VERY strange CC-1.1 V4 Problem

Hi guys.
I have a PS2 here from someone who sent it in for chipping. It is a V4 and I have installed a Crystal 1.1 onto the motherboard and the install went very smoothly, all my connections are good, the wires are short, and everything checks out perfectly fine with the multimeter. So, I masked everything up, screwed it all back together, powered on, tested an original PS1 CD, DVD Video and its fine. I attempt to try an original PS2 DVD and it attempts to spin it up, does so successfully, screen goes black................ and we return to browser screen showing an 'PS2 DVD.' It was fine prior to install and booted EVERYTHING perfectly. Firmware CD will simply go to RSOD.

So, I check everything again, and as I had already confirmed, everything was perfect. So, at this stage I thought I could be here all day trying to diagnose this, and so I ripped the whole thing out, took apart a spare V4 I have lying around and decided to install it to that board. I do so - using fresh wires and everything - it all checks out, put that one all back together and guess what - on a 2nd V4 console, it has EXACTLY the same symptoms as the first. Once again, this console also worked perfectly prior to the install.

As I say, it all checks out continuity wise, its a neat install, the chip is mounted as standard on a V4, I have modded lots of PS2s but this has me beaten. All I can think of is a faulty CC1.1...

If anyone has any ideas, or can confirm my suspicions then that would be most helpful. Thank you...

It's OK guys I realise what I've done. I've actually grounded the TO wire like an idiot. I'll put the wire in its rightful place in the AM. Shows what you can do when you're tired, eh? ;)

Thanks anyway :)

LUFC!

Did you get it fixed?

I've also installed CC1.1 on my V4....but once installed the firmware and the bootloader my PS2 has become blind!!! It ony read original cd/DVD, but no writed cd/DVD. So it is impossible for me to upgrade the firmware once again-....sigh....

A question.....on the official installation manuals for the PS2 V4, on the top right of the paper is there a reference for a (yellow marked) point 5!!! Do you know wat is it?
Thanks

The "5" is indicating an area on the back of the V4 motherboards that has alternate locations for the CDVD points. It appears they decided to not include the alternate points is all.

As for your problem microphone sounds like you might have a laser issue. Recordable media by nature is simple more difficult for any laser to read then pressed originals and also the V4 is old and had a weak 400B laser to begin with. Perhaps your laser just isnt up to par.

Thank you spedmetal.
Could you suggest me how to fix the laser problem?
Are there some guides about this task!
Thanks

microphone - did you install the hacked firmware? if not, it won't boot cdr/dvdr games, but it will boot a firmware upgrade disc so you can put the hacked fw on.

test it with dvdr movies and cdr audio, they should work even in an unchipped ps2.

Hi Sped.
Yes, as suspected, that was indeed the problem :)

Right on bud :D
