Question about Projection Televisions

Samsung HL-S5679W No video No sound

My samsung went out about a week ago. It has no audio or sound. The LED light on the front will blink in no specific order and the tv clicks on and off a few times and then stays off. All three fans work. I get all correct voltages on BP41-00268B card connectors CN100 and CN 300. I get the 115ac to card bp96-01495A.

    which board is the vertical drive

  • mark pasley Jan 30, 2009

    The led blinks 19 times clicks off then on then blinks18 times clicks on then off then blinks 17 times then it stays off and all three lights continue to flash

  • mark pasley Jan 30, 2009

    I think the power supplies are good as far as the voltages that i am reading i dont have manual or schematic.

  • mark pasley Jan 30, 2009

    how do i look at all solutions at once it doesnt let me look at them unless i repost the problem. I didnt think this tv had a lamp or ballast cause it is led.

  • mark pasley Jan 30, 2009

    do you know which transistor is the horizontal output transistor and what board it is on

  • mark pasley Feb 03, 2009

    I can take internal measurments just need to know what measurments to take

  • mark pasley Mar 10, 2009

    I had a tv repairman come out and he said the led's were bad so I replaced them and it still didnt work. Then the company said they had replace the whole led engine, so they came out and did that still didn't work. So I just troubleshot it myself. The input power was good to main power supply board but the output to the led driver power board was bad so i inspected the card and found some bad caps. I read about this in some other posts and I changed 2 caps out earlier but I missed two others that went bad. I replaced them with the same caps that were in there but i hear they need to be higher voltage. Anyone know a good cap site.

Hi..the reason for this problem may have two
possibilities,one is the problem with the
power supply and the other problem may
be due to the board inside.These are the two
problems which could have caused ur fault.
thank u..

No picture and sound, only a high pitch sound at switch on
Remove horizontal transistor and measure the resistance across any two pins. This value should be no less than 200ohms

Sorry to say, but your set is a DLP set and has no Horizontal Output Transistor. The fault could be the power supply module. The best course of action is to have a detailed estimate done. Report the results here and we can walk you through the actual repair. The problem you describe is too generic for an exact solution without taking internal measurements.

All 3 leds flash = engine error (ie lamp, ballast, colorwheel, or dmd board)
if you listen you can diagnose with just your ear...
when you turn it on, all the fans start up
then you hear the color wheel spin up (high pitched).. you will hear it come up to speed
then the ballast will fire the lamp
if you hear a short 1 second buzz sound when the lamp should fire, you have a bad lamp (even if it looks good)
if you don't hear the buzz, but hear the colorwheel, suspect the ballast..

Let me know what you hear, we can fix together, I've fixed 100 tvs with this symptom.

    This tv has no horizontal output transtor or verticle output IC. It is a DLP apparently using LED drive instead of the typical lamp and ballast (sorry). On this model all 3 LEDs blinking says "LED may be defective." Check fuses f9001 and f9002 to see if they're open, infinite ohms. If blown you need a new LED driver pcb.

    Some of these tvs give incorrect errors because of power supply capacitors. Look for bulged tops that are not flat and or black stuff coming out of the bottom. You can read the value on the side of them and buy identical uF and V values, they're called electrolytic type.

1.leave your tv UNPLUGGED overnight to do a hard reset.
2.hold power buttons for five seconds or the up and down volume buttons for 10 seconds to a light reset.
it is possible a part called the "flyback" has failed.

    The problem you are describing seems to be a Ballast issue... Does your
    TV make a clicking noise when the power is pressed? A single "strong"
    click, or multipple "weak" clicks?

    If you would like to
    replace the ballst in Your HL-S or HL-T series TV (Which includes your
    HL-S5687W) you can purchase it at the link below for only $66 bux:

    .


    When
    the TV went out, did you hear a whining or screetching noise? The HL-S
    and HL-T series lamp based projection sets are notorious for failing of
    the colorwheel... Colorwheel can be found at the below link for
    $79.99...

    I hope this helps... i don't see anything else that might be wrong with your TV other than the Lamp, ColorWheel, or Ballast...

    Please let me know the results.. It's good information for all of us here!

    One of your capacitors on the board or power supply are probably going out. It would be hard to diagnose exact problem without the proper testing equipment and repair manual.

