Melted down HD7 laser in a V9 ???? How come ??
9 months ago, I installed the following in a V9 (SCPH-50004):
- original Matrix Infinity
- Romeo mod, disconnected 12V of LA6508 chip, connected to 5V, just like I did it in a lot of V9's.
Suddenly it did not play anymore, originals/backups CD/DVD it did not matter.
The motor did not spin the CD/DVD's anymore.
Opened the box, checked the laser and saw that the HD7 laser lens was melted. Really melted. Never seen this before.
It looked like a melted down PVR laser in a V12 without laser protection.
I measured the focus and tracking coils of the HD7 laser, and both were on 0.6 Ohm. (between pin 3&4 and between pin 5&6).
Checked all the wires, and all were installed correctly.
What do you think could have caused this problem ?
