Compaq Prortable won't turn on; no CRT; no floppy light.

The item I'm asking about is an original compaq portable; it turns with only fans, but no crt OR floppy drive response. I've seen others with this problem but no answers. I don't know anything about this unit's history, but may be able to find out. Any help would be much appreciated,

Harper Chisari have you opened the unit up yet? Checked all the cable connections? First thing to check is the power supply and the power button. What have you checked?

I had to replace some dead capacitors on the power supply board. It took a while to find which ones were bad. My compaq powers up now but nothing displays on the crt. Probably some more capacitors on the crt board.

For the floppy drive, lubricate the rails and clean the heads. For the CRT, replace the motherboard. For more information, check this video here:
