Toyota Yaris Display Dash Red line

[Stelaras26]

I read all the threads here,have fixed some clusters with the help of a member but i have one that is not similar to the photos or the info i have read here.>
If anyone could help,i would be gratefull!

When i power it on ,i have one small red line only !

check flex

[tazz75]

...and resolder all connection pin's...i mean display,flex and wire connected pins

[Stelaras26]

I have fully resoldered the whole pcb carefully,not a single change :P

Flex is not the issue in these,was never,some transistor or 1-2 resistors,but i dont know which.

Bump,still have not fixed this!
Any help?
