37 Westinghouse LCD burn in

post #1 of 24
Thread Starter 
I've had a westinghouse hooked up to my PC for about 1.5 years now. There is a wave on the left size of the screen where its darker. Its not a straight line it starts at the top left and comes out a few inches then comes back in. It really looks bad when you have a blue background. Its kinda hard to explain what it looks like. I've tried an all white back ground and it hasnt helped. I thought LCD's werent suppose to burn in? I'm almost about to junk this thing and go buy a new one.

How in the world do you know this "wave" is in fact burn-in?

I have over 300 LCD's on my network that run 24/7 and half of them have been doing so for 5 yrs and ZERO burn-in and I own four LCD TV's and dual 19" monitors and zero. I've never seen burn-in replicated on an LCD Monitor or TV and my network includes 400 PC's which I buy and manage them and no such effect. What you describe sounds more like banding not burn-in, perhaps overheating has replicated the wave on the panel as I fail to see how backlighting could burn-in it's light onto glass substrate.

True burn-in is close to impossible if you study the layers involved in an LCD unless of course you place a static image and leave it there for inifinity perhaps it may somehow replicate it. Owners Manuals will address it as a Caveat but it's the lawyers that place those paragraphs within not the engineers. Burn-in postings on LCD TV's are simply RARE as I've been here almost daily for 3 yrs and it's rare indeed.

I have an LCD that developed burn in over about 3 years of use. I used to play warcraft (though never more than about 15 hours per week - for less than a year on that monitor) on it. I refer to it as burn in (permanent image retention) because as of this thanksgiving break, it still retains the image of the distinctive default WoW player con, along with the action bars. You can also clearly see the XP "start" menu if you display a blank screen of any color. The monitor hasn't been used intensively since I replaced it in the summer of 2006 with a dell 2407. Still, at $700, the Samsung 191T in question wasn't exactly a budget LCD when I purchased it in the summer of '03.

Its possible the waves I'm describing are not burn in. But I also see my desktop icons right around the same area, so that would be burn in. Is it possible I can get westinghouse to fix this? My tv is out of warranty so I would have to probably pay.

I can personally affirm that burn in is indeed possible on an LCD, namely my 47 inch Westinghouse. Two lines down the sides where 4x3 content ends. I tried 20 hours of just having white onscreen as per the Westinghouse techs.

I have the Best Buy tech coming out next week. Good thing this is online:

I can also vouch for the BS statement that "LCDs are NOT subject to burn-in."...unfortunately they are. Just like "Adam Oregon" stated (ironically I too am Adam and I live in Oregon), I have a 47" Westinghouse monitor that started showing signs of burn-in months ago. On the right side of the screen, I have a very prominant, static, dark line where the border of the 4:3 sidebar resides. While watching certain colors in HD, the veritcal line can be seen very well...which is very annoying and frustrating. I also notice darker shades of color in the areas where the 4:3 sidebars should be.

My problem is, Best Buy states that this is not covered under warranty...neither by them or Westinghouse. I have not spoken with Westinghouse yet, but Best Buy states there is nothing they can do.

"Adam Oregon"...how did you get Best Buy to acknowledge your issue and come out to take a look at it? Westinghouse's FAQ even states that their LCDs are not subject to burn-in. Thanks in advance for the help.

I also have something resembling burn in on one of my 20" dell lcd monitors at work. The minimize, maximize and close icons are clearly visible in the upper left hand corner of the monitor. Power cycling the monitor won't make it go away.

Coincidently, the blue windows xp background is slightly darker in that section. The burn in is only present in this section. The darkened section starts about 3/8" down from the top on the right side and decreases as it moves to the left side of the screen. Other icons and the task bar are not burned in.

It is like that section has become damaged and allows the burn in to occur.

It is very strange.

Its true that LCDs are not supposed to burn in. Still some of them do. I have seen it before. It's not the actual LCD that is burned! It is the Anti-glare coating layer or the polarizer film that is becoming discolored. This is a result of cheap-o manufacturing process. The panel manufacturer is using substandard film layers for AG and polarizer. You know, lets say you owned a MP3 player company. You go to China to check out your manufacturing chain. When you get there you are taken to a nice factory with nice equipment and everyone has clean suits on. What you don't know is when you leave, they quickly usher everyone out of the fake factory into the real one. Inside the real factory the conditions are deplorable and the workers are forced to live there in dorms on site. Burn in on a LCD is a defect and the manufacturer should replace it at their cost. I have an LG computer monitor that has been on the same screen for two years! No burn in what so ever! Don't put up with it, if you can help it.

How to protect LCDs against burn in.

Display a white screen on your LCD for 24 hours after it is out of the box. Then do a black screen for 24 hours. If you have back-light control, set it at 100%. This will pre-expose the whole screen to the UV from the lamp and set any glue that may not be dry under the layers.

