The CGA display made by IBM for the PC/XT series of computers
Known Issues
Red or Blue channel brightness increases
Causes
- Capacitors on gain board are failing
-
The neck PCB for an IBM 5153 centered on C569 which failed
Solutions
- Replace C569 & C215 capacitors
Disassembly Notes
It's a CRT which should be discharged before working on it.
There are screws on top of the case under plastic caps.
The plastic is fairly brittle now and when rotating the case you should think through how the weight will be put on parts as you remove them and be careful. You will mostly likely damage the caps on the top screws removing them
