Help! Samsung TXN3075WHF Gaming Issues!

This is my first post here, though before buying any television I had read through the forums for a few weeks.

Anyway's, my problem is this:

I recently bought a 30" Samsung Widescreen HDTV (TXN3075WHF) from the CompUSA that I work at - it was a floor model with image problems. I bought it because it was marked down significantly and I knew I could have it fixed under manufacturers warranty no problem.

Long story short after a month at the repair shop they were able to fix the screen and everything looks great...almost everything. I have a DVD player w/progressive scan plugged in via component that looks fantastic as well as a Nintendo GameCube and Super Nintendo game system. The only problem is that both the GameCube AND Super Nintendo have concaved, wavy black sides on the screen. Sort of like this: -->)picture(<--

I know that both game systems work fine because they display perfectly on other TV's, but I don't think that my S-Video or Composite inputs are messed up on the TV because they can display a DVD image through those inputs just fine.

Needless to say I'm very grateful for any help anyone can offer!

:D

P.S. Another description of the picture problem that may or may not be helpful (I'm really not sure) is that the black "bars" that fluctuate on the sides seem to fluctuate based on brightness and color. i.e. the picture fills in the screen more when there is a consitent bright color and decrease during black and fading scenes.

It sounds like the power supply in the TV is weak or perhaps the high voltage is set too low. Try cutting back on your contrast and brightness to see if the problem tends to diminish. You may need to back off of the contrast all the way even. If the problem is less under reduced settings, then there is something wrong with the power supply in the TV.

Sometimes there will be a problem with some other section of a TV that will cause deterioration of the power supply and even though the other section is fixed, there can still be a power supply problem. Games will show up these kind of problems more so than normal video because the video from games is more dynamic and tax the video capabilities of a TV or monitor more.

Edit: The reason why the problem showes up more on the bright scenes is it takes more power to make white than it does to make black (duh) and that is why I'd suspect the power supply.

I hadn't even thought of that as a possibility. I'll test this out when I get home.

Ideally I'd like to avoid another trip to the service center, but I'd rather get it completely fixed while under warranty and be done with it.

Thanks for the suggestion, I'll report back with my findings later.

P.S. If anyone else has this set, this is a great site with a lot of good information regarding the service menu and the risks involved with messing around in it. http://www.streamsofdata.com/hdtv/

After testing both brightness and contrast levels, the problem seems to be the same.

Oh well, back to the service center on Monday. Since I only have the problem with game systems I might take one in with me just so they have something to test it with, or would that not be necessary?

That's a good idea.

This is just my opinion. Once you get your television repaired it is never the same. I once had a '94 GE 31" television that had a repair done because the screen would show half way. I didn't know at that time since I just started high school that GE sucks under the Thomson name. Well once the TV came back it never had a straight picture. It was either tilted too much to the left or right. So in a nutshell once you have your TV repaired it is never the same.

So the service center just called me saying there is nothing wrong with the TV. Apparently they tested the gamecube on another HDTV and it did the exact same thing.

This seems rediculous that a DVD player can fill up the screen just fine but the gamecube can't?

Why is that? The DVD & Gamebox are different devices...

Well, after testing the game systems on several other 16:9 HDTV's and them all producing a perfect image, I'm now dealing directly with Samsung.

One thing I'm thankful for is their customer support seems to be excellent.

I'll post results as I get them. Any other owners of this model on the forum? PowayTV (where I took the unit) tried to tell me that it was a problem with this model. I find that hard to believe.

Update: After talking to Samsung's customer support for about 20 minutes they came to the conclusion that I'm going to have to call back on Monday to talk to their executive customer relations lady. The technician I talked to said that I will either be given a refurbished TV (not sure what model) or a pro-rated refund. Hopefully they'll decide on the refurbished TV.

Also, I tried fooling around in the service menu (after doing some research in the link I posted earlier) and was able to slightly correct the problem, but then all of my other video sources are messed up. There is just flat out a problem with the television.

Final Update: A second repair place came out to look at the TV today. Apparently the problem is that since my TV is a Flat CRT the bowing is natural. I normally can't see it because it's hidden beyond the viewable area of the screen and happens because it's a curved image that is being displayed flat.

The only time it's noticeable is while viewing something that doesn't natively fill up the screen (DVD, television, and games that are programmed for 16:9 all display fine). It's frustrating, but I guess there isn't anything I'm able to do.

It seems that about 1/3 of the games for my GameCube will actually fill up the screen and end up looking great as a result.

So long as Zelda is programmed for 16:9 compatability I will have no complaints. After that I'll be picking up a Xbox 360 which, of course, has 100% HDTV 16:9 support.

Thanks for all of the help in this issue, hopefully this thread might save someone else the time and frustration that I went through trying to get this "problem" fixed!
