I've had this tv for 10 years. The chassis is AEIP305. One day, it just started to shut off by itself. Tried power button but it didn't work. Then my son started giving it a swift bang on the side and it would come back on. Now, it has gotten to the point where it goes off almost every 10 minutes and he beats it to death on the front near the speakers until it comes back on, which sometimes it doesn't until it sits for a while. If no one hits it and leaves it alone, it eventually comes back on by itself and then turns itself back off. My husband wants to take it apart to see if he can "see" anything that might be causing it to do this, but I would rather have an expert opinion on what it might be and/or what to look for. My husband did open it up once and used spray air to give it a good clean, but that didn't help. It's not enclosed in an entertainment center, it's out in the open by itself.
Thanks so much for any help you can give!
