need schematic

[Francesco Messineo]

Hello,

I'm looking for the schematic of the TV set Inno-Hit TVC 2140MS. It keeps
killing the horizontal output transistor each two or three power on.
Once powered on it stays on for days w/o problems. I think I'm lost
w/o a schematic diagram.

Thanks in advance.

A diagram will not help too much. Check the capacitors around FBT. If
they are OK probably your FBT needs to be replaced.

Well, I already changed all capacitors arount it. I'm going to change all
capacitors on the power supply part. I don't know why a diagram shouldn't
help. What FBT fault could blow the line output transistor only during
power on and not during hours of work?

Thanks
