fyi: To anyone concerned: Samsung is replacing the power supply (or at least the caps) for free. Hopefully it will last for a few more years now.

Hello All!

I have a question regarding my LN46A650. I searched all over and I see people are having a similar issue as mine, but I haven't been able to find the root cause, therefore unwilling to spend money on parts to fix my tv.

The issue is as follows: In the past week, the tv stopped working properly. When you turn it on, there is no picture, but it has sound. The screens backlights are working. This happened very suddenly. I unplugged it for 24 hours, nothing changed. I then went to the internet. I read about how to do a hard reset and did that. I also opened it up, and looked at all the boards. I'm not a savvy guy when it comes to circuit boards, but I did learn about spotting bad capacitors from the forum. My capacitors looked fine, except for 1 thin capacitor (i'm not eve sure if it s a capacitor because it was very thin and covered by a blue insulator). The only reason why it caught my eye is because its shielding/insulator didn't cover it all the way. To better explain, it appeared to protrude out of its shielding because it was taller than the other capacitors that looked similar.

After inspecting everything and disconnecting and reconnecting all of the cables/wires, the TV started working. I read that this happens too, but I haven't seen the root cause anywhere.

Can anyone here explain what happened?

Can you post the most direct phone number that you have to the proper support team for this? My caps just went out. And here I thought I was a lucky one!
post #23346 of 23504
Looks like our 52A650 just died. Came home from work today, turned it the "system" on and the TV didn't come on. Tried it again and all it did was click. Unplugged it and it continued to click to it "lost" power. Plugged it back in, and nothing but clicking. Anyone have any ideas?

1-800-SAMSUNG, I just called on mine myself. They are aware of the issue and if you tell them what it's doing and you've "read on the forums it's the caps", they will off to do a "one time" free repair if it's out of warranty. I'm suppose to hear from the repair place next week. My only issue is ours is the ONLY TV we own right now, so until they get here and fix it............

Yeah same here, the kids have been watching netflix on my old laptop while the TV is broken. My living room has never gotten so little use!

Yeah. We watched the Blockbuster Blu-Ray and DVDs we had for Friday night on my laptop. A friend of my wife's gave us a 15" LCD TV they had laying around. So now that's are "back up" till the 52" gets fixed. Wife has to wear her glasses to watch TV now.
post #23350 of 23504
Im guessing this isnt a good sign, but last night when I turned on my LA52A650 (asian equivalent to the LN), I heard a "pop" (no smoke, no ozone smell), and then nothing. Now I cant get the set to turn on (no red light etc).

Is this a cause for major repair bill?

I really loved this TV, but it seems down for the count.

Any words of encouragement? :-)

I now need to track down a Samsung service center that knows what they are doing (not easy in the Philippines!).

Repairman came out Friday while I was at work. Was scheduled to be here between 8am-10am (so I figured they'd be there 10:30a-12:00). My wife said he showed up right after I left for work (about 7:50am), by 8:15am she was calling me saying he was done and it was working again! PS capacitors replaced was listed on the receipt he left, but my wife said he replaced the whole board. Couldn't be happier with Samsung's way of handling this, especially since it was well out of warranty!

I am moving my 46" A650 to the basement. There I will be using my Sony Blu-ray BDP S350 to play DVDs, and Blu-rays, and a Time Warner HD Cable Box. I am also using an older receiver, an Onkyo TX DS676 that does not have HDMI connections.

I want to avoid buying a new one because I just spent money for a new TV that replaced teh 650.

How can I connect these units to get the HD connections via HDMI for watching TV, and Blu-rays, yet run the sound through my older receiver that puts out good sound to my Infinity Speakers??????

Thanks in advance.......Bob.
post #23353 of 23504
I know I've asked this before, but I was told I'm just used to it. But anyone else have their AMP feature just not seem to do anything?

I have it set to high, latest firmware, and it just does not have the "pop" it once did.
Checked someone this weekend with a ln32b640, and while I realize it has more tweak options, it was quite a difference with AMP turned on.

Using a PS3 for my Bluray player, is it possible I have inadvertently changed a setting that had some effect?

Yep, I realize I'm "one of those people" who liked the AMP feature. Just really would like it to look like it once did. I'm sure I have gotten used to it in some regard, but seems I should notice it some.
post #23354 of 23504
You should be able to run stereo pairs or coax/optical from your Blu Ray player and your cable box to your receiver, and then select that stereo sound. This will run independent of the HDMI to the television, and then just turn the sound off on the television.

