Hi, maybe take a look here.
Another device, another issue... I'm using LE with RPi, in the case when the RPi restart, when the TV is in standby, had EDID issue, so I made an EDID dump with "getedid create" command. Something similar you can try... If you can save your TV's edid data with another device and put it in the right place in your Wetek?
Wow, I finally fixed my device after a lot of effort and followed the output pins hdmi
I found pin 16 with a voltage of 0 volts !!! And I changed the resistor no 9R6 With one I took from a broken receiver . As a result, everything came back to work 1920X1080 and sound 
I'm sorry for bothering you and thank you again
One of my guesses was right then! .. but nice work on fixing it
