Burnt pstwo, how to repair

**dam76** · 05-15-2005,07:15 AM

Hello,

I killed a pstwo with a matrix infinity and summeone fix (i dunno why btw, solering points were good).
I found out that ps14 fuse was dead and replaced it, and now it's booting but can't read any disks (dvd don't rotate but laser is moving).
I saw that laser was burnt too, and replaced it but it still doesn't work.

What else could be dead ?

Thanks

Did you check all the other fuses?

Check the resistors where you applied the summ0ne fix

All others fuses are good of course.
Resistors seem to be good, but i'm not sure. I got 683 (68k) resistor for which tested value is something like 42,5k on mainboard. But if i desolder it, its value is 68k so i guess it's not the problem (?).

Did you remember to re-connect the white flat-cable for the dvd?
I forgot to do that once and the thing booted, laser worked, but no spin.

Yep that's one of the first things i checked.

First check ribbon cables.Check specially ps13 if disc not spin.Then I have a problem(lens go up hardly then stoped up) when I measure this components(all resistor) with digital multimeter give me right result!But when I remove it ( I show it in attachment)I see it is blowned?

make sure that the resistor readings are the same of the resistor rating
