Hello,

I did look at the avi, but the horrorble logo is blocking the view.
I see some numbers and flashing LLL.

Upload the video to youtube.
Then you can embed it into the post.

It could be a lot of things. Almost like asking "why does my car not go?".
A couple of questions...
First, does the device still work, and just the display have a fault?
Do you have any electronics repair experience?

Ok.
First thing I would try is to test the capacitors in the power supply.
Remove them and measure the capacitance.
Often, old caps cause trouble.
