Hi sir;
Normally test the power supply from Vdc, must be in range of 0.7% up or down. otherwise, the console will NOT work.
However if the voltages are o.k please do this;
1) Perform a visual inspection : look for loose and broken wires, improperly seated connectors, loose or broken wires
misset switch, missing jumpers. and so on.
Chech for obviously damaged component(components burned or discolore due to overheating);
Dust + dirt + tear +wear
2) Reseating Boards and components:
Edge connectors are a common souorce of problems. Power down the system and remove the PC boards. Examine the edge connector
for contamination and clean with contacts cleaner contacts. Reseat any loose components such as scoketed ICs) . Reseat the
boards and power up.
3) Power supply checks:
Check the power supply for missing voltages and voltages out of spec. A digital multimieter DMM can be necessary, as
voltage specifications are quite tight: logic supplies for example: must be within + 5% percent of 5Vdc. All the
multiple supplies and all must be checked.
4) Board swapping:
Board swapping involves the substitutiono of a known godd board for a suspect one.
