Official Samsung LNxxA650 Owner's Thread - Page 778

I've read through the posts, but I'm still a little unsure... so does this sound like the capacitor issue to anyone:

My TV will randomly (sometimes several times an evening, sometimes only once or twice a week) appear to power off then back on. Total time with a black screen is about 5 seconds. It basically goes black, then the resolution info window comes up in the upper left-hand corner. The red light on the front panel does flash for a few seconds while the screen is black. Maybe this is just the start of something bad...

Any advise would be greatly appreciated. I obviously don't want to call Samsung service and pay to have someone come out if this doesn't seem like it is part of the capacitor issue. Everyone else's problems seem more related to the TV not powering on or cycling on and off for 15+ minutes. Just looking for some help on a fantastic TV...

One of the early firmware versions had a problem similar to what you describe. I suggest reading the first post in this thread that talks about it and then check your firmware version.

I upgraded to the latest firmware after I noticed this issue several months ago, and no difference. But I do agree that it seems a little different from what others are indicating. It really only goes black for about 5 seconds. I can't remember if it did it with DirectTV, as I switched to Comcast cable about 5 months ago. I really don't want to take the back off and check capacitors at this point. It is annoying, but not that big a problem... yet. Time will tell, I guess.

Can anyone tell me if these Samsung LNXX650's TV use the VESA standard for wall mounts?

Thanks.

Yes, up to 52" LCDs.

Hi guys,

My Samsung LNxxA650 40" LCD recently started showing a white area on the left side of the display which gradually moves through a rainbow of reds and yellows, bleeding through about 1/3 of the screen.

After 10 or 15 minute warmup, the display magically corrects itself and looks like new. I know that the heating of the board components probably 'fixes' this issue and I am on borrowed time.

My question to the experts - is this problem worth repair? 2 year old TV bought at a big box store (May 2009). I've read about the capacitor issues, but I am not having any clicking or power flickers...only this annoying whitewash on the left margin that eventually fades to other colors, ghosts a bit and then disappears.

Image attached.

I contacted Samsung support and in the most friendly manner possible tried to arrange for 'help', but the agent insisted it was out of warranty and they would not repair. Kind of a smelly deal for a 2 year old tv to go belly up with average use for a 9 to 5 family!

Thanks for your time!

Shameless bump for one last attempt to see if anyone has any suggestions for the issue above.

Thanks again.

First, check with your credit card company to see if they tacked an additional year of warranty on the purchase. Second, if that fails open the sucker up and re-seat all of the connectors to and from the LCD panel. Chances are good that there is just a bad connection somewhere, since heat (expanding parts) changes the behavior of the display.

I called my CC help desk. Extended warranty did apply, but it expired 5 weeks ago. Bummer...

I called a local tech and he thinks it may be related to the 'T Con' board?

They charge a $50.00 look/see fee, so I'm just going forward with that to see if we can repair.

Thanks!

My fan in my 40a650 has become extremely noisy. Has anyone tried turning it off (I remember there was an option in the service menu) I know it will run hotter and shorten the TV life but just wondering if it worked for anyone for any length of time.

I have a LN46A650A1F model. Earlier this year (January) I had a Samsung tech come out and replace the board on my TV. I thought I had the clicking/reboot problem that qualified me for free, but I did not. Had to pay for him to put a new board in there. The old one had at the time the most recent firmware revision. In the last two weeks, I've had two reboots, and tonight I was playing a game on my 360, and got an error dialog on the TV that said something like "External storage not found, please check connections". Not sure what external storage it's talking about, I don't have any. I'm really hoping this isn't the start of the TV going downhill, as I just nought it in Oct of 2008, and already had to pay $300 less than 6 months ago to repair it.

Anyway, I turned the tv off, and went to see if there was a more recent firmware, if there was, I was gonna put it on there. Thing is, it's hard to tell IMO if what I have on the TV is really older or not. Heres why... I downloaded the most recent firmware on the Samsung site tonight. It's dated May 18, 2010.

When I went to my TV, the setup area says this..

