From some time I can see on the screen horisontal strips without any content (just black lines) and noise every 2 sec. (similar to SMPS restarting).
After small investigation I found out suspicious chip. It is located on the matrix PCB and it is getting hot after short time (matrix is labeled LM220WE5).
The name of the chip is MAX17077AETM.
I emailed Maxim customer support in order to get it but without success...
Does anybody own datasheet of the chip or know where to find it?
