Question about Samsung HLN5065W 50" Rear Projection HDTV-Ready Television

8 Answers

Diagonal lines Samsung DLP HLN507

3 inch spaced dark 1" diagonal lines appear when the unit is first tuned on. Then the lines become very narrorw approx 1/4"and are almost horizontal but in the opposite slope. This is only noticed with cable - antenna mode or with dvd pluged into the 3 leg video or component inputs. When a cable box or dvd is connected to DVI input jack the picture is good. Howvever I can not adjust the picture mode. It is preset to TV(wide). I have a HD cable box and signal but the picture is not clear. The cable company checked the lines and the decible level was good. They said it may be the TV's tuner. Any suggestions of root cause ort fix?

    I have the tv cable plugged into the antenna input. I tried solution 1 with no change or message.

  • Robert Zorz Jan 06, 2009

    The only thing connected to the TV is the cable. I disconnected all the video, component and DMi cables. Same diagonal lines,almost in horizontal position about 1/4 inch apart.

  • Robert Zorz Jan 06, 2009

    How do you know that the color wheel needs replacing? What is the rational. The TV picture is fine in DMI mode but not with cable, component or DVD mode. Please advise

  • Robert Zorz Jan 06, 2009

    I am willing to replace the color wheel. I would like to know why ( the physics ) diagonal lines form from a worn color wheel and why I see a clear picture using DMi input compared to antenna, video or component input were I get a clear picture?

  • Robert Zorz Jan 06, 2009

    I adjusted contrast and sharpness setting with same diagonal lines effect/no change. Suggestion to change color wheel. Please advise

  • Robert Zorz Jan 07, 2009

    Have diagonal lines with cable connected or with cable disconnected with dvd hooked up to video input. Clear picture with cable or dvd hooked up to DMi input.

  • Robert Zorz Jan 07, 2009

    A new color wheel may be in order however why diagonal lines that flip left to right,some tighter and almost horizontal and others wider and darker shadows that are almost 45 degrees?

  • Robert Zorz Jan 11, 2009

    Changed color wheel. The lamp does not turn on.

Hi
Lamp hours are stored in the Service Menu. For the HLP5063 select "10. options" from the first page. "Lamp Life" shows the number of hours the lamp has been on.

Caution!

I would like to add to this comment ... the average owner should probably not be in the service menu. If you are an extremely careful person that has the patience to document everything before you touch anything ... than maybe. There is no reset function. If you make a change, it is changed. If you don't record your starting point and make changes you may be impacting a number of other parameters. In addition, there is a strong possiblity that your set may have unique settings ... so if you mess it up you will not be able to just ask another forum member for the answer. Some settings need to be changed is a certain order and using a process. If you are unaware of the correct procedure, you will degrade the performance of your TV. You will need to hire a professional to recalibrate your TV if you are unhappy or unsure about how it is performing.

New information for HLR owners.

BTW, it is not longer necessary to enter the Service menu to find out what firmware version you have. You can go to Function Help (pg 84 of the manual), set it to on and then press Info. Or you can get it and other diagnostic info as follows:

Mute-1-8-4-Exit will display screen 1 of Diagnostic Status
Mute-1-8-5-Exit will display screen 2 of Diagnostic Status
Mute-1-8-6-Exit will display screen 3 of Diagnostic Status

I got this directly from Samsung tech support, and it works.

htwaits: Is it possible for you to give a step-by-step 'idiot proof' protocol for going into the SM and making this gamma change? I've never been into the SM and have always been nervous about the idea. But you sound like it's worth it. (Have a 6163.) 
Can one idiot protect other idiots? ;) 

Here are the "enter-SM" instructions for the HLN sets. They are the same for a HLP set but the contents of the SM and navigation keys are different. I haven't checked all the navigation instructions myself.

Find Samsung Firmware Version:

The firmware version installed on any set is recorded on the first page of the SM. There is a long ID number at the bottom of the page. The last three digits (HLN) or last four digits (HLP) are the firmware version of your set.

Remember that in any dealing with Samsung you are not supposed to know your firmware version. 

Record your User Settings for "Picture" before you enter the SM. The HLP sets will revert to factory defaults for the UM when you exit the SM.

Instructions for accessing the Samsung Service Menu:

Anyone using these suggestions should know that the only change I have ever made to the SM is changing GAMMA from the default value to zero. I have never "messed around" in the SM. Remember that there is no reset function. If you see something that looks like one don't use it.

I can recommend, without any reservations, recording all original SM settings before making additional changes.

****** Thanks to LCH. 09/02/2003 ******

Turn Melody off in the user menu (allows entering the Service Menu from power On state without using a lamp cycle).

With the set ON, press Power-Mute-1-8-2-Power in quick succession.
(If the set is already off, just do Mute-1-8-2-Power )

The service menu should appear for the input you were viewing before keying the above sequence. Be sure to give the set enough time to complete the process(30-60 seconds).

While in the service menu, you can change inputs with the TV/Video button to view the SM for other modes. 

