Question about Samsung HLP4663W 46" Rear Projection HDTV

1 Answer

Vertical lines My HLP4663W recently has been showing a series of vertical lines that appear over the picture (meaning you can see the picture through the lines). The pattern is 8 thin lines grouped together, followed by a space w/ no lines. There is a total of 10 line groups across the enitre width of the television. The problem arose two nights ago, disappeared for a while after having the TV off for an extended period of time, then reappeared last night. The TV is roughly 2.5 years old. From what I've read, replacing the bulb won't help. I also do not hear the "screaching" noise associated with the color wheel. Perhaps the DMD board or something else? It is no longer under warranty so any insight on cost of repair would be helpful. Thanks!

    it is all sources - cable input, DVD, and TiVo, so it is defintely the TV. Not familiar w/ wash out feature you speak of.

  • POdSmsngUsr Jan 10, 2008

    pretty sure these lines are not burned into screen as they have been coming/going the past day or two. this TV has DLP technology, not plasma. any other suggestions?

    (please try to write more clearly - your posts are very hard to read w/ no punctuation and abbreviated words...this isn't a text message...not trying to be critical, but i did pay for advice and want it to be more clear).

  • POdSmsngUsr Jan 10, 2008

    Not quite what I'm seeing. I have black/grey lines that still allow the picture to pass through. as i had mentioned, the lines have come and gone and am not hearing any noises.

    i will post a picture later.

    Thanks for your help. I brokedown and brought it to a local repair shop; he ran some diagnostics w/ the aid of Samsung Tech support and the issue "seems" to be a faulty DMD assembly (DMD = digital micromirror device; seems in "" because he nor samsung tech support are not familiar w/ the line problem we are having). Do you have any experience or thoughts? I guees the part (BP96-00678B) is roughly $600 to begin w/ never mind the labor and other costs. ARGH!

  • POdSmsngUsr Jan 16, 2008

    Believe me, i'm absolutely kicking myself for not getting an extended warranty. I have read all the problems w/ these TV's - DMD boards, color wheels, etc. - so i'm leaning toward selling for parts and buying a new set (w/ an extended warranty!!)Thanks for your help.

    My friend has a 50" Samsung DLP that is a few years old. i remember one time a group of horizontal lines appeared over the picture (this was a few months after he got). He immediately turned off and started to freak out.... but when he turned it back on they were gone.

    This is directly from samsung's website (FAQ section):

    I Have Vertical White Lines Appearing On The Screen When I Watch Video, TV, Cable And DVD.

    I Have Vertical White Lines Appearing On The Screen When I Watch Video, TV, Cable And DVD.

    If you see vertical
    lines on the screen of your DLP TV similar or identical to the pictures below, the
    circuitry controlling the vertical hold has failed, and you need to get your
    TV serviced. To arrange a service appointment, please call Samsung Customer Care at 1-800-Samsung (1-800-726-7864)
    any day between 9:00 a.m. and 9:00 p.m.
    Have your TV's model number and serial number on hand when you call.

    Is this what you are seeing?

    From what I've read it is a problem with the Light Engine Board and you will probably need that replaced.

    One owner reported, "Seems like the only way to get them to go away is to power down the
    TV and then turn it back on....changing sources amongst other things
    has no effect."

    $600 + labor is going to run you at least $700 or $800..... from what
    i've read online the early Samsung DLP's are plagued with problems....
    it might be more wise to just buy a new one (instead of paying for this
    fix and hoping nothing else breaks).

    Personally, i always buy the service plan if i buy a really expensive item like an HD TV.

    A brand new Akai 46" DLP HD TV is going for $729

    I noticed on e-bay someone is selling a used Samsung 46" DLP for $600 w/free shipping.

    A New 50" DLP w/Stand is going for $900 at and are great sites to find cheap tv's. Also check out craigslist in your town, many people sell their DLP televisions for very cheap there.

    Then sell your busted DLP on ebay (just start the auction at $0.00, put however much shipping will be, and describe what is going on with it)... someone will probably buy it for the other parts.

Have thin vertical black lines accross the screen

You have a defective optical engine. The symptom usually shows lines separated by about an inch vertically across the screen. It may be worth your time to call Samsung consumer relations and see if they will incur some of the cost.

Sony KF50WE610 Vertical Blue Lines Across Screen

the vertical blue lines indicate some interference from other electronic gadgets near your tv. it started showing up on my sony grand wega when i installed my wireless modem. i almost ordered a new rear projection lamp costing over $100 but decided to experiment. i first moved my desk computer farther away from the tv then isolated the wireless modem router by placing it inside a small glass - the vertical blue lines became lighter in color so i dedided to find another small glass that fit inside the first glass container then put the router in the double glass - no more blue lines and my wireless modem router still works.
do some deductive thinking to figure out what's messing up your tv and isolate the interference.
good luck!

Horizontal line in my TV.

"Guest" obviously has no idea what he is talking about. There is no such thing as "frame section" and if the vertical IC, ramp generator or vertical hold circuits were bad, you would have no vertical at all. If you mean that there are thin white lines at the top 3 inches of the picture, and the top of the picture seems folded back on itself, it means that the pump-up capacitor is going bad in the vertical output circuit. This is a very easy thing to correct but should be done by a qualified tech.
