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

Sorry to hear that... Well then it's obvious the issue is in the analog section somewhere... how about the antenna input?

I'm gonna take a stab at the vertical hold being the culprit. Older sets had an adjustment at the rear of the unit usually set into a spot off to itself. Slight turning of it either with a plastic screwdriver or fingers, if exposed, will usually remedy the issue.... that's what the 6SN7 TUBES USED TO HANDLE... VERTICAL HOLD. i THINK THEY'VE GONE ALL TO CHIPS NOW, BUT STILL SOME ADJUSTMENT SCREWS CAN BE PRESENT. SOMETIMES.

It also might not be sticking out of the back of the box either, so you have to look closely for it.... Call Mit and ask them about your model.
Optical engine... hmmm.... maybe that's a new word for 'IC chip'.

Hope they hurry.
$1800? Whoa!

I bet this is one time you're glad to have the extended warranty! I never buy those things myself. guess I've been fortunate. My near never used 61 inch Sony still plays well... but it's old school. 3 9 inch TVs are inside of it... or so the tech said.

The only thing I've had crap out on me since 2K were the Dell PCs I've had, a sony VCR/DVD player, and a chip went out in my 8 yr old Sony es receiver and cost me $125. hearing it after the fix, I was happy to have paid it as it was getting a little fuzzy sounding.... that all changed with the new chip... it sounds as good as new now.

Very good luck with your repair/replacement.
I didn't have my Mit big screen too long. Only a month or so. Sent it back and got the Sony instead. had I a room with controlled lighting, and knowing what I know now, I'd have gone with a projector. Period. No question.

Naturally, which ever resolution does more for you... take that option. having it repaired seems the best choice to me, if only a partial refund/rebate is offered.

If ya gotta take the money... for well under $1500 you can go BIG with a PJ + Screen. those DLP projectors work real good. Well, mine does anyways.

I'll keep a good thought for you in all this.
I can dig where you are coming from on that natual color bit. I was always drawn to that myself back when I was in the biz, but many aren't. Just like a hi fi stereo, the louder it can play, and have great extension on top and bottom, the more 'people catching' the thing will do in a store.

Now I'm all cartoony all the time, on my personal preset, and natural for when company arrives. Natural to them, is B&W almost to me.

Keeping fingers crossed for your experience to be most positive.

Merry Xmas too.
yep... if you are happy with that result, super. Congratulations.

Buy another warranty on the new set this go 'round as well?
