Any ideas of things I can try on this?

Look at post 5467 above, where an owner hit the Reset and eliminated a red line. If Reset doesn't do it, read the following dozen posts after that one. They give you information about a big Samsung repair campaign. 5474 and 5475 posted by Pirates Cove refers to Samsung coverage for several problems.

Just went to Samsung support and entered my model number. They have a TV capacitor settlement notice that could help you.

Weird thing is sometimes its there and sometimes it's not.

Just for kicks, make sure your equipment and the TV are cool enough. Use a small fan to test this theory. Now that it's summer, I get an occasional video blackout when playing back from my HDDVR. I open an A/C vent nearby and direct the cool air toward the equipment cabinet (not necessarily the TV, although it's adjacent).

You could try the reset if it happens again... but it will also reset any settings you made, so write them down first. Also, go to Samsung support online, enter your model number, and look at the Alert at the top to click on the settlement paper. There have been dozens of members praising Samsung for fixing their problems or replacing with a new equivalent set. They started by calling Samsung's 800 number in the manual. Good luck. Let us know what happens.

Sorry to hear that...check the Samsung support online and their call center.

The top tier Samsung HDTVs receive excellent support, many times out warranty.

LN52A850- After almost 4 solid years, I had a weird problem recently. The set was behaving erratically. It would do things like randomly and out of the blue, switch channels, switch input, or open the menu. At first I suspected issues with the remote, or fluorescent lighting emitting stray IR. Then I noticed the touch sensitive buttons on the panel were lighting up as well when this occurred, then the lights/buttons would turn off. So, after poking around a bit, turns out, that my touch sensitive buttons were dirty?!? I mean, literally, I simply wiped the area of the buttons, and the problem went away.

Glad to hear it was just a False Alarm. wink.gif

Me too. If the remote sensor is down in that area, too, possibly that was dirty, too, and messing up the signal.

I just read an update on an A750, and that problem was a tab bond, troubleshot by "pressing against the bezel".

http://www.avsforum.com/t/1357122/samsung-ln40a750-dying-is-it-fixable



I truly hope you resolved your problem, and don't touch anything, but possibly cleaning the bezel helped temporarily fix a tab bond problem. If your problem comes back call Samsung. If you read this thread and others about "A" models, you'll see that Samsung has been good about fixing some problems out of warranty. Good luck.

Oh no...I'm getting the dreaded thin-vertical blue line on an off again.

The line about an inch from the left-side of the bezel- has only lasted a few minutes, thankfully.

I called Samsung, its out of warranty and since it was manufactured in 2009 -no capacitor coverage.

I then called Best Buy (I still have the 4 year warranty) so a Geek Squad tech. is coming out on Tue. July 31.

If they can't fix it, any recommendations for a good replacement?

If they can fix it, and if it's only a few hundred $, that might be the way to go, to hold you for a few more years. I love mine so much that's what I might do if faced with that decision. I think the lines are the TCON connectors. You might send a PM to mes444 (I believe), who knows about that stuff.

I've been following the EH6000 and bought and installed one for a friend. It has a very clear defined picture. The only complaint on AVS is viewing angle, but I don't think it's as bad as folks here say. It seems infinitely adjustable, and is 120Hz, but no SMART stuff.

The other one is the ES8000, which is what I probably would go for if I had to buy. Why not try 3D, etc. There were complaints about flashlighting and clouding on AVS, but, in general folks are happy with it. I saw a bigger one at Best Buy, and, of course, it knocked my socks off.

Let us know how it goes.

Thanks for the advice, the line appears only about 5% of the time.

I think you are right about the TCON connectors.

Between now and Tue. the 31st, I'll research possible replacement HDTVs.

I really want to keep that outstanding viewing angle.

The Best Buy warranty covers all repairs and any replacement if necessary.

Times like these I glad I still have my old Philips EDTV. smile.gif
post #5501 of 5551
Best Buy Geek Squad tech did a factory reset and concluded its a bad panel.

He put in an order for a new panel, yet said it was unlikely one was avaliable.

I really don't want to replace this HDTV...I may even look into a refurbished A850- as Best Buy still have them.

I understand that completely. Unless one's owned an A850, they wouldn't understand. I've been following the ES8000 thread and, only recently, there are complaints from a handful of members about an internal auto dimming in Movie mode that can't be defeated. There aren't a lot of clouding and flashlighting or other complaints, however.

Since the EH6000 line has a semi matte screen, I don't think there is enough pop for folks. However, there are very few complaints about anything. I helped a friend with a 40EH6000, but she was insistent on not paying a penny more for cable, so I had to re-connect her D to A converter. Heaven help me. Before I did, however, I plugged in the coax and auto-programmed, and saw some nice HD on local stations (thanks FCC). I spent an hour tuning up her set on the D to A converter and got it to look pretty good, however. The set is pretty adjustable. Next time I'm over there, I may push the backlight up a bit.

