if the blue button does not light, its blown ps11, betchya, if they both light up, its likely something bridged on the bios chip. I have fixed lots of these (cause in the early days of the days I modded, I managed EVERY possible way to screw up a ps2, and had to learn how to fix it), but I wont even tell you to do that, its brutal, and requires straight up balls to do right. You have to DROWN ALL the legs on the chip in molten solder, then solder soaker (de-soldering braid) it all up at once, and FAST so you dont burn it all up, need a soldering GUN, as opposed to an iron, to insure that any solderballs and bridges behind the legs get sucked up and out.
Its a 50-50 thing, but its better than a black screen, so you have nothing to loose trying. just dont blame me if it fails, this is a hail mary, at best. I will say it worked most of the time I did it.
Tell you what, send me both with chips, as is, I'll strip the lazer out of your v7, stick it in my old v7 (needs lazer) and send you that, as is. It works, chip or not, the board is good, for a v7. I hate the damn things, and scored a v4 no read for $20, last week, so you see what happpened there, right? I have been considering a chip in my new (really old) baby, since this one is a keeper, since it is not a v7 or later, as I said, I hate them. A 35001, cool, those ALL came in a big, red, bundle-box set with a steering wheel, and GT3, new. Last of the v4's. Keeper. And now reflashed for an R lazer, its what I had. Its been a while since I liked my console. Toss your mc card in, I fmcboot it for you and send it back with, maybe you wont want a chip so bad anymore, anyway. you pay send, I pay return, it'll be quick enough, deal?
A toxic agent on a dangerous mission so secret, even I don't know what it is, because if I did, I would have to kill myself. I don't even know who's side I am on.
