Hey.
The same thing happened on my TV.
Set the option EDID = ON then select EDID WRITE ALL

I do not understand why the photos are not visible.
I will explain in words.
Try in the menu "EDID" perform the item "EDID WRITE ALL". If after the word "wait" the message "fail" or something like that appears, the motherboard does not correspond to the UE46C7700 model.
If after the word "wait" the message "successful" appears, then everything is fine!

Note: to enter the service menu, turn off the TV, then quickly press on the remote control of your TV the next sequence INFO-MENU-MUTE-POWER

Well if the message "Mainbaird changed" appeared without you doing anything along with problems while booting then your Mainboard does not have a bright future. If youre lucky you can find a replacement Mainboard for UExxC6500 or C6800 these should fit for you and give you the upgrade for PVR/Timeshift

If you can't fix it using dvct tape, you are not using enough dvct tape.

if I go to the EDID menu and validate, nothing happens. can you help me.
thank you very much

its at least possible that your faulty power supply did some damage to those eeproms

Eeprom could be easy replaced. Worth to try. All what you need is moderate soldering skills and new atmel chip.

and new atmel chip.
will the mainboard be able to flash the new chip with data on its own?
