I own a 67" Samsung HL67A750, 1080p LED LCD projection TV. It has been great aside from two issues:

1.) one of my HDMI ports looks like the old scrambled cable channels, all fuzzy and crappy and distinctly green. I don't really care too much. Swapping an HDMI cable isn't going to kill me.

2.) The real problem: The screen appears to do this flickering thing when using HDMI (read: all the time. TV/PS3/PC are all HDMI). Like picture a nice bright vivid picture, and then imagine the entire screen at once going duller, more yellow, less vivid. It stays that way for a few seconds then goes back. This happens off and on and I don't know what to do about it.

The TV is out of warranty unfortunately. Is there any chance this could be a setting in the TV somewhere or a firmware issue?

Any help you could provide would be great, I feel like this has rendered the TV near unwatchable.

Sounds like your main input board is bad. It is not the main board... the service manual shows it is a separate PCB that can be replaced fairly easily.

I donno the cost of replacement, but it should be decent over a mother board.

Actually the new models suck... thinner has a major disadvantage. The image is warped by the process. Though it is a nice rigid chasis with glass screen. ) More or less eye candy when seeing one on display.

I have 3 TV's..Sony xbr960,Sony xbr970 and the Samsung HL67A750, so bying a 3D set is out of the question for now.(i just cant give up on my CRT's) and my wife will probably kill me.....

thanks,

I have the 67a750 and it is a great set. I'm pairing it with the 1st gen Panny 3d blu-ray player that does internal checkerboard conversion. For glasses I'm using dlp link Expand 102's. Just be sure to name the 3d input on the 67a750 to PC...helps a ton with the picture when watching 3d.

As good as my67a750 is...I just bought a Mit's 73838 to replace it so I can do 3d through my gaming consoles and directv. From what I've seen the Mit's should equal or exceed the Sammy in picture quality...can't wait. It does suck about the bulbs but I'm used to it...I run front projectors in my main theater. I can live with changing bulbs every few years when they're only $99...wish my JVC RS1 bulbs were that cheap .

Edit:
Before someone says I should've just flashed the set for 3d gaming etc...I'm not getting rid of the Sammy...it's replacing a smaller set also.
post #2405 of 2719
From what I have read on another thread and confirmed from a friend that contacted Samsung (Korea), Samsung will in the next several months be putting out a firmware update to allow the Mits 3D adapter to work with the Samsung 3D capable DLP sets. With this update you will have all the functionality of the new Mits 3D DLP TVs.

What early Panasonic models come with the internal checkerboard generation? Is this the easiest and cheapest way to get 3D on the a750?
post #2407 of 2719
Currently all the Panasonic 3D players do checkerboard (100,105,107,300,350).

Jack,

Mines the bdt300 mentioned elsewhere in the thread...I was thinking I read that it's no longer being made...i haven't followed bd players much lately though.

It's pretty much plug and play with the Panny bd player and a750...especially with the dlp link glasses(no emitters). All you have to do is tell the Panny player to output checkerboard in the players setup menu. Then on the a750 be sure to name or rename the 3d input as PC(for best picture quality) and then your pretty much good to go.

That's good news on a possible firmware update from Sammy...glad I'm keeping my a750. I'll have two outstanding 3d sets.

Though for gaming and satellite to use now I got tired of waiting for Sammy to figure out a way to get non checkerboard signals to work. That's the main reason I jumped on a deal for the Mits 73838. Whether you like Mit's or not they at least came through for their legacy 3d set owners in a timely fashion.

I already have the set,what i am concerned with is not being able to convert 2D Bluray to 3D

AFAIK this can only be done on a computer. For the home user anyway.

Save your money but spend it on something else. I own both an HL67A750 and an L75A91. All that razz ma tazz about increased colors is a load of crap. All it does is oversaturate the hell out of the colors - 'think' all the reds on every NASCAR race car look the same. The following CIE chart is a comparison of the LaserVue out of the box Cinema and Brilliant modes. The arrows point to the Brilliant color points and it's really obnoxious and unwatchable.

Attachment 191433

Not only that, for calibration, Mitsubishi has cheaped out. The grayscale is only two point and the CMS (color management system) is clunky at best. Furthermore, because of the laser light source, it takes a $10-20k spectroradiometer to measure accurately. If you're going to have it professionally calibrated get out your check book because the few calibrators who use a meter of that quality need to pay for it. LOL

I get around the LaserVue's shortcomings with a DVDO iScan Duo video processor with full CMS abilities. Readings are with a Chroma 5 colorimeter profiled against my i1Pro spectroradiometer. Even though I know that the reads aren't quite as accurate as they could be, the resulting picture is amazing but I can do the same thing with a non-laser display.

Attachment 191434

My point is that you can get the same picture more easily by purchasing a Mits bulb DLP instead of the Laser and save yourself $2-3k in the process.

I'll believe it when I see it.

Prolly a alignment issue... you will need to use the service menu and toggle through the test screens to get to the grid.

Once there you will need to adjust the alignment by using the screws shown in the service menu.

It very difficult to do by yourself unless you have a large mirror and enough pace between the tv and mirror. It is easier with two people as once you got the grid aligned the adjustment can be done precisely in small increments.

Again the service manual shows the location for adjustment.

Hey guys,

I have had my Samsung HL67A750 since the beginning of 2009. Love the picture quality and clarity but recently I have started to run into a little bit of trouble.

Randomly at times, the screen will completely go blank and "shut off" and I would still hear the sound (programming would be running just fine). I would need to turn off the TV and turn it back on. When i turn it back off, it seems like the screen struggles to boot back up, but when it does, everything is back to normal.

Can anyone chime in on what might be wrong? A weak capacitor / a solder joint coming loose somewhere?

Thank you,
Calvin

I'm getting that on hdmi 3. Like it can't sync up to the picture.

Ports 1 and 2 are fine though.

Try your other HDMI ports.
post #2418 of 2719
I've had my 67a750 (1007.4) since March of 2009 but today the display started dimming, every few seconds it would dim a noticeable amount more. I turned it off after probably 20 seconds, let it rest for a minute then turned it back on. It came on but now there is no red. No red on any input (HDMI, AIR or composite) or even in the menu. Any ideas on what needs to be replaced and how hard is it to do?
post #2419 of 2719
WAG would say the red LED. No real idea, though.

just got the optoma 3d glasses for 90 bucks a pair and the panasonic bdt-100 for $150.Both on Amazon. Had to check every day to see if the Optoma's were in stock. can't wait for the panny to arrive. I'll post on the results....Also was wondering if anyone had tried the Tru3D kit to run other sources like cable or Xbox360

Are the Optoma glasses better than the Xpand X102 glasses?

These NX-3DG glasses were mentioned on the JVC RS40 thread:

http://www.firefold.com/Search.aspx?k=nx-3dg

I sent an email to the vendor asking about these working on the Samsung with checkerboard 3D. Here was their response:

John,
After doing some research it looks like the NX-3DG 3D glasses should work for you. The model you have states that Active 3D shutter glasses are needed which is what these are. I have not been able to find anything that says they will not work. If you get them and they do not work please feel free to contact us. We have a 30 day return policy. Please let us know if there is anything else that we can assist you with.

Any thoughts on this? Is this all I need? These glasses and a Panasonic 3D player?

That link says this: "Note: TV must be a 3D-TV. Not compatible with older Samsung Plasma and DLP televisions which do not have a built in 3D emitter." Does our Samsung have a built-in emitter?

No, but there are glasses availble that are made specifically for DLP TV's that don't need an emitter.
