Question about Audio Players & Recorders
Mine faded away in two years, just out of the seller warranty! What a shame. I suspect they are investing in planned replacement. Sorry for bad news.

Are you referring VDF Display on page 4 on the pdf file?
I want to make sure we are talking about the same item.
Before you start working on it,I need to know can you able to do soldering and changing small component in this unit.
This unit can have a bulb or a true back lite on system under the display unit.
The function of the back light is just like a projector bulb.
The first step is to confirm the display is still working.
Use a small flash light and shine it in an angle to look from the other side for an image of ANY DISPLAY.
Move the volume up and down and look for character change in fade image.
I hope you can see something (even faded) on the display.
tap the surround area of the display to rule out intermittent connection problem.
If you are comfortable on opening up the unit then disconnect the open. Power it just a few second to discharge and capacitors.
Make use you open the unit slowly.
When you open the case look for any fragment(s) of electronic part(s).
This step can safe you a lot of troubleshooting time.
Check for a back lite bulb.
Check the voltage to the bulb (YOU WILL NEED TO power on the unit.....please be careful.)
Shine the flash light behind the display and look for bight display (segments)
IF all else fail.......apply light pressure on the display connect and check display on the front.
Please post question and result on the comment area. I will follow up it tomorrow.
