Title: Monitor stuffed, now I need to re-plan
Post by: bigtrev2 on June 17, 2012, 04:43:31 am

I have an old arcade upright which I've been slowly MAMEING over the last 18 months or so

    I got the arcade monitor repaired ages ago..
      Acquired a JAMA harness adapter & ArcadeVGA from ultimarc,
      rebuilt the control panel (with help!) to emulate Doc's Modular Mame console.

    Today I've spent the afternoon wiring up the control panel and slotted in the arcade monitor.  With a few minutes more work I could plan some games with the PC sitting out the back of the arcade unit.

    That's when I noticed that somehow over the last 12 months or so, the yoke has been broken. 
        SCRATCH one arcade monitor  :hissy:

      So now I've got to replace the monitor.    I don't know easy it will be to find a reasonably price arcade monitor
   The other option I suppose is to use a LCD panel, and get rid of my ArcadeVGA, raster based light guns and decide whether to strip out the current wiring harness and completely re-wire the internals, which would mean that I could make heaps more room internally for the PC, or keep the current wiring harness and use the JAMA interface (I've got an IPac2 somewhere....)

   Oh well, looks like my MAME project got put back onto the back burner. Again....


   Any thoughts about stripping out the harness?  Or places to try for a decent Arcade monitor????  I'm in Adelaide....

Start taking apart old TV sets with the same size tube until you find one that you can swap in.

Thanks for the tip!

    I've also since found Jomac.net.au.

      I know absolutely nothing about TVs, and have deliberately steered clear of dismantling them before.  I've shocked myself too many times to count on mains stuff in the past and have a healthy respect for EHT - hence my lack of desire to go delving inside the beast!

      Guess I'll have to bust that cherry now, and start looking for TVs with the right sized tube.  I may just go down the replacement chassis + tube option as I'm clueless about how to match up a tube.  As I understand it you have to match up the deflection coils and yoke pins somehow, let along what needs to be done to get the picture to display properly...

      Anyway I'll see what comes up tube wise and make up my mind then....

There are websites that will explain the tube swap in detail. It isn't that difficult.

Also, arcade collecting FAQ docs tend to overemphasize the dangers of working on monitors. All you need to do is build a basic discharge tool and use it as directed.
