Our tv changes from the channel its on to the input channel by itself. Sometimes just keeps switching back and forth or just stays on input 2. What is the problem? the tv is about 4 yrs old. Anyone else experience this problem? What will we need to do to fix this? or, is the tv shot??
Well, the only thing that seems to be working so far is to plug AV cables into the "input 2" ports (on the front of TV). I plugged in my PS2, without turning it on. It has not switched at random since (about 30 minutes - it had been switching off and on for the past 2 hours). Anyone else have similar success?

Okay, does this tv have a built in DIGITAL tuner? Most tv's only have an analog tuner. You can tell the difference while you are changing the channels. If the channel indicates 2.1 or 2.2 and so forth, it is on a digital channel mode. If you change the channel and it indicated 2, 3, 4, etc. it is analog. If it has digital capability change the input until you see 2.1, 3.4 etc. If you cycle through all the inputs on the tv like, input 1 (TV) input 2(DVD) input 3(HDMI) and so forth and you never see the digital channel you most likely do not have a digital tuner. You will need to purchase a digital converter which will convert it to analog and you can watch it by placing you tv on analog channel 3 just like the old vcr's. Hope this helps and please don't forget to rate this solution.
Picture tubes rarely go bad. You have a bad connection or something on the circuit board that is breaking down due to the temperature change . Probably an easy fix. Not something an unqualified person can do though. Your local shop should fix this for about $60-100.
