LCD backlight problems
Hi,
Got a KOGI L4BX monitor with a picture and no backlight. Can I simply use a
VOM to test the output from the inverter? Is it typically worth replacing
the bulbs? The inverters seem to be about half the cost of the unit so
replacement of that part isn't really financially purdent (or is it?).
Thanks for any help!
