Some time after rooting my TV with SamyGO, I am now experiencing a black screen when I power on my TV. The backlight does work, but there is no image. Sound works completely fine.
I performed an EEPROM reset, but this didn't help.
I can also still connect to my TV over FTP. Is there any way I can upgrade/restore my TV through this connection?
You can make screenshots with lib screen shot and watch them on PC. That's what I do with broken TV. Also I wouldn't suggest UPgrading, it's much better to DOWNgrade
If you want me to help you please paste FULL log(s) to "spoiler"/"code" bbcodes or provide link(s) to pasted file(s) on http://ctrlv.it/ Otherwise "NO HELP"!!!
If you want root DISABLE internet access to your device!!!!
DO NOT EVER INSTALL FIRMWARE UPGRADE !!!!
