  1. Hi, I have a 1.6 crystal, I'm the first to open it up, it has no life when the buttons are pressed, so far I have, Tested the power supply, and the power when the power button is pressed and held. I'm getting all the correct voltage when standby and when the power button is held, it tells me the power supply is doing its thing. The only one that is slightly out is the 12 line at stand by it shows about 0.34, when plugged on to the board but 0 when removed and just the plug probed. It had the 5 capacitors all leaking and bulging around the power socket, so I incorrectly thought that would be the problem and changed those for some panasonic units. Again this didn't sort the problem. I checked the transistor at Q7C2 and was getting 3.36 volts on the collector, but to prove a point I removed it from the circuit and put it on the tester independently it showed as a working pnp transistor. (I have ordered some new ones as it off the board so might as well replace it.) I have read that the clock cap can be replaced with a capacitor but now cant find the correct value, as a fault clock cap can prevent power up?? plus it looks like i may have damaged this one with the heat gun, could just be the outer paint coating scorcher on closer examination though, been unplugged a while and still showing 1.66 volts. The traces from the power/eject socket are good going up to the xyololops chip. cant see any corrosion on the underside of the board either. so that's where I am with it at the moment any suggestions on what to test next. I have a 1.4 board and ps that i can fit into this lovely case but would like to try and fix this one first. The board dosen't look dead flush where the cpu sit on it slight warpage of the board with the weight of the heat sink pushing down, this may be normal though. Thanks Ted
