Samsung LN46A650 Power ON/OFF Problems Has anyone had problems with their Samsung (LN46A650) not responding to the remote, and automatically powering off and on? Just purchased this TV 2 days ago, and when I powered it on on the 2nd day, it stopped responding to the remote, and then started powering on and off every 15 seconds. It is still in that mode now. Is there a "Restore to Factory Defaults" Option anywhere? Thoughts???

This widespread problem seem to be across all of Samsung HDTVs. A lot of owners past warranty replace blown capacitors on the set powerboard. There even a YouTube video showing how to do it.

The problem that we are having is that our TV (LNA650) takes forever to come on. The music plays and the lights flash (this morning the count was 56 times before it finally came on. We purchased it in 2008 and the problem just started) Customer service is no help--Anyone??

Well, I had the same problem. The technician came to my house and replaced the capacitors. The TV still has problem but the technician asked me for $ 95 for home visit and since it doesn't seem to be capacitor problem so Samsung will not cover it. Samsung customer service is very unfriendly and won't help with this.

yep, my Samsung HDTV LN46a50 started power cycling after the warranty expired. Looked up the issue and was *stunned* at how global this problem is and how Samsung isn't doing anything about it. Opening up mine, it indeed was the capacitors that had blown. A quick trip to radio shack for the correct capacitors for a grand $4 total (I already own a soldering iron and solder) and an hour later I had a perfectly working unit again. I will never buy another Samsung product and encourage others that I know to do the same.

Google the on/off problem, it's a well documented issue that can usually be fixed with simple firmware update. Try this thread for all things LNXXA550... www.avsforum.com/avs-vb/showthread.php?t=1020612

I just called samsung (5/6/2010) regarding the clicking on/off issue. I purchased my LN46A650 May 31 2008. I don't have an extended warranty. They said they will repair the unit free of charge ONCE if it is showing any of these symptoms:Does not turn onRepeatedly turns on/off with a clicking soundTakes long time to turn onClicks on/off w/ no picture.The repair must result in replacing the capacitors or there will be extra charge.

I purchased this TV in Jun 2008, from Amazon. LOVE the TV!! works great,...... worked great until few days ago (Sept 2011). Now, it constantly turns On and Off, for about 5 to 10 minutes. Than it stays on. I had just called Samsung, they will be happy to repair this issue at no charge. 5 star customer service.

It happened with my LN46a750 also. I purchase from Warehouse Deals for 1308 on DEC 11. Got it DEC 17. ON-OFF started on 19 JAN. Amazon is giving a full refund. I was researching the 650 hoping the On-Off problem was a 750 problem only... DOH!

I agree with Jessica.... I had mine lock up after a firmware down load and I had to sent if back to NJ for repairs. What a PIA. Also had problems with my Samsung TV right out of the box and off it went for repairs. NO MORE SAMSUNG PRODUCTS FOR ME! Check out LG or Sony instead

I purchased a refurbished one in December for about $1,200 including the shipping. When the tv arrived the power cord was not in the box. Samsung did send another one in about two weeks. Then when I got it hooked up the tv made a popping sound. The good thing is it was under warranty and it was fixed by replacing the main board. There were no cosmetic blemishes on the unit when we received it. If you don't mind having couple of possible problems, it will save some money. Other than that it is a great tv. Hope this helps with your decision.

i have the LN46C630 model with same flickering problem occuring just after warranty expired. technician fixed it by cutting one "jumper" (metal wire about 1/2 inch long) located on the power supply circuit board. takes 5 minutes to fix. technician said samsung issued service bulletin that told repair techs how to fix it. you can do it yourself with a screwdriver, small wirecutters. i could send a photo if you wantok, not sure how to post the photo here, but here's what the technician did for $150...unscrew 17 screws, remove the back cover to the TVfind the power supply circuit board, that's the one your TV's power cord plugs into. On the power supply circuit board, upper left corner, to the right of and below the large 46", there is a metal jumper labelled JP852 that is no more than 2 cm in length. it connects something labelled 'Input rating' and another labeled 'COLD'. the technician used wire cutters and cut the JP852 jumper. that solved my flickering issue, TV works great now. tech said that every size TV in this class of samsung has the same design flaw and can be fixed like this. good luck. i would post a photo, but can't figure it out."&lt;/i&gt;

I'm really interested in hearing what you found. We just got a new Samsung TV and it has the same problem.

