2007 Samsung HL-Txx76 Owner's Thread - Page 60

post #1771 of 1965
Well, after two years of flawless service, my 3-year-old ruined the screen of our HL-T5076. He squirted about 1/2 his Capri-Sun into the corner and lower part of the area where the screen meets the border. This led to the following artifacts:





Anyone have any idea how a repair guy would fix this? Do I need a new screen? I unscrewed the front to look at the inside of the screen, thinking I could dry it off, but the fabric interior is dry. The juice is between the plastic outer screen and the fabric.

Even if I had a warranty, it wouldn't cover this sort of incident, so I've got to pay up. I'm assuming the cost of a new screen is prohibitive and I'll end up purchasing a new set. I hope not, though!

I have a PC plugged into the HDMI3/DVI port using a DVI-to-HDMI adapter. I have the sound output of the PC plugged into the DVI audio input on the TV. I have verified that the PC is sending audio to the TV, but I cannot hear anything. It seems as if the TV is expecting HDMI audio and not the DVI-audio input. Is there a setting that will fix this?

I've ran into this problem in the past, and it seemed to go away on its own as I tinkered with settings, but I was never able to nail down the cause.

I recently swapped this PC from Linux to Windows 7 and upgraded the video card. However, the newer card has DVI ouputs only, where the old card had an HDMI out. That's when the problem cropped up again. Is there something I need to configure on the PC to "tell" the TV to expect a separate audio stream?

Thanks in advance.

im still in dire need of the cca settings for this set. the led set had a very negative effect on he color so im hoping i can get closer if someone who still visits this board can post their service menu settings. As of now im leaving my cca off, which alleviates the color problem, but not sure what im missing out on with it off.

I bought a Samsung HLT6176SX/XAA almost 2 years ago, just recently I go to turn the set on and once it is on the picture turns off after about 10 seconds but the sound still remains for about another 4 seconds, the tv makes the powering off sound and after it is off there is buzzing that is coming from the rear of the tv next to the bulb/fan/color wheel area. The tv tries to power it self on and does after a few seconds only to repeat the process. When the tv is on the lamp light is flashing on the front and when the tv shuts off the standby/temp light is flashing in red. I have talked to other people about this and seem to get different answers every time. Has anyone experienced this do I just need to replace the bulb or can it be something else? If it is the bulb where is a good place and brand to get it from?

if the lamp led and temp led are flashing the lamp door is closed improperly. also make sure the vent isnt blocked before buying a new lamp, 2 years is a short time period for a lamp.

I had never opened the door previous to this happening, when it is on the lamp is blinking and when it shuts off the standby/temp blinks and it tries to turn on, how do I know if the door is not closed properly is it not turning the switch how it should be when the door is closed?
post #1777 of 1965
The lamp ballest will buzz loudly trying to start the lamp. Should only happen if the lamp is hot (just turned off) or is bad. The lamp led flashes until the lamp starts. A bad color wheel could also buzz. The standby and lamp LEDs will blink if the door is not closed. Page 7 in the manual explains the LED codes. Sounds like either the lamp ballast or the lamp itself is bad.
post #1778 of 1965
is there anyone that still frequents this board who can access the service menu and post the cca settings?
post #1779 of 1965
I have had this tv close to four years. about three weeks ago one pixel turned green. Now there are over 30 pixels like this. Don't notice them a lot unless the background is a darker color. does this have anything to do with the color wheel? Any suggestions would be appreciated. Or is it simply time for a new tv. thanks. greg

Hello,

Of course this happens on Super Bowl Sunday. I have a 5676S. When I try to turn on the TV, it cycles 3 or 4 times, with the LED light blinking before finally all 3 lights start blinking. So, is this an indication I need a new lamp, or is it a problem with the power supply? Any help would be greatly appreciated!

I took the time to thoroughly clean my 5076 the other day and after vacuuming out as much dust as I could from the outside I blew some air through the cooling fan to try to get some of the dust off of it. Now I have artifacts on the screen that are especially noticeable when watching any sort of dark scenes. I tried reaching inside through the access hole in the back of the TV to clean the mirror on the top and the inside of the screen using the screen cleaner and cloth that are designed for the outside of the screen but it didn't help at all. I'd like to take the front screen off in the hopes that I can see where the dust landed that is causing this problem and hopefully clean it. Can someone give me some insight as to how to remove the front panel and screen? I attempted to do it by removing screws on the back of the TV around the perimeter of the screen but I didn't make much progress so I stopped before I made more problems for myself. I hope someone here can send me in the right direction.

Thanks.

