Commodore Monitors by Model Number
Commodore 1802 monitor was released in 1986, it matches well the white-case Commodore C64G, C128 and C128D. There were two cover designs equipped with the same internals – first as in the above picture, second – probably older design similar to 1901 – as on the picture below.

When recapping, please pay attention to C806 near the back input panel. Its polarisation markings on the top and bottom of the PCB contradict each other. The correct polarisation is on the top of the PCB – plus facing the back of the monitor.
Reassembly
Cable Arrangements (and some dirt)
What a great, and bloody thorough resource you’ve provided. Fantastic. Just bought one of these at auction and the power switch and volume controls are working, but faulting. Most likely corrosion over time, but these photos really prepare me before opening her up. Thanks.

I am happy it can help you! The monitor is working flawlessly with my C64 so far.

Fantastic! I have one of these with the dodgy power switch and missing door. Any idea where to get a replacement door? Even 3D printed would do. The monitor is very yellow and has writing on top as it belonged to a school, so I’m looking forward to giving it a refresh! Thanks for all the info 🙂

It is rather impossible to buy a separate original cover door. They surface rarely and get auctioned at unreasonable prices. Maybe you can find a 3D model somewhere. It can be easier to buy a broken monitor with the cover. Good luck.
