2007 Samsung HL-Txx76 Owner's Thread - Page 59

post #1741 of 1965
Well. the repair was done and alas.......... the ghostly looking screen is STILL there and this time is worse. The 2 screens were replaced, and the problem will not go away. Samsung sent bad screens, the warranty paid for them at $ 350 and $ 200 labor. The repair center has sent over 2 weeks ago, a response that a replacement TV be issued as this issue can occur again... which would be another $350-$ 600 repair. After that we would be at $1200 in repairs and labor costs, and no guarantee the problem would be gone! Sure hope now that warranty company steps up because there is a new 52" Toshiba LCD I would love to have. I will keep you posted. Image 0448 is before repair. Image 0464 is after. That's what I call a problem......

I trying to help a friend find a part for her HLT5076SX/XAA (Ver PHO1).
She's been having the bowing problem for some time now but that doesn't bother her. Recently though she started getting black spots on the screen. Called in a Samsung repair guy who had a look inside and said its the mirror that needs changing and went on to show her that the mirror had a lot of dust settled on it.

The Samsung guy then said he would search for the part and get in touch. Problem is....he came back and said that they cant source that part anywhere !!! I couldn't believe this and asked my friend for the part number. It's a strange one...

2713100 1910 - 6103W 73CO68Y 110302E

I tried looking on samsungparts.com and partstore.com, both of which seem to have a complete list of all parts for this model.....however, no part with even a remotely similar number !!

Any advice anyone????? The TV was purchased on Amazon and never had any other problem than the bowing (and later black dots)
post #1743 of 1965
so to add to my previous post, the information found on the part (as listed on the part) is

2713100
1910-6103W
73C068Y 110302E
110302

Again, they Samsung tech guy called it a "mirror", however, there is nothing on samsungparts.com with those numbers and even the Samsung guy can't find the part. Help please anyone???

Also, I previously posted that the problem was black spots, however, I've now been told that its actually white spots on the screen. Search the forum and can't find anything about white spots on the HLT5076SX/XAA. Anyone knows anything about a problem with white spots???????

HELP PLZZZ

I have a few dust particles that have seemed to created grey spots when there is something on the screen and white spots when the screen is just black (like a non HD picture with the black bars on the side)

i was rewiring things and decided to blow out the back of the TV with compressed air and then I had two more spots on the side of the screen that I did not have before.

so I think I have dust on something that is being projected onto the screen.

does anybody know how to clean the inside of this thing or where to clean to resolve this issue without messing up the geometry (mine is good) or electrocuting myself?
post #1745 of 1965
Finally, after 7 weeks on and off the phone, the Best Buy warranty paid off and I was issued a replacement TV. This will be my last post on this forum as I have gone to Plasma and said goodbye to Samsung DLP HL-T5076S. The repair center owner told me this was the worst TV built by Samsung. I won't have to worry about a replacement bulb, ghostly screens, light tunnels, and color wheels. Do yourself a favor, if you can afford it, get another TV.... this one is bad news. Good Luck to all, I am heading to the Plasma forums!!

Have you popped open the porthole on the back? Look in there and see if you have an accumulation of dirt on top of the lens cover in the bottom. Do this with the set on to see the glass cover clearly.

Ok, so I was watching a DVD the other night and the screen would go black, I could hit the source button and scroll through till I got back to HDMI input and it would come back on and be fine for a while. Well today my wife said the TV made some strange noises and the screen went off, the TV shut down and I got two blinking lights. According to my manual it's a cooling fan malfunction. So I did a hard reset by leaving the power unplugged and then turning it back on and the screen will not light up and eventually I got the two lights, then after they'd been flashing a while all 3 lights would randomly flash indicating a bad lamp. Any ideas where to start? The tv is just barely over a year old and can't be anywhere near the 8,000 hours the lamp is rated for.
post #1748 of 1965
The repair guy came and I have something (it looked like dust to me) on the convex mirror within the projector.

It's a big bent piece of reflective material. He said it's sealed and you can't get in there. So he put everything back together and said that will be $100.

gee thanks.

Is there a way to dust that thing off that anyone knows of. It seems to me that dust in means it's not sealed. I may have to just take everything apart for myself and see if there is a way I could get a shot of compressed air in there or something.

Any suggestions?
post #1749 of 1965
does anyone have a copy of a service manual so I can see how that portion (convex mirror compartment) is put together?
post #1750 of 1965
Hello all. New member here but longtime reader.
I have had this set for almost two years now and recently noticed the left part of the picture was tilting. I adjusted a portion of the mirror as noted in post #1693, but the top left is still about 1/4 in. lower than the right. Any suggestions?
Thanks in advance.
post #1751 of 1965
The mirror adjustment only affects the bottom of the picture. To move the top portion, you can try shimming a corner of the base of the TV. This problem is common if the TV is not on a flat surface. To make further adjustments, you have to go inside and twist the whole light engine or make tilt adjustments.
post #1752 of 1965
I'm looking for suggestions for ambient lighting, I have had my TV for a while and I am really wanting to add some ambient lighting.... i have been looking for a while to find something to fill this void... any suggestions....

Thanks for the reply, Shinka. It is on a flat surface. What do you mean exactly by 'shimming a corner'? How does one make tilt adjustments?

