Sounds like someone stuck a magnet to the screen.

It sound like it took a power surge. suggest you either have it serviced or replaced the tv itself. Frankly if it is not under warrenty then it is time to purchase a brand new tv.

Difficult to address the black screen problem without diagnosis but the blue discoloration is definitely a bad optical engine. Sony extended warranty coverage for this until June of 2010 but no more. Cost of the part is around $900 so I wouldn't pursue any further repair.

I am starting to get a discoloration in the bottom left side of my screen. It is slowly making it's way up to the middle of the screen.


If it is a tube type TV, probably needs degaussing. The screen within the crt becomes magnetized or external magnets from speakers are causing a problem. Sometimes changing the direction or position the tv faces causes degauss problems. If moving nearby speakers changes the discoloration, then speakers are too close or TV needs degaussing. Some high-end Asian tvs have E-W adjustment in users menu to correct this problem.

If it is RPTV 3 tube crt TV, maybe a convergence problem.

If it is DLP or LCD rear projection, probably optical engine failure.

What model is TV. Is picture normal in BW with color turned off?

When your watching non HD channels you have to stretch your screen.Your TV has that input option to do so.

50 INCH HITACHI ULTRAVISION HAS COLOR DIFFERENCE ON EDGE OF SCREEN


Hey, I found this on a blogsite about lcd rear projections....looks like our tv's screens have been burned by the "pillers" that surround the tv when switching from 4:3 to 16:9 or fullscreen... read below, I hope it helps !
cheers!

Rear projection crt's,the first generation widescreen tv's were notorious for that.Lcd and plasma can have the same problem,but it takes much longer and is not as harsh.Dlp's use tiny mirrors,so it isn't a problem with them.Lcd and plasma tv's should be ok unless you watch them with blck bars on them all the time.
We have lcd monitors at work,and i've seen them after a year with bad burn in.They also run 24 hrs a day 7 days a week with the same display.



GKar posted 2006 Oct 10 15:31 TooLFooL : i have 51" sony rear-projection and those freakin' grey bars burned themselves right into the screen...

I read that to avoid the burning you had to limit your 4:3 viewing time to 15% of total time viewed. (applied to my TV but apparently yours and others as well...great! now they tell you :-x , this applies unless 4:3 aspect was changed to stretched or zoomed...yuck :-x )

This really sucks as a Star Trek/Lexx/Farscape fan as they are mostly 4:3, fortunately the upconvert player/hdmi combo sends a 1080i 16:9 signal to my TV so the effects are drastically reduced by nearly filling the TV without the grey bars or burn in problem without stretch or zoom modes being used. yay! :wink: (default grey bars set to black automatically, apparently grey isn't needed due to screen area covered is sufficient for burn in not to be a problem.)

Viewing HDTV on a Sony 53" KP-53HS30


This TV is a projector - not a plasma. I can't see how you would get "burn in" on this set. It should handle an HD picture fine.
