BN44-00496B A5V only have 2.2V

Troubleshooting TVs and Video Sources - Badcaps Forums - www.badcaps.net
Hi everyone,

I have this board, the output here only available 2.2V at the A5V circuit. Definitely this things doesn't powers up.

B5V

B13V

measure 0

LED connector at D1/DI+ give me constant 90V

So far, I replace optocoupler as the anode/cathode doesn't give correct reading. Also replace the SSC 2S110 out of trying.

Can anyone give me some suggestion?

Also I need the schematic for this board too.

I am familiar on laptop electronics, but not so much on TV powerboard.
