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

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.

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.)
7. Upd 64083
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
then its lamp

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.

Try pressing the focus button.

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!
