I had a power failure when trying to upgrade the FW of my 42PFL9603D to version 103. After that the TV started rebooting every 20-30 seconds. I have read in the forum about the Back-up Software Upgrade mode, so I decided to try it, but the FW upgrade fails with error that it could not program it. Since then the TV stays in that mode. Is there anyway to exit it?

Thank you in advance,
