That is a good video.
Some time back I read a post on what capacitors to purchase but can not find it. Does anyone have it bookmarked so they can give it to me? I just want to pick some up to keep handy. I would hate to have it go out and then it be 2 weeks before I can make a trip out of town to buy some. The closest Fry's to me is about 75 miles.
Thanks

Any Ideas? I really don't want to have to make a disc to play in the PS3 all the time I want to watch a movie!!

As far as I know you cannot watch movies through the USB port. I believe it's really only used for firmare upgrades and viewing photos.

They do however make Digital media players (external box) that can play movies through an HDMI. I have an Argosy with a 2GB internal drive and it also takes an external USB drive if needed.

You should be able to find several different types of them online at Newegg and Zipzoomfly or even Amazon. There are a bunch of different media players that can decode the different formats and output them through an HDMI cable to the 650; just make sure it plays the format you want. Most of them can do many formats which is nice if you have a varied collection of videos.

No, you can only update firmware, play music and view pictures.
Since you have a PS3, you can just plug the HD into it and play it on the PS3. But if the PS3 can't play the file or doesn't see it, connect the HD to a computer and share it using PS3 media server.

I'm going to look into a media player but I like the bluetooth method as well.. probably save me some cash too!

Thanks again!

Come on, someone must have this info. I have tried searching but have not found the info yet.
Also does anyone know where I can download the service manual for the LN52A650?
Right now the TV is about 19 months old and still working great, I just would like to find the resources in advance.
Thanks
post #23106 of 23504
I had the same plan. Doesn't he say the cap specs in part 2 of the video? I think that's the source of the following note, which I just found on the back of a business card on my workbench under a bunch of stuff. No guarantees.

"he had 2200 microfarad 10V. Make sure to buy 105 degree C high temp. LAKE56 says 4 1000 mF 10V"

googling lake56 & capacitor produces this:

http://forums.cnet.com/5208-13973_10...sageID=3205867

And here, amazingly, is a photograph of the bad caps removed from an LN52A650. You can plainly see 1000 microF, 25V, 105 degrees C. There are 4 of them. Lower ESR is better. digikey.com is always open.

Thanks.
I downloaded the 2 videos and saved the picture of the caps. Hopefully I will not need to do this repair but just in case I like having the info.

Now if I could just find a copy of the service manual that I can download for this TV I will be all set.
post #23108 of 23504
Well I picked up a spare power supply on Ebay for $4 plus shipping. When it gets here I will check out the capacitors and replace them if they look bad. Then put it away someplace that I will remember (NOT) incase the day comes when mine fails.

I am still looking for a service manual. I found a few links way back in this thread but they are all dead now. So if anyone was able to get a copy please share......

Hello samsung gurus,
I recently had to replace my tcon board on my tv, because it went on me. But now i also need a new ribbon cable that connect from the tcon board to the lcd screen. Their are four of these cables they are about 3 or 4 inches long, one of them went bad hen replacing the board, now i have a colored strip in the middle of the tv. does anyone know where i can order these or have a part number of this cable. Its not the cable that connect from the tcon board to the other main board. They are four i think ribbon cables that connect th tcon board to the screen.

Did you try Samsungparts.com? Here is an example for one version of the LN52A650. Model search again if you have a different version:

I've got an interesting question that just came up recently. The TV itself is still working perfectly (going on two years), but Time-Warner recently upgraded their cable service in my area (well, changed) and it's affected my TV somewhat.

It now takes far longer to switch among various channels, especially if the resolution is different. Up to five or ten seconds. 1080i to 1080i is pretty fast, but, say 720 (Fox, ESPN, etc.) to 1080 is slow. Ditto for SD channels.

Does anybody have the same experience? The latest T-W interface is actually kind of cool--lots of info in the banners and the guide is better, but this slow switching is bothersome.

At first I thought maybe it was an HDMI issue with my Onkyo 606 (known problems, going in for repair soon), but the switching problem persists even on component straight out of the cable box.

Oh, yeah...I promised something interesting. I now find I'm able to maintain a picture size setting from one channel to the other.

For example, if I switch to, say, The Sopranos on A&E, the current ones they're running from the first season are stretched. So, I set the Samsung to display 3:2 and it looks fine. Now, I've done this in the past, and if you change to a true 16x9 channel, everything is squeezed. Just as you'd expect it to be.

But now all of a sudden it's not! The wide screen channel, including the info bar at the bottom will look exactly right, but when you switch back, the previous channel that had been set to 3:2 remains that way, including the squeezed info bar. Also, on the wide-screen channel, clicking the "p.size" button will show it at "Just Scan." Switch it back to the stretched channel, and it will say "3:2" just as it should.

