Have noticed in the last few days the picture with my Motorola 6200 and LG 50PK550 plasma has been flickering and going dark then light then dark etc. in picture brightness. I find I have to really jack my brightness and contrast to get a watchable picture. Could my box be going bad? I haven't noticed this on any other source on the tv.

It's possible it is simply the one input you are using that has become defective. If you are using Component, it could be caused by a bad ground, though that's not something that would pop up out of nowhere.

If you are using Component, try using the DVI port on the Moto instead (you may need a DVI > HDMI cable/adapter, I don't think the LG 50PK550 has a DVI port).


Edit: Well, scratch that. Beat me with your last post. I doubt it would be the DVI/HDMI cable, as it is digital. If the cable was defective, you wouldn't get any video at all.

This could be good chance to go in to a Cogeco store and swap your DCT6200 for the new Motorola DCX700 which has HDMI ;)
