you are actually right there is a *perfect* faint display this is readable
using the flashlight method you mentioned.
so now is the problem worse or better?? Am I looking at replacing a ribbon
cable or soldering power leads etc..
with the display being so faint / dark it would most likely be both of these
power leads to the inverter,
or the power supply itself.
