MXL2 on a V4: won't boot DVDs.
MXL2 on a V4: won't boot DVDs. –
As I've mentioned in the thread title, my PS2 won't read DVDs.
I installed the MXL2 on my PS2 with 30 awg kynar wire for everything except power and ground. I used 24 awg on those. After I plugged it in, the thing wouldn't boot DVDs at all. On top of that, the laser, which I recently replaced, made these horrible sounds! It went like:
- Three loud clicks.
- Spin up.
- Motor stops, then click, click, click....
- Spin up.
- MASSIVE grinding noises.
After that, I looked for bridged points, solder balls, and the like with no success.
I even removed the chip and all the wires to no avail -- it still doesn't boot original DVDs. I did try adjusting my laser's DVD pot between 771 and 1091. It booted at 1091, but I didn't want to push it any more. I'm at wit's end here...
Thanks for any help you guys can offer!
Ummm.....Yah....Help is right.
First any DVD problems should be checked as follows:
1. Bridges to the CD/DVD controller chip
2. Fuses, sometimes if there was a bridge it blows a fuse (now you have 2 problems) fix the bridge then replace the fuse.
3.Check the BA chip, To check it for defects, test pin 8 for ground (that's 8 pins away from the small dot on the chip) If you find ground (it beeps) then the chip is blown. (the BA chip says BA**** on it)
4. Test the board to another disk drive (this is why you bring it to an installer in the first place)
5. Adjust the pots. See how long it took us to get here. This is the last thing I do when trouble shooting this kind of problem.
Adjusting the laser is DANGEROUS and TECHNICAL. The way that is described in these forums is known as "blind calibration", and could leave your Ps2/laser useless (too much power to the optical lens and it breaks). I do my calibrations with a digital scope (worth $5000.00) that I borrow, and only if I have to.
And you were saying that you "didn't want to push it anymore", the level the pots read is the level of OHMS (resistance), the greater the number the LESS power the laser is getting. And always make mark of the first value so you can turn it back if you have no luck.

DVDs works before chipping ???
What points do you use for b,i ( front or back ?? )
CDs works ( and cdrs with chip ??)
If cds works is NO BA chip or fuse problem ..
If works i bet for dead laser diode .
Well, I looked for bridged pins and solder balls again. None there. Fuses all checked out fine (continuity), so I looked at BA5815 pin 8 -> ground. (No continuity.)
Pin 8 on the BA6664 is linked to ground (mentioned many times in the forum by EnTiTy), so I don't know what that proves.
Other than that, the PS2 functions normally. It just has a hard time reading discs. Maybe another replacement laser is needed?
CDs work ??????????????????????????????????
Yes, original CDs work. The chip is not soldered to the board any more, BTW.
Then NO ANY BA CHIP FAULT.
You have a dead laser
