weird laser problems - maybe charlie_ps2 can help
weird laser problems - maybe charlie_ps2 can help –
I have a weird laser situation. I have a v4 ntsc machine datecode 1A that previously had a neo 2.2 with capacitor. After some time my laser started to be less reliable, and I replaced it with another one and the ps2 was reguvinated. A couple of weeks later I decided to change my neo 2.2 for a magic 3 homebrew. I first took out the neo 2.2 and played some originals. The laser worked perfectly just as it had performed with the neo 2.2. Then I attempted to install the magic 3 and had some issues due to incorrect fuse settings on the chip I burned. To make a long story short I ended up taking the chip out, but now the laser acts very strange.
Its not like the laser is weak as it was in the other laser I wore out, It seems like it takes it quite some time before it even starts trying to read the disk. It spins slow searching for the groove for quite some time and then finally after being at the browser selection screen for 20-30 seconds(not in the browser itself, but the one that enables you to enter the browser) it boots the game everytime with no clicks or stutters. The other laser I wore out would spin up fast not find it...then spin up fast and not find it...then spin up fast and find it or not....If it didn't find it, it would get a disc read error otherwise you would get lucky and boot the game. This laser boots everytime....it just takes it a ton of time before it starts trying. I think this is not allowing my m3 to work properly(the same condition persists if the chip is in or not).
Maybe charlie can help...
My instinct is that the Homebrew installation wasn't right and there were solder balls or solder bridges left behind, or some other aspect of installation such as cables isn't right. Or the PS2 has been run with the top off and no heat conduction away from the BA58 & BA66 chips for more than a few minutes.
I've checked over and over again for bridged points...and have found none...I checked for continuity on the dvd controller chip and found no bridged pins
The machine was run for more than a few minutes with the top off....so I may have messed up the BA58 or BA66 chips....do they actually get that hot? Could I replace them from another motherboard?
Thanks for your help
They have heat conductors on top of them (if they are gone then they have almost certainly overheated). The conductors take the heat to the metal cage. The BA58 is particularly sensitive - it is a 12v chip.
