Samsung forum: Halo Effect on LN52A750

So, what is the deal with the picture being transferred into the glass bezel that surrounds the screen. I'm talking about the glass or plastic bezel that frames the screen ~ the one that encompasses the touch of color.

The more I have read about it in different forums, the more I realize that it is not just a problem with my tv, it is problematic with all 7 series, well, at least the 46 and 52's.

It's a little irriatating, and way more so in a dark room. If the inner edge of that bezel or frame was not clear, it would not allow the picture to travel through that glass to the edges of the bezel.

Please give me some information on this, if you could.

The picture of this tv (ln52a750) is incredible. I love the way the tv looks as well, but this leaking of the picture to the edges makes no sense to me.

What is Samsung's official take on this issue?????

Just looking for some official stance on this issue.

Thanks

I believe every 7 series would have this issue. The Glass that frames the actual picture is clear on the inside. Because it's clear, it transmits whatever picture is touching the edges of the screen. If you are watching something in letterbox, then it will only transmit the letterboxed portion of the picture to the top and the bottom of the tv. If you are watching widescreen, where the aspect ratio is such that you have black bars on the top and bottom of the picture, then you only get that transferrence through the sides of the bezel or glass that the bright portion of the picture is touching the edge of the screen.

The only way that the picture will not be carried out to the outer edges of that glass framing / bezel, would be if the inner portion of that glass framing was coated / treated / blacked out in some manner, that would not allow the picture to enter the glass, and of course, it would not then be able to be carried out to the edges.

The outer edge of the glass framing is bezeled at like a 45 degree angle on the back side of the glass all around the outer edge. I believe this is also why this picture transferring is visible. If the edge of the framing were, say, round, or square, I don't believe it would be so evident. That inward bezel refracts the picture that is transferred through the glass back towards the viewing angle.

So, if what you're telling me is that if I exchange this tv for another 7 series, that I would not have this problem, I'm really not thinking so. Unless I happened (and several others in various forums / reviews) to get a tv that did not have a coating or blocking mechanism of some sort on the portion of the glass framing where it comes up to the actual tv screen.

I have also read some postings where people that have called Samsung have been told that this was a design feature of the tv. Now, whether or not this is true has not been confirmed by me.

I also have not been able to find any information on the Samsung website regarding this issue.

It would have made more sense, to me, if there was some sort of ambient light transmitted through the glass framing, instead of scrolling / moving images, on a very tiny scale, mimicked on the outer edges of the tv.

Anyway, please keep this thread alive. I would really appreciate a more difinitive answer on this matter. I'm sure it would be helpful to others as well.

I personally really appreciate this Samsung forum - this link of customer service between the end user and the company. I also appreciate the time you take to answer questions and help people out.

It's just that this is a pretty high dollar purchase, and for that amount of money, you really want to be totally happy with the product, and this is taking me down to about 60%. The picture is the best I've seen, bar none. The tv is ultra sleek and very cool looking, but I'm just not sure if I can get over this distraction.

Thanks for your time.

Is there any new word on the halo effect with the 750's? I have a LN46A750 and would rather not have the halo, especially if this is a flaw for which Samsung would offer an exchange. I searched the forum here for Halo and this was the only thread I found, and the comments are from June. What more do we know about the halo in September? Was it intentional? Is it present in all 750's? Has Samsung replaced any sets because of it?

Please keep us posted. The Halo thread did slip our attention, and we are paying attention to it because at the time, it was one of the very rare occurences, but it's still important.

ave you been in contact with the repair center since?

Keep us posted.

If it's still under the return policy, I'd see if an exchange would yield better results.

I'm not aware of an official statement on behalf of Samsung.

There is no mention of this on the Canadian site, I never thought of looking at the US version.

I certainly notice the "halo", but it does not bother me enough for me to want to try to fix it on my own. The TV would likely be worse off if I tried to do that.

I'm sure the service technicians do a fine job-- I just want to wait to hear exactly what the service is (replacing the frame?) and how much of a difference it makes.

I guess that when it comes to big, expensive TVs that I love, I'm a bit risk adverse.

The rep. looked at my tv and after some phone calls he finally found out from Samsung that the solution is to replace the frame/bezel with an updated version that corrects the problem.

He said it should take two weeks for the part to come in so I'll let you know what happens.

Just had the frame/bezel replaced by the new version part#BN96-07074A.
The improvement is dramatic. There is still a very thin affect looking at a slightly outside angle in from the frame but you really have to look for it. This was done under warranty.

Short of a replacement frame with virtually no halo affect yes I am satisfied.

Either it is fixed or it is not. Yu seem to be waivering.
If light bleeding is still there ...then it was not fixed!!

There has always been just one part number not any new part number

#BN96-07074A has been lsited as the replacement Frame since the 52" 750 series was released last year. It just is not a new part#!!!

So I can't figure out how Samsung even knows what Frame they are channeling to the Service Techs and ultimately to us. 800-Samsung sure doesn't know or have a clue. The Moderators here are weak in this regard as well. Except to say that it will be repaired.

Samsung shows only one part number. There is no revised part number that differentiates new Frame vs Old Frame. Technician confirmed this. He said hit or miss. BTW it is Major surgery to disect this new Frame replacement. I personally don't care to have my 750 be a ginnea pig any longer and I myself want a replacement that had better be flawless. Some owners have felt it is intentional design. NOT SO.. It is just a distracting "light bleeding" flaw that inhibits proper Viewing in a Darkened Home Theater environment.
My MFD date is July 2008. I am tired of removing my 52" off my wall mount and remounting on its stand everytime The tech needs to try and correct this. A PIA! No tech will touch it until it is Off the Wall.

Touch Of Color is the Red, this is just a 750 design flaw. I read online that, although it looks bad, black tape around the inside of the frame can fix this issue.

I do want to know if they have a fix, as I'm getting a large Samsung LCD next week (Ironic timing) and if there is an official fix, I'll go with the 750, otherwise, I'll go with the 650. This and the cracking color are the two main reservations I have about the 7 series. There's barely any difference in price between 6 and 7 on Amazon.

Yes I contacted Samsung and got all the way up to the "Executive" level of help but as posted elsewhere they told me it was in the Design. Yes I was POed I had even threatened a class action suit. It is out of warranty so I decided to try some fixes of my own. first I just used some tape on the front to hide the halo.
Then I masked the edge about a half inch and painted the area with black paint but the tape fell off over time and the paint kind of worked but the refraction was still slightly visible . SO as I am someone who is adventuresome and mechanically incline I found out how to remove the TOC bezel and proceeded to MILL down the 45 degree clear area ( This IS the real Problem) I flattened it out and now it more resembles the 650's edge . I put it back on the TV and NOW I have The best TV out there.
Now I want to have it Calibrated , Any good Numbers to set and try? The room is mainly dark....
