Your symptom description is vague?

Do you have any sound or any light on the screen when the power button is pressed? Do you see any light on the screen when the power button is pressed again?

I don't think that c423(1000pf/1kv) or r423 or r424 both (100 ohm 2w) has anything to do with the set not turning on.

If you see any light on the screen when you turn the set off, you may have defective solder connections on the vertical IC1500 (TDA9302H). Located on the metal frame at the back of the chassis. You should be able to see small cracks around the ic pins if they are defective.

Good luck,

There is nothing visible on the screen whatsoever. One day, when I tried to turn the TV on, the screen remained black, I could hear a faint ticking sound and there was a burning electronic smell. I opened the TV and saw the burn marks I decribed above. Prior to posting, I found another article on this forum that had a very similar problem....

"The other day I was watching tv I got up and went to the other room and came back. The TV was off and the room smelled like burnt plastic or rubber. The tv would not come back on so I unplugged it and took the back off to see if I could see anything burnt. The only thing is (on the back right hand side of the circut board) what I think is a capacitor. Its small, round, and light blue. When I plug the tv in and turn it on, all I get is a faint tick. Every 5th or 6th tick that capacitor flashes and burns a little more of the blue wrapping off. I can't tell what the specifications on the thing are because most of writing is burned off. Other than that, I see nothing at all."

you recommended that that person replace C423 -- which is curiously, near my burnt resistors. I hope this gives you more of a grounding to diagnose why the resistors may be burned.

Thanks again

Here is a link that might be useful: Previous thread I referenced in this email.

You didn't say that there was a flash from c423 before.

Just replace it, the resistors are probably ok.
