Re:Comatose JX3P - 8051 CPU issue?

2009-02-28 by scott frye

Is the 8051 socketed?..If so..pull it out and put it back in.
Also ,if socketed, solder the socket leads while the chip is out.
If not socketed , solder the pins on the IC.... lightly though and switch sides of the chip when soldering each lead so as not to overheat the IC

I hope that helps