I bought this about 15 months ago. I have noticed some things about it relative to the discussions about screen bowing. But my issue is a little different. My screen is flat. The screen is not the issue. However the bezel would give the impression of it being the screen. You see, when I tape measure from the bottom of the screen to the top edge of the bezel on the left of my TV- straight vertical- it measures 27 1/16" but on the right side same measure its 27 9/16". I have more screen showing in the vertical on the right side of my tv than on the left. This will actually make it seem like programs and/or tickers are not even, not going straight across the screen when in fact they are, it's just that your eyes are telling you that it's uneven. I don't know if there's any way to fix this issue w/o getting a whole new bezel. Further, I have noticed that a few people on here have gotten a test grid on there tv to check screen geometry. How do I do this, is there a test disc I can buy? I have the tv set where I like it but would like to officially calibrate it. By the way it is the bottom bezel that is curved. From the left where it states DLP, 1080, etc. to the right where the 3 led lights are it drops a good 1/2". Does anybody know what picture settings I should have or would be recommended?

Does anyone know if this set has any problems playing Pal content? I recently purchased my second Blu Ray player (a model which can be made region free) and I plan on ordering Martyrs from Amazon.uk soon.. However it just ocurred to me that I may run into issues in the display as this disk is pal and not ntsc. Has anyone had the chance to test the compatability of this set?

Pick up a copy of Digital video Essentials.. (available on HD DVD, Blu Ray, and DVD). That disk has several test patterns and is the best thing next to professional calibration. It has geometry tests you can use among many many other tests.

Could someone post the original service menu settings? I went in and changed my green red blue yellow and white, and lost the paper I had written the original numbers down on. Now I would like to go back to the original settings, so if anyone can take pictures of each of the menus that would be great. Thank You everyone.

Here's my screen shots I took during my Service Menu (SM) level calibration.

Hope this helps:

Check out my Tech Links below in Red for more information. I apologize that I have not kept up with my Tech Links too much... I am in Okinawa, and the TV is in Georgia, so my hobby interests have drifted elsewhere for a while...

Cheers,
Doc
post #1760 of 1965
would these settings work for the hlt5076? the service menu looks quite different, and do you know what index delay should be set at? Thank You so much for your help.
post #1761 of 1965
my main problem with my colors is it seems that any white on the screen spreads in to other colors on the image making a hazy effect. I notice it the most when watching an image with borders, and the colors can clearly be seen in the black borders. Likewise white lettering on black looks terrible because the white spreads in to the black. Does anyone know how to treat this, or is it the nature of the tv.
post #1762 of 1965
Okay so I bought this TV back in 3/2008 and the lamp promptly burnt out 6/2009. I finally got around to replacing it this past week. Like a stupid jackass, I saw dust and thought, hmm, I should blow that out. Well, guess what, I know have the lovely spots on the screen when I turn on and watch the TV. So I thought, must be coming from the lamp, removed and cleaned that, spots are still there. Hmm, I guess this is coming from the convex lens? Does that sound right? I dunno. Is this something I can clean without destroying the geometry of the set? I don't really have or want a bowing issue. Also, the set now likes to alternate the brightness every second or so...very annoying. Sorry about the long post. If you've been there and done that, please spare me a little time. I've taken off the back lower panel, where do I go from there? Thank you in advance, you are my hero (in anticipation of having my issue resolved).

This is another thread I started.

long and short. I called someone, it turned out he didn't fix it. But I did see how to take it apart when he took off the back of the TV and slide out the projection tray which holds all the guts.

It's a matter of releasing all the wires and then unscrewing four screws which hold in the polarized glass. I cleaned the glass and then slide it out to access the convex mirror.

I DID NOT move the mirror from it's mount. I just used barley any pressure with a lens cleaning cloth to dust off the mirror.

DO NOT I REPEAT DO NOT move the mirror at all.

I had no adverse effects after putting everything back together.

If you do it, take your time and don't rush.

For everybody else. DO NOT USE COMPRESSED AIR to clean the back or inside of the TV. Don't make the same mistake we did. You will not like the results and will have to take the chance I did to clean it.

in the end, it worked out and the TV is actually like new again, but I would not want to have to do that to many times.

They really should have sealed that area from dust as I thought it was source screen grain. That's what it looks like until you see how much stuff is on the convex mirror.

Once cleaned, you say "O, that's the TV I was blown away by" WAY LESS screen grain
post #1764 of 1965
Could someone please let me know if they experience the problem i mentioned above? Whites on black screens haze in to the black, which is really noticeable during credits or peoples faces on dark scenes. I just want to know if this is normal because I have a tech coming out next friday to look at it, and dont want him to say its because its a dlp.
post #1765 of 1965
just wanted to answer my own question in case anyone has similar problems. I had an issue where colors on the screen were causing a halo around objects, especially whites. The tech came and pulled out the mirror assembly and dusted it, he also cleaned the back of the screen through the port hole. The problems I had were resolved by simply cleaning the dust from those two places. Also the bulb somehow got dust in side of it, so they are sending me a new one of those also.

I am getting a intermittently slight dimming out of the lamp and think it may be time to get a new one.

Where is the best place to get a new lamp for this unit?
post #1767 of 1965
Hello,

I just replaced the lamp on my HLT56476SX Samsung and NOW my picture quality is poor. The color is NOT vibrant or vivid. It's dull or dimmed. It looks slightly blurrier than I remembered on the HD channels as well. It's very much watchable but it's by far NO where near what the picture quality was before when I brought the tv new.

Anyone know why or what I need to do now to fix it?

Thanks!
post #1768 of 1965
I tried searching through, but couldn't find it. How do you bring the grid pattern up on screen. I recently moved my TV to a new home, and now I am experiencing a bowing problem.

post #1769 of 1965
Somebody has mentioned (GarretNash?) they had replaced the color wheel in a HLT5676. For Garrett: How did you know for certain this was the problem? I have one that has the temp/standby LED flashing red after powering on for a moment (less than 30 seconds), and, while the documentation states this may be a power issue, have been told that it is likely the color wheel.

Thanks....I am aiming to fix this myself, and could use some info on the troubleshooting that led you to determine the color wheel was the culprit!

Thanks!
