I've have a toshiba tw56x81 for about a year and a half now, maybe slightly longer. I've just noticed that there are discolorations where the 4:3 letterboxing appears. I was watching playoff hockey in full mode and I noticed the discolored columns on the sides. WHAT? How did this happen?!?!

I've calibrated the tv with avia and taken special care to make the contrast and brightness as low as possible. (Just to note, the contrast and brightness calibrations are about the most difficult I've done. Every test is different and each one has its problems.) I've set the contrast and brightness so low that players on Directv's hockey broadcasts always appear to almost be shadows.

I know the convergence is different for each input format, I think there are different display settings for each format.

I watch a varity of formats, 4:3 in 4:3 and stretched to 16:9. Widescreen movies are watched a lot.

I'm confused as to how this could happen and if there is anything I can do to correct this problem? I did buy the extended service plan on the TV and maybe it's time to call that in and get this fixed. Is that what I sould do?

Greetings

Since we don't know where you set your contrast, it may still be too high.

Burn in is cumulative like mercury poison. It adds up over time and then you have it ...

This stuff is not usually covered by warranty as it considered to be user abuse. You may be able to get it done under warranty, but it will take a lot of screaming and shouting on your part.

What color "discoloration" do you have? If you put up a white field from the VE or AVIA disc you should be able to determine the extent of damage.

It may be just one tube that's burned.

Tanks guys, I'll try the white field. What I noticed is the color was slightly darker.

I can give the settings I've got the display set at, if you want them...

All the menu configuration values are set at 50 the adjustments were done internal. The values from my records are as follows. The reason I did the internal tweeking is because of the "Reset" button problem. The biggest problem there is constrast getting set to 100 when reset is hit.

Hmmm....If the areas where the 4x3 bars were are darker, it would appear that those were the areas that experienced wear (phosphors dim with age).

What color were your bars?

The bars are the standard toshiba grey, I think those are set at... hold on let me look above in that nasty table... I can't find it, but it's a medium grey value.
