2008 Samsung HL67A750 LED DLP owners thread - Page 83

Hi All, I bought the HL67A750 in Jan 09. It has been a pleasure. Not a ton
of use but consistant. I turn the set off and you hear a whine humming sound. This continues constantly. Turn it on, turn the sound off. and you will still hear the whine? Any thoughts or how to look up such a thing would help enormosly.

Thank Everyone,

If the whine eventually quits while the TV is off, then it's the intenal cooling fan. On this model tv the fan(s), I believe there are 2, are the only moving parts. The fan(s), I don't know if it's only one or both, will continue to run for a while to cool the TV down when the TV is switched off. Eventually, the fan(s) will shut themselves off.

I'd say you have a fan bearing going bad. I don't believe you need genuine Samsung replacement parts for a bad fan. Just lookup a good computer cooling fan and use it. You'll need the old fan to matchup size, voltage and current (should be on a label on the fan). As long as you don't cheap out on the fan, you could easily get a fan with much higher performance and lower noise than the original fan at about the same price. You may have to solder (or crimp) the old connector to the new fan. I'd think it would be well worth your effort to investigate. Especially, since some folks seem to be adding external USB fans to cool the TV even more.

Tyrod, Thanks so much for your reply and I will try your advice. The noise doesn't stop.
Get up in the morning, it is still going. It's been going for 3 days. If I unplug the power
strip after the tv is off will this reset all the setting to factory default?

Okay, having had to have my red LED replaced once already (so much for MTBF, reading this topic!), I picked up a 120mm USB fan to get some circulation pouring over it.

So, easy question for you folks: I'm not sure which side the LED is on. Do I mount the fan by the vents on the side closest to the USB port (right side, facing the front of the TV), or the side farthest (left, facing the front?)

Thanks in advance!

left facing front.farthest from usb port.

My 67" set has a green tint to it. If I go into the blue screen in the menu it then displays a black screen. Does that mean for sure that it is the blue LED that has failed? I want to make sure I order the correct one. Thanks

That was my problem. Didn't want to take chance on getting
wrong part so had service company do it cost about $340. If
it happens again I'll replace it myself. Replacement LED about
$100.

But how do I know which LED is the defective one? It appears to be the blue one but it seems most everyone is having to replace the red LED. I don't want to waste money on the wrong part if I can avoid that.

I would make sure that all HDMI conections are secure, then I'd try another port (HDMI 2) on the display, then try a new HDMI cable. If you are going to replace LED's I would go with all three and save the old for spares. I've never heard of blue going out, but I'm no expert!

Mine was the blue one. Displaying the test screens in the service menu
gives a black screen for the bad LED. I would guess the ones having
trouble with the red LED have the LED control turned up and are having
a heat problem. I have mine set on low and get 45FL for daytime viewing and 38FL for night with a external video processor.

Download AVS HD 709. Run the colour test patterns and see what does and doesn't display.

or throw some .jpgs of the primary colours (easily made in Paint) on a USB and plug it in to the TV see what does and does not display. (this is probably the most straightforward). If you do replace the LED's you may want the calibration disc anyways for post replacement.

if you look through the forums a technician replaced one of the leds on one of the members sets and he tested them with a nine volt battery to find the bad one.

This is perhaps the best news ever since I bought the Samsung TV. Does this mean I no longer have to get the checkerboard player like the Panasonic BDT-100 and could go for the Oppo 3D blu-ray player??

ps. just went to Mitsubishi website, it seems shipping is only possible to US for now. Has anyone managed to ship it to Canada yet?

With the adapter you can use any 3D source (or player) you want. In the 3D threads many people in the US have already gotten this kit and have not reported any problems with its use.

Well, my HL67A750 has been great since September 2008....But. looks like the day of reckoning has arrived.

When I attempt to turn it on, I know often hear the 'click' of a relay but see nothing. Sometimes I will see a slight tint of light, almost as if looking at a picture that was meant to be all black. No indicator in the upper left of the resolution, time etc.

I hit the discrete on button on my Logitech Harmony One about 10 times over a period of a minute and eventually, I'll hear that 'tone sequence' it makes when powering up and then it works fine for as long as you leave it on. If you turn it off and then back on a short while later all is fine. This problem seems to only happen when the unit is 'cold.'

I tried the original remote with the same problem.

Any ideas on the problem? Anybody estimate how much a typical in home service call costs? I assume the warranty was only one year.

SAMSUNG 67A750 DLP 3D READY
i have the panasonic DMP -BDT100 3D blu ray player
its connected to the tv via HDMI 3 renamed to PC
my 3D DLP LINK glasses are coming wednesday
on the SAMMY menu the 3D effect is still grayed out
what am i doing wrong?

If you feel up to it, download the manual, open up the back, and look around for any swollen capacitors, especially around the power supply. If you find some, just call Samsung service directly.

It will be available when you're playing a 3d disc. Sometimes, not having the display on when loading the 3d disc will not let you play in 3d.

3d menu is normally available when player is outputting 1080p/60, but goes away using 1080p/24.

At least, this is how it my HL67A750 behaves with BDT-300.

got it to work
do i pick mode 1 or mode 2?

thanks

IR glasses mode 1, DLP link glasses mode 2.

I found it rather inconvenient to have to enable 3d in Sammy whenever I play 3d disc. Seems like Sammy can detect a 3d disc is being played, and turn 3d on by picking a default mode.

I was trying to program my Harmony to do that, but couldn't find a code for MODE1.

Does anyone have a service center suggestion for the Southern California area? Samsung only refers you to Alphadtv. I feel better having some options.

It wouldn't power up this morning and I get the left most led light blinking steadily then after a few minutes of this a clicking noise followed by all three lights blinking a few times. Then it all repeats. If I had to guess I'd say it acts like its the power supply.

I haven't been here in a while but if there are DIY improvements to help make sure the repair may last longer I'm all ears (I'll be searching...).

Thanks guys,

Ok here goes. Got the 3DC-100S converter without all the glasses and emitter. Thinking my DLP link glasses that came with Monsters vs. Aliens would work. Guess what, the glasses do nothing. Are these glasses compatible? I mean, they work fine on my 8000 series Sammy LED slim LCD. How can these not work? They are samsung. I'm so damn frustrated.

Thanks

Also, I have the nvidia 3D vision kit. Is there any way to use the emitter, the glasses, anything with the 3DC-100S? The Nvidia glasses are WAY more comfortable.

Those glasses are not DLP link if they work with an LCD TV. The 2010 Samsung glasses are IR and need an emitter. The 2011 Samsung TVs use Bluetooth technology and will not work with a DLP set.

Thanks, so which glasses work 100% and will work with the 3DC-100S? I'm looking for glasses similar to the Nvidia 3D vision in shape since I wear glasses already and need the largest 3D glasses possible.

Thanks again

So, almost every single one of the glasses in that spreadsheet have an issue with the legacy dlp sets, lol.

Basically I'm SOL.

The ones that do work are discontinued. This sucks. If my Monsters vs. Aliens glasses aren't DLP or IR, what the hell are they?

Thanks

What about these?

Samsung SSG-2200AR

What transmitter? I don't want to buy the glasses and then not have them work.

Is there any way I could use my nvidia 3D vision glasses with a different transmitter with the 3DC-100S?

Thanks

The Samsung Monster vs Aliens glasses are probably IR glasses so you need an emitter. As I siad all glasses for 2010 Samsung sets including the DLP sets need the Mits emitter (or an emitter that is certified to be equivalent to the Mits emitter.

Just bought the view sonic pgd-250s. Couple of really positive reviews with my HL67A750. I think they don't work with Mitsus though.
