Video Problem on my PE Poker with a 1492 Ceronix Chassis

[Amechanic]

I'm having a problem getting a good working 1492 Ceronix in my PE...  I have one Ceronix chassis thats dead, not getting the 12V.. I've changed out the caps, but that's has not helped..

I have a second 1492 Ceronix chassis that has it's 12V, and you hear the CRT energize, and the guns in the neck are glowing... The problem is I don't get a picture for almost 3 minutes, and when is done come on I have a split screen top to bottom? After about 30 or seconds the screens starts to roll.. Then and now it's almost 4 minutes since being powered on I have a beautiful picture... This chassis has all new caps except for the 3 large ones, and they test good with my cap tester.. I have replaced the Vertical power amp #192, and the PRA "H" board with not help? I'm not sure what to check next other then changing the 3 large cap and the Flyback?

Does anyone here have any knowledge on repair the 1492 Ceronix.. I know I can send it in, but I'm hoping to learn how they work and where the check for voltages..

Thanks, Gary

I'm not a monitor expert at all.  In fact, CRTs scare me. 

I'm moving this topic to the monitor repair section, since the issue is with the monitor and not with the particular machine (the IGT PE) that it's installed in.


Additionally, a quick Google search yielded a couple of items that may interest you:

Thanks Knagl for the Google search information.. I've replaced everything except the Flyback and the #280
XRC5184 ic, 16 pin IC.. I have both, so time to do a little more testing.

Thanks Gary

i have had 20 ceronix chassis repaired by ceronix in the past few months - they charge $65 plus shipping - the usual repair is 2 ICs and the Flyback.

Do you have the part number of the IC's that were replaced, and maybe the location number on the board? I'm thinging it #280, that's right in front of the flyback. It's a custom P.C. IC

sorry do not have that info - I thought I posted it awhile back - will look thru my paperwork.

Well I went back and found your ad on your Ceronix problem and repair.. Come to find out my problem was the LA7851 Horiz. & Vert. Control IC #218 on the 1492 chassis.. After replacing it my Ceronix chassis now works great and the CRT/Monitor fires right up in 6-8 seconds with a bright clear picture..

Problem & case solved...

PS.. While I was working on the chassis I did do a complete re-cap, except for the 3 large caps.