I'm having the same problem and it's intermitent. Sometimes it works and sometimes it doesn't. When it doesn't work, I have to turn the TV on and off several times and then it will work. Then sometimes the TV just turns on by itself. We have a Samsung technician coming tomorrow to check it out - hopefully I can post the solution...

Is it normal? I don't know, probably not. Is it common? Yes - http://forums.cnet.com/7723-7596_102-269426/clicking-noise-after-powering-off-sony-kdl-40v3000-lcd-hdtv/ I have the same model and it clicks when it's off. And mine also did reboot once or twice - but nowadays everything is full of software you know, so I am not surprised - it can crash, reboot and so on. As long as it boots again everything's cool.

I have yet to buy one and think I have a couple days left to do so. I did buy one on the last TV I had and never had to use it, so it was money thrown down the drain in my opinion. That particular Television (Sony) is over 6 years old and still works like a champ. Its really up to the buyer. It is a nice thing to have in case something does happen, but in my opinion if this HDTV doesnt last me at least 3 years without any issues I wont be buying any more Samsung models. Good luck with your decision and I think you are going to like the LN32A450.

I have had my TV two days. I love everything about it except that it has this memory loss problem. I am somewhat relieved to hear others have the same issue. It means I won't bother to get a replacement. But in fact I see no alternative in the market so will probably just keep this and bear with resetting stations. I think we should all be contacting Haier, however, to assure that they fix this thing in future models

I found a partial workaround solution for my problem (like yours) of the unit turning off a few seconds after turning it on. I press (and hold) the Stop button, and then the On button, and continue to press them both until the blue SA-CD light and the blue MultiChannel light go off, and then back on again. After that, the unit works ! Except that the LCD panel remains blank. Many (perhaps all) of the front panel buttons work. I still need to experiment to see if the remote works, and to what extent. Sony gave me the choice of a refurbished unit, or to repair mine, under warranty. Anybody got an opinion on which is the way to go ?

ack.. was wondering what the heck was happening with my tv. This guy posted a video on the jumper clip fix for the 46 and 55 variants of this tv. http://www.youtube.com/watch?v=1ZwQ0gRQ9sgI'm wondering if this isolated to only the panels made in china or all panels? Assuming that the boards are manufactured from different places. I'm going to call this into Samsung just to see what happens if not I'll be trying this jumper fix.

I don't really have a good answer for you. If you look through some of the reviews on here, I think somebody has a some calibrations that you could try. Here is another set you can try from this webpage http://www.avsforum.com/t/1438531/my-samsung-un55es7100-calibration-runsdown#post_24285145 but as the forum explains, this is just a baseline since every tv is different. To have paid this much for this tv, I think mine is messed up or has issues with lighting board in it because in dark scenes, it is very noticeable in showing a flicker from either being dark or a lighter black. Samsung is supposedly going to send a tech out and look at it under warranty and hopefully they fix it and the messed up wifi issue.

Mine was turning off and then automatically turns on in few mins. Most of these problems in Samsung TVs are due to its capacitors in the power board. I dont know if your TVs issue is the same but looks like due to capacitors. I would just try this kit and it is not that hard to replace them. The kit generally has more that what is required. I just replaced all in my mother board that matched what is in the kit and it worked for me.

I also called Samsung & they referred me to a local company. They want $90 just to come out but since we can't afford to fix it right now, we have been waiting. I have read a lot of people having this issue but samsung denied it. It's a shame that a fairly new tv is having such problems. I guess that they don't make them like they use to! Let me know if you get a tech out there & the outcome. I know mine will have to wait, no job, no money.

Did you experience this crackling when you turned the TV on too? I have a Samsung 4671 and it crackles when I turn it on and off. I actually returned the first TV and the second TV crackles more, which makes me think it may not be the power supply. However, what did you have to do to remedy the problem?
