That looks identical.-part no srv2169ww-mitsumi

I've done dmm checks on diodes & fets and drwan a blank.
I wondered if it might be one of the 2 tansformers.

Does your board work? Wondered if you could give me input/output voltages off these transformers.

Hi CB, you mentioned that you have the service manual and you say that it has no details,do you mean that it  does not contain a diagram of the power supply? The reason i ask is that i have a 37AV554D  in for repair which may have a faulty power supply but i have not been able to obtain a service manual for it.

Thats right the manuals neither use nor ornament. No chance of component level fault finding. I wouldn't buy this product if I had a choice.
