Title: Anyone on here in the Seattle area that can repair monitors?
Post by: TjLaZer on September 01, 2015, 04:15:44 AM
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've got a CEI 1962 with the same symptoms, so I wonder if this is a somewhat common occurrence with older CRTs. My family had a 1970s Toshiba television that also died in somewhat similar fashion.

Is there a more competent TV repair place within driving distance?

I too, have a 1942 that went bad.
First the on/off switch wouldn't stay on, so I used a power director.
Then the power supply died.

The local place (in Sacramento) I went to told me they couldn't get parts.
but didn't charge me anything.

Anyone out there in Amiga world want to setup a repair shop? (lots of work)

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.

That is odd, since the power supply is made up of mostly common generic parts. the flyback may be the only thing hard to get. Most the shops out there are poor troubleshooters and are scared to do anything without a schematic. Bring a schematic with you if you can find it will often make them more likely to take the job on.
