SAMSUNG 61”, 56", 50” & 46", HD 3 Panel LCD RPTVs.

Recommended Posts

Hey guys thanks for that. I've now pretty much decided on the  SP42L6HX (for a damn good price of less than $2500), EXCEPT I walked past the Good Guys today to see the LG  Model : 52SZ8R (which is the 52" DLP model) for $2750, including delivery AND a 3yr warranty!

What should I do??? arhhgg!

I'm interested in that Samsung model as that's the best size for me. The LG DLP screens seem rather dark however. Samsung claims 1000cd/m2, while the LG you mentioned is only 400cd/m2!

I've also read up on a few threads in this forum about some problems with LG ownership.

Can you tell me where you got the Samsung for under $2.5k?

Well, my Sammy 56" is now 14 months old and has now aquired a yellow tinge in the shape of a  quarter moon.  Fortunately took out a 5 year extended warranty, so will be calling the Servicing agent tomorrow.

Anyone else come across this problem before?  How can it be fixed?

I've noticed the same problem on my 46" Sammy LCD - I have a brown / yellow tinge that is oval in shape and fills centre 70% of the screen. It's not noticable all the time, only when the background is a light color and fills most of the screen.

It's about 12 months old, and I watch it on average of 3 - 4 hrs a day.

This is my 2nd LCD unit - the first lasted 2 months before I had it replaced with dust blobs. I'm going to get a service technician to look at it and see what can be done.

Martonl - Your problem sounds like mine. It started as an oval area in the center and gradually got larger. Please report back on what you find out. At this point, Samsung has said it must be because it is too humid and I can't argue because the service agent "fixed" the problem by letting it sit in his air-conditioned shop for several days. However, we've tried everything we can think of to make it a less humid environment and nothing seems to help.

HARI - Thanks for posting that picture. It doesn't really look like my problem, but I still think it may be dust. When we first took it in, we assumed it was dust on a lens or mirror somewhere in the system but when it cleared up it seemed to eliminate that. I don't suppose the lens is anywhere accessible where I could look at it?

These problem - yellowing centres are caused by the polar filters aging and failing.

IT IS NOT DUST. IT is NOT humidity. The organic compounds break down due to HEAT stress and develop microscopic hair line cracking causing a colour spectrum shift from white to yellow and blue uneven spectrum light spread. The LCD panels can also a break down due to heat stress as well.

Tip: NEVER NEVER TURN off these sets at the power switch - front of TV or at wall power socket. There is a gradual process of startup for fan cooling and shutdown. Simply the fan for cooling instigates (FIRST) on startup and cools after a 'soft' power down for around 2 to 5 minutes. Ensuring this this will PROLONG the life span of everything.

They replace the entire light/polar unit/lamp as ONE unit. These LCD light engines are made by Epson. They are also the same type found in LG's.

Had mine replaced @ 11 months old! Took SIX WEEKS to fixed though.

DA

Well, the microscopic hair-line cracking might account for the wiggly clear sections and the gradual spreading from the middle sounds right. But I can't account for the fact that the problem disappeared after several days of sitting in the service agent's air-conditioned shop, then gradually re-appeared over the next few months. Also, I ALWAYS use the remote to turn it off. My problem is with a reddish haze, not blue or yellow, but perhaps the red LCD light engine could be cracking. My TV was 6 months old when it started. I would love to have an explanation. Do you have any more thoughts?

GLO: So you have already used up a globe? Why the change to the lower wattage?

Impakt

My bulb exploded, dont know why, but it was covered by my extended warranty.

The ballast was changed at the same time.

Just a note on this...

Harvey Norman City West in Perth has 3 (Sony, Sammy, and Toshy) 60" RPTV side by side, fed by Sony HD STB....through component, I have to say I wasn't impressed by the Samsung, the Sony and Toshiba are in par (Toshiba's black is better, though Sony's contrast is better)

Bugga!

I had to format my laptop due hard drive failure.

I had the VGA output set up brilliantly before. I have a 46" unit. No grey borders. After I formatted, I tried Hari's driver and then powerstrip, but no joy. The grey borders are back with avengance.

I cant for the life of me remember what tweaks I did to eliminate the Grey border with VGA out, it just worked. Now its back and p**ing me off.

Anyone got any clues on how to remove the grey borders?