John

A lot of dust settles on the lens cover in the bottom. Open the back porthole with the set turned on and you can easily see where dust and debris are. If the lens itself is dirty, you will have to remove the light engine and then remove the lens cover to access the lens. Removing the screen is a major operation, you have to remove the light engine and processor to get to a bunch of additional screws inside.
post #1783 of 1965
This is for all you people with the dust problem

http://www.avsforum.com/avs-vb/showthread.php?t=1163595

In short, DO NOT USE COMPRESSED AIR ON THE BACK OR EXTERIOR OF THE SET!!!!!!!!!!!!

it will spread it around internally and get dust within the projection chamber and convex mirror. It is NOT sealed like it should be.

Sorry but I have a differing opinion.


DO NOT OPEN THE SET WITH IT TURNED ON. You can shock or burn yourself.

See my post above. You can thoroughly clean everything with the set un-plugged

The porthole on the back opens to the cavity behind the screen only, there are no electronics in there. It's perfectly safe to open with the set on, there's not even a screw to remove. The set has to be on to see how much dirt and dust is on the glass window in the bottom that the video is projected through. Do you even own this model?

I was speaking more generally, that opening up any electronic device with it on is not a good idea.

Maybe you can open up the porthole you mentioned, but to actually do anything you need to take the projection tray out.

The dust issue is coming from the convex mirror under the polarized glass which your not going to see well through a porthole. The entire projection tray needs to come out and the polarized glass removed

and yea I do own it.

So I ahve been doing some research, but I can't find any answer. Maybe I don't know enough about DLP but.....

So my parents ahve the hlt 76 and the black bars (top&bottom) have significan blurring and bleeding of color onto them from the rest of the scree. Like if it is showing a guy with a white shirt that was "touching" a black bar, the black bar would be a light gray color in that area. At first it was ok, I thought it was cool, but now we all have LCDs and I'd prefer to not ahve it do that anymore since we all find it annoying. Is there a way to turn it off if it is a feature?
post #1788 of 1965
I just received an email from Samsung, stating there is a class action lawsuit regarding this line of DLP televisions. It covers a "shadow effect" around the border of the picture.

I just recently noticed a weird area on the top of my picture. So, may have to give them call regarding this. Thought you guys would like to know

Anymore info on suit would be great.

I have gone through all the threads and found one or two other problems like this but noone has given any help, I have the same problem (it didn't happen during the Super Bowl though.) I get it, bowing, geometry, dark spots are all huge problems but there are others that need a little help. So whats the deal? My TV shut off and sounds like it is trying to come back on but but just cycles, I too have 3 blinking lights.
post #1792 of 1965
According to the owners manual, 3 blinking lights mean the lamp need to be replaced

Thanks Jeff,
The TV came with the house when I bought it so I don't have a manual, I guess I should try and download one.
post #1794 of 1965
i have a 5676s that was bought used about a year ago it worked great for the year (little bowing but ohh well its 4 years old) it belongs to my fiances parents and they told me if i can fix it i can have it.

now the problem. my little sister in law was watching it one day this summer and shut it off when her parents got home from work it wouldnt turn back on.

there is a medium to loud humming when i turn it on after about 5 seconds the lcd that is the farthest to the right starts to blink green (i belive this indicates that the picture will show within 15 seconds it never does)

after about 30 seconds to a minute it resets and cycles through this again

any help would be apreciated as i would much rather fix a used tv and deal with a little bowing than try to buy a new one (i am only 23 so i can use a few years of hardship lol)
post #1795 of 1965
The manual says the LED furthest to the right is the lamp LED. It also says that if all 3 LED's light up you need to replace the bulb. Since you are only getting one light on its hard to tell, but I would bet its the lamp. You may want to try to find the manual online and read it over, you may uncover more info. Good luck.
post #1796 of 1965
Just wondering how everyone is doing with this TV Still, Any further on the lawsuit
post #1797 of 1965
still going strong on original lamp. had it since they came out. great set
post #1798 of 1965
I can't complain either, I have had the bowing I had it fixed but it came back. But I still like the tv.
post #1799 of 1965
Mines still awesome! Never had the bowing issue, and still on the original lamp!
Have never regretted the purchase, and I still think the picture is better than 95% of all the LCD and plasma sets I see. (And I see plenty cause I'm a cable guy!)

Hello,

I am hoping someone has a solution for the problem I am having with my dad's 5076S.

He loves the tv and so do I. I bought it for him in September 2007.

Just recently he went to turn it on and the display never came on and it started blinking the far right (lamp) indicator light.

I read the manual and there is no explanation for the far right indicator light only.

It blinks for a couple minutes then the set powers down. No audio/no video.

I ordered a genuine replacement bulb and just installed it tonight.

It is doing the same thing so it looks like the bulb is not the issue.

Can anyone give me a clue what it might be? I would really appreciate any advice you can provide.

This has been a great set and I hope it will continue to be once this gets figured out.

Please help!

Thanks for your time,

Nick
