Question about Sanyo DS31590 31" TV
I have a pins cushon problem....
This is usually caused by failing capacitors in the pin amp section. Testing caps with an ESR meter is a good way to find the failed caps. Or, you can do it by replacing the caps by guessing. Or, you can use a scope and follow up for the proper waveforms.
While you are working on the set, it would be best to verify the caps in the power supply and scan amplifiers.
If the fault is more complicated than just caps, you will probably require the service manual and have to spend the time to troublshoot the pin amp circuits.
