out.

Unplug the power to the TV and HD cable box, wait 5 min. Plug TV and HD cable box back in.Everything is working like new. Go figure.

Power Surge at Home

This time it came in on the cable, the clue was the cable box also blew. So if you had a cable surge supression device...for HDTV, I think you would have survived the second surge.

I do have the technology. It is a F-connector type and will handle HDTV signal.

If you live in an high altitude area it can cause a plasma to hum.
Another thing you can try if you don't live in an area like that is using a surge protector. The thing is your power outlet could be sending what's called "Dirty Electricity" to your tv that could be causing it to hum. I would recommend something that does "power filtering" like a Panamax surge or a Monster surge.
So that you get clean power to the tv

Hope my info is useful....
Thanx for using fixya......

Found out from Toshiba that the yellow flashing is the cooling fan has stopped working. Replace that and you should be fine.
