Oh, it's a | not an I, thanks for that! Looks like this is the backlight driver... makes sense.
I'll try checking again on monday, i left it at the shop and moved into something else for the time being.

Baykunl DRO Digital Readout D80M-3V - TFT LCD no image, backlight works
Hello everyone
A friend gave me this Baykunl D80 DRO (Digital Readout) he uses for a lathe/milling machine. The LCD stopped working, shows no image or color whatsoever, but the backlight works.
When you power up, sometimes you can see a brief image but for like 1ms then it goes black. That kinda tells me the LCD is actually good and the issue lies elsewhere.
The board has:- 1x ST STM32F103VET6 Micro-controller
- 1x RAIO RA8876LN4 LCD controller
- 1x Winbond W9864G6KH-6 SDRAM
- 1x Winbond W25Q128JV Serial Flash Memory
- 1x ATMEL ATMLH834 EEPROM
- 3x Texas
