LG TV goes to standby by itself
I have a 2 years old LG LCD TV 22LD350 (warranty over). Few months ago, it has started going to sleep by itself, once every 3-4 days, then last week it was happening every day and now every 5 minutes.
So it goes to standby but I can't wake it directly, I have to wait approximatively 30 seconds to be able to turn it on again.
What could it be ? The power supply ? The board ? How can I figure it and can I repair it ?
Thanks for your help
Is this a good question?
