Have a PM1723C Sanwa V21 chassis and I keep finding more parts that need replacement. The flyback is cracked on the focus/screen block, and the solder joints to the legs are clearly bad. As with my searches for other parts for this chassis, finding a flyback has also turned up dry.

Flyback has part number MSH1FPU515A, GH22T, made by muRata. Looks to have the same body as a K7000 flyback (see picture for comparison shot.)

Anybody know where to get one of these or what the part crosses to?

Thanks

NOTE: appears file attachments don't want to work for me right now - will try to add the picture later.

Hi

Did you repair your chassis?
If so do you have a schematic?
I also have a Sanwa v21 pm1723c

I have changed all the electrolytic caps on the chassis to new one with the same value as the old one.
Only one cap i did not have in my parts boxes, main PSU cap where an 680uf 200V I put in a 470uf 200V.

It is now working, but I am unable to figure out why my image is shaking a bit.
See mu video here:

I have tried to find some schematic on the chassis, but no luck.
Does any know what can cause an image to shake?

I have not messured the B+, because I do not know what it is need to be.
