Hi there....

I have not too much knoledges about tv repair but I'm trying with my tv philips. As I said, it doesn't work, the stand-by led keeps off and there is a buzz that seems is coming from the power supply.

After to take a few measures I removed the horizontal output transistor because I thought it had became shorted (there was no resistance between every pin). I measured again after to remove it but it looks good.

Please, what else can I do ?
Can I try to take voltages values with the equipment turned on (Hopefully without the need to put the hands on the flyback ) ? Which values would be the righ ones ?

Thanks a lot and forgive my english.
Marco.

Replace the horizontal out put transistor anyways. I'd start there.
