I have a Commodore 1942 monitor that started developing a problem where the screen would go black and would need a slap on the side. Then the screen started to get all washed out. Now it needs a slap and the screen is all washed out. Need somoene local that can repair it. Took it to a local TV shop and they failed to fix it and charged me anyways. I am in the Tacoma area, let me know if someone can help.
i use about 4- 1942 monitors they all had the same bad solder joints on the board. resolder the flyback transformer,and all the chokes,if in doubt resolder any other joints that may look bad. they have been working for many years since then without a problem.
the sad thing is they are fixable when they start glitching, but people run them forever with known problems and sometimes that kills the flyback or some other part since the resistance in the solder joints can cause heat. slapping them is the best way to screw up the tube.
i got a poor 1960 from a guy who ran it till it completely burned up a transistor inside into dust and burned a 1/4" hole through the board. All preventable if he had just stopped smacking it and opened it up to fix the bad solder joint lol.
As robert said, ray carlsen is the man.
