    I encountered the same problem a year ago. Likewise I replaced both the transformer and the horizontal output transistor. It worked fine for about a year then recently it broke down again with the same symptoms and the output transistor is shorted again. I replaced that transistor and the set came on with just a vertical line, no horiz deflection and shortly the screen went blank and that hissing noise again. The transistor shorted again. Does that mean that the transformer is bad again and caused the transistor to fail or are there any other things that could it to fail?

I replaced both the Horizontal output xformer and xsistor. The set came on for few secs and then made that buzzing noise again. I unplugged the TV and checked the xsistor and it shorted again. If I have a schematic that would help tremendously. Again, thanks for your help.

the tv has one part of the power supply working this is needed to have the microcontroller ready to work. But the tv needs more than that for work im talking 'bout the high voltage power supply who is now damaged. the parts required depends on the diagnosis in the bench but at least two are needed. the cost of this repair of course depends in how many parts are going to be replaced, but i concider this repair kind of average in this technology.

Hello cote,

This indicates a problem in the power supply either the low voltage switching supply or the High voltage power supply. The sounds you hear is the shutdown circuit activating, I would not suggest that you try to repair this problem because of the dangers involved. I would suggest that you take it to a qualified TV repair shop. This problem should not cost you much, however it is the best choice for the problem you described.

I hope this helps,
Thank you,

You have a bad flyback transformer and shorted horizontal output transistor. Your set would have to be taken to a shop to have these parts replaced. Stargazer
