What does this look like to you? K4600.

I recently bought a Wizard of Wor converted to Yie Ar Kung-Fu and it came with an installed K4600 horizontal monitor and two vertical mount spares, one of which is another K4600.

The monitor in the machine works and the colors are correct, it probably could use caps but the screen is burned really bad.

The spare monitor is in a vertical bracket and the screen has no burn at all. I connected it to the game last night and took these pics.

My question is twofold.
#1 since these are both K4600's I should be able to swap the unburned tube into the working bracket and chassis, right?

#2 The chassis on the monitor shown in the pics is much much cleaner and the boards look much newer than the one installed in the machine. The serial number on the newer one is 50,000 numbers higher than the older burned one. Do the off colors look to be something that can be corrected by me, an electronics layperson with a cap kit and some adjustments? If so I was going to use the good tube and its matching chassis when I rebuild the machine. If not then I will combine the good tube and working chassis to make one good monitor.

Please advise.
Thanks,
Brian

Hmmm, those green diagonal lines look really familiar. :)

See this thread, where myself and another member had the same problem: http://forums.arcade-museum.com/showthread.php?p=931387#post931387

In my case, the "green" input signal to my monitor was floating, due to a bad connection at the game board edge connector.

And yes, I'm pretty sure you can swap the tube, but hopefully a more experienced member can chime in with a definite answer.

Hey Delroy thanks for that, I read the whole post. I don't get the green tint to the screen when the game board is plugged in to the old burned monitor so I'm guessing the problem lies with either the new tube or something wrong on the new chassis.

I guess I should swap the new tube into the working chassis to see if I have a bad tube before I go much further.

Is tube failure common?
 
looks like your SCREEN ("brightness" knob on the flyback,) and probably your GREEN DRIVE are both turned up too high.

hard to see if there's any red in those pictures as well

Thanks MC, I'll check that out.
 
Very familiar indeed... if you manage to track down what is causing this, please let us know. I've not been able to track it down, myself. My solution is soon going to be "get a new monitor." ;) Screen and green drive adjustments did nothing for my issues.
 
OK I just went out to the garage and ran both 4600's on the same game, both are displaying the same image as I posted in the pics. When I picked up the game the image was correctly colored with the installed monitor. Obviously something went wrong during the move since now both show the same picture. I'm going to assume at this point that the newer, unburned monitor and chassis are probably the best bet for the recap job and there won't be any guessing as to it working properly with the other chassis.

I'm going to clean and recap the newer monitor's chassis and them swap that chassis and tube into the horizontal frame. The older monitor chassis although it works, is making a pretty angry sounding hiss.



Now to start saving for a JROK multi Williams board.

Thanks for all the responses and help.