Use the CH up, CH down & select keys to navigate the Service Menu. Press MENU to return to the main Service Menu after viewing individual functions.

Later, you will use the VOL(+) & VOL(-) keys to change the SM values.

" ... when you access the SM on the HLPxx63 (probably all HLP models), the directional arrows around the "Enter" button control navigation, not the volume and channel buttons ..." MacGyver1970.

To Exit the SM, power off. Leave it off for several(30) seconds. (until all cooling activity is complete)

Example steps to change GAMMA on a HLP5063 with firmware version 1011 and a build date of May 2004:

The SM main menu looks like this.

1. DDP1011 (The GAMMA setting is here.)
2. GM1601
3. DNIe
4. FLI2310 
5. CXA2171
6. Vsp9437
7. Upd 64083
8. CCA
9. SP Actuator
10. OPTION (The tally of hours of lamp operation is in this menu.)

Ver: T_ATLNUS_1011 (this is the firmware version)

First record user menu entries for "picture" and enter SM.

Steps from the main SM. 

1. Select DDP1011 using the directional arrow keys -- up and down.
2. Enter DDP1011. I used the right arrow key but maybe the "enter" key will work too.
3. Select GAMMA using the up or down arrow key.
4. I entered GAMMA using the right arrow key, but the "enter" key may also work.
5. I used the right and left arrow keys to change the value of GAMMA.
6. I used the up arrow key to return to the DDP1011 menu. Again, the "enter" key or "menu" key might do the same thing.
7. I returned to the main SM with the "menu" key.
8. Power off and wait for a full shut down to save entries that you have changed in the SM.

9. Power on after about 30 seconds and enter your user menu picture settings. 

This change to GAMMA makes "some" owners happy. I feel that after setting GAMMA to zero and setting brightness with the DVE DVD that the details in dark scenes were improved. To really get the most out of our set I am getting an ISF calibration done by SethS. 

As of 12/14/2004:
Mode = Cinema
contrast = 90
brightness = 45
sharpness = 0
color = 48
Digital NR = OFF
DNIe = OFF

    My frist question: Are you experiencing the color band issue on all inputs such as DVI, VGA, Component, TV, and Video? 

    If yes, then even though this is a "controversial" answer, I would first recommend removing your colorwheel and checking for bearning wear (hard time spinning freely) or damage to one of the segments on the wheel. 

    Another problem could be a faulty/week POWER supply. BALLAST and LAMP are automatically ruled out in this situation. I would not think your DMD is bad because i'm assuming that it is producing a perfect image and the problem is not intermittent, rather consistent. 

    My free flowing thoughts: 

    1. Colorwheel (Check and with canned air first) 

    2. Power Supply or Video Input board. 

    Let us know how it goes

Do not order any color wheel, who suggested that evidently had never seen a color wheel fault .

Diagonal lines are an interference problem, or a faulty video chipset, sometimes a faulty board, like in your case a defective tuner board.
It does not look from description, but can also be a weird convergence fault.

Try first a different cable.

If the lines are only noticed with cable - antenna mode or with dvd pluged into the 3 leg video or component inputs, then a likely cause for this is a short to the main chassis, affecting the input board where the component cable and antenna hook up.

This cause the diagonal lines.

This to me sounds like a broken or possibly shattered color wheel. Here is a picture of a bad color wheel for you, so you can diagnose the problem better.

    The Repair Job

    Requirements:


    • Philips screwdriver, not too small and at least 5 inches long. There’s one screw that’s a reach.
    • Tiny (jewler’s) screwdriver. You may not need this. I needed it to get a connector off.
    • Tweezers. I needed them to get to a few screws in tight places.
    • Compressed air. I didn’t have this, but I wish I did. It’s dusty in there.
    • Pen and paper. I took copious notes. If you do anything that I don’t talk about here, you should write it down. I carefully documented every cable that I unplugged and every part I removed. Thank God I did that.
    • 1-2 hours (first time I did this, it took 90 minutes. Second time 60 minutes, with photography)
    • Nerves of steel and air conditioning. Don’t drip sweat into your television.

    Notes:


    • In this document, left and right are “stage-left” and “stage-right”, or the left and right sides of the set as you look at the back, facing your sofa.
    • Almost all of the screws are identical. You can safely keep them all in the same cup, or pile on the table, or carpet, or wherever you store the screws.
    • Don’t touch anything that looks like light will shine through it, like the projector lens or the colorwheel itself.
    • DON’T rely on this document entirely. Pay close attention and take notes or digital pictures.
    • If you were just watching your TV, your projector lamp will be HOT. Let it cool down.

    1. Remove the back panel from the television set. The panel runs the entire width of the bottom rear of the set. There’s no need to remove the access panel for the lamp. That’ll come off with the panel. There are 14 screws.


    2. Remove the projector lamp. This may be unnecessary, but (a) it let’s you see your target (the color wheel) and (b) it just seems like the safe thing to do. It’s easy. Just unscrew the two brass screws holding it in. It’s on the right side of the TV. The screws won’t come out, just pull them out with the whole unit by pulling on the handle and sliding it straight out. Carefully store it somewhere safe.



