Hello. I'm newly registered though I have been coming to this site for a few months. I hope that soemone can diagnose a problem for me.
I have a 70" Mitsubishi. A few days ago I turned it on and got a green screen (like the blue screen except green)and no sound. I tried turning it on and off without success. I then unplugged the TV for a few minutes. When I turned it back on I got a picture, but it was very bright. I have tried turning the brightness all the way down and it is still very bright, though now somewhat watchable.
What has happened here? How do I repair it? Thanks for your help!
