V9 is driving me mad (Black Screen MXL2)
I have done a couple of hundreds chip's instalation on the PS2, since the arriving of the Neo 2 then Neo4, Messiah 1, etc. Starting on the V3 model. I never had any problem (except normal ones: faulty laser lens, dust on the lens, etc) with the PS2 models before the V9.
But now this V9 is becoming very problematic, i have done 8 chip instalations on this model. In 6 of those consoles i have installed the Matrix MXL2 and in the other 2 i have installed the DMS3 clone (R****R 2 Deluxe). And in 3 of those i am getting the black screen problem. And the symptoms are always the same, the console starts working normaly and after some dics tests or playing it freezes. I press reset, reset is done but all i can get is a black screen. Everything seems to be working, power button, reset button, tv detects the signal from the console. The only thing that is unusual is the fan that starts working only after five seconds or so. When i uninstall the chip from the console the problem remains.
I have read the forum a lot to see if anyone is having the same problem, and seems that the problem i have is a ground bounce problem. How can this be solved ?
I don't think the problem is a bad instalation, because i had checked everything: continuity, bridges, fuses. I solder the B, G, I spots on the VIAS and to see if they are ok i do a continuity test between the points on the chip and the legs of the CD/DVD controler on top of the board where we can solder also the B, G, I.
Also doesn't seems to be faulty chips because one of the chips that was installed on a V9 that was giving me problems, was installed on a V7 and it worked fine.
I contacted my chips suplier and he said that my problem can the be the BA chips, but i never had a BA chip problem with ther early models.
Hope to get some feedback from all you. Tks
