ColorMFA

Hello, I installed the device yesterday and everything was working fine in the car. This morning I turned on the ignition and the screen did flicker. I checked the wiring but it looked fine to me. I started the engine for a few minutes to make sure the battery voltage is not low. It did not help. I detached the screen from the mainboard and attached it again. After that I powered it with my lab bench power supply with 12V but had the same error. Any ideas whats wrong or what to check?

It looks like a memory problem.
How did you secure the main PCB to cluster ? Where did you stick the double-sided tape ? Did you use acid flux when soldering ?

Hi, I stacked 6 tesa powerstrips (total thickness 4mm) and sticked them on U13 and U12. My solder contains 2,5% colophony, which seems to contain organic acid. I did not add any additional flux and it doesn't look like the flux came in contact with any ICs.
I took a video of the flickering https://www.youtube.com/watch?v=sC-0dEHzwm0

Do not need additional video.
Try to clean memory chips (3 big chips at back side, U12, U13, U14) using clean alcohol (methyl or ethyl).
If it doesn't help, write PM to Dirtylime about this problem.

Unfortunately cleaning did not help. I'll contact Dirtylime. Thank You

Hi, I wrote a PM to Dirtylime and sent him a reminder a few days ago, but I got no response. What should I do now to solve this issue? Appreciate your help.

He should write to you shortly.

Thank you!

Hi,
unfortunately the problem is still not solved. Dirtylime told me he would send a replacement board on 28 of June.
To this day it still has not arrived. I asked him for the status 4 weeks ago, but he didn't answer.
I am not an impatient person, but this is taking way too long now. Please help me with this issue.

He should send you a tracking number.

Hi. I got the tracking number. But there is no progress. When will it be shipped?
