WG 19k4679 problem

[IronBuddha]

I recently bought a Dig Dug cabinet, after playing it I noticed minor problems with the picture. Occasionally the game would lightly flicker and when the bottom half of the game gets darker (level 9) it would be too dark, you couldn't see anywhere you were going. So I started making adjustments turning the knobs on the monitor figuring out what each one does because I have no experience at all with monitors. I went to turn the one knob, I barely touched it and it fell apart. Now my screen is all messed up and I'm not sure what to do about it. I took some pics hopefully they'll help!

Here's what the screen looks like now.


Here's the back of the monitor


Any help is always greatly appreciated!

That's called a "potentiometer" (or pot) and it needs to be replaced.

it looks like the plastic part just fell off....the metal wiper that does the electrical connection looks like it's still there.

you may be able to just use a small screwdriver to turn it slightly (you may have tweaked it when the plastic came off)

I tried adjusting it with a screwdriver but I can't get the picture back. I'll just try to replace it.



I can't seem to find anything on this model. If you google "wg 19 k4679" this thread is the only thing that shows up? Does parts for k4600 work for all models?

I found out the info I need to replace it, I need a 50k pot with the same leg spacing so right now I'll match it up and place an order with the real bob roberts.
