V7 Strange Fault Any Ideas?

[fanta]

I fitted a ripper chip to a V7 all worked fine for a few days then
it stopped playing DVD-r and just gave the red screen of death
Checked all the wiring could not find any problem fitted a new laser still wont read DVD-r
so removed the ripper and fitted DUO again all fine for a few days then exactly the same wont red DVD-r
removed chip again plays original fine
i then fitted the ripper to a V5 3 weeks on all working fine
i then fitted the Duo to a different V7 all working fine
has anyone had this before it would seem to be a rogue V7 that just wont stay modded for more than a few days
any ideas??

hmm never seen this happen before. You sure the connections are ok on mod try resoldering it all.

went over all connection 3/4 times
iv'e had a similar fault once before a wire had come off the bios so take extra care and double check every time
i stuck a Messiah 2 into it last night all works at present
but only time will tell

check all point with a multimeter.

ive checked them all with a multi meter no shorts
iv'e been all round the board with a high power magnifying glass looking for solder splashes and bridges can't find a thing
its odd all the chips have worked fine for a week or so then
just seem to stop reading dvd-r games ,original ps2 and backup ps1 and dvd movies are fine .the same chips in another ps2 fine

wtf man! i dont get that it should be ok. Try looking at the cd dvd controller. Did you use correct wire? Also the laser might be something to do with it.

[fanta]

im using the same kaynar wire ive used on every other ps2
i tried a complete laser unit out of another ps2 didn't make any difference still working with the M2 fitted 2 days now ill wait an see its got me pullin my hair out

[seaneyb2003]

ok seems a bit odd to tell u the truth

[fanta]

Thats why i can't get my head round what its doing
i thought ok 1st chip worked fine for week then stopped playing dvd-r maybe a loose wire couldn't find a wireing fault so change the chip for a duo again about a week later wont read dvd-r
tried new laser didn't fix it so fitted both chips to different ps2 both work fine
it realy does seem to be this V7 doesn't like chips
