VERY strange MI on V9 problem (colorbar???)

Using for 1.5 years the Infinity v1.75 without problems.
Now after not using my PS2 for 2 months (yeah PS3 sorry) i connected my PS2 again and it won't boot anymore.

What happend is:

Turn PS2 on.. red led turns green and blue led is on, after this the ps2 don'tdo anything (no video signal) for 10 ~ 15sec. Then the Matrix logo appear, but it wont boot to browser.

Trying to disable the modchip (press START) no difference, still 15 sec wait and then Matrix logo, after this nothing happend.

In the 15sec 'wait time' i'm unable to open the DVD tray, when displaying Matrix logo i can open and close the DVD tray.

Put a disc (backup, original, DVD movie, doesn't matter) in the DVD drive. turn off the PS2, turn on, after the 15sec wait i get the Matrix logo and 5 seconds later i get a 'colorbar' and a tone sound.

However, after turning the PS2 on, press TRIANGE+CIRCLE and wait for 15 seconds i CAN get into the configuration screen. I tried all the options, after saving my settings and the reset, no difference.


I get a colorbar JUST like the attachment (without the white border ofcourse)

Opened my PS2, checked all soldering, checked all wires, seems all OK.
Also checked all fuses, none are bad.
Reheating the soldering point, still same problem.

What can it be ?
Is my PS2 pissed of me for buying a PS3 ? ;)

That happens when the DVD authorization chip is dead. Looks like you're looking at a new mobo or try reinstalling the chip. Also make sure it's not a clone.
