[tiamat81]

Hi, I have a problem with my Astra H GID display. It`s Siemens VDO KP
The display is working but there is a problem witch contrast. Some part must be
broken but I just don`t know where to look.
If anyone saw such a defect and could suggest something, I woluld be grateful.

Try heat board / ribbon while applying pressure with pencil rubber.
Or get replacement from scrapyard and swop eeprom

The display is replaced in the car, but I want to fix this one, i have gid display from vectra c for parts I swapped few things but no luck.
I will try to heat the board, and thanx for the idea, but i think there`s propobly one thing broken on it, but it`s hard to find out what it is. I woluld be grateful for more suggestions.