Hi and welcome to FixYa,

Your description could indicate 2 possibilities:

  • power supply problem;
  • board/component problem.
Suggested approach would be to isolate/determine which is which. This could be accomplished by checking for the absence/presence of the voltages with and without any load/connection to the boards.

This of course would require opening the unit, perform voltage measurements,determine faulty component and subsequent part(s) replacement. Further, a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron would be required. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings.Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.

Good luck and thank you for using FixYa.

    Reference and compare voltage readings from the Service Manual.

  • Louie  Role
    Louie Role Jan 30, 2009

    Without a service manual or a schematic and comparison of voltage readings, diagnosis would be inconclusive. Though there are LED light indicators, the power supply could still be a suspect particularly the voltage doubler/tripler. Additionally, it could be failure of any of the filter capacitors, again "could be any".

    At this point, rather than looking for non-existent probable faulty component or "winging" the diagnosis, or haphazardly suspecting any, might you reconsider your options and forego DIY. Call for a qualified professional.

Hi there,

re: "It has no audio or sound. The LED light on the front will blink in nospecific order and the tv clicks on and off a few times and then staysoff."

That means that the tv is on protection mode because an internal fault had been detected.

Common faults that can cause protection are a blown capacitor or other defective component, short, lose contact or a bad voltage from PSU or convergence board.

To find the fault , you need to test the boards inside, starting from power board, if you are not an expert electronic repairer, better calling a technician.

If you have experience in repairing electronics you start by visually inspecting power board for leaking capacitors and cold solder joints.
Then you grab the service manual and follow troubleshooting diagrams with your multimeter.

Once you find the fault you can buy parts here.

You can buy service manual here.

Or training manual, that is also a training repair manual here.


If you have not used a Service manual before, better using the training manual, that is more detailed and easier to understand.

    This TV does not have a ballast, in the best case has a board that you can improperly call ballast board, that is the board that provides power to to the lamp.

    If the TV is on protection, with led blinking, but not returning any specific code, then the problem can be virtually everywhere.

    Saying it is this , or it is that will be just guessing.

    What you do in this case is visually inspecting the circuit to find a bad solder joint, or a blown component at a glance.

    When that does not work you test PSU, Convergence board, read voltages to lamp, and check for similar common faults.

    If you still get no luck you order the service manual for this model and follow the troubleshooting diagrams to finish the job.




  • Ginko
    Ginko Feb 03, 2009

    As I told you you need to perform a series of tests, as 19 blinks is not a service code, but just an erratic behaviour.

    You start testing from power board, then test ballast board, if ballast board is fine you may need to replace the lamp.

    You also need to test the DMD board.

Unplug It And Then Hold On/off For 30 Seconds Then Release And Plug It back In. When you go to power it on hold the on off button for 20 seconds or until the unit beeps. Once you've done that try to see if you get a special number of blinks.

Look for a cold solder joint in the vertical drive, as well as in the area around the low voltage power supplies, also check the inductors in the vertical drive for a cold solder joint where windings attach to pins, as well as any transistors in the vertical drive section.
See if there is a short in that area too, there may be a fuse, or fusible resistor to the vertical drive and audio stages that is shared by the two.
Also check the power handling inductors for a possible cold solder joint where the windings connect to the pins that pass through the PC board.

Check the capacitors on the power supply first. If any have domed tops or signs of leakage, replace them. I had two go bad on mine. Call electronics parts supply stores first as these are not your average capacitors.

I need to replace the bulb on my TV model # HL-S5679W. I can not locate the replacement number for the lamp. I have been unsuccessful with contacting Samsung and need help.


This model does not use a lamp----if the LED unit is bad you may want to just forget it---

Samsung part number for the entire optical engine:


BP96-01470BIt is marked as no longer available (2006 model) and had a suggested list of 495 exchange.

Google the above part number and you will find some places selling the engine---for much more than Samsung wanted.

SORRY TO GIVE YOU BAD NEWS---no replaceable lamp in this model----the LED light unit is part of the optical light engine.

all 3 leds on the front panel blinking = lamp error.
if the tv doesn't come on, it may not put sound to the speakers.
you need to focus on the error at hand.. does the tv come up and appear that it is running and not turning itself off (shutting down)?
if it runs and doesnt turn off, then the audio matters, otherwise focus on the other problems.. you won't have audio on certain inputs, etc, don't use that to troubleshoot unless your tv is running and not shutting down.
