I have an old 50" plasma, LG 50PC3D. The symptoms are: sound is OK but the screen flickers several times per second... white, black, white, black, etc.
So far I have found the following:
- Fan works
- no ticking sounds from any boards
- no visibly pregnant caps
- 5V is at 4.98 VDC
- Vs is at 197 VDC
- Va is at 59.7 VDC
- ZSUS heat sinks are both warm
- Top YSUS heat sink is cold
- Bottom YSUS heat sink is warm
I don't wish to spend much time or money on this TV as it is a 10-year old model. What do you experts suggest may be at fault?
