You can get a whole new display for about 150 on Ebay. I don't think it is your display. I think it is either the power supply or mainboard. If you lay the display face down and remove all the screws aroung the edge the case will open into two halves. The display board is mounted to one half and you will see the main board in the other half. The power supply sits under the main board. There are like 4 screws that hold the main board in and it will lift
out. All of the board are connected by a few ribbon cables
thst unplug from a socket. The displays are usually good. Mainboard and power supples are what tends to fail. If your near Mobile, AL I will give you a power supply board. I do not currently have a good spare main board. When you put the case back together put some silicon( not the glue kind) on the rubber gasket
and do not over tighten the screws. CAELESTIS
had a display foe sale
. PM him and see if he still has it.
