Can you view your recordings when you connect the camcorder to a TV?
If you can see your recording on the TV then it may be just a problem with the LCD screen in the camera.
When trying to view a recording in the LCD screen (I realize that you can't see anything on the screen) try shining a flashlight at an angle close to the LCD screen and check if you can see any images on the screen.
If you can see images then it is a LCD screen backlight problem or a screen backlight power supply problem from the motherboard.
If you can't see images then it might be a LCD screen and backlight or motherboard problem.
Since you can see images OK on the TV then more likely it is a LCD screen problem.
If you can't see your recording on the TV then most likely it is a lens or motherboard problem.
Here's the service manual that will help.
It has the disassembly procedure (for the LCD unit see p.5-14), the parts list and schematic diagrams as well.
A quick search online for the LCD unit showed no results for suppliers. You may have better luck.
Hopefully this is of some help.
