Wells Gardner Monitor Help Needed

[joshvandam]

I have a Wells Gardner D9200 - 27" Monitor. The monitor went black the other day except for a 1" vertical line in the middle. The line appears to be trying to display the picture. Does anyone know the fix for this? Do I just need a cap kit or is this problem caused by something else?

HOT (horizontal output transistor) ?

Sounds like deflection failure, could be a hot, (most likely not caps) bad solder connection etc etc ....
If you are near chicago i might be able to take a look at it, If its a med res monitor i may be interested in buying it as-is.

You're gonna want to check all the items listed in the "no horizontal scan" section of the post listed above. Make sure you check all of them because this is usually a chain failure that one bad part will take out the rest of the parts. The 9200 is a little difficult to troubleshoot depending on your experience. You might consider sending it off for repair.

Do the cap kit first, as that can sometimes cause this issue. Then use the troubleshooting sheet.

Trust me. I spend an inordinate amount of time with a D9200 in HV shutdown and went through all the listed parts, before deciding to just change the caps and that's what fixed it...

Due respect, what you experienced was a very different problem;

Just my 2 pennies, but...

It takes only a few minutes to check the semis in a chassis versus 45 minutes to over an hour for a cap kit. Most people can test semis and resistors, but not caps (at least not to the point of looking at the charge curves).

A total failure of a subsection points to a few parts that can be verified rather quickly with a good ol' VOM. Then you can evaluate if you need a cap kit.

And then, yes, a cap kit can address those questionable problems when the solution seems elusive. But just doing a cap kit to start off with only to find out that your HOT is shorted, or yoke is open seems like a setup for disappointment.

Due respect, but my experience with all monitor types led to my recommendation, not just because I fixed one specific monitor of the same type.

The D9200 is no longer a "new" monitor, and with the "lowest bidder" caps Wells-Gardner has been using to build monitors for the last 5-10 years now, it's likely they need to be replaced anyway. While you have the chassis out, you might as well do them while you're checking the other parts.

It's not just a waste of time, as it probably needs to be done soon anyway. Might as well do it now, while you have the chassis out, rather than fix one part now, then need to fix it again 6 months down the road.

Bad caps can cause deflection failure, color loss, HV shutdown, etc. By all means, check your other stuff, too, but if for no other reason, the preventative maintenance aspect of doing the caps makes it worthwhile in the long run. Besides, D9200 already has a bad rep, so any "upgrading" you can do will be beneficial...

Try q413, IC 404, r462, d424, q414, r415 (might be open)zd 403, r854..

These were not made very well your really better off dumping it and getting something else.

I really appreciate all the help with this one. I am in central IL. Does anyone know of anywhere in the area that could repair this?

The only two options I have seen from searching is HAPP or American Vending Sales Inc but both locations are around 3 hours away.

Personally if it were me and hearing what Chad just said - I think I'd listen and dump it.

 

[modessitt]

I got one, and after I fixed the initial problems, it's been working fine...

He has repaired several chassis for me and has fair pricing for all the time/effort he has to put in as well as reasonable turnaround times.

If hes saying dump it then you know its a bastage...
