Hi, I bought a Philips PC-3100 a few years back, inside the case is a Corona XT, outside the case is the Philips Electronics Logo. Over the past year I have been having a persistant power-up error: If the computer is allowed to cool down, it starts its diagnostic tests ( 1 beep ). Then it aborts them about 1.5 s afterwards ( 2nd beep ). During this time both displays show an un- changing mixture of characters most in inverse video some blinking. The video pattern survives even a cold reset ( via reset button at the back ). After ~30 minutes a cold reset starts the comp- uter but it locks up almost immeadiately. About 10 minutes later the cold reset will again work and the Philips operates normally until the next power failure. It has been in service twice and the only apparent change was the bios version. ( Now Philips BIOS Version 3.3) System Configuration : 8088 4.7 Mhz 8087 " 1 Serial & 1 Parallel Port Philips/Corona Monochrome Monitor Graphics not IBM Compatible ( OK for text) IBM CGA card for IBM Graphics Western Digital Hard Disk Adapter 10M Hard Disk ( Seagate I Think ) 2 Epson Half-Height 360k Drives 150W Power Supply If anyone has had this sort of a problem before or anyone has an idea which component to pick on e-mail me a reply, if there is sufficient interest I will summarize to the net.
