Finally!!
Took several days trying to recover the panel and finally I made it.
The information in the Wiki and this thread has not helped me at all.
Change the model to D5800, did the steps in the wiki and got nothing.
So today again put D5003, update firmware from 1007-1008 (T-MSU4DEUC-1008.0)
- After updating I returned to the service menu.
- Activate extended menu.
- Change Model to D5800
- Control - Sub Option:
- KEY SENSITIVITY 74
- Control - Config Option:
- Num of AV 0
- Num of COMP 0
- Num of HDMI 2
- Numbers of PC 0
- Numbers of USB PORT 1
- Num of PANEL KEY 7, hit return and go back to put 6
- Type OF KEY PANEL PDPHoriz, hit return and go back to put Horizontal
- Vendor Fuction AUTO
- You press Return to get to the main menu
- Exit the menu with "3speed + factory"
- Turn off the TV
- Turn it on from the remote
- DONE!
Worked for me finally!!
Type: 22A6TF1E, Model: UE22D5003 (Changed to UE22D5800), T-MSU4DEUC-1008.0
I hope that helps
