@anish ,Anish, Remove batteries from remote to verify that the channel select button on remote is not stuck. If still changing channels check the channel button on TV itself, press the channel button several times quickly/repeatably to see if it is stuck and will start working. If this does not do it, try a reset, hold down the menu button on the top or side of your TV for at least 10-15 seconds. A on screen menu will appear asking you to enter the time, date and location settings. Follow the on screen instructions, and once completed your TV will reset to factory settings. If TV under warranty return for repair/replacement/refund as the board inside TV may be faulty. If out of warranty, with TV unplugged, wait a couple hours and remove back and locate wires going to the on board channel changing switch/button and unplug it. Re assemble TV and see if it will stop changing channels and work off remote, if it does you know the switch /button assy. is faulty. Good luck.
I hope this helped you out, if so let me know by pressing the helpful button.
