TCU TurboLamik

Hi, I would like to ask for some help as I am currently having a problem with the display it was working fine and suddenly goes all green and now it just shows random numbers.

have same issue sometimes, in that case TCU like in limp mode with blank screen or blinking characters, selector leds on, but sometimes off.
If that happens car wont sleep automatically. Then i need to send poweroff command from tunerpro for re-boot TCU in normal state or reconnect power supply.
Problem observed from beginning using tcu for last 2 months, before i thinked problem in cold outside temperatures, but now when ambient temp is =>15deg it anyway happens randomly.

Turns out as I modded the screen to fit the dash the soldering was not good and it disconnected after like a few months. Resoldered and problem solved
