Stroboscopic flickering on Samsung LCD TV

by vazaraq - 5/10/11 11:52 PM

About a week ago my, almost a year-old, Samsung LN46C650 started flickering like a flashing strobe causing serious headaches after just a minute or so.

I called the customer support and was told it was most likely issue with the cable company as the flickering was occurring only on the HD channels. "OK" - I told myself - " let's wait and see"

Fast-forward a few days and the issue is getting worse - now I have HDMI flickering as well (along with the Diagnostic Picture mode).

I called the customer support once more and this time was told that I can solve it by switching to Movie mode (from the Standard) and lowering the brightness of the TV to 7 (from 9). That the issue would auto-magically fix itself after 2-3 weeks and everything would be dandy.

The Movie mode works, but the picture is quite dull - all other modes (Dynamic, Standard, Natural) flicker as hell.

Well, excuse me Samsung, but I didn't pay $1k for a TV to be forced into using the TV in a dull Movie mode with lowered brightness. Especially during the day when it's quite bright in the room.

So - keep on pressing Samsung into actually admitting there's an issue? Especially considering the fact that the warranty expires in 2 weeks.

If someone's interested - here's a short video of the issue:

that is your back-light bulb(s) flickering. They are florescent bulb(s) (CFL's). It could also be the inverter.. I call it the ballast.

Either way, it will not get any better and get it fixed before you are out of warranty.

Stroboscopic flickering on Samsung LCD TV

by Samsung_HD_Tech Samsung staff - 5/11/11 1:53 PM

In Reply to: Stroboscopic flickering on Samsung LCD TV by vazaraq

vazaraq,

I'm sorry to hear that you're having trouble with your LN46C650.
<div>
The first thing I would do is give yourself an additional three months of warranty on top of the Samsung warranty. Do that by registering your unit here:

Register your Samsung (click where the green star is, a little bit down the page)

Now, if you've already called in and received a transaction number, post it here and I'll see if I can get some attention on it. If you haven't, call in and attempt to get a service. If you're still not able to get assistance, ask for a transaction number and post it here. I'll see if one of the managers can review the situation.

Used online Service Requesform - We'll see what happens next

by vazaraq - 5/11/11 3:28 PM

In Reply to: Stroboscopic flickering on Samsung LCD TV by Samsung_HD_Tech Samsung staff

I already did the warranty extension (so I have theoretically 3 more months, though I'm uncertain if the warranty is the same as the original one)

The transaction number (from yesterday's call) is 2013435022 (that's the one where the CS suggested the Movie mode and waiting 2-3 weeks for the issue to "fix" itself (yeah, right).

I don't have the transaction number from my call last week, but can provide date and time of the call (if needed). That's the call where the CS put the blame on the cable company (which turned out to be false).

Just finished the online Service Request form and we'll see how it goes from there.

Thank you for your help!

Very nice (and proficient) technician came last week, replaced one of the boards in the TV and voil - fixed happy

The whole procedure took perhaps 20 minutes - less than I spent on the phone with CS trying to convince me there's nothing wrong with my TV.

Thanks HDTech! I really appreciate your help happy

katiedobuchu1,

I'm sorry to hear that you're having a problem with your TV. I don't handle service issues directly on the forum, but this may be helpful:

If you're a U.S. customer and just outside the warranty, register on the Samsung.com/support site for an additional 3 months of service. Look for the green star:

Hi Samsung Tech,

I took my chancse and registered my TV and got 3 more month warranty even though my tv is more than a year old. I took your advice to other customers and the power supply is being ordered.
Thank you so much! I can not wait until my TV is fixed!

Thanks again.

I submitted a service request 4113610919. I have been experiencing the exact same stroboscopic flickering as all of the other forum users have with my Samsung LCD TV. Thank you so much! I purchased my TV in May 2010 but given the repetitive flickering problem, I'm hoping Samsung will take care of it.

Thanks!!!!!

