UNIWELL NX-5400. Key pad not responding at all. Initially had some digits stuck on the display , 5 on the left end of the screen and 10.00 on the right side of the screen. Screen has now completely gone off-completely dead. Transformer,fuses are all good- Is there a specific part that would cause the display to go off and key pad to be non-responsive?
To reset the cash register, turn the plug off at the wall, then hold keys 3, 8 & 13 (Not on the number pad on the right, but all the way to the left, 3rd key from the top and the 2 buttons next to it).
WHILE holding those numbers switch the plug back on. The register should now be reset .
