Re: lcd tv power supply problem
The voltage across the main cap is 167v dc. When supply is powered on that voltage drops to 150v dc. I have already replaced the other caps.

Re: lcd tv power supply problem
Hello,

Thank you

Re: lcd tv power supply problem
Do you mean the four caps on the 24v rail? What would cause the voltage to drop across all the dc outputs except the 5v standby?

lcd tv power supply problem
Hello,
I have a power supply from a Haier tv that i am having problems with what to check next. The supply is a AD301M24-4N1. The supply turns on but with it connected to the mainboard the outputs are low. The 12v shows 6v, the16v shows 9v and the 24v shows 15v. i disconnected the supply completely and jumpered the ps/on pin to the 5v standby and all the voltages come up to spec.
If I connect a load to any of the outputs the voltages all drop back to the lower readings. Could some please advise me on this!
Thank You for your time!
Jerry
