weird laser? lowest resistance?
weird laser? lowest resistance? –
on my v14 gh-040-12 i am experiencing very strange laser-behavior. I first installed a XIII-laserfix, which worked fine because the test-method did what it had to do. After that, we installed a crystal 1.1. now, the laser-unit wouldn't let the discs spin (none at all, ps2 just gave "no data" on browserscreen)
Next, we removed the XIII and gave the crystal a 3rd ground. As if by magic, discs started spinning again! well, only cd's kept spinning, dvd's were not accepted. so we installed firmwarerev 19 on the chip and on the memcard, hoping dvd's would spin again.
well, after a lot of cleaning and lowering the dvd-pot to as low as 350 ohms (default 1000), we still had no luck getting dvd's to work. There was no progress in laser behavior either, it just tries to spin up 5 times, then spins a bit, then shuts down again, while making this ticking noise with the laser, constantly seeking. cd's however work fine, even ps1-backups play from cheap arita cd's that have been laying around for some time...
now, on to the questions
anybody knows the problem?
anybody knows the (preferably costless) fix?
can a laser-dvdpart be burnt, but the cd intact?
which fuses can be the problem, if any, and where do I find them on this board (and where can I buy them in Europe, preferably cheap, preferably fast delivery)?
have you tried putting the laser back to what it was and removing the chip and wires? the noise sounds like the laser's not able to read anything, could be mixed up wires or a short on one of the chip points.
what colour is the led on the chip? if it stays on after a few seconds something is wrong with the install
it is possible to have a laser that fails with dvds but reads cds, unlikely on a brand new ps2 though
if it's not spinning at all check fuse PS13 - it's in the top right corner of the left half of the board, looking at it with the controller ports towards you on the same side as you fit the chip
well, we replaced it with a brand new laser (not "neofixed") and the ps2 has been playing everything ever since. so i guess, thanks neofix, for "fixin'" our v14 laser
