Question about Televison & Video
Television was working with perfect picture then all of a sudden it just shut down, not even the red standby light on, but it has a high pitched squeal coming from inside, I have opened it up squeal is so high I can't locate noise... the noise was not present before it shut down... any ideas on what is my problem. Before the TV turned off permenantly, the TV picture was distorted on one side - the right frame of the picture kept coming inwards towards the centre of the TV screen. Also, sometimes there was a discolouration at the centre of the TV after the TV was turned off.
What has happened is that the horizontal output transistor has shorted. The squeal you hear is the power supply running under a heavy load. The picture narrowing or being distorted indicate that the horizontal output was not operating clean. Something in the output section was not as it should be. Possible short in the output transformer/tripler unit or something loading down the secondary voltages generated by the horizontal output. You will need a tech to figure this out....If you are not a tech, then this ones a goner as far as fix it at home goes.....If you are a tech I might be able to talk you through the repair. Have someone remove the horizontal output transistor and I bet the squeal goes away.

You have a short in the TV. Probably a horizintal output transistor. They squeal high pitched when they short out. Unfortunately you must have it repaired by a professional service technician.