What I don't understand is that this is setting on the TV itself, so I would expect it to be the same no matter what is being fed to it by the cable box. Plus, it only works through HDMI, not component.

So, how the heck did this happen?

I mean, I'm not really complaining, since it is very convenient. I just don't have the foggiest idea how it works. And why it took a cable upgrade to make it possible.

I swear I'm not making this up.
post #23112 of 23504
I too had this problem from my Comcast box. Here's what probably happening: Your cable box is outputting each channel in it's native resolution and aspect ratio. You probably have a mix of hi-def and standard def stations, and maybe some 720 and 1080i mix-and match. Your Samsung TV has to switch resolution and settings each time the HDMI stream changes format, hence the delay and aspect errors.

The trick is to force the box to output a constant 1080i, (or p if available). This way the box upscales lo-def to a never-changing 1080. Aspect ratio can be adjusted once and should appear correct no matter what the channel is broadcasting in.

My option to do this was buried in a hard-to-find menu (hitting menu when the box is off) Yours may differ.

My output option included 480i, 480p, 720 i and p, 1080i, or "Native" - native behaves like you say, 1080i is quick to change channel and standard def won't distort to 16:9.

(originally posted in another thread, more directly related here...)

I'm hoping there's someone out there that can give me some advice...

I had to replace 3 caps (2x 1000uf/25v, 1x 1000uf/10v) on my LN52A650 (2008?) tonight, but the only replacements I could find were 1x 1000uf/16v and big 2x 1000uf/25v, which are the same rating as the ones that burned out.

The 1000uf/25v are about 3 times the size of the originals, and I have 3 questions:

- even though the same rating, will they last longer than originals due to size?

- is mounting them on an angle a bad idea? (see pic below)

- they are closer to the heatsink behind them now, is the heatsink a factor in the early cap deaths?

The set has been working fine now for 4 hours, but I'm wondering if I should be worried about the replacement caps, their size, or their placement.

Thanks!

post #23114 of 23504
Protovision,

The bigger size doesn't say much about longevity one way or the other. The angled positions are not a problem. More heat does shorten life. You didn't mention the max temp rating of your new caps. Hopefully they're rated at 105 C. Even if they aren't it seems to me you've done all the right things and will probably be fine

As for being a little closer to the heat sink because they're bigger, that's probably not a problem either. That near the heat sink it's probably fair to approximate the heat sink as an infinite radiating wall; for that geometry received power (heat) is independent of distance from the wall. So being a little closer or farther doesn't much matter.
post #23115 of 23504
Title says it. The unit powers up spontaneously, stays on for a minute or two, and then powers off. Doesn't seem to respond to the remote while it's on. I unplugged the unit for at least a half-hour, but when I plugged it back in, it turned on by itself, and resumed cycling. In the past, the display would occasionally blank for a few seconds, and then return, but this wholesale power cycling is brand new.
Thoughts?

Thanks for the reply, all good news!

So far the tv has been working great, starts up within 5 secs, no clicking. The replacements caps are rated 105 C, so I think I'm good there.

Due to the awkward placement of the tv, I did the repair while the tv was on its stand, and the back removed, standing up (I removed the power board to do the soldering). Due to this the repair took about 60 mins total, could have been cut down to about 30 mins with a helper, longest part was taking the back off and then on.

Total parts was $20, including buying a cheap 30w iron, solder, desolder pump (not used) and 4x $.50 replacements caps.

Just scored this set used from a friend who upgraded. He had barely used it and its in like-new condition. I love it...it stands up to the stuff being sold for full price today!
post #23118 of 23504
I've been dreading this day. Had the TV for almost 2 years now. What once was an intermittent (and random) occurrence is now happening all the time (except maybe 1 in 10 uses).

The first picture shows what the TV looks like with nothing plugged into it (no hdmi, component, coax, etc.).

The second picture shows a close up of an hdmi signal and a dark background. It is hard to see but there are hints of the vertical strip.

The third picture shows the same hdmi source with colors and no indication of the stripe.

Does anyone know what this might be? It is out of warranty, so I will have to fix it myself, so any advice is greatly appreciated.

