I’m having an issue with a Bios 1. I believe the issue is with the top box. The VFD is stuck at display passes self test. I previously had a msverify comm error. Top screen starts up to boot goes blank and sits like that.
So far I tried the following:
Remove and replaced memory sticks several times in the top box
Removed several wire connections and ribbon wires and insured they are seated properly
Reseated all I/O boards
Back of top box as led lights on and beeps when I turn it on
Was working last weekend when I powered it up yesterday it came up with errors Any assistance would be appreciated
-
I just tried connecting the keyboard to the top box and loaded optimized settings. Now it’s continually looping to the RFA boot screen and lower VFD says display passes self test
-
Cell coin battery voltage might of dropped too low.
-
I changed the top box battery. I continuously loop to boot screen and VFD stuck at display passes self test. Is it possible that the problem is with my MPU?
-
Ok let's try to sort a few things out.
Lets start with the top box, on the top box unplug the plug that has 3 or four gray wires. Start the machine and see if it will get past where you are now. It should boot all the way to the last screen that will say initializing...
Also when you turn it on for the above test please tell me what the VFD on the bottom says along the way.
Leave on for at least 10 minutes regarding the top box test.
The bottom should eventually give an ms comm error.
Bios 1 machines do not like to be turned off in mid boot so keep your power on and offs to a minimum.
Report back

Making sure it’s this one?
-
That is the correct one
-
When I first turned on the power I had nothing on the top screen. Turned it off and back on and the top monitor started boot system. VFD had waiting for video display. Top box did 3 boot cycles and VFD went to Msverify comm error. It still at that and nothing in the top box
-
Luckily I left it on. After 10 minutes got display passes self test and top screen is booted again.
-
That’s as far as it got. Same place I was before
-
Not sure what else to try?
-
Be patient...Qbert's your guy
He'll have an answer for ya. :yes:

Sorry went to a show with the wife.
Bottom box is OK top box may be starting to suffer.
If the harddrive went bad it would give you an error.
Was it working before you changed the battery or did you try changing the battery because you were having problems?
-
I tried changing the battery because it was not working.
-
That makes sense. Bios1 can function with a dead battery up top. Now for the bad news, the top box probably needs a new motherboard or at least the one you have recapped (and there are a lot of them).
I know you have other Reel Touch. If you have another bios1 top box you might want try this drive in this machine with a different top box to be sure.
These are getting really old and parts are hard to come by. I know Jim at midwest slots had a few working top boxes but expensive to ship to you.
-
Thanks for the assistance. I have 2 other reel touch machines but both are bios 2. Can I use the motherboard from a bios 2 in this machine?
-
No the harddrive is set up for bios 1
You will destroy the harddrive if you try that.
You can however take your bios 2 box first remove the bios 2 harddrive, then swap out the bios chip from the bios 1 top box, install the bios 1 bucks harddrive, install in Bucks, resave the optimized settings with the keyboard and give it a shot.
-
Not sure what one is the bios chip?
-
Do not pry on thechip socket it will crack.
Take a paper clip and bend the very end at a 90, then use it to hook under the chip and pull it up carefully.
-
Sorry for taking so long. I swapped it over to the other machine. Everything works perfectly. So that rules out MPU and Hard Drive issues. What is causing the issue?
-
I put the Bios2 in the non functioning unit and the top monitor is not displaying anything at all. Led lights are on the boards and the fan is working but nothing comes up on the screen. Hopefully that helps to pinpoint the issue?
-
Try reseating the memory but the bottom line is that top box motherboard is bad. Any beeps from the unit when you plug it in.
At this point the only possible chance is to try and recap it. This is a difficult job at best since the board is two sided with no guarantee that this will fix the problem.
-
Will try the memory sticks. A couple years ago I was able to buy a motherboard for the top box for $45 on eBay. I don’t see any on eBay. That’s not good
-
Unfortunately those ebay boards are long gone.
That would probably bring it back to life.
Might want to post a wtb to see if someone wants to part with one of those ebay boards.
-
Do you think I should swap top box motherboards to confirm?
-
Not sure the risk is worth the reward?
Remember the working box is just as old and fragile.
Most of the time aside from contacts on the ram memory the rest of the top box components are usually bullet proof.
You may want to swap memory to confirm they are good.
It was semi booting before when it was a bios 1 correct
No beeps when you power it up? Did you get the bios chip in correctly?
-
When I swapped the non working machine to the bios 2 I got no beeping at all. No video at all. Does that mean something?
-
Not to be a smart ass, it means it's broken.
Maybe the cpu under the fan, usually the only time those fry is if the cooling fan failed, but you said it was functioning.
If you pull the memory sticks out and try to power up it should start to beep. If it doesn't it's no longer attempting to boot. Again recap may fix this.
