PS2 Shuts itself down at Random

[bigfeat]

PS2 SCPH-3901 w/ Apple v2 chip installed. The unit shuts down at random times with or without game loaded. It boots up all games fine including backup DVDs. Anywho, after a few minutes or so the system shuts down at unexpected times. The reset button first starts to blink red at quick intervals and then unit stays steady at a sold red light. I then have to hit reset to start the sytem again.. Kinda similar to a PC power save mode except this does it when you're not expecting it.. Can someone help on this one?

Is your fan running? Sounds like its getting hot.

I didn't check if the fan is running.. But I assumed, it's not damaged. With a heating issue, being that the PS2 goes into standby mode, could it be a modchip issue or a PS2 issue? Because i can hit Reset and the game loads right back up, I'm wondering if an overheating mod chip can force the unit to go to Standby mode or if the unit itself can force itself to Standby mode in order to conserve energy... I'm I far off here??

Yes it can. And if your modchip is under the colling plate it may be stopping it from going all the way down in order to cool the components.

The chip is mounted along the wall of the case.. No components are in contact with it. Has anyone seen there unit go into Standby mode at all?

Fan is running and actually secured with some electrical tape... Does seem like overheating issues.. But is that overheating on the pcb because of the chip or could the chip not be grounded enough??? Better yet, could I have screwed up the chip bad enough to cause it to force the pcb to overheat?

The fan is not working at after all ... It was a new unit. I will disconnect the chip and see if it's preventing the fan from spinning... The fan does have current running through it tho. .I checked the leads. The thermo sensor just aren't firing the cool igntion signals. I will Have you seen this before. Or better yet, any idea on which part of the pcb is responsible for making the fan work.

Check the wires on the fan. You might've crimped and broken a wire while you were closing the unit. I did that myself when I installed a magic2 chip. The ps2 was doing the exact same thing as yours: turning off at random. So..... check the wires.... make sure they're intact.
