PE+ CRT to LCD conversion

[azgamingslots]

just out of curiosity,  has anyone ever tried converting a sigma b-50 video poker to flat screen?,  seems like you run into screen problems, is it possibly vga instead of rgb?

[nousmeme]

After analyzing the info presented, it seems it would be a lot easier to just replace the original chip (74HC574) with a 74HC564.  It is a pin compatible chip with a built in inverter.  It should mount in the same hole and be low profile.

Ooh, that sounds even better.    Got one of those laying around?

Also, nousmeme, can you share with us how you have the sync hooked up to your CGA > VGA converter card, please?  Thank you in advance!

Using the ACV-011 from weyia.com.tw seems to be easier
Would you please take a look at the attached file?

That board is more expensive and seemingly harder to find when compared to the GBS-8220 and similar, but thank you for your suggestion and documentation.

I read thru this thread and can't remember if I saw this listed.

For $89.00 US, I think it would be a less expensive alternative don't you think?

It says they will be "Restocked" again Dec. 17th.

Hello....and greetings to all....
my dear friend nousmeme....I reviewed your pdf regarding crt to lcd conversion and looks nice but I would like to have also images of the converted machine working, in order to see if colors remain similar to those on crt monitors or if they look better. Not that I don't trust your post or mod...I tell you looks interesting...but would like to see that working.....is a nice option....

by the way if you have any interest I can offer you this interface in the photo at a reasonable price plus shipping. Works really good and is tested.

My dear friend nousmeme my respects....looks awesome...great job...

one doubt....you say on your document "It will require unsoldering a chip on the board (the video latch) and replacing it with a socket and a 74HC564" so I desolder or unsolder however you say it hehehe and put that socket?? inside that socket place 74HC564??? do these IC change in pin number??? or can I just put one in the place of the other?? sorry for my ignorance.

As for the friends asking me how to connect the cga/vga board I am offering. I leave you a picture with "connections"...on the IGT board.

hi to all from new zealand, i have just purchaced a jokers wild igt poker machine , it appears to a have a monitor issue, after not being able to convert the cga signal with a gbs 8200 converter that i  would normally use for arcade monitor testing/modifications , i have searched the internet to  end up here. the gbs 8200 & other versions are also available through allixpress, the red version of the cga to vga converter is better quality, the wei-ya cga to vga convertor is multi synch & a freq converter, where can you get the 74hc564 chip from?, has anyone else tried this yet? cheers matt

I have been watching the progress with this thread from almost the start and just wanted to thank all that worked on making this conversion possible especially PowderMaker.

I was given the upright PE+ Multi Poker machine and have been sitting on it for at least three years wanting to convert it to a LCD display. The CRT display was burned in, I had done the cap replacement so my final diagnosis was a failing flyback transformer and although it could be repaired I felt it was best to make the conversion.

I ordered all my parts from Mouser and the GBS-8200 off of eBay and began my trial run. I have to say it went fairly smoothly requiring only minor adjustments and I hope the colors are correct. Does any one have any suggestions on getting the service manual so I can learn more about these machines?

Thanks again to all!

Colors look bang on to me.
Which manual are you looking for ?
There is a PE electronic repair manual and there is a certonix manual specifically gor the monitor.

Hi Jay,

Thanks for the quick response! I am looking for any and everything for this machine that would cover schematics, error codes, trouble shooting, diagnostics because this is my first machine and really have no clue about it.

My background is in electronics and computer repair including component level and this project has sparked an interest in learning more about this industry.

Hi Buzz,

Thanks so much! As a new member it never dawned on me there would be a download section because I am used to having to buy the technical data when needed.

This place is a wealth of information and I’m finding myself spending more time each day exploring.

Thanks again!

I think it's all documented here in the thread, but it's been so long since I've looked into this.  Would you mind posting a couple of close-up pictures of your connections to the breadboard and the GBS-8200?  That'd be awesome.

Hi knagl,

I spent some time drawing up a wiring diagram and this should make it easier but I will still post some photos if need be.

KelTeck-

That's fantastic, thank you for taking the time to do that!  K+ to you.

Hi knagl,

You are more than welcome and it is the least I could do to provide to this thread to say thanks to you and all that contributed to make this conversion possible. Without any knowledge about these machines and without the info provided here I would have thought this would have been a straight change over.

I have not done any technical writing or drawings since the eighties and although I went over this drawing numerous times before posting I would like to hear if there are any issues that need to be resolved.

To get a little off topic, I would like to know if this field is something I should pursue since I am watching the death rattle of the consumer repair side for electronics and computers. If I should make a separate post for this let me know and I do not know what K+ means but I will do a search for an answer.

Thanks!

K+ is "Karma +" -- the silly little "Total Karma Storms:" thing next to your name.  If someone contributes a good post to the discussion, it's customary to give them a positive karma point.  The points really don't mean anything other than "thanks".  Once you reach 10 posts you'll be able to give karma points to other members -- I think right now you can only see the point totals, but can't do anything to manipulate them.
