I have a 42" rear projection, hi-def, akai tv. About a year ago I noticed faint "shadows" of lines on both sides of the screen, exactly where the low def picture borders begin. The shadows are not visible on low- def, only hi-def. I've gone from DISH network to DTV and they remain, so its not the signal. Is it time to call a tv repairman? The tv is about 3 years old.

You have SUBTLE 4:3 Format burn.....
IF you LEAVE it in 16:9 Full screen mode for a couple years, you might see it even out....
OR HOPEFULLY...you might try this....
Set your TV to 4:3 mode...then go to a BLANK video input....
Hopefully, when you do this, you end up with GRAY pillar bars and a BLACK Box in the Center of the TV.
<
But you want to do it one hour at a time....
Leave it in that mode for about 30 minutes, then check it every 30 minutes with a FULL SCREEN 16:9 picture....
But it may take up to 40 hours to darken it...or MORE!!
That's the FUN thing about rebalancing the phosphor, trying to get it perfectly balanced.
It takes time and a keen eye to do it....
I only suggest the ONE HOUR increments because you don't want to OVER DARKEN IT.
And I suggest you minimize your 4:3 viewing to no more than 15% of your viewing time.....It should only be viewed FULL SCREEN for the MAJORITY of the time.

Yes, that's burned. It's the most common reason why more people are going away from projection and to the larger LCD screens that are becoming more standardized. See if you can call the repairman and get a quote. It might run almost half the cost of buying a new flat-screen. If that's the case, you might as well upgrade and get the better picture quality that comes with it.

The images are probably burned into the phoshors of the crt's . Replacement is very expensive, likely $1000 give or take. Call a tv tech. to find out for sure.

Not only is it possible but it is very common with rear projections.