    3. Remove the panel on the left side by removing two screws holding it in place. Carefully slide it and the attached PC board out a few inches until cables stop you. You won’t actually need to remove any cables from this board to get at the color wheel. (Of course I removed most of them the first time.)



    4. Carefully note how the power cable is positioned in the set, and the route it takes out the back. Once you have done that, pull the power cord out of it’s notch in the bottom of the case. It’s blocking the next part that has to slide out.


    5. Remove the center panel. Remove the two screws in the bottom that have larger heads than the rest. You don’t need to take off the regular sized screws that fasten the back panel to the base. They’ll all slide out together. Remove the top two screws that hold the panel to the plastic case.


    Center panel. The two screws on the bottom have larger heads than the rest. Remember that these go here. There are two more screws on the bottom that hold the vertical panel to the base. No need to remove them. If you do, things get a bit floppy.

    6. Slide out the center unit slowly, just a few inches and take a peek inside as you do. It’s a snug fit, so you’ll need to ease out both the top and bottom at the same time. Some things to notice as you do this. Look at how the projector lens is fitted inside a foam sheath. You’ll need to put that back later, so take a good look.


    There are a few cables on the left side restricting it. You’ll need to unplug these:


    • blue/brown two-wire power cable. You’ll need to unplug this from the main set.
    • blue/white cable connecting to the left side. Squeeze the plug to unlatch it and remove it from the center unit that you’re removing.
    • Sensor switch on the right side. Unscrew this from the tv case bracket.

  • Jerry Parmanand Jan 06, 2009

    can i get ur email so i can send the info with pic?

  • Jerry Parmanand Jan 07, 2009

    its because your color wheel is bad that is why your getting these symptoms if you want detail instruction on how to change it yourself then i will need your email address because i try to post the info but the pics is not displaying let me know when you're ready to fix it or you can get the info from somebody else. good luck keep me posted.

I've seen this before and it's almost certainly interference in the cabling. This can be very difficult to trace down, but I'd start with the triple RCA cabling into the composite input. If that's replaced with a high-quality cable, and the problem disappears, that's probably the root cause.
Did this problem suddenly appear, or has it been slowly intensifying? In my own personal case, I saw this problem after the construction of a cellular tower near my home.
As for the TV being set to wide over the DVI connection, that is a function of the format itself. It's preprogrammed to format wide for the picture.
Try the composite-cables switchout and report back. If that doesn't solve the issue, we can tackle some other solutions.
Hope this helps!

    RFICKES Jan 07, 2009

    I'm sorry, perhaps I wasn't clear with my advice. We want to try the unit with the composite cables ONLY. The antenna cable may be the receptor for the interference. Can you try that before replacing the colour wheel and report back?

The cable box signal on the components video have a too high refresh rate frequency, that is the reason for the lines.
Use RCA cables or an alternative connection.

I've found the lines caused by the digital board before. Unfortunately it is expensive. I'd recommend running it on HD and it will bypass the faulty circuit. The lamp light flashes telling you the lamp is firing up. As the lamp ages, it will take longer and longer until it fails.

Here's the link to the user manual; http://org.downloadcenter.samsung.com/downloadfile/ContentsFile.aspx?CDSite=us&CttFileID=32370&CDCttType=UM&ModelType=C&ModelName=HCN553W&VPath=UM/200310/20031002105141187_P55A_00054A_0410.pdf Check page 28 and 29 for convergence instructions. Give it a try to see if it makes any difference. Check page 27 for the "perfect focus" feature and see if that helps. Could you take a photo of the "diagonal lines" on the set and post it - might help? If you open a menu on the screen, does it also have the lines across, or is it clear as normal. Check page 64 for how to run the demo, and try that. Have you recently unplugged the set from the mains power supply, left it for at least 15 minutes (preferably two hours) then turned it back on? if not, try it and see if you get any change. Check page 38 for the usual video settings - play around with them and see if any significant change? Check page 39 and set the "automatic picture setting" to standard, if it isn't already, and something else if it is - see if you get a change. Check page 40 for the colour tone adjustment - probably won't change anything, but worth a play in case. Check the bottom of page 46 about channel fine tuning - reset at least a couple of channels to 00, see if that makes a difference (long shot). Does the screen itself need cleaning? recommended is just a clean dry cloth - basically have a good close look at the screen when it is both on and off, to see if there are any marks that might be causing the problem - in particular has it possibly been cleaned with a solvent or too aggressively cleaned in a diagonal direction? shine a light on it at a few angles to check, and look from a few different angles too. Check by moving or turning them on and off if any other electric or electronic items near your tv may be causing the effect - speakers perhaps. Move speakers to check. A way to check other items is to totally cut off the electric supply to the whole house for a couple of minutes, except one circuit into which you can plug the TV and a picture source. See if you get a perfect picture - if so, start switching circuits back on 1 by one until it changes. Hope this helps - I think a photo would help a lot :)
