Tuned the pots and it is now spot on.
Can't believe I spent hours on this and it was fluid under the chips.
Live and learn!

Amazing, I thought the board was clean!
I did what you said and it's working, like you it did take a couple attempts.
I just need to tune the laser a little more but most of the games work fine.
I get a whistling noise on two games when they are trying to load.
Thank you!

Are there any checks I can do on the pins, to see which chip it might be?
I've had a torch shining through the board but I can't see any damaged traces.
The only chip I could attempt is the 106, the other two I would probably kill the board trying to replace.

When I try a game it will start spinning the disc but then it stays on the please wait screen.
The laser moves, I assume to track 2, then returns to the centre of the disc and keeps doing that.
I some times get the ''load error "message.
I'm trying genuine games that I know work fine, I have tried using my arcade system card but the same thing happens.
Hope this helps?
Will adjusting a specific pot make a difference?

Could you help me?
I have a duo that plays music cd's fine but I can't get it to load a game.
I have recapped the board, raised the spindle and fitted a new lid switch.
I've tried three lasers but I get the same results with all of them.
The board was very clean with only a couple of leaking caps and all the pads seem to have cleaned up well.
Do you think this May be the cxd chip or have I missed a more obvious fault?
When playing music it plays the last song all the way to the end and if I choose the random track feature it finds the tracks with no problems.
I'm not sure what the display is supposed to show but I can see the track number, the length of the song or album, I can switch it to time remaining and the L/R stereo lines look like they move with the music.
Hope this is something you have come across before?
