| Power Supply, Horizontal output and Vertical output are the most failure prone areas. | |

|
| 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? |
