Hi Rich. It depends what your problem is. If the inverter
board has gone but the tubes are ok, then you could get the inverter board repaired. If the tubes have gone, then there is no repair except to find used good tubes on eBay. BUT!!! This is what I did to fix it for a friend. Open the unit, and very carefully remove the light box from the LCD, but DO NOT separate the LCD assembly. Remove the broken tubes, and all the associated junk, and the inverter board. Buy a 12 V reel of LED lights
with a sticky back, and find the scissors marks and cut them to strips that will fit in the back of the box stuck against it. You must solder a parallel connection of wires to the solder points, leaving about 8" spare. The strip lighting
will not take a bend, it will become unstuck. Locate the cooling
fan, and the other unused cooling
fan socket that provides....YES, 12V !! and power the LEDs from that. The dimmer does not work
, obviously but, you will be able to see the screen again. If you want to get fancy, get one of those remote
control LEDs and you can change colours, dimmer, whatever you like.
