I saw a Panasonic today at Sears that had severe burn in lines at the 4:3 cut-off......it scared the hell out of me even though I would barely ever use a 16:9 tv in that mode. I know the stores set the brightness and contrast high, but still. It RUINS the set. The salesman said they left it running in 4:3 for a long time and this was the result. I'd hate to see that happen to anyone....so be CAREFUL!!!!! :-)

I used to be scared of burn in, but not anymore. A friend of mine keeps his Hitachi on all day with contrast and brightness maxed. He has never had a problem. I haven't told him to turn them down because he is kind of a jerk. Also, I am curious to see how long it takes for his set to have some kind of burn in. As long as you calibrate with Avia, you won't have a problem. Unless you watch CNBC all day, every day.
The side bars aren't even the biggest culprit. Its those pesky station logos (bugs). Especially the really bright ones. Hate is too soft a word.

This was the first time I ever saw it on a rear projection tv....quite frankly, I never suspected it to be a problem with RPTV....but it REALLY was bad...and I dont think the set could be that old. I bet your...ummm...friend? jerk? :-) will have a problem if he keeps this up. I have heard rumors that some tv's will gradually move the image back and forth gradually to prevent the burn in, but I have never seen this feature advertised, so it may be untrue. Just food for thought....

When i got my mitsubishi the contrast was turned all the way up (almost 100%), it's recommended to turn it down to about 33 percent and not leave it in one format for too long. Im pretty sure it is true that some TV's gradually move the picture around, i've read that somewhere.

I know that on the Mits, every time you put it in the 4:3 mode, the grey bars randomly change size. This moves the picture around a little.
I am sure the set was very new. I heard brand new sets are especially succeptable to burn in during their break in period. The CRTs wear quickly until they reach their "groove"
Still, I used to be REALLY paranoid about burn it. Now, I never give it a thought.
I do see burn in all the time. Where I work we have a bunch of huge plasma monitors watching CNBC all day. When they go to a commercial, you can still see the ticker burned in the bottom of the screen. What a waste.

I find that watching TV channels in expanded mode will usually cut off most tv station logos.

I wonder how well this prevents burn-in

Dont worry....someone will sue the TV stations over this sometime soon and they will all stop putting the dumb logos on the bottom one they pay out $40 billion for tvs. :-)

No, I fear the networks are going to go the other way. They are going to make the logos more like the European ones. Instead of just logos, we will have advertisements and even commercials. It will look like Bloomberg TV. The spanish stations in Houston have started doing it during soccer matches.
That is not even the worst part. You know that technology used to put the glowing yellow first down line in football can also be used to put anything else on the screen. So when someone on a tv show drinks a coke here in houston, it may be a pepsi over in NY depending on who pays the most.

If they would rotate the darn logos after every commercial break, I would be very happy.....

That is one danger of buying a RP that was a floor model. If you vary your veiwing the logos will not be a problem It is best though to stretch all your pictures if possible.

Is it just me or do the logos not seem to be as bright as they used to?

I think a lot of networks are using translucent logos. They are still annoying, but getting better. Sometimes, however, the local affiliate adds their own logo on top of the translucent one. News programs are the worst offenders.

The guy with his contrat and brightness maxed out must not be worried about the life of his guns.
I have heard they cost upwards of 800.00 to replace.

Replacement CRTs (the only fix for burn-in once it happens), I think are around $250-300 each. There are three of them, and in more extreme burn in cases all three may have to be replaced.

If you get one that uses the DLP system from TI, there is no chance of burn in.

Just get a Pioneer series (ie. SD-532-HD5) and use Natural Wide mode... works amazing! People are always comenting how good the 4:3 image looks in 16:9 with Natural Wide.
No burn in probs here!
