Can anyone tell me what kind of monitor this is by these pics?  I haven't gotten around to taking the monitor out to fully inspect it but I don't see model number anywhere from the back of the cabinet.  It's a nice VGA monitor but it has a pincushing problem that I can't adjust and sometimes it jitters horizontally.  It expands and shrinks a little.  The horizontal adjustment on the remote board doesn't fully expand the picture.  If it's a difficult fix I would rather sell it.

Forgot to mention, this is a 25" monitor and the jittering is very random.

Any advice would be appreciated.

Are you sure that's a VGA monitor?  Looks like one of the monitors I pulled out of a Virtua Racing I busted up a month ago.

It's a Wells-Gardner, probably one of the "U" series.

Virtua Racing (as an example given by Peale) used a medium resolution monitor.
The Wells Gardner K8000 seemed to be the most common found in them.

That seperate power supply board in the last pic kinda gives it away also as being a WG K8000.

I'd recommend the usual capacitor kit, re-soldering of joints, checking for bad/loose connections between the power supply board and the chassis.

i have seen one of these in a konami gti club,it looks like an updated u5000

[Kevin Mullins]

Hmmmm..... I just pulled that old K8000 I had stashed in a box of parts and it is similar, but defineately not the same main chassis.
The power supply board is the exact same one though. (that's why I assumed it to be a K8000)

EDIT: The Wells Gardner site has that power supply board (P756) listed for a 3000 series.
P756 POWER SUPPLY       27K3003       WGM2730-U0TS55F       
P756 POWER SUPPLY      33K3001      WGM3330-U0GS52F            
P756 POWER SUPPLY      33K3201      WGM3331-U0TS59G
P756 POWER SUPPLY       33K3301       WGM3332-U0TS65G            
(maybe I have the wrong board for this one I have) 

[Kevin Mullins]

Can you find a Pxxx number on the main (larger) board? Like P767 or P754?

[albert_c]

It's a WGM2730 U3000 Series monitor. 

Unfortunately it died all together.  Now all I heard is a clicking sound.  I found a guy who repairs them online for 100.00.

Not sure if it's worth it though.  The monitor had nice sharp colors before it died aside from the problems I mentioned earlier. 

Any suggestions on where I should go from here?  I screw up every monitor I touch.  I would rather not work on this myself.

ticking=power supply unstable and not starting
due one of the following;
bad solder joints
poor cable connection
faulty horizontal deflection transistor
faulty flyback transformer
faulty or leaking electrolitic caps in power supply circuit
faulty high voltage polypropylene cap on hdt circuit
plus a number of less obvious problems like o/c resistor/diode or voltage regulator
bit of a job i'm afraid if you're not that familiar with monitors

[modessitt]

First, do the replace of every electrolytic cap in the power supply section.  When the most recent "ticking" monitor came across my bench, I followed the flowcharts and maintenance guides and checked transistors, diodes, resistors, etc. and replacing the caps in the PS circuit fixed it.  If you hear the clicking slow down then stop when it's shut off, instead of stopping immediately, I would bet this is your problem.

But check the stuff GrantSpain mentioned while it's out to save time....
