I thought it was the power supply but it appears to be fine as all + 5 V +12V -5V and -12 V measures correct from plug and back of the motherboard. When switched on, speaker clicks but no beep, no power light or display. I can feel heat when I touch 6502 and the roms but ram chips all cold. I have also reseated all the chips. I am now stuck at what to try next. Any pointers would be much appreciated.
