I had the same problem with mine. It is caused by a crimped wire on the internal harness inside the machine. I opened it up and discovered that when originally put together 3 of the wires from the plug were crimped. One was broken off. The only way to fix it is to open it up, restrip the wires place a piece shrink wrap on before you solder it back and then make the shrink wrap flush with the back of the plug and heat her up. And, Voila... no more intermittent operation. Hope this helps? John

Backlight problem: Remove the display, remove the light tube from behind the LCD. Buy a led panel from Ebay for around $5 and install it behind the LCD under the drfusing layers. Run the wires out to a 12 VDC source and there you have it.
