Hi Cruiselad,

What kind of problem are you having with the D9300's?  I've never worked on a 9300, so I just went to the Wells-Gardner site and downloaded the 9300 schematic...it look suspiciously like a Tovis model # MTG1971X...it looks like some of the components are different, but all of the waveforms are exactly the same.  I don't have much on Tovis either but it may help somewhat...

If the monitor(s) is(are) blacked out check items listed (under Tovis) in this post... http://newlifegames.net/techforum/index.php/topic,454.0.html

If the monitor has other problems, all I can suggest is to revert to basic troubleshooting techniques...
1.) Verify (that there is an actual problem).
2.) Visual (80% of problems can be found visually).
3.) Power (check for AC ripple with an o-scope)
4.) Divide & conquer (check for signal 1/2 way through circuit, if there go 1/2 way through the rest of ckt, etc...)
5.) Remove, replace, &/or repair (self-explanitory).
6.) Smoke test (Plug it in, turn it on, & look for glowing components).

Hope that some of this helps...good luck!

Hi Cruiselad,

I would have to agree, "give me a Ceronix any day", & that's only because I've repaired more of them, so that I'm more familier with their problem components then almost any other monitor...

Sorry, I wasn't of more help...you might try;   http://forums.delphiforums.com/slottech/start   there are many knowledgable technicians on that site and most are willing to share information.

Good luck,

I have found that the flybacks are faulty and trying to get a replacements part #053X0674-001. I can find them is at Happs and they are $84.80 each and from Wells Gardner they are $90.51. Any assistance would be appreciated

Quote "assistance would be appreciated" ....

Sounds like you are looking for a donation to fix your machine ??  Sorry I can't resist. It just rememinds me of a guy sitting on a street corner with a paper sign that reads "help please". Of course you would be leaning up against your video slot and use a casino coin bucket rather than a hat...ok I digress.....

Here are a couple places to check....
www.slotmonitorrepair.com
www.mcmelectronics.com www.mcminone.com (Japanese Semiconductors, Flybacks etc)

http://www.flyback.com/

I have also found that the micro processor goes faulty...... The cost of the flyback transformer and the micro, you can buy second hand monitors complete for almost the same price. The assistance I was after was where to buy the flyback from, as I'm in the Caribbean I just can't go down the road and look for parts.
