Help fixing Panasonic TNPA5808 low voltage issue
|
Can't Post
|
|
I'm trying to fix an old Panasonic LED TV, mainly for educational purposes.
While I was checking voltages on the P-Board I got to know the voltage of the SRV-16V rail is 13.2V (with and without dummy load).
Both 16V and 24V rails are bit lower than specifications. However the 5.3V standby line is good.
I have tested diodes, transistors and some other parts and didn't find any issue. This seems beyond my knowledge.
Please help me to solve this issue. Thanks :)
