Need to repair a Yuyang Telecom YP2632T 05.02.16 rev A.2 psu for a LG 26LX2R tv

(1/3) > >>

Teza:
I have a LG 26LX2R lcd tv, thats now dead.
Normaly you can hear the relay click when turning it on, but not a sound anymore.
The led in front of the tv was working but not possible to get it out of standby mode.

I have opened the tv and there is an Yuyang Telecom YP2632T 05.02.16 rev A.2 psu inside.

From other posts i see that the first thing to do is to check the +5V standby, and it's providing +5V.
There is no other outputs that's works.
All capacitors look good and there is no leaks.

I know I have to short-circuit (?) a PC-psu to start it, and have a feeling that I need to do the same with this one.

Anyone that can help me in what to do next to find out if this psu is faulty, and how to repair it?

Sorry for my bad english and lack of knowledge of electronics.

waxhead:
are you getting the correct voltages out the psu, do they match with what is stamped on the board by the connectors

Teza:
No. I only have 5 volt standby from the board.
Have a feeling that I need to connect this output to another wire to activate this psu, but don't know how.

Thanks.
Have seen this set, but how can I be sure that it will fix my problem?

Any way that I can test them before ordering new ones?
