Samsung forum: samsung plasma 850 picks up other remote signals?

well, we do live on top of a hill with houses/apt on both sides and big bay windows in the living room. I guess if/when we move and we still have this problem we can worry more about it then. I am glad, but still annoyed the case might be the tv picking up other signals. Thanks for the response!

My samsung lcd has been experiencing volume issues for about 6 months now. Either it turns up all the way and stays there or turns down all the way and stays there. It also switches from ch 3 to AV on its own. The remote is no help. Everytime i try to use it, a red light just flickers at the start button, but nothing changes.

Thanks for any help in advance its greatly appreciated

I have the 8 series plasma and love everything about it. however, as of late and worsening everyday, the sources will start switcing as if there is a ghost in the house. Obviously, thats not what it is, but it will do it as I fight to get it back onto my HDMI/Recevier source. It keeps trying to switch even while I am in control of the remote. Ive took out the batteries on all my remotes and it continues. The red light blinks on the tv indicating a remote function, not the case. I turned off the link between my Samsung Blu Ray and still does it. Samsung tech support seems to act as if its a new problem.

Any fixes yet? ITs getting worse to where it does it for an hour on start-up. Ive unplugged...nothing, Ive updated to the latest firmare 018. and still continues.

Let me know ifanyone got this resolved even as I am in the process of having tech support come to my home. One other thing that is bothering me and not sure if its a coinsidence, I have a PG&E smart meter hooked up and operating on a 900MHz wavelength. Could this be causing it as it transfers data?

samsung850,

If you're still under your warranty, call 800-SAMSUNG or set up a service through the Online Service Request form here:

http://www.samsung.com/us/support/service/request

I have no way of knowing if any of these are related unless I inspect them. They'd be able to diagnose your set.

I was searching for a fix on my Samsung model pn50b850 and came across this thread. The TV is approx 2 years old, and has done what is described above from roughly the time I bought it. It will at random change volume or source input. If ignored, it will eventually "lock up" where it changes source and then the little red light in the bottom right corner that lights when receiving input will start flashing continuously, and the TV does not accept input from either the remote or the buttons on the TV itself when this happens. The only fix has been to unplug TV and replug in. It then operates normally.

Typically, the TV will experience this issue about once every day. Enough to be annoying but not enough to justify a TV repair bill. I have moved locations with the TV, as well as had this issue while
using basic cable and Direct TV, so I suspect it is a TV issue, rather
than an issue involving the TV receiving signals from external sources as theorized above.

I will inquire through Samsung support, but if anyone has stumbled upon a cause or quick fix to this issue I would greatly appreciate reading about it.

Did fixing the "bezel" issue solve the problem?

I've had this same issue as everyone has described here. PN50B850 purchased from BestBuy in 2009, and no longer under warranty. I had the service company come out today and replace the control board. It was doing the whole "menu flashing on and off" deal. Now that the control board has been replaced, it is doing the "volume up to 100" thing.

I watched the service guy replace the control board today, and seemed very simple. How was the bezel fixed? Is this something that can be done w/ out having to pay a service tech? If it did work, what kind of parts are required? Does anyone know where I can order them?

Thanks for the bezel update - I was really hoping that might work and we all could do it as well as a fix. I will continue to monitor the thread to see if anyone ends up successfully resolving the issue. I too have called repair folks who want to swap the receiver board, but I hesitate to spend the $ and then not end up with an unsuccessfully repaired TV.

Since my past post, the service company came out again and replaced the controll board for the 2nd time (in hopes that the first replacement was faulty). Almost immediately it started acting up again. As time passes it gets worse. Early on it would only randomly malfunction and change sources. Now it happens almost immediately after turning on the TV.

The service company is coming out on Wednesday to replace the main board. As I mentioned in my earlier post, my TV is no longer under warranty. Purchased in 2009. All of these repairs are starting to add up. If this main board doesn't solve it, I may be junking the TV and buying a Vizio cheap from WalMart. This is what I get for buying a nice TV, I guess.

the tech came and changed the digital board. this did not have any effect. we determined that the touch keys on the bottom front of the tv are faulty. this is glued to the back of the bezel. we are ordering a new keypad to replace the old one. this may or may not work. the tech believes that this design is faulty. we will update once again after replacing this component.

My 2009 850 stared acting up a couple of years ago. They decided to replace the panel buttons that are just glued on under the bezel...back of tv has to come off...its a $41.00 dollar part $100 in labour. Everything was ok for about 8 months and it started changing sources and volume again...called out the tech as decided that I would use my extended warranty this time...tech came out and said we can replace the buttons again part was still $41.00 and labour. The piece in question is glued on and the tech thought it was something to do with the glue heating up and then causing the little panel too not function as it should. The panel is one piece that has the touch button and the ir sensor all in one...he said as we were going to replace the piece anyhow he would like to try something...I said go for it.
He lifted the glued part carefully up with la ittle scredriver, then clipped of the end that had the buttons leaving the ir sensor in place as its a single unit, plugged the unit back on tested to see if it would still function using the remote .....It worked. (this now means you can not control the tv from the touch buttons on the tv, which are hard to see anyhow but can still control using the remote. You also loose the red power light that flashes when it get stuck. The TV has been a perfect fix...cost me $85.00 for the call out fee and tv is working as it should....btw Samsung says that their is nothing wrong with this TV, we all know their is a design flaw and shame on Samsung for not recognizing it. I have pictures of the piece that he clipped if anyone is interested. I am sure this is now a home fix as it was a real simple process.

hi, send me your e-mail and will send you the picture.
my tv is still working perfectly.

Hi, I am experiencing the same problems and would like to see the picture of the repair (clipping the ribbon cable). This post was excellent and the pics would help greatly. Thanks in advance!

Thanks for the offer on the pictures. Please send them to hwhyte@nc.rr.com . BTW I have temporarily bulled the front bezel loose and shimmed it out with a napkin. Believe it or not the TV has worked fine since but would like to perform a more "technical repair". Thanks again!

Hi, never been on this site before but finally found other people with the same problems as I've had on my 50" Samsung plasma in the UK. tgd711 result matches all conclusions I've made so far, but worried about making irreversable changes! Please could you email pics or videos
"...of the piece that he clipped" so I can dare risking the same repair to my TV. Thank you.
