Main Chassis Pcb Location - Mitsubishi Electric VS-45605 Technical Training Manual

When the mode is activated, the front panel LED
starts flashing a two digit code:
1) The initial number of flashes denotes the
value of the tens digit (MSD) of the code.
2) Flashing pauses for ½ second.
3) The LED flashes the value of the ones digit
(LSD) of the code.
4) The code is repeated 5 times, then normal
operation resumes.
The two digit codes indicate what malfunction has
occurred, or that no malfunction has occurred. Table
1-4 lists the two digit codes and their meanings.

Main Chassis PCB Location

Figure 1-5 shows the location of the PCBs, and ma-
jor components on the main chassis assembly. Two
major PCBs comprise the main chassis:
• PCB-MAIN
• PCB-SIGNAL
Circuitry on the PCB-MAIN includes:
1) Power Supply
2) Horizontal and Vertical Deflection
3) HV circuitry
4) X-Ray Protect
