monitor identification (solved)
« on: October 24, 2006, 05:36:30 pm »
The chassis has the following number screened on the bottom:  JVC  S75-94V-0, and on the top (near the 115V input) SU-11

The monitor has the following numbers: E419D-R4 and Model#11354.  Any links to flowcharts/schematics would be greatly appreciated.

I've also included a screenshot of what is wrong with the monitor (the image is fixed...not rolling), any suggestions appreciated.

You have a common Electrohome G07. Pictures of it are on Bob Roberts' monitor id page. Didn't you try there first? That should have been the first place for you to look in identifying a monitor.

Oops. Sorry about that  :dizzy:  I didn't realize Bob Roberts had pictures up (and yes I did read the FAQ in this forum, just a long time ago and I forgot).

So I'm assuming it's time for a cap kit based on what the image looks like. Is this what you guys call "jail bars"?

OK, just finished replacing the caps, still get the same "double image". Anyone have any suggestions?

It's a stable image, I know the game board works, and that the syncs are hooked up properly, as shown:



...with H and V joined together. The game board is a neo geo MVS, which is negative composite sync. I also had the exact same problem when I hooked up a Jamma game (which also was neg comp sync), so I'm pretty sure the problem has to do with the monitor.

I haven't loosened off the yoke, or played with the purity settings. This isn't a purity thing is it?

Did you replace the caps underneath the metal shield? If so, did you also put the metal shield back in place and resolder it?

Have you tried adjusting (very carefully) the horizontal hold, vertical hold, vertical size (height), and vertical linearity?

The problem shown in your screen shots is definitely not a yoke or ring problem so leave those alone.

hey Ken,

yup i replaced the caps under the shield, and put the shield back on.

I'll play again with the knobs.

One other thing... i noticed that there are 2 plugs marked "E" on the neck board, and the bottom plug is hooked to the Tube GND (diagonal wire on back of tube). The top "E" plug has nothing attached to it. Is this correct?

FIXED!!!

Geesh....i just turned the vertical hold and got it! After doing an entire cap kit!

 :dizzy: :dizzy: :dizzy: :dizzy:

Thanks so much Ken. Sometimes it's the easy things eh?

So if someone could tell me where the proper "E" post is on the neck PCB for the ground wire, that would be splendid!

Both of those E posts are ground connections. The yellow ground wire from the tube can be plugged into either one of them.

Thanks again. I feel like such a dork on this one. I DID play with the vertical hold before, but I must not have got the right combination of settings.

Considering I got the whole cabinet for $40, since the previous owner figured a major overhaul was necessary, I got quite a deal.

And now that it's freshly capped, hopefully it'll stay working for another 20 years!
