Richard, I need some more information from you please...
When you say all lights, I assume you mean where the numbers would normally be displayed, is that correct?
Also, when you say dashes, if they are where the numbers would normally be displayed, are the dashes in the top bar, center bar, or lower bar of the number?
I am still making further enquiries with the tech dept.Although the fault you have normally indicates a fatal error with the Touch Control pcb, in that it has lost its calibration.. in certain circumstances there is something that may be done to correct this. This is what I am trying to find out for you.Thank you for being patient
