This set came in as a lightning damage set? The fuse it not blown. I did find a 3.9 volt zener diode shorted and small transitory defective. These parts are in the power supply section. I do not have 5 volts to the EPROM so suspect this as one of the problems. Hoping some one is familiar with this chassis or would share a print. thanks Bruce.
