I just went to the second site you mentioned...I just assumed the cost was in the hundreds if not thousands of dollars...Dude...if the company you work for can't afford $24.00 you NEED to find another employer!!!

If the program would make my life (work) easier, I'd purchase it myself and let the boss know that when I left the program would be leaving with me...

A little FYI...

I've been having problems with a couple bartop monitors (Ceronix 1493s).  I couldn't get the raster adjusted in the center of the screen, there was a gap about 1 1/2" to 2" wide on the right side that was blank.

I tried everything that looked like it would have an effect on the horizontal position on the schematic next to no luck at all (tried substituting some resistors and accomplished moving the raster farther to the left).

I finally took my problem to the techs on Delphi Forums and got the answer to my problem two small electrolytic capacitors at positions 344 & 347 had evidently dried out...thanks to dickcet & OkieMike on that site for the information...

Delphi Forums is another excellent source of information!

God bless,
Mike><>

I'm not sure, but I might have posted this previously...
I got a Kortek monitor that had compressed vertical signal...the top half of the raster had collapsed, the bottom half looked normal.  Turns out that C119 and C122 were the problem in the circuit...electrolytics tend to dry out after a while...

In the past few months I come across some problem monitors...the monitors worked fine on the IGT 960 test station, but on the floor the monitors wouldn't power-up.

Thanks to MBTECH3 for the heads up on the repair for this Kortek monitor fix...this is from delphiforums;
http://forums.delphiforums.com/n/mb/message.asp?webtag=slottech&msg=5990.1
"I had seen alot of those on the 17" which I had alot more of, now we are all LCD. The fix for that was C107 47uf@50v. I believe the tester kicks out around 220v AC for monitor power which is not  affected by a broken down C107. On the floor the games are only putting out 110v AC for monitor power which is affected by a bad cap in the power up circuit. As best I can remember."

This has helped me repair monitors that had me wondering about the floor techs...

God bless,

Just a FYI...

A  Ceronix LCD Inverter Board (P/N CPM2243) can substitute for a Kortek LCD 17"/19" Inverter Board (GH059A).

We've had a Ceronix Inverter Bd in a Kortek LCD Monitor for over two months and thus far it has functioned flawlessly.

Good Luck & God bless,

Hi king13,

I hate to appear ignorant, but I have no idea what a "p42sx pdp" is...

Is it a CRT or a LCD?  If it is a LCD the green light may indicate that the A-D board is receiving every signal that it is "looking" for (Horz. sync, Vert. sync, frequency, etc...), if this is the case, you probably have a faulty inverter board.

Sorry, I'm not of more help...

God bless,
Mike><>

Hello,

Do you guys have any information for any other model of Kristel, Kortek, Ceronix or Wells Gardner monitors?  I have done some work myself on boards of these monitors, and found faulty parts, but no schematic of BOM for values of the parts for replacement.  Your help would be greatly appreciated.
