Actually this is the problem. You`re not the first who complaints about this and i haven`t read any posted solution here. You could try to compare service menu values with ones from same TV model with working touch panel and change it. Or use ExLink to change if not able to use normal service menu.

Finally, I edited Source menu. All the hidden menu is editable. I no longer have non-existent connections.
also I found the point which select type of WIFI (Cable/ Ext-wifi/ Int-wifi). I chose Ext-wifi but my tv steel did not see my Trendnet 644 Wifi adapter with samsung pid/vid.
What should I do to connect my Trendnet 644?

about buttons, What do you think Format mtd_rwarea will help me ?

I send IR CODES FOR "FACTORY" AND "3SPEED" BUTTONS! i use my Nokia N93 + Psiloc irRemote.
Here i post pictures of Extended Service menu.
Please tell me can i flash the UE40D5003 (In the service menu UE40D5000) in firmware from UExxD5000?
it seems to me there is no module in Firmware for WiFi support in UE40D5003.
My Firmware T-MSU4DEUC - 1007.2
T-MSU4DEUS - 1001
may be the old F/W have support EXT-Wifi. where to get the old firmware???

Thanks for the photos. I don`t think older firmware enable your wanted feature. Most probably this depends from model in service menu. But i`m not sure if changing model won`t brick your TV....)
