got the ps3 no power issue (flip the switch in the back to on, but the power control board gives no standby light and the touch buttons do not work)
a standard technique to use in this situation is to put a disc in the drive, which force boots the system since it's powered by the psu separately from the mobo
except that didn't work for me on this system
it doesn't even try to bite the disc
1) replaced the PSU with a known working one and tried again, no effect
2) replaced the blu-ray drive with a known working one, again, no effect
3) replaced the power control board, no effect
very curious, especially considering that the blu-ray drive originally in the system displays the same problem in every other system, but when you place a working drive in that original system, it shows the same symptoms as well.
