Upgrade issues after crash

My 329x out of the blue apparently stopped sending HDMI signal @ 720p/60Hz - No Signal. Tried on 3 other sets with multiple known good HDMI cables and got the same response.

 

I should note that none of my TV’s support better than 720p. One has HDMI(MHS) capability.

 

In any event I headed here to check on possible solutions and applied the current Android 7 firmware from this site.

 

Despite what appeared to be a good install, now on start up I see a screen message indicating resolution is 1080/60Hz on the MHS capable set and ‘incompatible format’ displayed on the other two sets.

 

On the MHS capable set, it boots to a scenic sunset with a large stylized N then I see a quick flash of the multi coloured boxes and then it begins cycling alternately through grey static, to black or occasionally solid blue, to a quick flash of the Language setup screen associated with a factory reset.

 

On at least two reboots, I eventually got a startup language screen that was at least accessible though the video display had a lot of various coloured horizontal lines running across.

 

On both these ‘successes???’, I stepped through language, date/time zone, set resolution to 720/60, and connected to network. At this point the box in-prompted began to download “ROM Update V002S901_20180821” which completed successfully and went to an auto reboot. I experienced exactly the same video issues as the initial firmware update introduced only this time, I see an occasional flash of the Home Screen so I know it has booted up OK.

 

I also tried using the Geniatech stock Android 7 firmware for MyGICA and get exactly the same results and have reverted back to the version available here. Unable to downgrade to Android 6 - thanks Google

 

It almost seems default resolution is set to 1080p/60 in the firmware.

 

Anyone have any thoughts about where I go next?

Well so much for that! MyGica tells me I will get better support here than they can provide - Ha!Ha!

In any event, it appears I was sold a refurbished box! I pulled the board to see if there might be something obvious. There was. The HDMI connector has obviously been re-soldered, And very poorly at that with solder being laid down even on to the ground contact that runs around the board edges. So much for QC.
