Hello Eddie,

Repair as follows.

One of the CRT IC's is shorted. replace the shorted IC IC1101,1301 or 2101 on the CRT PCB's and modify the circuit thus.

Using a total of 3ea of part number QFZ0199-334 capacitor replace C1103,2106 and 3106 on the crt pcb's.

Using a total of 3 ea of part number QUY153-050Y replace the jumper wires Y1001BW,Y2001BW and Y3001BW on the CRT PCB's

This will keep the IC's from future failure.

Hope this helps
