Monitors
Commodore: 1960
Connection: DB15, DB9 |
The 1960 may have been made by Daewoo (Korea) or a Taiwan company, or may be an OEMed Panasonic Panasync. The tube is made by Hitachi. There has been some debate over whether it is a true multisync or a trisync monitor. Reports have been provided that indicate it can handle Super72 screen modes at about 23 kHz, and the manual says it can sync up to 38 kHz. It may be a sort of hybrid, with a wide "window" in the 15.75 kHz to 31.5 kHz range.
Common Problems
One common problem involves a component that is insulated with eletrical tape (inadequately) from the factory, resulting in arcing. Replacing this insulation can cure the problem.
Typical failures also result from cold solder joints on the 1960 boards, which can be repaired by resoldering. Additionally, some solder joints (such as those on the flyback transformer) tend to go bad with age. Resoldering them may cure arcing problems.
The screen size adjustment pots may be prone to failure, making adjustments difficult.
