Re: Grundig 55 GUB 8860 - bad T-Con or bad panel?
I have an update but at the moment it is not a good one:
I did some trial and error with various USB sticks and SW versions, pressing buttons, pluggin in, plugging out, never got anything on the screen.
I found out that pressing the "+" Button while plugging in with the USB stick in USB1 caused the TV to do "something". It briefly turned on the backlight, like it was starting and then shut off (all within 5 Seconds or so).
I figured maybe (I know you doubted that, but MAYBE) the T-con IS broken. So I unplugged the left ribbon again and performed the update procedure.
For a very short moment, not more than a second the large white letters and the progress bar of the software update screen were visible on one half of the screen.
It was really just a short flash, I only know it was the update screen, because I recognized it from some of the PDF guides.
I powered the set up once more with the ribbon disconnected and got to the menu again on half the screen. I am not 100% sure but I think the menu looked different from before. It had colorful Icons of Netflix or YouTube that I do not recall heaving seen during my cooling spray tests.
I connected the ribbon again and tried to install the old firmware.
And ever since then it has gotten worse.
I am not getting any picture at all now. Not even with the ribbon disconnected.
When I start the set and push the menu button on the remote the backlight gets brighter but nothng is visible on the screen
