On the picture we have failing car scales main control panel.
These are ~20(?) years old, you can see 8 AA batteries are power supply. The screen barely shows four zeros - so the device is kind of alive but not really
I was able to find a datasheet for the BT21608 screen. Between pins #1 & #2, I got a steady 5 volts - that's the main screen power.
Between pins #13 & #14 - LED backlight - I got a variable voltage, I saw as little as 2.10 to as high as 2.75 volts. I believe this is wrong.
That's the limit of my troubleshooting abilities. I wonder what is the chance of finding anyone to repair this piece of hardware, and what would be the best place to look? My local craiglist repairs either iPhones or appliances, and this random device is kind of in between. Chicago South suburbs.