First, let me say I have LN46A650. I had the 46A550 for about 2 weeks and exchanged through Amazon. I had the HTPC hooked up via HDMI to the 550 and worked like a charm. I've hooked it up to the 650, and it seemed to work fine for the first few days. Then, intermittently, I would change to the HTPC input (HDMI 2, tried HDMI 3 as well) and the screen would be snow. Unplugging the HDMI cable and putting it back in would get rid of the snow, but inevitably the snow would return. Now, the unplugging trick doesn't even get rid of the snow. I've tried a different HDMI cable, no change. The HDMI cables work fine to run Tivo, so I don't think they are the problem. I really don't think it's anything wrong with the HTPC, as it worked fine on the 550 and works fine with a CRT monitor. Any ideas? Does this have anything to do with 120hz or AMP? When the snow disappeared, the picture looked great (colors, clarity, etc) just as it did on the 550. This is really frustrating

Thanks for any help! Tried search, but couldn't find anything similar

Having the same problem with my Samsung LN46A650. Whenever I switch to Windows Media Center the screen turns to snow. If I switch the source to something else and come back, it will reset and become normal (although sometimes I have to repeat several times). I have used several different HDMI cables. I have updated all drivers.

My HTPC has onboard HDMI out. Motherboard is a Gigabyte GA-H55M-UD2H. Have an intel i3 with 4GB ram. Running Win 7 - 64 bit.

I am wondering if this has something to do with my resolution settings in Media Center, but every time I change something, I get snow and can't get back in time to accept any changes.

Any thoughts? Thanks.

I made a post about my tv doing the vertical ine thing in the main thread. In case no one caught it. Check out these pics. What is causing this to do this? Notice on frontal moving images or text causes vertical lines to shoot up from the bottom up on each word or image being presented.

Does anyone have a copy of the service manual? The links from earlier in this thread are now dead.

TIA!
post #23122 of 23504
I've posted this before, but thought I'd try again. My TV occasionally - maybe once a day - just blacks out with no sound for several seconds. Comes back OK. If I back up with the DVR, it plays right thru, so it's not the cable. Also does it with input from the DVR (HDMI) or a DVD or streamed from Netflix.
Any thoughts?
post #23123 of 23504
I have had a similar problem. More recently, the set has gone downhill, though, with the continuous switching on and off problem. I don't know if the two are necessarily related, but after some simple tests I am pursuing a replacement of the main PCB board. If this works, and also gets rid of the occasional black-outs, that might tell us something useful...
post #23124 of 23504
I've had the LN52A650 for 18 months. It's a beautiful TV and hasn't given me any problems. However, recently the picture would go black all the sudden but I could still hear audio. It happens when watching TV and playing Xbox 360 and Wii. So I know it's not a bad HDMI cable since the Wii isn't connected thru HDMI. It happens randomly. Sometimes I can go hours without any problems but other times it will happen within minutes of watching TV or playing a game. I turn off the TV and wait a few seconds then turn it back on and the picture is fine. But if I'm watching TV for a while (watching a race or baseball game), it will happen 2-3 times. I'm outside the warranty window so I hope the set is not breaking down. Anyone else have this problem or can offer any advice. Thank you.

Does anyone know how to enable the expert adjustment in the service menu? I have a smaller model in my bedroom and it doesn't have WB or CS settings in the user menu, and I would like to do a calibration on it because I've noticed some things on it that are a bit off that I would like to take care of. I have a white balance adjustment that I can access, but the adjustment is too "coarse" and when I fix the levels that are giving me a problem it pushes the other levels out of whack. There is an "expert Grayscale" menu (which I can't access because it is grayed out) that I am hoping will give me a fine adjustment. Colorspace is also only available when expert adjustment is turned on, but the option for turning it on is grayed out too. Can anyone help me?
post #23126 of 23504
Jayspeed,

I had a similar incident with my ln46a650: sudden loss of picture one afternoon with sound persisting. I decided it might be due to the fact that I don't run the AC in the daytime and the temperature was 108 F. The TV's only rated to 104. So if you have something hot underneath it and/or there's not enough clearance around it, it might be overheating.

Since then the weather has been cooler here in Phoenix and I've had no more problems. Shouldn't be watching TV in the afternoon anyway

It did start happening in the summer and we're having a damn hot summer! Thanks for the reply. I'll see if it continues when it gets cooler out. There is plenty of airspace behind the TV and nothing hot under it. It is an oven in my house though. I usually turn the TV on when I get home from work so the AC hasn't cooled the place down much at that point.

I have wireless Pioneer surround headphones (dolby headphone) that I would like to make work with my gear. They accept a toslink or coax digital in, and like to make them work with a few of my source components.

I have a 52" Samsung LCD 650 that seems to have a toslink out, but it does not seem to work. This LCD is feed my the pioneer receiver's monitor out via HDMI. It seems to me that it should work with the digital signal send from my receiver to the LCD via HDMI.

The desire is to get it this headphones to work with several source components that connect to my receiver via HDMI and then from the receiver to the LCD.

Of course if I connect the headphones to my blue-ray directly they work fine.

I appreciate your assistance.

Does anyone know if the LN52A650 passes digital audio to it toslink out when the audio source comes from a component like a Blu-ray? The blu-ray is connected to the LCD by HDMI.
