PS2 v7 dead after instaing mod-chip
PS2 v7 dead after instaing mod-chip –
I tried to install modbo 760 into my PSCH-39003 Playstation2. At first I got no modbo logo, after some corrections modbo logo appeared, I could enter configuration but no backups nor PSX (original) games were played. At some point after restart screen went black. I desoldered modbo, but still nothing.
Now I have no video nor audio. There is power on board - leds are lighting console is powering up, laser, CD/DVD spinning and laser carriage seem to be working so BA* drivers are probably good. I checked some random major fuses and they're OK. There aren't any shorts on the bios pins - I checked for them. There is also connection with pads on bottom side. I tried checking connection from BIOS ROM to HDD Controller, but I've got only SCPH30000 service manual (does anybody have 39 series service/schema?) and when I checked for one connection it was strange cause it seemd like some address wire on ROM (SA19) was connected only to line meant to be data (SD3/4 I don't remember) but maybe I just checked something wrong.
I could try to put console into test mode but I can't find TEST pad and also It seems to be ROM problem so test mode probaby woud ive me nothing but well nown black screen.
What should I check? Does anybody have any suggestions?
Try without the chip installed.If it´s works then it´s a install problem.
Double check the B.G.H.I.A.(F) points so there isn´t any that are switched.
Thats the most common problem with your symptoms.
Console is dead without chip. I dismounted it right after screen went back.
I checked pins You mentioned and everything looks fine - no shorts.
I also checked data bus and all low 8-bits are good - there is clear connection between ROM and HDD Controller. I also checked neighbour pins - they're fine too - no shorts, connection present.
I'm stuck - it doesn't look like some kind of short on BIOS pins but what else could went wrong? Maybe some chip is broken but which one and why? Is there any sense in trying to put console into test mode (I would have to find test pad, but I don't have schema for V7 :/)?
I'm thinking also about taking mainboard to work and making some tests with osciloscope - I could check then if anything is happening on the buses.
