I have a sanyo drw-500 and recently the display light started flickering then just didnt work at all. it started when i turned it on and the loading display started flickering really bad then it went out all together, but only when i play a movie or record, the clock works but then it will start flickering. i unplug it and all seems to work fine for a few minutes then it starts all over again. it still records fine but no display on the machine. any thoughts on this.

If you're running it to the battery post directly its creating a strain-you'll need a power distribution block. Also consider a bigger body ground wire/cable. If this doesn't help, you will need a capacitor.
When it flickers, can you still see the text when the screen goes dark? May have to use a bright flashlight set right on the display to see the text on the screen beside where the light sits. That will tell you if it's the backlight.
You can also look at a grazing angle into one of the edges to see if the backlight is flickering when the display does. When it's cold, does it start with a slight pinkish color? That can be a sign of backlight going bad. Anything interesting happen when you flex the cable by moving the screen?
I'm not saying it's impossible, but I've never seen software cause consistent screen flicker. And if the vga port doesn't flicker, sw is even less likely the problem.
If you bet the odds, you'd bet on a bad display cable. Won't hurt to try replugging it.
If that doesn't help, then your monitor may be dying....
