image on tv goes green

When changing channels, the screen on my Pioneer sometimes goes to bright green. The sound is OK. At that point we have to turn it off and then back on. I asked Comcast about that and they said it's a fault of the HDMI connection with their cable box.

I have a 56' Samsung DLP around 6 yrs old. I have replaced the bulb, color wheel and light engine board in the last 14 months so I have some experience. Luckily, I had an extended 5 yr. warranty on to cover the board which runs around $1k for the part.. ...Bulbs can last 1000 to 3000 hrs depending on the type of use the unit gets. Bulbs begin in to flicker, take longer to turn on and have decreased brightness as they begin to fail...Your set is a DLP given its age not an LED. You say you replaced the bulb/wheel module.?? They are two separate items...One has nothing to do with the other...Bulbs run $80-$125. The color wheels run $150 and up and are not that simple to replace...If bulb was just replaced I would take a look at the wheel. I was able to replace mine with a little help from youtube and some folks on AVSforum.

Let me know

Raks,

Your problem sounds like a drop in the picture signal that causes the screen to go green. Could be the HDMI cord/connection or it could be a drop in the picture signal from the cable company. The audio signal may be strong enough that the audio doesn't drop out. Just a possibility.

Now that you mention it, when I was having cable box issues a few months ago I was getting completely green screen. I took the cable box back and exchanged it and it's been fine since. I didn't get any part of the video feed when it happened.

My issues are definitely not related to a cable box. The TV has been in three locations in two houses and has the same issue no matter which source or electrical supply it is connected to.
