Hey guys, I just got myself a really good condition Version 9 PS2 and installer a crappy Super-7 E17 chip in it (most likely clone) and had alot of issue with it not powering (light would turn green then quickly red). After I fixed the VCC point (made a mistake) the ps2 booted to the menu and then I'm not sure what happened (the ps2 was not fully assemble) the screen turned black and you could still see the outline of the menu item. To make a long story short, I had black screen since then and erratic behavior. Sometime I could press power and have the green light but no image and clicking laser, sometime it would have no light at all. I completely removed the modchip and wire, cleaned all the point with desoldering wick and clean everything good with isopropyl alcohol and pcb cleaning brush. Double checked every inch of the board and checked all the fuse I could see but the Ps2 still won't boot. The Power light is kinda flashing a shade of yellow (not really flashing but you can see constant change of brightness lever in the LED). I'm completely at a loss and it wasn't my first install either. Back in the days I modded about 20 different consoles (and had to fight with some of them a couple of time to have them work properly:P ). I'm pretty disappointed because I just got this PS2 yesterday and it was a super good condition with barely used laser. I was very excited to have another Playstation 2 again to play all the game I missed but now it seem hopeless.
Anyway, sorry for the long message but I really hope someone can help me with this, it's not like it's worth alot of money but I'm pretty bummed to have messed up.
