Uniwell TX-870 Screen freeze

Postby djstuw on Thu May 04, 2017 11:50 am

Hi guys, I'm new here and looking to see if i can get any help.

i have recently had 2 of my tills do strange things.
one of the tills screen has just frozen on a page and i cant get off of it no matter what i try, i have even tried the reset and that didnt work.
the other till is similar however this one freezes once you press a button.
i can get the till out of the freeze by doing a reset but then once i login with the key fob and press a button it will instantly freeze again.
does anyone have any idea whats going on? have i done something by mistake that i was unaware of?

Thanks in advance

Are they linked? If one is totally frozen and they're IRC'd then it could quite easily lock the other one up as it tries accessing the frozen one.

they were all linked, however i have taken the frozen ones off and playing with them stand alone atm.

something i have just noticed with the one that isnt locked completely is that when i reset it all key buttons work except when i press a PLU key for example a pint of coke. then it freezes.

if i was to press price level and then change the levels etc that all works fine, its almost like its lost the prices or something.

Have you re-initialised the IRC network since you disconnected the tills?

The first step is to take the till fully off, turn S key to 'BLIND' position (past Z1/P).

Perform an Initial Reset and calibrate the screen (A, then B). Note, to perform Initial Reset: >Turn power switch to off, >Turn power switch to on, >As soon as the blue light comes on, touch bottom left of screen, then touch top right of screen (must be in quick succession, and before the green A+B screen comes up).

If you hear four successive bleeps, you have succeeded. If not, try again, it requires the correct timing.

That should clear down anything that is locked up and let you recalibrate the touch-screen as well. Once that's done turn the key back to Reg and see if it's responding.

To initialise the IRC, turn the key to Z1/P, enter your manager code, 8800 ENTER and it'll do what's needed.

Thank you S1mon, with a bit of trial and error i have managed to find the INITIALISE IRC by turning the S key to SP, putting my keyfob on then selecting IRC PROG FUNC, then SP-8800 INITIALISE IRC

i ran it and it has brought my till back to normal and working again :-)

now, my problem with the other till is that i cannot do a reset on it as it just wont let me the screen is frozen completely.

Even if the screen is completely frozen then you should be able to do a full reset as described.

If it's not responding when you press the screen as described, then you may have something jammed in the edge of the screen - they only accept a press in one point at a time, so a grain of salt or sugar stuck in the edge can completely screw them up. Try working a soft brush into all edges, especially the bottom two corners, to see if that frees it up.
