Philips 42: Turns off when cold & Picture randomly fading in/out
I have a 42 inch flat TV with ambilight, it's about 5 years old. The picture will randomly go very dim where you can barely see anything. When this happens it typically comes back in about 10 minutes. Comcast has already installed a booster. Not sure if this is related to the cable or the TV itself. I also do not have HDMI hooked up, as I don't have an HDMI box yet.
Also, another issue I'm having is when it is cold, my TV will not stay on until I turn it on about 15 times. It will turn itself off immediately until it gets warmed up.
