My first guess would be the check the chemical fuses on the power board, they are white and small and are soldered through the board.. This will tell you which circuit the problem is in by knowing which ones are shorted. If I were a betting man I would look at the convergence amps first.

I turn on the power and get just a buzzing noise. The keyboard does not work at all. The power light is on but no sound from the keyboard other than a buzzing sound.


normally a buzzing sound means a grounding problem, or a component has failed, unless you have the proper equipment to check these items,, your going to have to take it to a shop that does, sorry I know thats not what you wanted to hear,, but heres a hint, Ive found that a shop that deals in instruments and sound devices charges a lot, I have found a TV repair shop in my town, that can check my band equipment,, and its much cheaper, and I usually get the stuff back much quicker too

Tv does not come on after pressing the power button, or using the remote. resetting does not help.


Does the green light just blink or does it come on for a moment and go off?

I need to know which to tell you what to do.

A hint--if the green power light comes on for a few moments and goes off do the self check this set has.

On the front of the set press and hold BOTH THE MENU AND INPUT (OR DEVICE) BUTTONS BOTH FOR AT LEAST 5 SECONDS.

If this is the case the power light will blink a two digit error code--most common in this case is 2 blinks, a pause and 2 blinks--it will repeat the code up to ten times.

Let me know if you find an error code or the power light just blinks and never stops.

If this helped you rate this solution as I do this here for free.

The Power/Timer light SHOULD stay green on a normal working TV. It sounds like the main board is either defective or has a connection problem to ??? (power supply, etc). All fans should be turning (a hint of missing power). Check ALL cables...be thorough.

Tv will not light up.


Your main fuse blew if its dead but it could have caused other issues with an electrical spike when the power went off, this is kind of common..pull the back, replace the main fuse and see if it blows it again, if it does then the diodes in the hot side of the power board are bad and would need replacing.
