Unti just shuts off

This unit is not repairable. I had the same problem with my unit. I had a certified LG repair shop look at the unit. Just to evaluate the unit was $85.00 after testing the unit they discovered parts and labor is much more than the original cost of the unit. I am furious. You can't used the speakers with any other unit. I will buy a DVD player seperate from the tuner in the future. DVD players are much cheaper and are easy to replace, but when you purchase an all in one you are trapped with an unrepairable unit. I will never buy LG again.