Where / How do you "select" a white screen to display from?

My Westinghouse got burn in or image retention as they call it after 4 months of use. As far as the white screen i attached my lcd to my computer and downloaded this

Funny, but I was just watching a segment on our local news (Atlanta) called "HDTV Nightmares." They talk about complaints with specific brands of flat panel HDTV and basically come out and say not to buy Trutech, Prima, Westinghouse, or Polaroid LCD TV's, due to the fact that they are basically inferior quality, and when they do break (which is almost inevitable) you can't get service parts. They actually say get a namebrand "like Samsung" and then they reference a Consumer Reports article.

I don't think I recall a news group trashing brands of consumer electronics products so candidly, especially if some of their big box store advertisers still sell those brands. Interesting report.

So, how (if at all) did you guys get rid of the black bar on your monitors? I've got a Westinghouse 47" just like alfisher04 (and some others here). It's only a few months old, but I've got a thin black line where the letterbox borders are. I bought it online, but I'm hoping that someone knows a slick fix. Right? RIGHT?!
post #13 of 24
When you say thin black line, is it like a ghost image or is there a line of pixels out?

I doubt you will be able to make it go away. Call Westing House and make them replace it. And no, you wont send it to them on your dime. It is a defect. This is an LCD panel not a plasma. It sucks that these thing happen that way. I have a Westing House TX series 42". I have been watching movies on it since I bought it. There is no sign of burn in what so ever. On top of that, I prefer to watch SD TV with the black bars because I hate seeing actors faces stretched out like the front of a Peterbuilt. When you do get a new unit, go ahead with the procedure above and try to prevent this from happening again. Watch your SD content stretched out for a few months. If the screen gets blurry after a while, it is a sure sign that they are having problems with either the application of the glue, or with the film it self. Keep kicking it right back at them until they fix the problem.

I have a 5-month-old Westinghouse SK-32H240S that also has the 4:3 black line down the right side (because the wife just will not watch SD content stretched). It's actually my 2nd one, I took the first one back because of the black line it got.

I was told by Westinghouse tech support that it was a flaw that would be covered under warranty, and that I could try white-screening the TV overnight.

I'm currently running the eaprogramming break-in DVD on it, still going since last night, but I still see the line. It's most visible when the break-in DVD is showing blue and pink screens.

Will this DVD do any good, or has that black line become a permanent fixture on the TV? What about the PixelProtector DVD? Will it do any good?

Thanks,
dan

I brought a westinghouse 32 inch tv from bb in December 17 2007. Mid April i got the thin vertical line where the 4:3 crops. i had an extended warranty and had to fight with best buy as they said burn in(image retention is what they call it) isnt covered. finally got westinghouse to give some approval code to take the tv back. i know have a Samsung 32a550 and have to watch everything full screen as im afraid i would get another line. Before i got my 550 i went to tweeter next door to where i work and to my suprise they had a tv on display with a thin line from top to bottom on the left side. Anyway i attach my computer to my tv and left it on for over 12 hours with the bright light and it didnt go away. lcds do get burn in they just call it image retention lol
post #16 of 24
Is this a problem that happens on other brands? I've never seen such a thing before I got this Westinghouse.
post #17 of 24
I put 5000 hours per year on a ViewSonic... at year 2 icons & 3:4 bars stood visible overnight. Year 3, backlight went yellow at the ends and previous web pages stayed visible for a few minutes... another 6 months and it developed a pixel line that grew each on/off cycle in both width & height. I'm shopping again.
post #18 of 24
I bought my parents a 27 inch over a year ago and it has the line. They just deal with it. Believe me, the line does widen and it also spreads. What a piece of garbage. My 32 inch shows no signs of anything wrong with it. I watch about 90% HD content. So far so good with my 32 inch Westy.
post #19 of 24
I was told by Westinghouse support that it is a warranty issue, and if I would just send my TV in, they would fix it or replace it. Turn around time they SAID was about 1 week.

They don't do advance replacement, like say, Dell will.

So I guess I'm just going to be stuck with it until I get a new one.
post #20 of 24
I too have a problem with a westinghouse 37". There are dark shadows on the left and right sides of the screen (very prominent with solid color backgrounds). Tried the white screen for days to no avail.

Does anyone know if Westinghouse will fix this out of warranty? I definitely expected my 1200 dollar TV to last more than a year without such a terrible defect.
post #21 of 24
This is apparently a fix for image retention on LCD's.

I'd be interested to hear if it works.

Sorry to bump and old thread but my 37" Westinghouse has this same exact wave of burn-in. It's very strange.

my westinghouse does this too.... mostly image retention and it eventually goes away using an anti-burn in tool... still annoying though, you'd think it was a plasma.

This also could be de-lamination of the screen/panel. Does not look like any "burn-in".
