HELP ps2 not working

HI, i recently open a ps2 and installed a messiah 2. At firts, it was working then the dvd started making a weird sound and was opening and closing very slow. I turned off and back on and now it doens't read any dvd, not even original. I decided to unistall the mod and it is not reading anything.
did i fired the dvd???
(ps2 v 7)

thanks

couple of possibilities - pinched wires - that eventually shorted...

knocked off the heat transfer pads that fit between the BA chips and the metal plate making it overheat and eventually fry.

When you opened and closed it - pinched the reset cable...

you didn't adjust the laser did you?

A small hiarline short on a chip leg from solder splash...

either way sounds like now a fuse is blown or one of the chips / cd drive is blown...

When the tray comes out REALLY slowly, I think it is the BA58 chip. This can be located at the top left of the PS2 main board (depending on how you look at it). If you have a multimeter there, put one end on pin8 of the BA58 and one pin on the ground (outer orangy/brass coloured areas). If you get a reading from this, it means the BA58 is fried, also check for bridges on the bios and check the BA66 chip.

Hope this helps :D

PS. I know this can be very frustrating at times, but do NOT give up, I just went through a tedios DMS3 install, which eventually worked. If you want to check out my review click here

Hope you get your PS2 fixed ;)

thanks guys for the heads up, i will try tonight and post the replay..... anyway, now the tray is opening and closing fine the only problem is that is not reading anything

thanks
