I have more photos but the forum will not allow me to upload hires images, just 800x600 and you can't see the traces. I may have to host the photos on another server.

Are these useful to anyone? I have more.

This board is very small, as far as I'm concerned. Are they all this tiny?

Hi, you can use online storages like http://tinypic.com or other and post the links here.

If you can zoom around R135 and R136,
and also around the left side of the heatsink (in the shadow on your 2nd picture),
it might help.
Try to locate a resistor with a pad that is not connected to anything.

Thanks for the replies juuso and oga83!

Here is a zoomed pic, I'll try and take a better one in the next while if this is too blurry.

It might be R131 and the resistor just close to it, but the photo is not clear enough.
I can't tell if the pads are connected or not.

It seems there is nothing around R135 and R136

Have also a look at the shaded area on your previous photo.
