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.
Another equivalent design of the PCB:
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.