MODULE: T-AMBAUSC-2008.9, DATE : PANEL : 46 A 1, MICOM : T-AMBAUSM-1005
RFS: T-AMBAUSC-20080416, 2008-10-15

When I put the USB drive in and told it to do a software upgrade, I get told this...

"Upgrade version 2008.9 to version 2007.0?"

That number seems like a downgrade, but the dates seem to imply what's on my USB drive is more recent. I don't know what to do here, samsungs site has info there saying mot to go backwards with firmware upgrades.

Can someone tell me which is really the more recent one? Tkx.

Edit: looked around the Samsung site and there's about a dozen people there asking this same question, but nobody had answered. Is it really unknown?

Edit 2: read through a lot of this thread, and it seems 2007.0 is the most recent, but there's no way to go back to 2008.9, as you can't download it. Seems stupid that Samsungs numbering system is seemingly backwards.

I went to 2007, didn't notice any degradation.

Just an FYI - I replaced my T-Con board on my a650 and it was extremely easy. The fan you are referring to would be very simple to replace. Once the back cover is off, you have unobstructed access.

Hi have had this Samsung TV (LN52A650) for a couple of years with no problems at all.I was doing some renovation in my tv room so I needed to uplug it for a while. Well it turned out to be two months. Anyway I plugged it back in and it fired right up but after ten minutes it shut off and the red light in the bottom right corner was flashing real fast. I unplugged and turned it back on and again after ten minutes it shut off on its own and the red light started flashing again. So after I turned on again it has not happened again (yet) after two hours on. From what I am reading here do I have a power supply on on its way out the door. If so I can get one online.....is it easy to replace. I do have an electrical background so I am hoping that its a simple changeout. Has anyone replaced there own Power Supply ? Thanks in advance for any tips and for helping out.

Has anyone replace the fan with this fan listed on the Samsung site? I was wondering if there are any better options out there or if a new Samsung fan will be quieter than the old one.

I actually seached for this thread to see if anyone else was having fan noise issues thinking it would be an easy solution. If it matters, I have a 40A650.

Greetings. I have an LN46A650A1F that's hooked up through an HDMI connection via my Onkyo TX-NR870 receiver with Verizon FiOS. I've noticed about 1 week ago that when I first turn the TV on (after being off for a while) that there's a blurred screen with a 2 or 3 distinct white lines in a even horizonal pattern. However, after a few minutes it resolves on it's own. Seems like I've noticed it on screens that have been auto formatted and compressed (with empty black space on left and right of TV picture)...but not positive on that part. Anyways, I'm unsure if it's an issue with the TV, receiver, cable, or the kids messed with a setting. I have a hard time believing that it won't get worse. I use a Logitech One remote to turn receiver/tv on at same time. Any help would be greatly appreciated.

Hey guys.

So i've had a Samsung 6 Series (650) TV for a few years now and all of a sudden it stopped working. I bought it brand new, and treat it very lovingly. I even have a line conditioner and surge protector attached to it. Well last night when I attempted to turn on the tv, it kept making a "clicking" noise like it was trying to turn on but couldn't. Anyone know what this may be? The only way this noise will stop is if I pull the AC cable from the power source. Even then it will still keep "clicking" until it uses every last bit of power stored (usually takes about 5-6 seconds after pulling the plug).

Anyway, I'm not sure if a resistor of some sort is blown or the power supply went bad but I'm ultra frustrated to say the least. I've only had the TV for about 2 years now. I can't believe it's dead already! So f any of you talented tech members have ideas, I'm all ears. Anything to save this TV without breaking the bank would be most appreciated. Thanks much.

You very likely have bad caps.
If you search this thread, you will find others with the same issue.

You could try calling Samsung, I know some here have reported extending the warranty because of the known issue with them using bad caps.

Otherwise, you can replace them yourself, if you have a bit of soldering skills.

The parts will run you a couple bucks, (caps are cheap).

Good Luck!

