Hi Jorge,

You may need to go back to Epson to ask if they sell this kind of board. I'm not sure how does your diode look like as sometimes manufacturers can shorten the part number. For example STTH3002C can also be TH30:

It has power but no lights come on? If you play something through does it give audio? I always end up getting my help and parts from www.shophimmy.com or www.hdtvparts.com but I will do my best to check back here and help you out.

I had received hitachi DLP projector having complaint picture flikker and colors system change when heated.

first of all, i removed Lamp and set prepare for blower servicing. after that i checked Loose connections and retest but no success.

after that i decided to un- assemble Camera and color wheel in order to service by Lint free cloth.

Precautions: make notes when trouble shoot these type of discrete equipments in order to assemble . makes posible to wear wrist band under off circuit troubleshoot.

After complete service i retest DLP projector again with Video and found that fault has been removed and no display flikker under 2 hours checking.

The main reason of fault was Color Wheel and Camera Glass was dusty and not clear for light signals.

Remarks : problem solved and payment done by customer.

Thanks you
Amir Mukhtar
