post #28771 of 28850
Joined this forum today after bricking my Samsung LNT 5271 after attempted firmware "upgrade" to version 1014. I've probably done about 50 firmware upgrades in my lifetime on various devices and never, ever did the firmware cause the device to become non-functional. Just got off phone with Samsung executive consumer relations and they will be extending my warranty to cover parts for repair (they believe motherboard will need to be replaced) but will not cover the labor for replacing the motherboard. Oh well, that is better than nothing.

Has anyone figured out what the new firmware does? Why upgrade?
post #28773 of 28850
Has anyone with the power on problem changed the capacitors themselves? My friend was told his lnt4671 (2007 build) does not qualify for a replacement so I am going to change them. I would really like to know the values of the affected capacitors so I can pre buy. I've read 2200uf and 1000uf. Any others and how many of each?
post #28774 of 28850
Check the link. He discusses the type of capacitors necessary for a DIY fix:

PS: I think if your friend calls back and asks for Executive Customer service and he is in the US, he may be able to get the free fix.

Come to find out, my TV was a later build (2008) and the 1014 update was not compatible. My firmware was the 2004 firmware.

Whew! Now I can watch TV again!

I had someone on another forum ask for the instructions on un-bricking and how I found the firmware. Here is what I did:

You will need to locate this file on the net via your favorite search engine: "T-Peony_LNT@@71FX(ver 1013).exe" This firmware will get your TV back up and running.

WARNING: this is not how you should update your firmware! Use these directions only if your firmware update bricked your TV.

The newer units with the FW2004 firmware are not compatible with the latest firmware posted on the Samsung Support website since it is version FW1014. The firmware is not smart enough to prevent installing itself on the FW2004 TV's, causing the bricking of the TV. The following steps are designed to once again trick these sets into 'upgrading' to the FW2004 version from the FW1014 version posted by Samsung.

It is possible to unbrick a TV, a fw20xx set upgraded to fw1014. If this is what you have done, follow these directions to get FW2004 installed.

Its important to know that your TV now thinks it is the PEONY (not the PEONYM) so you have to trick it to look at the peonY folder instead of the peonyM folder to try and fix the issue
2) DL the f/w again so you get a clean copy and extract to a clean flash drive
3) change the name of the PEONYM folder to PEONYMBACKUP (or anything)
4) change the name of the PEONY folder to PEONYM and then change the PEONYMBACKUP folder to PEONY
5) put the thumb drive in the TV.. since you cant see the TV menu follow these instructions
-. Press Menu Button
-. Press "Up" arrow key 2 Times (Move to Set Up)
-. Press "Enter" (Select Set Up Function)
-. Press "Up" arrow key 1 Time (Move to SW Upgrade)
-. Press "Enter" (Select SW Upgrade)
-. Press "Enter" (Select USB)
==> Then automatically search new firmware (Wait around 20 sec while CPU ident FW)
-. Press "Enter" 3~5 Times for confirmation (Select & Upgrade New firmware)
-. Then wait it's upgrading until TV power off/On again automatically.


This method worked for me and resurected my bricked LN-T4069F. I hope this helps some of you who are experiencing this same issue.

Shame on Samsung for poor QC and shame on them for leaving it up on their site for so long.
post #28776 of 28850
I'm currently having a problem with my LNT-4071F hanging on an auto scan of my cable channels. It's gets to 75% when it starts to remove scrambled channels and just sits there forever. I have to manually stop the scan and then I'm left with a weird mess of channels. I've never updated the firmware and I'm not sure I want to do this since other posters have indicated that Samsung's latest firmware release (1014) has bricked their set. I have sent this question into Samsung support and have yet to receive an answer. Has anyone else in the forum had this issue?
post #28777 of 28850
Hey all, I have the LNT4071F and the speakers are blown. I did a search of this forum and didn't find the answer but I was wondering if anyone knew where I could track down replacement speakers for the tv?
post #28778 of 28850
Does anyone have a pdf version of the service manual for lnt4071f, 4671f, or 5271f?
post #28779 of 28850
All of the service manuals are available at the samsung website

here is a link for the 5271

post #28781 of 28850
Today I noticed this when I turned on my 4071.



This is how it looks when the source is plugged in from my computer.


I have tried different sources like my PS3, Xbox360 and they all look the same.

Only solution that works so far is unplugging the TV, drain the power by turn it on again, then plugging the cord back in, hit the power button to turn on.

Has anyone seen this problem or have a long term fix? I assume its not related to capacitors since its not clicking 10 times to turn on.
post #28782 of 28850
A guess. I would say a capacitor is possible since that may be a hum bar rolling through the picture. In the old days it would roll due to the 60 cycle source not being filtered by a capacitor. Just kind of looks like that to me. Don't know if it's possible with today's power supply designs.

Changed out the 2200uf caps in my friends 46" Samsung TV today with good results. Thank you all for the info.
A general question. Anyone have any reports of this being a problem with LCD TV's across the brands? Just wondering.
post #28786 of 28850
It is a problem across many brands. Check the link for an interesting overview of the capacitor problem in Wikipedia:

http://en.wikipedia.org/wiki/Capacitor_plague
post #28787 of 28850
mes444, that is really interesting. Thanks for the info. To think such a basic component can do so much harm. A lesson learned I guess.

