Rdsellers54, Can you see very faint image on the lcd panel if you shine a very bright flashlight 1 inch from the panel at different angles? Yes = 5v dc supply ok, lcd 12v dc not ok. No = 5v dc and 12 vdc not ok. You or technician will need to check units "switch-mode-power-supply / CCFL power supply dc rails first. This display no different than any other cold cathode fluorescent lamp back-lit lcd monitor on the market today. May be of interest for you to see some video clips of lcd monitor SMPS being repaired at YOUTUBE by their owners/technicians and noting the main culprits responsible for "black screen of death" symptom!! Then do some rading of FIXYA profiles of "budmrtn" and only the higher numbered profile pages in my profile. 12fixlouie

Reciept side ink not printing


Need a new ink cartridge. Just like any printer they do not last forever before it needs changing and faded ink is classic sign that is the case. Skipped spots but good darkness would indicate some thing is dirty instead but that is not your situation.

Screen on JTX V 5 monitor has gone so dark I can not see anything. Besides it flickers on and off in the dark .


The back light is failing, and possibly the power capacitors for the HT circuit are failing to store the voltage necessary to power the screen, which would explain the flickering. This needs tested by an expert in monitors and TV's to confirm the actual source of the issue

Cash drawer would not open, register error!


Usually there is a pull on the bottom of the register to open them. Try to find it to open the register and remove the book.
