I have been having this problem for quite some time now. The TV is about 2 years old. The problem is that the LED Screen keeps flickering from vivid color mode to a duller color type every 5 to 10 seconds. Then later on the screen started to freeze when switching scenes while playing movies, etc. It was having a ghost effect where the past scene is still visible in a faded form for around 3 seconds . I have done a self diagnosis and it is giving a lot of errors, and also one of the hdmi ports have also stopped playing audio.
Please help me to rectify the possible problem. Thanks in advance
