Faint blue arched line across picture

I had the same problem with my sony KP-57ws500 rear projection tv. To solve this problem all you need is a flat and phillips screwdriver. Right below your speakers on the right and left side are tabs. Pull out the tabs and remove the screw on eachside. Once that is done remove the speaker cover and you will see a fiber board cover in the middle of the tv, there will most likley be twist ties holding some wires, to make it easier to work remove the ties. Now remove the screws on the fiber board and pull it off. You should see 3 adjustments on the top for focus, do not touch those. Below the focus adjustments on the bottom is the blue, red, and green adjustments (they should be labled). All you have to do is turn adjustment screw slightly to the left(or counter clockwise) and it should clear right up. I'm not a technician but i read up on it in a repair manual and it worked perfectly and saved me a $100.00 for a service call. It took about 10 minutes to do. I also have a friend who expiernced the same problem with a different model sony projection tv and it worked for his also. Apparently this is a common adjustment that needs to be made espicially if the tv is moved.

I was having this problem with blue. I was able to fix it, and now my tv works again. I think I have to adjust the colors a little more, though. Thanks for posting this!! For those having trouble removing a different front panel, here is what I found on mine -

I own a KP57WV600. Removing the front panel is a little trickier on this model. You remove the 6-8 screws on each side behind the two speakers. You will access these from the lower rear/sides of the TV. Remove the small 2ft plastic pieces. Now from the front of the machine grab the entire lower piece (speaker covers & power/volume/chanel buttons) from the bottom and pull down and towards yourself. There are 4 slots that this piece fits into. I had to take off the lower back panel to see why it wouldn't come out. Don't pull to far because this lower front piece is connected to wires. I'd say you have about a foot of play. Now you can remove the fiber board panel and access the blue/green/red lower screws. When you adjust these, go a fraction of a milimeter at a time.

HI I'm a 14 year old kid from Florida. You have no idea how much this helped me. We recently got a kp-65wv600 from a person giving it away because it didn't work and it turned out to have the "Wavy Blue Lines of Death." I did exactly what you said and the tv looks amazing. Thanks for everything you just save me $3228 + the $100 from the annoying repair people who don't tell you a thing. You have no idea how happy I am

Hi i just had this problem. i have a sony kp-65wv700 and the screen was blue for about 15 to 45 sec so did some peeking around found out that if u just take off the front cover u can find the volts and focus controles up front all u have to do is very lighty turn the blue volts nob witch is the left one on the bottom.or what ever it its turn it counter clock wiz little bit less then 1/8 in good luck!!!!!!

Please help me,
i remove all the screws to hold the front and lower front panel, and cannot get the lower front panel removed (afraid to break). Can anyone tell me how to remove the front lower panel (speaker area) for the KP-57WV600. Thank you.

THANK YOU!! My version of this was red and green arched lines, most noticeable in Zoom mode. Just took a tiny counterclockwise tweak of the screws. Why wouldn't Sony online chat tell me this? maddogmic - you are great!

Hello,
I just want to say thanks. This tip fixed me right up.
I got a 65in. KP-65WV600 from Craigs list today for free, and it had a major blue shade over everything and also some lines arching around the screen. Just a little turn to the left of the blue knob....BAMN!!! the color is great and the lines are gone and I have a great looking free TV.

D.

Thank you so much fix ya!!!   YES the solution that was offered was EXTREMELY helpful.  Me and my husband found this TV in a pile of trash in front of the neighbor's house and decided to try and fix it.  The fix took 5 min at 1a.m. at home with 2 screw drivers.

Solution:  Far left screw is Blue turn counter clock wise
               Far right screw is Red turn counter clock wise
               Middle is green turn counter clock wise
only turn very slightly
don't touch very top focus screws
helps to have a handy husband!

Man thank you so much for the help. I have been dealing with those damn red/green waves for like 4-6 months! This is very helpful and I wish I could leave you some kind of knowledge also. But I think you know what your doing alright! lol. Again, thanks my man, you really came through on this one!

I had these blue lines pop up about 3 years after I got my TV. A tech came out once, and adjusted it, but they came back about 6 months later. The second time they came out they replaced the picture tubes (service plans are good).

About 3 years later, the blue lines came back again. I fixed it myself this time, but who knows how long it'll be before they're back again. Here's what I did for my 57" Sony widescreen rear projection:

- Pop open the front bottom of the TV. There's a few screws on the side, facing rear, then there's 2 somewhat hidden screws under a couple of caps below the speakers on the front. The bottom panel slides out a few inches from the bottom, then down towards the floor. There are wires attached to this, but I was able to push it far enough aside to keep digging.

- Pop open the smaller panel in the middle (previously hidden by the panel you removed).

- There's a bank of 6 adjustment screws. On my TV, the 3 on the bottom controlled the horizontal arcing lines, blue on the left, green in the middle, and red on the right. Turning the bottom left one counter-clockwize got rid of the lines.....for now......

The fix worked perfect my green blue and red was showing and with you tip it is perfect i was going to buy a new tv saved me thousands to 1o minutes or less

Awesome fix, it could'nt have been any easier. In my case, I turned the blue screw a 1/16 of a turn counterclockwise and it cleared right up. THANK YOU !!!

Increditable !!!!! been feed up with my sony kp-65wv600 darn green lines been driving me crazy almost sold it till i found your post can't believe it was that simple now its as good as new thanks alot.

That's awesome i just fixed my tv, thank you so much

It only took 1 day from when i had faint blue lines show up to a total blue screen.  Did the repair and now the tv looks better than it has in the last year.  Thanks to whoever submitted this fix and to everyone who contributes to boards like these.  

Thanks for the tip and it worked,The brown board is the fiber board mentioned it will still be attatched to the TV.The screws may not be marked,my blue was the left most screw.i had tv on after i had removed speaker cover and fiber board and it immediately fixed the problem

Wow! Thanks! I was just about to call a repairman and your suggestion worked! Lines are all gone. Thanks so much!

Great advice. The problem one on ours was the green adjustment. Sony has white paint on the adjustment screws. It may be helpful to mark the white with pencil to mark original settings.

I had the same problem after moving and the adjustment saved me some headache. Thanks for the advice.

Thank you to maddogmic for this great advice. We were thinking we were going to have to either pay the $400-$500 to have the tubes replaced or buy another TV, and my husband found this advice today, we followed it step by step. THANK YOU!!!

Wow! I never thought it would be that easy. My KP-65WV600 has had the arcing blue lines for close to five months now. It was driving me nuts. I had planned to call a repair shop up, but decided to take a stab on the internet first. I took your advice and now things are back to normal. Thanks.
