Yeah, their rootkit and other DRM strategies have caused me to boycott any and all SONY products.

It is a dark spot/triangular area, but some of the picture does show through. No movement of the TV set occurred.

Duluth, Minnesota USA. if I have a friend help me, do you think we could safely remove the front screen without a zillion parts falling out or whateer? Looks to be a dozen or so screws holding the front cover over the screen, I should think that could be removed to allow the screen to be removed and examined?

1: On our Samsung (50") the lamp type is on a label on the back left. I have one in the closet for $115. The 50" is a 100 watt unit and IIRC, the 61" is a 120 watter. Might be a bit more but I doubt $600.

i agree with you Unclejr, BUT, the SXRD is a smoking set, i must admit.

I'd wait a bit anyway, regardless of the PQ of the SXRD v. Sammy.. I'd wait to see when there are 1080p sets that take 1080p INPUTS. I'd also wait to see if there's a new gen of 1080p NON-wobulated DLPs. I figure that's about the threshhold of PQ that I'll beable to notice (at least for now).

Should be fine. All the electronics are in the base.

I work with damaged fright and store returns in a salvage place .

I have taken the face off of about 5 or 6 DLP sets to pop the screens back in or replace a mirror . With this under my belt i have noticed every brand comes apart different Panasonic & toshiba in the 2006 era are a nighnmare . I took two Samsung apart , it was not to bad . just put the set out on the floor or table so you can start removing screws .

From what i have seen the 3 piece screen has clear tape runnnig all the way around the edges holding the 3 sheets together , you can slit the tape just enough to try & wipe off whatever may have gotten in there then tape it back with scotch tape its about the same as original tape .

If you are carfull and well organized , no kids , dogs or whatever this shoud not be a big deal to at least get apart . Also check in your area-s for any tv shops or salvage business that may have new damaged stuff like we do here . One person here found a good

Of course there isn't any 1080p video available today except from PC-based sources, so those few sets that do have 1080p native inputs (HP comes to mind) won't have any practical source material.

I've read all these posts, and there's no correct answer to this problem. Whats happened is that some of the cleaning solution has run down to the bottom of the screen, into the U shaped ledge that holds the screen, and the fresnel lens behind it. It has then "wicked" up between the two sheets of plastic, and is causing the dark spot. You can probably get the spot to change shape slightly if you press gently on the screen. And its a very, very small amount of water. So, to fix it, get a hair dryer. Put it on LOW (!!!) and slowly move it back and forth over the wet spot. Dont want to get it hot, just warm to make the liquid evaporate. The spot should disappear, unless the cleaning fluid was very, very contaminated with dirt, doubtful. No new screen needed. BTW, some time back, I had a HD big screen Toshiba come in that had been marked on with crayons, magic markers, and who-knows-what -else by children. I used a can of WD-40 and a fine toothbrush to clean the screen, worked like a charm. Had a great picture, sold it for over $600. Try drying your screen before you do something drastic. And, I have to admit, I've done the same thing, and created exactly the same problem when I clean my 60" Pioneer. The problem will go away with time,(evaporation) but the hair dryer will cure the problem quicker. Oh, and I use warm soapy water on the Pioneer. In very sparing amounts.... HTH Deke

GREAT IDEA!!!!

That's exactly what could have happened. If any cleaner got between the screen and the outer protective screen, it will cause this type of problem. There shouldn't be any damage to the screen, but it may take a while for it to dry completely. It might have to be disassembled for proper cleaning, but there's no serious damage. Glass cleaner shouldn't hurt the screen if used occasionally. Andy Cuffe

oh man did i dodge a bullet on this one! The screen is back to almost normal, that black rectangle is 95% gone, I had the heat in my home turned up to 70 the past couple of days because of cold weather here in northern MN, and brought up the hair dryer to do what you said and the spot was almost gone! Evaporation from the heat in the house and low humidity. I still blew the hair dryer on it for awhile, will do so more later. I can live with it the way it is, hopefully more of it will still go away.

I just do not understand what causes the black coloration if it is just a liquid, that is the bluish glass cleaner liquid that got up there. Just curious, if anybody knows. Polarization of the liquid or something?

Thanks all for the help, even though this time I did not have to buy a new screen. I was just SICK over the thought of $800+, I am sure going to be VERY careful now about cleaning the TV, taking better care of it, reading manuals (ok, yeah right, like we all say we will wash and wax a new car the first days after driving off the Dealer's lot, LOL).

Spot is almost gone from drying, and like you say I might at worst have to pay $100 for a repairman to come and clean the inside of the screen if some of that "black" residue sticks and does not evaporate. Man that is much better than a new TV, or $800 to replace a screen!

problem.

the

of

very,

dirt,

The water probably changes the refraction angle of the light coming thru the fresnel, and the front screen. Since the angle of the light coming thru the screen is different thru the liquid, it looks black, or dark, in comparison to the "normal" light. Now that you've cleaned the screen, be glad you dont have to worry about cleaning the dust off the crt lenses inside. Cleaning a years worth of dust off the lenses in my Pioneer makes a very noticeable difference. I usually do it in the fall, right before the new TV season starts. Theres a D-ILA in my near future. Pro series. Youre welcome. Deke

Just whatever you do in the future, never spray cleaner directly on the tv screen, apply it to a cloth then clean with that. Also never clean a TV with it turned on. Static just attracts dust like a magnet.

Bullshit. DLT TVs don't have any voltage on the screen. You're thinking of a CRT.