I followed some of the new LG threads for awhile, but there were a ton of complaints about advertised features not being there. The sales guy in the store and I both saw some severe pixelization in action scenes and he said it's a problem.

Since you have a warranty, maybe they'll pop for an A850. That could hold you for a few more years, when I think the market will be totally different.

Thanks for the advice..I am interested in the D630s, EH6000s ( full LED back-lit) or better yet a A850 panel or refurb.

I don't want to lose that viewing angle.....I'm weary of the ES8000s and other edge-lit LEDs uniformity (flashlighting/clouds).

Hopefully I'll find a way to get a "new" A850...wink.gif

Good News: Best Buy Geek Squad informed me that the A850's panel has been ordered and shipped.

I will track the panel and was told to call back to schedule a earlier install. smile.gif

My Tuesday (tomorrow) service appointment got pushed to Saturday the 17th.

Not too bad, the vertical line shows less than 5% of the time.
post #5508 of 5551
YEEEEESSS!!

The new panel works great and I convinced the Best Buy Tech to let me keep the non-IR Invertor Board.

The legacy of the A850 lives on. smile.gif
post #5509 of 5551
Congratulations. Is the inverter board the thing that solved the IR problem they had originally? I remember that issue, but didn't have the problem, so didn't pay too much attention.

Yes, the invertor board fixed the IR problem.

This panel has better uniformity, less flashlighting.

The panel was used and is flawless except for 2 tiny millimeter sized blemishes on the super clear panel's black coating in the bottom right corner.

During normal viewing and at a distance you can't see the minor blemishes- so its Okay.

Good, glad to hear it could be fixed. Mine will be 4 years old on Sep 13...

The saga continues...replacement panel turned out to be defective....mad.gif

Luckily the same tech came out and ordered a new (better) panel.

Unfortunately he changed a value in the service menu and now....

the menu screen has a large purple square, the info. of resoultion and time is generic grey and rectangular ...

the Weak or No Signal screen is no longer black its blue..

and the TV goes to a blue background upon power up and shut down.

Best Buy Geek Squal replaced the panel today and has ordered a replacement main board for next Saturday....

Good Grief....
post #5513 of 5551
I flashed the firmware from 1003 to fw 1002 back to fw 1003 and that fixed the blue screen problem. smile.gif

Too bad the menu screen still has the purple square and the info. (resolution/time is still) messed up. mad.gif
post #5514 of 5551
Glad to hear the screen is OK. Can't he just change the service menu back? My set is 4 years old on Sep 13th, and my fingers are crossed. I didn't buy any extended warranty.

The Main Board is coming via. UPS this week and they'll swap it out on Saturday.

A reset of the Service Menu will not restore the values that the Geek Squad tech changed (we tried twice).

The "new" screen has some 'minor' uniformity issues so it may be round 3 in the Panel Lottery. eek.gif
post #5516 of 5551
The Geek Squad Tech installed the new main board and it was locked in Calibration mode.

I returned the set and picked up a Samsung D630...and its also has a great picture and all the features....smile.gif

Glad you got it resolved. Was the A850 covered under a Best Buy warranty? What about the new set, is it covered for awhile?

I know the D630 is a nice set. I recommended and installed my father's, brother's, and brother-in-law's A630, B640, and C630.... each one with a great picture.

I got the full purchase price to use towards a new set through the Black Tie /Geek Squad -Best Buy warranty.

The D630 is great..but the A850 still has the better viewing angles.

The D630 screen is very uniform..no clouding or flashlights. The color accuracy, black levels and contrast best the A850.

Its a very different screen as the D630 is matte and not as bright. I am still considering buying a Best Buy A850 referb.

Thanks for the info. I may pick up a warranty next time. If you get another A850, will that continue on warranty?

Matte vs. glossy, a very tough decision. I think glossy screens have a better viewing angle. And, if you caught it in my last post, my brother's set is a B640 which was a B630 with glossy screen that was offered at the time. The D630's and some older Sony and LG sets with matte screens have a very nice, crisp picture, but a glossy screen just seems to pop.

Since my set is now four years and three days old, no warranty, I'm still watching the market. I notice the ES7100 and ES7500 are cheaper than the ES8000. Some folks doubt that microdimming ultimate (?) even works in Movie on the 8000, so the 7100 or 7500 would be on my short list.

No B.B. warranty this time...If I go extended warranty again it will be with Samsung.

I'm used to matte screens as the first 3 LCD HDTVs I had were matte.

Glossy looks great, matte looks more like a projected image - home theater.

The only Samsung LED with great screen uniformity is the UN55D6420 - Best Buy had one for $1399 at clearance.
