I thought I’d fixed my B&O CD3300, type 5142, as I managed to get it to play most of my CDs. I’ve replaced all electrolytic capacitors on the power supply, decoder board and servo board. But, after leaving it for a few days it now plays none of them. In most cases the TOC are read, but it won’t play.
I now want to check the laser power. The service manual says to put a meter across R3102 to check the mv. But, my servo board, number 5886 on the sticker, doesn’t seem to have that resistor.
I’ve attached pictures of both sides of the board and would really be grateful if someone could point me to the resistor. Yes, I know the blue capacitor by the 1K0 variable resistor is missing. I took the picture before I put it back in.

The resistor should be in the top right of my picture showing the solder side, just next to the 14 pin ribbon connector and not far from the 104 resistor. But, my board just has a gap.

I've found it. Turns out it is in line with the IC by the ribbon connector and not to the side. Turns out the CD3300 service manual has another servo board detailed right at the end of the book. I was looking at the 1st one in the book. I should have learnt by now to read right to the end before I waste people's time.
Now off to test the laser power output.
