Hi.
I'm repairing an old Sanyo TV for a friend.
The TV wont turn on.
My friend told me that one he turned on the TV and heard a small click sound and the TV never worked.
I openned the TV noticed some broken solder joints, I resoldered every broken joint in the circuit.
Now this is what happens, I turn on the TV, the led doesn't come up and I hear a loud and irritating "skwiking" sound coming from the PSU area!
I tested, resistors, diodes and zenners on that area all appear OK.
It appears that the sound is comming from one of the transformers!
What you guys think?
Thanks
