Missing blue

Sony PVM-14M4U.

Several of our Sony PVM-14M4U are missing blue signal.

Is this a common problem with these monitors and what is the solution.

We have 10 PVM-14M4 monitors in the system. Most common failures are CRT 11 times, C572, C584, C588, C590. All 10 have had capacitor failures. 3 monitors had 2 CRT replacements and one of those was barely a year old. GG

I will replace these caps and see what happens.

Thanks

Check the cables, connectors, soldering on the neck board, video output transistors or IC, losing a color is a common problem for any monitor.
