Hello all,
I have been trying to fix my TV which has sound, but no picture.
I am not very good at fixing TVs, and was wondering if someone could help
me.
The power supply voltages are ok, and there is no life in the high voltage
transformer.
The circuit that supplies the transofrmer has DC but no AC.
As I understand it, it is fed by the horizontal out of the AN5607 chip.
I measured all the pins on this IC, but I don't know what to expect.
I have listed my findings below.
Can anyone help please?
Please reply to my email address:
Thankyou in anticipation.
Peter
