Re: ptv780-ah01

Well, I'm assumig you've already attempted just turning it off and letting it sit for a few hours. I would also recommend unplugging it and letting it sit for a few hours before plugging it back in and turning it back on. These TV's have this problem fairly often, and it's normally a result of a bad flyback transformer, which is a part you need to order from the manufacturer. I would advise having a licensed repairman replace the part, because it is fairly difficult. Even with practice, things can still be broken.
The flyback transformer is the component that generates the large amount of voltage required to drive a CRT. If you decide to replace this component yourself, order service manual #7566 from Philips - it will give you a lot of schematics and tips that are very useful.

Here's my suggestion , unhook all the external components to the TV and leave the TV unplugged for more than a few minutes (a day/overnight). The next day plug the TV into the wall outlet (not the powerstrip) without anything hooked up to it, and turn it on. See if it comes on. Sometimes unplugging for a few minutes/hours is not long enough for it to reset itself.

The picture went from clear to snow, but the sound remained clea

Flyback is going out in this unit and would cost $120 for a new flyback if I were to repair it for you. So you have two choices have it repaired on recycle it! The repair these days on TUBE tv's are not very cheap because of having to find parts for them. Rulds2008

Good day,

Your problem indicates that there is an issue with the horizontal or vertical circuitry. Some parts may have been busted thats why your tv cant function normally.
I suggest you have it checked by a repairman,

No video

When you say no video, is there any light on the screen at all? And is there any sound?
