Title: Help Identify a monitor/Chassis Rebuild?
Post by: rawbe on February 12, 2019, 06:43:20 pm

Two monitors with two different problems.


#1 Makvision 3M25 monitor, with 25'' Chassis Model: C3125B.
No picture, makes clicking sound when powered on, no picture at all. At least one cap is busted on the chassis.  Does anyone repair this type of chassis or have one for sale?

#2 Not 100% sure the monitor model, it has 9A2988-1 Sanyo Mex 9649 on the neck.  Nintendo cab, Cruis'n World game.   
Need some help identifying the monitor model (possibly Sanyo EZ, Med res?), also needs a chassis rebuild.  Any help is much appreciated. 

Thanks!

The double anode lead points to a Zenith version of the K7000 (aka K7000A). Take a picture of the chassis to confirm.

i don't thinks its a k7000a, although it looks like zenith built( which it could be due to the double anode) if you look at the neck card it looks to be something like a k7500. It will be medium res if on a cruisin machine.

the other chassis is a rebadged weiya 3215 tri sync, not 100% sure but nieman displays sold a very similar chassis and could probably repair this

The neckboard is definitely not a K7000A one (neither 19" nor 25"). It does look like the U5000/2000/7400/7500 type. The double anode lead is unexpected on those though.

Out of interest, how does the double anode work? Like the Sony/Barco sets with their HV feedback to adjust convergence?
