Laser acting strange, NTSC v10
Laser acting strange, NTSC v10 –
A week ago I successfully installed a Matrix Infinity in a PAL v7. Today however, I tried an NTSC v10, and ran into some strange problems.
I applied the romeo fix to this machine some weeks ago, and it has been working perfectly until now.
After installing the Infinity, the machine boots up as normal, and displays the MI startup logo as usual.
My problem is that it will not read any discs. The laser makes a couple of clicking noises, and then stops. I opened the DVD-ROM to have a closer look, and it seems that when switched on, the laser immediately moves to the topmost position, (it actually touches the disc) a little down again and then finally back up. The disc never starts spinning.
I tried measuring the resistance on the coils, and both read ~5.5 ohms.
I figure I have made a mistake somewhere in installing the MI. Do you have any advice as to what I should check?
if you've checked all the wires and none are loose I'd remove the mod and see if it still works. Otherwise it could be a dead laser. Does it play music CD's or PS1 games?
Thanks for your reply.

It doesn't read anything, as the laser won't move properly (in the up/down directions)
It seems unlikely that the laser would just die after installing the MI.
I'm guessing the laser coils somehow are getting too high voltages, and this causes the laser to move too far upwards. How this could have happened, though, is beyond me.
I guess I have no choice but to unsolder the wires and see what happens. First I'll try to unsolder only the ends that attatches to the chip, as I really dont want to do those tricky bits on the motherboard all over again.
I figured it out at last.
Somehow I managed to solder the SX wire to the wrong capacitor...
I fixed it, and now everything works perfectly!
cool - there's always something that catches you
