Mitsubishi DLP problem

If anyone knows what this might be...

I am getting Horizontal lines that run up or down the screen of my Mitsubishi DLP TV. This only happens on any input other than HDMI. With an HDMI source(be it the cable box or dvd player or laptop) the picture is clear. I have tried 3 component sources, 2 dvd player and a cable box, and all display same problem. The effect is similar to a magnetic interference you would get with a tube television if you place something that causes magentic field distortion(unshielded speaker for example).

I suspect the processor or converter or chip or whatever it is called in the DLP tv, is going, or on its way.

Any thoughts?

Thanks

Optical engine... hmmm.... maybe that's a new word for 'IC chip'.

Hope they hurry.

Do you mean light engine? This can be very expensive, making it actually not worth repairing. Not sure of your model, but I know some light engines in the Mits can be as much as $1800 with labor.The bulk of the cost being the light engine itself unless under warranty. In most cases a new TV is a better investment.