My thought is that in Samsung's case it was also due to poor design, because it's always the same capacitors.

Having troubles with unscrupulous customer relations at Samsung that necessitated a BBB complaint. I'm dealing now with a high end customer relations man at the President's office in NJ. When he tried to find the firmware, he noted (correctly) that the firmware (version 1014) was GONE from the website. I then forwarded him the link of your screensave, which may end up saving my behind. Thank you Pizzaboy!
post #28789 of 28850
I have a Samsung Lnt4671fx that has vertical red and green/blue vertical lines. The lines are there all the time no matter is it on HD or not. I have tried to check the vertical line forum but nothing was on point. Any ideas would be greatly appreciated. I've attached a pic of the tv

Thanks,

post #28790 of 28850
I have the TV on a shelf. My son (20 months old) can just barely reach it. Not enough to do any damage to himself or the TV, but enough to turn it off with the giant power toggle that's under the screen. Any way to disable that or cover it up so it doesn't do anything when he touches it?

That's a bad LCD panel

You are welcome. I've been around the proverbial block enough times to know how these types of situations work. If you have proof, you'll get a lot more mileage than otherwise. Best of luck!

post #28793 of 28850
Has anyone had this problem? I read through the FAQ and it doesn't seem to be exactly like any of the problems described there, except maybe MBE, but from what I can tell my issue has nothing to do with the settings or non-HD content.

I'll post two pictures so you guys can see what's going on, but I want to be clear that this is not a permanent issue. It is an intermittent problem. I would says approximately every 3 or 4 days the tv starts to do this, and it will do it off and on for about 3 hours.

Any thoughts?

(Not sure where to post this... )
Hey all! Any help would be super appreciated!

Best Buy is having its Black Friday sale on the; 55" LED Samsung 1080p 120hz (UN55D6000S ) for $999.99

Currently I have a; 40" LCD Samsung 1080p 120hz (LNT4071F) (the famous origin of the TBE - I think). Bought it for ~$1,600 (boy times have changed).

Is this a good upgrade? (LED vs LCD still an issue?) Ive been hearing a ton about the flashlighting and that has me scared. But I really want a bigger TV!!! I'll mainly be using it for gaming (a lot) and bluray movies. In a nice spacious apartment, with low day light.

Please point me in the direction so I know if its worth the wait/money! Thank you!!!

Has anyone streamed Amazon Video to a LNT-xx71? It's not listed as a compatible Samsung device by Amazon. I have an iPad2. I was thinking of using an Apple iPad Dock Connector to VGA Adapter with an HDMI cable(it should mirror the iPad screen). Anybody had success doing something like?
post #28796 of 28850
Hello,
My tv LN-T5271F was covered for the 1 time cap replacement. (manufactured Dec 2007). The repair man will schedule a date.

When it started clicking I knew it was the caps. To get by til I found this thread (thank you avsforum!) without wearing out my relay, I plugged an old laptop into the vga and when I wanted the screen to go off, changed the source to pc so the tv would go to standby and still keep power to the board. My dad accidentally shut it off. When I was gone he turned it back on and let it keep clicking for 30min. yikes!
Heres my question.
Since the relay has been getting an unusual amount of wear, will the repair man replace the caps alone or the whole psu? If he replaces the caps only, if my relay goes out, how hard/much$ will it be/cost to fix?
Thanks
Joshua
post #28797 of 28850
Has anyone experienced an intermittent issue with this TV where when you turn it on it just shows a vertical rainbow stripe pattern? Not like a color test pattern, but definitely multi-colored lines running vertical across the screen. I can hear the Audio for the channel I am on, but do not get any picture other than the vertical colored lines. I do not know if it is the TV, or of it is the HDMI switching in my Onkyo 705 receiver. If I turn it all off and on sometimes it comes back up. Sometimes I have to cycle the power multiple times.


I googled some images but none really show my issue

this isn't really close to what I get, the colors i get are darker like they are the primary colors and there is a lot more black in it. Also the colors don't fill the screen like this...

post #28798 of 28850
Yes. I have the same problem with mine. It started off as four horizontal bands across the screen when first turned on. After warming up for 5-10 minutes the bands would go away and normal picture would be visible. Over a period of time, 6-8 months the situation became progressively worse and lately I had been getting an image like the one you posted which after 10-15 minutes would turn into a normal picture. I ended up getting a new TV..a Sony
post #28799 of 28850
Can someone look at their 71 series and see if there's a small border around the screen that looks to be unused pixels being used, or what looks like underscanning? No matter what picture mode I use, it's the same, it's like either they made a wrong size bezel for my screen or I have a real underscanning issue and i'm not getting my full amount of pixel usage. I tried multiple sources and every picture mode and the black border/unused underscan look remains the same. Is this normal?
post #28800 of 28850
@ Diversion

I checked my TV just now for you. I have slightly less than an 1/8" of uniform 'screen' between the edge most lit pixel and the plastic bezel. This appears intentional and not unlit pixels. This is with both 1080i and 720p broadcast material in just scan mode. I would suspect this is to allow for manufacturing tolerance to ensure they didn't cut off any pixels when placing screen to bezel?

Hope that helps...
