ALS or non-ALS identify and blank screen
I just bought a fixer upper imac, it was sold to me as the g5 1.8ghz but I am wondering if it is the ALS version. There is only one button below the upper fan, and I thought on the non-ALS version there was two (one to turn the mac on, and one to reset the smu). Also, there IS the ALS hole in the botto of the case, which leads me to believe it is the ALS version). I bought a power supply as the imac didn't come with one (fixer upper, remember), and I did NOT buy as ALS specific powersupply (it was part #614-0366 that I bought, which I see is compatible with ALS imacs). Would this prevent the imac from booting? I replaced and have reseated the ram, and replaced the hard drive. I cannot get the computer to boot, just the chime, status light solid, and a blank screen, although if I turn the lights off I can see the lcd lit up a tiny bit. Should I replace the lcd, or could my problem be the 7 caps that look bad on the motherboard? When I turn on the computer with the back off, I do get the first 3 lights up on the mother board (kinda below the upper fan). To summarize:
1. would a non als specific powersupply prevent the imac from booting (I have not installed osx yet) 2. does a dim screen indicate at this moment a bad lcd, or 3. would bad caps on the motherboard prevent the imac from even lighting up the screen. Thanks in advance, I am pulling out my hair!
Is this a good question?
