Intermittent on off...we had left our TV Off & unplugged for about 3 months. When we returned it took 5 or 6 tries to get the TV to come live. Then when we turned it off, the same thing happened when we tried to turn it on again. So when I did get it on, we left it running for 2 days and it worked just fine. Today after turning it off last night, I cannot seem to get it to come live no matter what. The little ON light at the bottom of the TV comes to green but no picture or sound.
