I have a Samsung Slimfit tv, model # TX-S3079WHX, and know that the slimfits have geometry issues. Most of the issues have been able to be adjusted properly, except for one annoying one and I have no idea what setting adjusts it. Tech was here once and said it is the best I can get, but I am not satisfied and he is returning next week to look at it again.
The problem I have is with horizontal lines when the crosshatch pattern is displayed. If you start at the top LEFT side of the screen the lines on the top half all slope down towards the center of the screen gradually the farther right you go on the line, and starting at the bottom LEFT of the screen they do just the opposite, they gradually slope up towards the center the farther right you go on the line. Sort of like this > although that is an extreme example, hope you get the idea. This is very noticable when I do not zoom or stretch an image while watching tv and there are the black bars on top and bottom of the screen. Is this acceptable for a geometry issue or not? I took a tape measure and the top and bottom left corners of the picture measure like 2 inches from screen edges, but top and bottom right corners are like 6 inches from screen edges. I find it hard to believe this is an acceptable geometry problem. TV is only a month old. I have played around in the service menu with the crosshatch displayed, but see no adjustments for this problem. What do I do?

4 inches difference? Are you kidding, or am I just misunderstanding your description? Do not pass "Go", and do not collect $200, take that POS back ASAP.

4 inches is way beyond anything that could be adjusted in the service menu, even if there was a setting for this type of distortion, which I'm not even sure there is.

4 inches???

Well it depends on the channel and the program I guess, right now a commercial is on foxhd channel, and it is an inch and a half difference, so I am confused. What is an acceptable difference?

From what I have read about the Slimfits, the horizontal geometry is not fixable. Sorry.

For me, maybe a quarter inch, but that's just me. But If the screen size is changing constantly that really sounds bad to me. Hopefully you are still under warranty, because that should really entitle you to a free replacement or repair.

In sum, from what you describe, I would say that TV's performance is totally unacceptable.

That's exactly what I think, now how do I convince the tech to replace the tv since it is only a month old and under warranty?

Tell them they sold you a TV that doesn't work properly and demand a replacement.

Why can't you just return it to the store where you bought it? And if you are slightly beyond the store's return period, try asking anyway.

If a TV is defective, a store will often bend the rules a bit to keep a customer, much more so than they will for a someone who is merely unhappy with their choice.

And if you tell them you will buy a more expensive model if they allow you to return the set, this will sweeten the deal for them.

Many people who are persistent and/or smooth talkers get stores to accept some pretty ridiculous returns of items they had several months, that got damaged, that they decided they didn't like, etc. so give it a try.

Your return seems very reasonable to me, so I think you'll have little or no trouble if you just ask, and if the person says no, ask for the manger and ask again.

And if they don't let you return the set, let us know who they are so the rest of us can avoid doing business with them

Well I think that before I go the route of returning the tv, I am going to wait to see what the tech says when he comes this coming Saturday, and if he cant fix it or refuses to exchange it under warranty, then I will try to take it back.
