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

thanks for the thoughts.

I have tried different inputs. different cables. Same problem unless I use HDMI then it is OK. There is no ground loop. TV plug is 2 prong. I have tried it direct or into Shunyata Hydra 4 with same results.

I ordered a tech to come over. It was worth to have that extended warranty I never buy but in this case I felt I may need it. Still have little over a year left on it. This was a good timing for this thing to crap out.

I just reaplized that my friend had the same problem whith a 73" Mitsubishi DLP and they ended up giving him a new TV. This was a while ago.
Funny thing is, they don't make the 52" DLP anymore, which is what I have. So if they can't repair this one, I wonder what they will offer.
yes. It is the optical engine....whatever it means. They will take it in for repair after the holidays.
$1800? Hell yeah I am glad I have opted for that extended warranty.

The tech said optical engine and also mumbled some other words that meant very little to me.

Interesting...you are probably right though, optical engine and light engine could be one and the same thing.
I hope they declare it not worth fixing and just give me a credit for the amount, so I can just buy a new 1080p plasma or an LCD, now for the same money I paid for this 1080i DLP tv.
The thing is, I really like this TV. The colors are very natural. The picture doesn't strike you immediately. It's not like the TVs in the store you walk in and get shocked by the colors of the displays, almost cartoon like colors. This TV does have a darn good picture and I've been happy with it. Plus it has a protective glass over screen, which was important to me at the time I bought it...my son was just learning to walk and started to explore things by touching them, so this glass is an excellent feature, although it glares. I am used to it.

I'll update the thread once I know what they will do - fix it ir give me a credit. I bought it at PC Richard, so the credit will be close to the full amount I paid, I think. At least that is what they gave my friend when his Mitsubishi TV that was still under warranty crapped out and they could not repair it. We'll see...
