I have just discovered what I believe to be a "dead pixel" on my HLN5065W...to wit: there is a permanent black spot in the lower right quadrant of the screen. I purchased this set about three weeks ago from Best Buy. I haven't yet brought this to their attention (as I would like to first become better informed on this issue).


Has anyone else had this problem?

Can it be fixed?...or is a swap for a new set advisable?

Anything other feedback on this issue?


Thanks very much!

Samsung/TI supposedly has a "zero defect" policy on the DLP chip--you should eventually be able to get it fixed if you try hard enough.

According to a flyer that came with my HLM617W, dead pixels are part of the manufacturing process, and to be expected. (see other thread on this issue, with pictures) I had a dead bright white pixel which was very distracting. However, if it is something that is not noticeable from viewing distance, I wouldn't worry about it.

Samsung replaced my 507 because of a dead pixel (stuck mirror). It can be repaired, but only by replacing the entire optical engine. I got that dumb flyer with the dead pixel disclaimer with my 507. IMO, that is BS. A dead pixel (at least a full black or full white dead pixel) on one of these TVs is very noticeable from 8' (more so than on a 50" GWII), and if you're paying $3000+ there's no way you should tolerate this kind of defect.

I agree! Once you notice a dead pixal it is very annoying and you see it all the time. If a manufacture can't produce a product without dead pixals, then maybe they shouldn't produce the product at all. These newer TV's are just to expensive for us not to get what we pay for.

I agree. But, have you ruled out dirt on the inside of the screen? If the black spot isn't the exact size it it's peers then maybe it is on the screen and can be removed.

Haven't seen the flyer, but that directly conflicts with what TI employees have stated here. Supposedly no DLP chips leave the TI factory with bad mirrors.


And even then, that flyer is pretty worthless if it doesn't explicitly state how many pixels need to be bad to be considered a defect. Probably just to scare off the uninitiated.


If TI is planning on competing with LCD this makes sense as a competitive advantage.


Also, I don't think theaters are planning on getting bad DMD's and the manufacturing procedure should be the same.
