Hello! I am hoping someone can help me here. I have a Compaq CDS 520 that's new to me. I've done all the usual troubleshooting steps including deoxit the connectors, re-seating the ram and processor, checking the caps for leakage, checking the traces. I can't get the screen to show the output. When I power up, the screen comes on, but it's all purple, i turn up the brightness and it goes all white. I've adjusted the internal POTS as well for contrast and brightness. I can hear the system booting. It beeps twice, then pause, then again so I press F1 on the keyboard...it restarts and i can hear it booting up. Just nothing on the screen.

Thoughts?