Measured with the an i1 Display PRO meter in ChromaPure, the best gamma setting I can get on my LN52A650 (+1) shows a serious slope from 2.5 at 5% gray scale to 2.1 at 100%. Both grey scale and CMS have already been calibrated. Black level has already been optimized and can't be used to correct the gamma without messing up the dark end of the spectrum.

Anyone know of a way to correct this (that doesn't involve a prohibitively expensive visit from a serviceman)?
post #23356 of 23504
If you have a bad cap issue and get the free one time repair, make sure you demand that they do more than just replace caps on a visual inspection basis. I got the free repair last April and the symptoms have returned this week. I e-mailed them and they more or less washed their hands of me in the reply.

They replaced the whole board on mine? Not just the bad caps.
post #23358 of 23504
Lucky you, then. I just replaced the two caps next to the two they replaced on the free one time service. Samsung is completely irrisponsible in this matter. They say they replaced all defective parts on that visit, therefore it's my dime now. A couple of cents worth of capacitors costs them wasted payroll and irritated "former" customers because they only authorized the replacement of visibly defective parts with no technical diagnosis, regardless of prior experience assuring them the other caps will fail as well. Every tech I know says the ALWAYS replace all four caps no matter how they look. I guess they were really short on time with your repair. it's much quicker to swap out the boards and I've seen them as low as $43. Hope you didn't get hastey refurb!
post #23359 of 23504
You know, now that I think about it, if I were a clever tech, and I knew how many of these same jobs I was going to be doing, I'd probably just buy myself a "starter" board as a replacement for the first job I got to, then refurb that customer's board that I just removed at my own leisure to use as a replacement on the next job and just repeat the process for every consecutive job. That would save me a lot of time on calls and earn me a reputation as the fastest "cap jobber" on the crew with the least call backs! Hmmph! Wish I'd gotten a clever tech!

Had a Question about my 2008 build LN52A650A1FZXE....

The Screen has been replaced once and the PSU has been replaced Twice within the first year that I purchased the TV being that we have frequent power outtages. TV has been fine until about 4-6 months ago. I have a verticle row of pixels that have the Red color out on it. I have a 5yr extended warranty that is good until 2013 and I was going to try and hold out to get the TV rapir under warranty until like the last month of the 5yr Ext. Warty. in the hopes that I would be able to get an upgrade being that parts would be to scarce if even available at all to repair the TV.

I'm wondering what the consensus is here for the chance that they will be repair costs will be to high for Samsung to repair the TV and thus make me elligable to get an upgrade?


(Added 12/16/2011)

EDIT: So, I just had the local Samsung repair Shop come out a look at theis TV as it had a couple of Verticle Rows of Pixels with 1 primary color out... The Tech, whom was the same guy that replaced the 2 PSU and 1 Panel on this TV the first year that I got it, said that they will most likley "Scrap the TV and give me a new one of Comparable Technology"... So he took the TV and said that I should hear from them or ABC Warehouse by next wednesday on the results of whether or not they will be fixing the unit or replacing it. he did note that he wasn't sure if I would get a new TV or if they would issue me a store credit for a new one, IF indeed I do get to replace the unit.

I would recommend something like this...

Logitech Harmony Universal Windows Media Center Remote

YOu can control your HTPC and most likely everything else that you have connectd to your HT System...

Hi all,
As many of you, I started having issues with my Samsung LCD 40".

The TV set has been working fine for the past 2 years, but since I came back from abroad after 15 days off, I am able to turn it on sporadically only.

Upon pressing the on/off switch, the TV makes the clicking noise and the intro tune, the screen kinda turns on (but is still black) and no image appears. The on/off led then starts blinking and sound works fine.

I tried to open the TV set to check for popped resistors but apparently everything is fine, which seems to rule out a power supply issue.

If you guys have any ideas I would really appreciate.

Cheers
LL

Funny thing is that a lot of people are saying that they were using a cable remote or something other than the TV's original remote. So when they replaced the batteries for the original and fired up the TV that fixed it for some reason... Not sure if that's your problem but worth a try. others said that they had a stuck button on their remote. And some had to replace the mainboard and/or PSU...

Good luck!

Need some advice on my LN52A650. In September 2010, I packed mine away for storage while I was deployed overseas. It was stored in the original packaging in my parents dry, climate controlled basement. I returned home (Ohio) this past September and just recently made a move into my new place out in Colorado Springs. The set worked perfectly when I boxed it up in September 2010, but when I hooked it back up for the first time earlier this week, I was getting a row of blue pixels in the far left side of the screen as well as some blue artifacts randomly throughout the picture. After a couple of days, the blue line remained but the artifacts were clearing up quite a bit. Last night I came home from work and there were green artifacts all covering most of the screen and severely degraded the picture. They cleared up a bit after the screen had been on for about an hour. Tonight I came home from work and immediately turned it on and let it run for ~2 hours while I worked on other stuff. I just went out to check on it and it is worse than last night.

