WORKING!! Looked for corrosion around SPI, none, but found some around U5110! Replaced U5110 and ran a trace from pin 1 to C5120 and working! Thank you aprendiz for your prompt reply and help. Much appreciated!!
U5110 can only cause a completely dead machine. Something else that was heated up was the issue, so the problem may return. Corrosion under J6100 is common.
