Car roof 7" LCD MM 7000 S

Hi,
i have problem with this device. If no input signal is given, then LCD should be blue, in my case is white. If input signal is present, then on screen is visible picture, but only in light violette color. Other colors are missing. Also OSD is not working (not visible on screen), but sometimes i can change some settings by "blind" pressing Menu and vol+ and vol - keys. For example change format from 4:3 to 16:9 etc.

Inside of monitor are IC's:

Myson MTV018P24 + 24c02
IR3Y29B
UPS017

PCB marking:
RFP-769
p/n:371-001032-5

Attached is dump from Myson external memory.

Any idea where the problem can be ?

jordan1sk, try to erase EEPROM(24C02). I don't think it's possible to find good dump for this monitor.