Does anyone have any ideas on if this is fixable or is it going to have to get pitched? I really don't feel like dropping $1500-2000 on a new TV at the moment. I am going to do some more searching through this thread, but 779 pages is a lot to sort through, even with using the search function.

Well first and Foremost... THANK YOU for serving our Country!!!! And

WELCOME HOME Bud!!!!!!!!!!!!!!!!!!!!!

Now, I wouldn't pitch it by any means. yet at least. Everything is repairable! What that is caused by is the question and how plausable would it be to fix it?

You can get a Nice 55inch 120hz processing LCD now for around or less than $1000 but you could also get a 55in LED LCD for around $1200-$1500

If that is still over your budget, I think that it has something to do with graphics processor on the Mainboard. Normally Artifacting of that nature and severity is from Software issues, being that it's so Uniform to the picture and not Randomly spread throughout the screen which would indicate hardware.

I would call Samsung and See what they are willing to do and go from there... If it's giong to caost you an arm and a leg to fix, then Iw ould save the oney and go for a new one. Liek I said a 120hz LCD that is 55in will be less than the LED LCD's currently on the market.

Thanks for your help! Long story short....it is working great now! After a little time spent on Google and finding some other people with similar issues, I narrowed it down to a couple of issues, the easiest being a faulty connection between the LVDS cable and the TCON board. I popped the back off of the TV this morning and cleaned and re-secured the two connections, powered it up, and it is once again crystal clear. I guess just all of the moving and jostling around slightly loosened the connection. I couldn't be happier that it was an easy, and most importantly free, fix.

Awesome! I LOVE those types of repairs. They Make life so much more enjoyable and Bright!

Thanks for posting back on the repair as it might help someone else in the future.

Take care!

That was very Cool BearcatRR.

I have the same set, LN52A650 but having a minor issue that's bothered me for a couple years now.

IR Interference.

I have the Niles IR infrared receiver surface mount microsensor MS 210 connected to MSU250 infrared remote control extender.
Controller mounted at HT Rack.

The RXV3900 HT system, & Rack runs 2 full sound systems, and 2 Samsung's.
The office, and second system in the Monster Garage.
Small room between office & shop is where HT system rack is located totally out of general view for remotes.

Sensors from Niles just sneaks into the office at top edge of doorway, about 5' from TV at that wall / doorway.
Second sensor in the shop, and miracle compared to how I used to do this.

I didn't realize this IR Interference has been a huge issue with other members for the last 3-4 years
with the larger screens from searching this issue for the last few hours here.

Noticed also, Brands are not necessary specific to the problem.
Some stated using masking tape to lenses from sunglasses placed over sensors. Warmup time was not a factor.

This is what I discovered to finally kill or lessen this Interference from endless testing.

One thing noticed, when Niles Sensor is lit solid and now locked out from making any choice from remote,
seems more so when selecting different menus on the Tv, to scrolling news at edge of screen to some commercials.
Moving the sensor slightly out of the room brought it back to normal,
but returned at edge of doorway.

The office is generally dimly light from windows with only desk lamps mainly for computer work.

I decided to explore the Tv's screen settings.
Soon as I lowered the brightness slightly, to my amazement, problem finally went away as the solid lit LED went out on the Niles sensor.

So if you have this issue, give this easy step a try.
Not sure, but what if foil was applied to inside of rear cover?
Lowering the brightness must lower the voltage I suspect, so this must be a shielding issue.

Viewing & sensor is fine now with lower brightness setting using any device, Playstation to DVD/Blueray, to Yamaha's Menu.

The 52" is always covered with a fleece blanket when I leave to keep
dust under control & protect accidental hits to the screen walking by.
The 36" in the shop is on 24/7, mounted on swivel at edge of ceiling above doorway and never a problem.

Also, being all I have is Mac systems, I haven't been able to take advantage of the updates for the sets.
Maybe someone can advise if necessary, as no other issues are known.

Cheers

I have had a Samsung LN52A650A1FXZA TV for 3 years and have been very happy. I just decided to dump my 30 year-old receiver and bought a Pioneer VSX-821-K. I connected my Cable Box/DVR, a Roku box and a BlueRay player via HDMI to the Pioneer Receiver, then ran an HDMI cable out from the receiver to the Samsung TV.

Periodically, sometimes not for 20 mins, my screen goes black for about 2 seconds. Most of the time the audio remains. Sometimes this happens more frequently.

I tried switching HDMI cables and switching input jacks in the receiver and TV to no avail. Any ideas?
