Hi there!
I connected accidentally screen to DISPLAY port inversly, then there is only solid red LED. I also notice some signs of overheating on 3.3v coil (marked by red on the picture).
There were no any voltages, only 5V.
There are shortage on line 1_1 DDR and on VCORE
So I take off MXL7704-P4, then the short is still there.
I solder the new chip MXL and made a short circuit test.
I get ~0.03A with 1.1V, similar result on DDR and VCORE, nothing is getting hot.
Could You point out some direction or idea to repear the board ?
marked by blue - little damage on port during soldering
