Help and possible part needed?

[qbert]

In theory yes I have not tried the whole board. I know folks have taken parts (like that daughter board) and used them successfully.  Make sure you get one that has a bios chip socket so it can be changed out to the IGT bios chip as I'm not sure how to flash the soldered in type.

I have never seen the display work with the monitor that is there, all video for me has been external. First time he fired it up it went all white but was beeping bad ram so easy fix, now it is always “off” or black as there is too much ambient light for me to properly diagnose if it’s on black... one time since I picked it up about a week ago I saw the screen all white, and that was after about 4/5 hours of it just sitting there on.


So I am leaning towards bad power bad invertor bad screen? I will research boards today and see if that helps, but everything looks in place so it’s a head scratcher. Any opinions or suggestions are welcome!



My next move is to clone an image of the drive before I power it on again, just to have a save point sort to say, as the hard drive passed diagnostic runs, but also came up with the message “too many bad sectors to repair” on another program.


Qbert, as for the was the screen looks to send it in high quality I will be emailing you the image shortly.

Make sure the top box power supply is good. I had turned on a machine, had a constant beep beep beep , screen would not lite, turned out to be the power supply behind the top box.

[Samm329]

Ugh my message never posted I need to go to my computer to retype it again, but short and sweet I’ve never seen the internal monitor come on

[Samm329]

So I pulled the power supply, looked at it, by visual inspection it is ok, I can probably hook a computer power supply up to it in a little while and see if that helps it any. I took the video board off, cleaned it, as well as all the connections, the jumper had some build up on it so I cleaned it as well, put it all back together and still have the same, no display.


I will hook up a power supply tester once my business partner gets in today, as he is the one who typically does the pc repairs, and I focus on the apple stuff, so in turn I don't know where he keeps it, lol.


Still at this point, I believe it is something to do with a broken display, and something to do with bad power to it.


Thanks for all suggestions.

Your wasting your time if the computer board and the HD are  working the power supply is good.
Thanks for your update I did not realize the screen never worked. The high voltage board is suspect. It is located way on the edge wall looking all the way back on the opposite end where the top box opens.
What is your time worth, I'd be looking for a replacement top box and now you would have lots of extra spares.

Here is a link for making a power supply from an old ATX computer power supply.

The search is on for a new top box! I already messaged haywire just waiting to hear back. Time to get known working parts before this project can really go any further.

[Samm329]

So I get a new monitor go to hook it up and break it. Projects on hold now...

Let me take a guess.
Cooked the harness to the hardrive. Easy to do.

My guess... you dropped it on the bench and cracked the screen?

[Samm329]

I actually was going expert level, bought a screen on eBay that I could take apart and rebuild. And after spending a few hours getting it all set up, I broke one of the fluorescent bulbs I had made... so that was done.




Really I am in need of that little sub video board in my unit. I have deducted it down to that board as my backlights will work, but my display will not. So if it not that board the point of failure is on the motherboard...


Does anyone have that little yellow sub board for video laying around that they could sell me?


I reassembled the unit completely to its original state, but still need to hook an external monitor to it to calibrate the touch and then for the bonus round.


Thanks!

Check this board on fleaBay he also has this board without the bios socket for about 5 bucks cheaper that has the LCD driver board. But if I were you I would replace the whole motherboard and switch over the CPU/fan and the memory.
He ships super fast I had one in two days.

New board is eta for tomorrow. I’ll keep you posted.

[Samm329]

So I got the new board today. It was brand new not even used!


I went with replacing just the sub board first as it seemed to be a root of my problems, and voila the machine is up and running again! So I have a brand new motherboard if anyone ever needs.

[qbert]

Nice work, glad it's up and running.

Thanks for your help qbert!


I do have the image of the machine working so if you ever need the hard drive image I have it
