UE46D6530WSXXC reboots after firmware update.

My UE46D6530WSXXC turns off and restarts immediately, reboots. This started after firmware update, in march 2013,to T-GASDEUC-1021.0 or T-GASDEUC-1024.0.
This happens sometimes after a short time of being on, 20-30 min, after turning it on, or past few hours.
With the original firmware worked fine for 1 year and a half.
Will an EEPROM reset, revert the firmware to the original?
Changing the type and the model in the service menu, will change de firmware to the original of that new type and model?
What about D-Series Firmware Downgrade? Is it my only choice?
What can i do solve this?
Thank`s everyone

Hi, eeprom reset wont help you. Try to switch off Watchdog in service menu. If this wont help and problem still persists, then firmware downgrade...
