Tabasco reel touch top box power

(1/2) > >>

Phan000:
Picked up a project machine yesterday,

Top screen dark, “waiting on video” tilt on the bottom.


There were some “spare parts” inside the bottom.  Looks like the former owner knew the top box PSU was bad, and had started the conversion to a new PSU.

I’m not sure what supply was the original, or how a new supply is supposed to be mounted in the top box.

Would appreciate some direction to hopefully get this machine going.

qbert:
Power supplies are becoming tougher to find.
Your best option is to make one from an old computer ATX Power supply. They work equally as good and last longer. The original power supply mounted behind the top box using the mount you have pictured.
There is plenty of room behind the top box for the larger ATX converted ps.
Make sure you cut and use the smaller plug from the original ps.

Phan000:
Thanks Rich.

I replaced the power supply per directions in link.

Upper box PC is getting power,  fan on the processor working,  couple of led lights on.

No display still.  Bottom says waiting for video.

I tried connecting a monitor to the VGA out,  but no signal.

What is the next step?

qbert:
The bottom "waiting for video display " indicates the bottom of the machine is working properly. The top box is what must work now.
Open the top box, does it make are any beeps or chirps when powered up? Carefully reseat all of the plugs on the mpu board. Remove and reseat the two memory cards 4 or 5 times each to remove any corrosion.
Post some pictures of the top box motherboard.
It will eventually need a battery replacement but do not worry about that until we can get some signs of life from the top box.
At this point in order not to place undo stress on the bottom cpu I would unplug all of the cables going to the back of the top box except the two from the power supply that you made and just supply power to the new power supply for testing purposes until we get some action from the top box.
Depending on the bios type it should either chirp once and you should see some video action or chirp 4 times then see something on the screen. If it continually chirps reseat the memory cards again.
If it makes no noise at all it is not going into the boot sequence. Inspect the board are the ends of the capacitors bulged out. Take and post pictures.
If it is easier for you, you can remove the top box and work on it on a table or bench. It should swing out of the machine and simply lift it off the hinge pins.

Phan000:
I took. A few pictures last night. 

Looks like some of the caps are swollen.

No chirps or beeps, however when I manually turn off/on atx PSU, there is a slight chirp, but sounds like feedback rather than a firm chirp.

I will try to re-seat the ram sticks this evening.

Looking for possible replacement boards on eBay. 



Main board is strange-  guy left the varta battery on, but removed the coin battery.  So ram error must be cleared every time.
