Hey, I have a NEO GEO machine that I am restoring, and the monitor has a problem! THe focus starts clear as day but then as it stays on it gets more blurry as time goes. After a while it will snap back to being clear as day though and do it all over. The focus knob has no effect either, anyone know whats next? Any help would be awesome.
Thanks

And the make & model of the monitor is....??????
-
it is a 13" Wells-Gardener model # 19K4613 called wells gardener and they told me it was WGE1372-HOT582K
Thanks

Huh? ???
This is confusing. You say you have a 13" monitor yet you mention 19K4613. The 19k4613 is a 19" monitor of the 4600 series manufactured around 1981. That's well before Neo Geo games were invented.
This other model number you mention WGE1372 is a 13" of the K7200 series which is a currently manufactured model.
How about posting a picture of the chassis to clear up the confusion?

It is actually a Neo Geo Conversion. I found defender art under the current paint while restoring it. The monitor is 13" Top to bottom. Left to right is around 17? The second # is a number wells gardener gave me to get a replacement monitor for the one I currently have. Heres a few pics

Ah, now we are getting somewhere. You should have mentioned it was a conversion cabinet. I thought you were talking about a dedicated Neo Geo cab.
Your picture is definitely a Wells-Gardner 19K4600 series (19", horizontal mount). Check the neckboard for bad solder joints especially at the picture tube socket. Also look closely at the foil on the neckboard for CRACKS!
It's possible that the internal socket contacts of the picture tube socket on the neckboard may be corroded and if that's the case, then the socket must be replaced with a new one.
The main monitor board and the 3 plugin boards (power regulator, video interface, and hor/vert deflection XY) are also well known for bad solder joints.
It's possible your picture tube may have an intermittent internal short circuit. The best way to check/repair that would be put the picture tube on a restorer/analyzer (a.k.a. rejuvenator).

Im kind of new at this, but I think I understand! I'll check it tomorrow after work and let you know what it looks like. So Its looking like I may have to resolder some wires, but how would I get ahold of a "Rejuvinator"? Would it be cheaper to go ahead and keep going with this monitor, or replace it? And finally, if I did replace it, would the Wire harnesses be the same, or would I have to do that myself? Thanks a ton man, I truly appreciate the help.

before rejuvenating the tube and after you have checked the solder joints you should also replace the capacitors and see how the picture looks then--do a search on cap kit--or have a look in the FAQ for what I mean.
