Tracing light pad won't light up, any advice to fix it?

"I had the same problem. I tried two fingers, more pressure...and on. I was eventually able to fix it (it was a dislodged lead).

The white backing is held on by two-sided tape. You can cut it loose by inserting an x-acto between the back and the clear part. From there, gently remove the sheet of backing plastic. You can at this point see the wiring and circuitry. My problem was a lead pulled off from the LED strip. I simply soldered on a new wire to the strip and then soldered the new wire to the old–voila! You'll see once the back is off that it's cheaply assembled, and some of the leads can be pinched as they're routed around the perimeter.

I apologize I didn't take any pictures."

I have meet the same problem , and at last I changed to a XP-Pen Artist 15.6 Pro Drawing Tablet with Screen .

totally uselress piece of 拉屎

I have the same thing happening after just a few week of evening hours. The connector cord is already loose and wiggling and duct taping it everywhere is a cat and mouse game. Sometimes works, sometimes doesn’t. Slightest movement and it switches off. So fed up and now looking for a better quality manufacturer.
