    MTG2500 Backlight Causing Electrical Interference

    Hi,

    I’m sure no one is still using an MTG2500 these days, but I broke mine out and it seems as though the backlight has decided to **** out on me. When plugged in, the display flickers like crazy and won’t properly boot. It won’t beep or anything.

    I decided to take the device apart and I unplugged the backlight. After doing that, the scanner boots normally although of course it is nearly impossible to see the text on the screen. Obviously something is shorting or causing major electrical interference, but I’m curious if anyone else ever experienced this issue and maybe resolved it. The scanner works as intended without the backlight and there doesn’t appear to be any blown capacitors on either the display board or the main board.
Working...