I have submitted it and also faxed in my request for an extension but for some reason couldn't get the ticket associated with my online Samsung account so i couldn't electronically send them the proof of purchase.

I have the same issue and would love to know what the problem is. Mine died 1 month outside of warranty (althought the problem had started about 2 months before the warranty had expired)

My ticket is:

5001426635

THANKS! I have the same model and the same problem. Does anyone know what the true root cause is?

Were you initially denied? Did one of the agents at 800-SAMSUNG assist?

Just checking before I send that up. Let me know.

stroboscopic flickeringon samsung 55 lcd tv

I bought the tv on 6/15/2010 and recently It's starting to do this exact same thing. It's sad that the tv just fell short of the warranty before failing. Is there anything that can be done?

46" Samsung LCD TV Flickering problem

by TheFees - 12/18/11 10:29 AM

In Reply to: Stroboscopic flickering on Samsung LCD TV by Samsung_HD_Tech Samsung staff

I have a 46" Samsung LCDTV Model Number LN46C670M1F and was purchased in May 2010 and it has that flickering problem. I tried joining the site as you mentioned, but I keep getting a serial number is not accurate error message, and I have checked both the model number and serial number three times and they are correct. Anyhow I recently called 800 Samsung and they gave me a ticket number as follows: 211 0512488 Can you escalate this?
I also have purchased a 55" LCD TV Samsung and that one is currently working fine, but I bought both Samsungs at the same time. I see in the Amazon reviews they are having problems with that one too. What can I do? Can you help me with the 46. I have raved about the Samsung lines as being the best for a long time. Referred my friends to them. My neighbor is having the exact same problem. Can a tech do both of them at the same time. He has the exact same TV because I raved about mine so much. I also told my best friend to buy them as well, so he bought two 46's the same TV and one 32. Does replacing the capacitors result in a long term fix? Is the replacement board the same old board and provide only a year and a half of service?
Your help is greatly appreciated. I am a firm believer in it is not whether people ever make mistakes, because we are all human, it is what we do about them that really matters. I have both of my fingers crossed that you can work some magic.
Thank you.

TheFees,
I believe this is something that can be handled by the service department. Unfortunately, I can't open service tickets publicly, but you can reach out to us here and explain your situation, and a manager will be able to review your case.

Samsung Tech--I have been having this problem on and off for the past few months. I finally used the samsung online tech support tonight and was told that my warrenty is up and that i would need to contact a service provider. Since this is a well known problem/defect is there anyway that you can help me? I bought my tv from Amazon and it was delivered to me on 5/13/10. I also tried to register my TV and the samsung site would not allow me to.

It catches up later. But try to register it again since you may get 3 more months of warranty.

sherrie2011,

I'm sorry to hear that you're having this issue with your TV.
<div>
I'll be happy to check for you.

Try calling the 800-SAMSUNG number. If they aren't able to assist with the 3 month extension (mention that on the call, and they should be able to assist, I would think!). But if they don't, then ask for a transaction number, politely end the call, and post that number here. Make sure that you give a phone number that you can be reached at if the service center calls you back during business hours.

I'll be happy to ask a manager to review the situation and see if we can help if it gets to that.

Please keep me posted.

Same flickering issue

by eflechsig - 9/18/11 2:37 PM

In Reply to: ..sherrie2011 by Samsung_HD_Tech Samsung staff

Good evening HDTech,

I'm experiencing the same issue that the other have talked about. I've registered my device for the extra 3 months warranty, however I don't believe that will help any because I purchased this TV April '10 (1 year and 4 months ago). I just spoke with support on the phone and they said that all I needed to do was update the firmware. Once I did, the issue hasn't gone away. The transaction ID is 2109106922.

I'm pretty bummed out because this TV replaced the LN46A850 that was ALSO defective. Support has been very helpful, however I'm a little discouraged with this new round of issues. Is there anything you could do for me?

Thank you an advance for your time.
