When the TV is plugged on the AC power the red light at the bottom corner is lighting ON, but it is very dim and when i switch the TV ON nothing is happening. So, it does receive the power, but it does not show anything when switching ON.
If that light doesn’t turn green when you attempt to power on via the remote or tv, your board is too old. TV’s have a life of about 5 years these days. It’s not worth replacing the board either. Costs just about as much as a brand new tv. Recommend you dispose and buy a new tv.
