Hello all, Recently I turned on my machine and it did not boot up. I checked the MPU (alltek) and none of the LED's were coming on at all. I tested the test points and did not have power at the 5volt test points's. I checked the schematic and decided to take a look at the solenoid driver board that delivers power to the MPU. I found that at the test points 1 and 3 on the solenoid driver board, I had no voltage (.07volts) and they should be 5 volts. Has anyone repaired a board with this issue? I am assuming that the voltage regulator on the solenoid driver board is needing replaced. TO BE NOTED: I did check the voltages and fuses on the power supply and they are fine. ALSO, all of the general illumination lights are coming on, but no power at the MPU. Looking for people to chime in on this issue.

Okay, just checked the voltage at TP5. NOT 11.9volts, only getting 2.5 volts.

Just checked pins 8 and 12 on J3 rectifier board. on pin 8, I am getting 11.3 volts. On pin 12, I am getting 45 volts. ?

Reseated connectors and checked voltages. I was able to measure the voltage at each point with the connectors on and I am showing 11.3 volts at pin 12 on the SDB and also on pin 8 rectifier board.

no volts.

I do have continuity at those points. Does that mean the cap is bad?

Truly thanks! I just checked the cap and it is not giving me a reading and I see upon observation a small amount of leak on the bottom. I am confident that it is the problem. Appreciate your help.
