Commodore Monitor Model 1801
This monitor is the PAL predecessor to the Commodore 1802. It appears to be a contemporary of the CM-141 and the brown-casing 1802. They both have dual inputs (Composite video/audio, and chroma/luma/audio) with a switch in front to select between them.
The Monitor although in excellent condition don’t work correctly, the image displayed was in black and white.
The problem was the oxidation of a little trimmer (see photo / orange trimmer) and it was enough to turn it a bit and put it back in its original position.
Other small defects fixed:
- Bad geometry – Calibration of the Deflection yoke.
- Out of Focus – Calibration Trimmer Focus on Flyback.
- V-HOLD fine adjustment on the Monitor PCB.
- Glued a piece of plastic broken at the base of the monitor.
