SONY KP57WV600-Turns Blue

I have a Sony KP57WV600 that I bought 4 years ago. It started just showing blue arched lines when the picture was dark. Now when you turn the TV on the picture is fine for about 2 seconds, then the whole picture turns blue and gradually the picture starts coming back in. When I contacted Soundtrack for their advice, they told me it does not sound like a bad tube b/c the picture would not come back in. What do you think? Would the repairs and labor cost be worth the repair? I paid approx. $2700 for the TV.

    I have the same TV and am experiencing the same issue. I really don't want to replace this TV yet because the picture quality of this TV is just as good as the TVs being sold today (other than the blue lines)

    I am having the same problem with a 65" rear projection TV. Largest and most expensive piece of @%#% I ever bought. Do yourself a favor and stay away from Sony products. Buy a Hitachi :)

    Can I purchase a focus block and put it in myself? If so, where can I buy it from?

    Hi all, I unfortunately have the same issue. Bought the tv in 2001. Now I notice that there are arched blue lines throughout the picture. They're more visible when the programming is darker, but they're there all the time. Think it's the TV or some kind of external interference? Checked the manual, but it doesn't seem to address this issue. Anyone know how to fix this??

    At least I think I have the same problem. Picture is, for the most part, great, but, in dark scenes, there are "parallel" arced lines (because arced lines can't be parallel, but that's the best way to describe them) that are two or three inches apart. When I switch from the cable box input to the DVD, say, the screen goes "black" (dark green, really), the lines appear as bright, green lines. When I hook up my camcorder, put it in VCR mode, and pause the picture, the picture tube turns blue (as it's supposed to), but those arced lines are then light blue.

    As others have said, it's most evident when the picture is dark or closer to a single shade of a single color. During bright and dynamic scenes, it's not really visible, but if you're watching a movie, and really getting into it, the sudden appearance of those lines can really break the movie's spell.

    I have a B&W LCR600 center channel speaker mounted on a shelf that rests on top of the TV. I thought it might be a problem with that, but the speaker is shielded, and when I took it off the top of the set, the lines remained behind. My B&W 603s3s (my left and right speakers) are not shielded, but they're at least three feet away from the tv, and so not apt to induce any funky magnetic issues.

    I've maintained the extended warranty on this set (it's come in handy as I've had to replace the red and blue CRTs and have had a digital board inside go bad), so I have a service rep coming out on Friday to check it out.

    I'm hoping it's a piece of failed hardware that they can't replace so they'll have to give me a new, more modern set, but I'm not holding my breath.

    I have the same problem with the arched blue lines on my KP-57HW40, that really stand out on a dark screen, also after a period of time the screen will begin to take on a blue hue and rapidly increase until the set turns off on its own. This will persist several times after you manually turn the set back on. Very annoying, and quite disappointing since the set cost me $2400.00, could this be a bad blue projection lamp? What is your take on this.

  • guestca Apr 29, 2009

    I have the same problem. The picture is fine when you first turn it on then it will go to all blue and then disappear. The sound is fine though. The stand-by light continues to flash too.

    Did any of you resolve this problems and if so, how?

    Is it the bulb? Or what is it? We recently hooked up a VCR to it too - have any of you had that problem with it?

    BTW - we bought this in February 2003 and it has worked perfectly for the past 6 years!

    Thanks for any help!

I had the same problem with the arched lines on my KP-57HW40 for a while. Then, slowly the screen turned blueish/pinkish and one day the set just shuts itself off. Sometimes, it's fine then gradually turned bad. I got it in '02 for $2,700. Some Sony licensed repair shop said it'd cost about $600 to replace the bulb if it's found to be necessary. I was just so tired of this chunky junk that I gave up and bought a Samsung LCD. Now, it's sitting in a room waiting for a willing taker.

Yes ,it sounds like screen adjustment or focus block, should be around $200- $325 to repair.

Picture is very blue, especially in dark scenes.

Sony TVs has an Optical Block issue. If there is an issue with the optical block, then there will be green, blue patches or tint on the TV display. Try resetting the TV to the factory settings and try Power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue still persists, then TV may require service. You can contact the Customer relations team and check for the available options. Sony had repaired free of cost for such issues. Hence, contact the customer relations.

Sony KP-57WV600 rear projection

sounds like bad CRT, some of these sonys have had defective CRT issues, usually all will come and go sooner or later (all 3 bad), you can pull the speaker grill off(either 2 1/4" screws on bottom or 6 1/4" on back sides) and pull off the Crt box cover (2'X3' piece) and lightly tap the CRT's with tv on, if they flare or get colored streaks in pix they are bad, CALL SONY 800 # and complain, also could adjust G2 (Screen control for color) for short patch. Will need new crts.

Faint red lines in a curved arch like pattern

Guys I did this myself real easy. Just don't turn the corresponding screw too far. Only need to adjust it until the lines go away. Do it on a darker screen so the lines are more visible. I did the red 2 years ago and the green 6months before that. The blue lines are coming on my screen now and I've fixed it in 10 minutes. The TV is amazing.
