My dog sat on the remote and the TV hasn't turned back on since. I unplugged it for over 12 hours and it did the same thing when i tried turning it on again. The power light flashes three times and the TV never turns on. I've tried different outlets and there was no noise when it went out. It doesn't work manually or with the remote.
This could cause a problem, because modern TVs and most other entertainment electronic goods, have a small kind of computer chip, but there should be a Reset button probably inside the set! If you feel confident about computer chips you may be able to find the button by tracing the circuit.(Disconnected from the mains). Another idea is if there is a small button cell or battery inside, then try disconnecting it for a day. Good Luck!
That high pitched noise you're hearing is the power supply telling you that it has too much of a load on it and lowered its operating frequency which in effect cuts its output way down! Normally you don't hear any thing since the power supply operates at a frequency that's beyond human hearing. In an RCA this indicates more than likely that your horizontal output transistor is shorted and this short was caused by the flyback transformer shorting. This is a common happening with RCA's You'd need to take to a tv shop and have it checked out. Stargazer
Ok you did not cause the problem as you could always turn on the TV set from the front panel button,, If the TV set will not turn on even with the front panel button, there is a major fault with the TV set. This is not a reset that can be done by the user as there is a circuit fault and will require you to take the TV set into a shop to be diagnoised or replaced. Good Luck
