SOURCE: screen flickers

This an be the power supply, or there is a component on one of the processor boards that is starting to fail.

The only way the tech can service this is to have the set opened, and wait for the fault to occure. When the set is doing the fault, he has to check the power supply distribution outputs, and at the same time use a digital scope to follow the video path through the various stages. This is a long an complicated process to find the exact fault.

Once the tech knows which board is giving the fault, he can then change the complete circuit board to fix the set.

I think what is happening is that when the set is coming in, they are not spending the adequate amount of time on it to find the fault. This type of problem is very time consuming to find.

What you can do is make a video of the fault, write the video to a DVD, and bring the set back with the DVD to show them the fault.

If you have a friend with an HDTV you can bring your DVD player to his place and try it for a while on his TV set. This would verify the player for sure.

I doubt you have an AC power problem. You can easily prove the AC power by putting a lamp on it.

When I have had this type of fault, I ended up finding the defective board in the TV and replacing it. One time, it was the customer's DVD player that was causing a fault.

Next time you buy a TV set I would suggest to you to pay a little more and stick with a major brand of TV set. They have better factory support, and are of better quality.

SOURCE: samsung 40 inch lcd mode not supported

My 360 and samsung hdtv worked fine for about a year and now im getting the problems mentioned above, not sure if its a console/cable/telly problem but i did the following (temporary?) fix

Unplug your 360 and plug it into another television set, it seems to reset/calibrate itself somehow and then when you plug it back into your samsung tv it will work - mine did but for how long i dont know.

SOURCE: when i turn on my samsung lnt5271 the screen seems

This sounds like a repair issue. I do not believe there is any in-home troubleshooting that you can try that will fix that particular issue. I would call Samsung tech support to see what their opinion of the problem is. Their number is 800-726-7864.

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please post a comment if you need additional assistance so that I can help you further.

SOURCE: my 32 inch samsung lcd tv has got faint black

Are these lines on both side of the screen or what location are they in? They can be caused by watching 4:3 television with the black bars on both sides. Watching 16:9 full screen HD wont cause issues with that. If only on the sides there is not much you can do except put a pure white screen on the TV and leave that on for at least 6 hours. This will age the panel a little but in theroy wil even the pixel burn you have to make the lines less noticable. Please take a few moments to rate my answer. Thank you