What display adapter does your notebook have? I'd say you might need to update your gfx card drivers, before you can really remove the borders.

I use the latest CAt 5.7 and install them to my insipron using a little software hack.

The thing is last time i used your drivers it was Puuurfect man!. No grey border at all. Now after the format, no matter what I do it gives me the black borders. Its one of those times when you get something right and cannot work out how to do it again. Because i had no border before , its much worse going back!

It might be that I used new drivers but as I recall before I formatted I have used cat 5.10 through cat 5.6 and the border was gone so im not too sure its driver related.

Can you tell me hari what drivers you have and what settings. Im using your driver. Thnaks for the great work btw :blink:

I'd say it's driver related, because I have found with ATI that for some reason some versions of the Cat drivers just fail to switch to the resolution you want on HDTVs. What you need to do is fully un-install the Cat 5.10 and install 5.6. After you have installed the Cat 5.6 drivers follow this guide I had made and posted a while a go in this very thread.

Copy and paste the code below paste it into Notepad then go to File save as change the save as type to All Files, Lastly name the Driver Samsung.inf make sure you do not save it as a .txt as it will not work.

MAXRES="1280,720"
MODE="MODES\1280,720"
RANGE="30.0-70.0,50.0-75.0,+,+"

Now to install the driver:

1. Go to My Computer right mouse click then select Properties.

2. Now you should be in the System properties window select the Hardware Tab then click on the Device Manager Button.

3. Once in Device Manager select the Monitors and right click on the Default Monitor and select Update Driver.

4. The Hardware update Wizard will start.

5. Select Install from a List or specific location then press the Next Button.

6. Now select Don't Search. I will choose the driver to install.

7. Now you need to click on the Have Disk button and a window should come up asking where to copy the files from.

8. Select browse choose the Samsung.inf file and press OK.

9. Samsung 61 LCD RPTV should show up select it and press Next.

10. You might get a window saying that the Driver has not passed windows logo testing just press Continue Anyway Button.

11. The Driver should be installed now.

Hi,

Had Sound & Vision Technician come around this morning to look at my 46" Samsung. They are going to replace the LCD light-engine. The tech said that the issue is due to heat degrading the LCD panel. If your monitor is still under warranty I would get it checked out - give Samsung a ring & they can give you the details on the nearest repair centre.

This is my 2nd unit in 14 months - the first lasted only a couple of months - it got dust blobs & bad keystoning - they replaced the entire unit ... At this rate I'll be on my 3rd unit by July 2006 - at which time I'll prob sell it!

How long did it take to order/replace the engine?

Thanks for the information. I'm on holiday now, but I'm going to contact my Samsung repair center as soon as I get back and have them take another look at it. What a pain!

I have started to have problems with syncing of sound with my 61 sammy & the crappy hd937. Has anyone else experianced this? Its been fine for the first 14 months & has only just started happening. Gets very distracting at times.

Just wondering if anyone has tried the oppo dvd with this display & if it is a significant improvement over the hd937

thanks

I still havent solved the grey border issue and now I have tried 3 differnet laptops. How annoying. Its looked great when I had it removed before. :blink:

Also, my samsung turns itself off after an hour or so. I have an extended warranty so i will get it looked at. :P

It self powers down due to some self diagnostic failsafe as far as I can tell. Oh well. Otherwise I love my TV!

What video card/s are you using, and which drivers??? (sorry, i just read your previous posts.. Make sure you do an ATI driver clean, cause old driver stick around in the registry! Even the default windows ATI drivers)

In my HTPC i have no grey borders using the force DVI feature of the ATI drivers. The latest drivers also let you customise the actual screen resolution to eliminate overscan.

Re self shut down, just check the LED status under the screen and reference it to the manual. In most cases it would be an indicator of lamp overheating, so just ensure that your lamp ventilation is not restricted. Keep in mind that a faulty balast could be causing this problem also.

I have finally decided t call in my extended warranty. Mine is shutting down 5 -6 times a day. The error message is

LAMP - Flashing

STANDY/TEMP - FLashing

Manual says it is " Air vent cover not properly installed" in the manual for this. Of course ive never touched the unit so i dont know whats happening. Sounds like overheating to me.

But can you please explain your comment " FAULTY BALAST" what is this problem?

Still got the grey bars.! cheers