First off, thanks to all for the helpful advice gleaned over the years! Now to my question:

I have a Samsung 46a650 that has recently refused to output sound for any HDMI connection that I've tried. I have a Samsung Blu-Ray c6500 player and I can't get sound to the tv from anything on it. I thought it was the netflix app problem at first, but I can't get audio for youtube, pandora, or a disc. I also tried to hook up my computer via HDMI cable and couldn't get any audio from the tv despite setting the audio default to the HDMI connection. Otherwise, audio works fine from our cable connection (we don't have a box, just a straight connection via coax cable.) I also tried two different HDMI cables with the same results for both.

Any ideas?

Did you...

try other HDMI ports?
fiddle with audio settings in the TV?
try another HDMI cable?
Update the firmware?

I was just coming back to report that it appears to be working correctly again. Not sure why. I guess it needed a few days of vacation.

I did try two HDMI cables in two different ports. I tried to fiddle with audio settings, but didn't find much to fiddle with. Hopefully this won't happen again, but if it does I'll look for a firmware update. Thanks!

Hi, my 40a650 picture turned all green. It was a very VERY humid day (I live by the water) and then got better when the humidity dropped but there are still red sparkly dots and other artifacts on a lot of the picture. By doing some research here and google I see capacitors, Tcon board, etc. I see the majority of the capacitors on the board on the middle of the tv. Would replacing this board

http://www.samsungparts.com/Products...8A.aspx?model=

with that part possibly fix the problem? Thanks for any help; about ready to toss the thing.

I would try disassembling it and cleaning the ribbon cables with some denatured alcohol or electronics cleaner and then reassembling. Humidity usually doesn't affect ICs or other hard parts, but rather the connections between them. You can try unseating/reseating the circuit boards as well. And if that's too much hassle. I'll pay you shipping costs to send the set my way instead of chucking it!

Steve911,

My LN46A650A1F has done what you describe a couple of times since I have had it --- not nearly as often as yours does it.

I have been hoping it is due to glitches in the AC power. People in my neighborhood all run air conditioners all the time. Maybe if 2 of them kick in at the same time the 120VAC goes way down for a while. Maybe the eroding capacitors in my TV don't like that. (This is what I call hillbilly engineering --- just make stuff up :-)

I am looking for help in identifying what could be causing this problem. About 4 weeks ago the bottom 1/4 of the screen got some black lines through it, was not refreshing properly, and would occasionaly get a double image. After a few days it was 1/2 the screen, and a fewdays later it was the bottom 3/4 of the screen. It is worse on the left hand side than the right. If you look close you can see horizontal black lines across the entire screen. I replaced the T/con and still have the problem. Any help would be much appreciated.

It occurs with all equipment, all inputs, and even on a blank menu screen.

Hi all.
Been using this site for years now researching displays for myself and for friends and family. I have a 46" Sony xbr4 and a Samsung 52 a650. Its been awhile since I've checked on this thread and I just read the last 8 pages. I don't think I have a capacitor issue.

What I get is the video randomly going black (not off, just black) . Sometimes for a few second sometimes for a couple minutes. It happens on all inputs(xbox, blu ray and sat). Audio never cuts out, just picture. It's not my receiver because my xbox is going in component and my sat and blu ray are coming out of my Denon.

Any ideas? Or has this already been covered somewhere in the thread? Thanks

Greetings, everyone, and thanks to all who have posted such useful information on this thread.

After three years of completely trouble-free service, our LN52A650A1F has a minor issue: The red standby LED flickers constantly when the set is plugged in and is off. Doesn't flash--just flickers randomly. There are absolutely no other symptoms at the moment. Just wondering what this might mean and regardless, if there is a simple way to fix it--it is annoying.

Thanks in advance!

Could it be that there is some IR interference that the TV is picking up? Does it happen when the room is dark? Add any electronics in the vicinity recently?

I've got a LN46A650 and from what I read I have the capacitor issue. I've called Samsung asking only if I could purchase a new power supply and it is available. Has anyone replaced their power supply? I can't imagine it would be too difficult to do. I figure it costs enough without adding a service fee on top of it. Comments anyone?
