I called the LG local service and made a servise request. When they came home they only opened the back of the television and clean and fixed the sockets. It means there was a socket cable that was wrapped. They opened it and flattened it. My problem resolved my TV is working properly and they didn't make any FW downgrade. My firmvire version is 05.80.15 Ithink you need to call your local LG service and tell them my story 🙂
 
 

Thanks for reply. I want to try my chance with local LG service.  I will inform you if they will fix my problem.  Thanks again.

I updated my 49SJ800V TV's firmware from 04.70.95 to 05.80.15 and my smart remote controller not working properly. I can't use cursor and back button also i have connection problem with LAN and WLAN. I use my tv with cable connection but every 15 minutes LAN disconnecting and try to connect again. I resetted my tv to factory settings but  result is same.  I can't  use my tv now normally. how can i downgrade my tv's to last working firmware. I couldn' t find old firmware.  Could you help me to downgrade my tv' s FW ?
