Question about Sony KP-51WS500 51" Rear Projection Television

Kp57wv600 Hi, Had green arched lines and searched for a repair and found if I tweak the top green adjustment I might be able to get rid of the lines. Well now it is really green and shuts down after 5 seconds or so. Any thoughts? Thanks, Dave

Re: kp57wv600

Replaced may be very drastic. What you should take a look at are the settings for the convergence / retrace lines Basically you need to open the TV and the job is about 15 minutes to solve the issue with arched lines, either blue, greed, or red. There is a great how-to guide here:

Re: kp57wv600

One of the convergence output IC's has stopped working and needs to be replaced. If the IC shorts out then it will draw too much current and possibly blow a fuse, and the set will shut down to protect itself. The IC should be replaced and the set realigned by someone with experience in convergence circuits.

I have a sony big screen kp57wv600 and the picture looks like I need 3D glasses. The pictures has a green and red hallo all around the outer picture. The picture is clear in the center and goes out and is...

Sir the problem of your tv is the convergence to narrow the problem try to adjust first the convergence settings using your original remote go to setting menu then to the convergence setting, you can adjust the red and blue convergence, you should be able to adjust the red and blue left, right and up, down you should align the red and blue to green but if you cannot move them far enough or if you cant move them in any direction the convergence IC is already defective replacing this IC will fix the problem, you will find this convergence IC attach to a large aluminum plate this aluminum plate is the heat sink. It is easy to locate if you remove the back cover of your unit be sure to unplug your TV
this is the convergence IC if you remove this try to observe also if there is a cold solder or dry joint because sometimes this cause your convergence to malfunction observe the solder part of the convergence.
This is a cold solder or dry joints you can fix this by resoldering using a soldering iron, soldering lead, and desoldering pump but be sure not to connect separated pins it may cause much damage to unit if accidentally solder together. To replace the IC convergence try to check this link hope this helps good day and best regards.

I have green arched =lines r=going through my screen How do I fix this?

If the lines are slanted up from left to right and spaced several inches apart, you are seeing the vertical retrace line. In that case, you may want to turn down the screen voltage on the green CRT. The instructions for making this adjustment are given in the service manual.

It should take just a small tweak to hide the retrace line. If adjusting the screen voltage won't do the job, check for a leaky or improperly biased CRT driver transistor, then compare the video waveforms with one of the other CRTs to make sure the voltage at the vertical blanking interval is correct.

In the worst case, there is a problem with the CRT. This is generally accompanied by occasional arcing (bright green flash or the set shuts down with an error code flashing on the power light).

Arched pink lines across screen. Now green and pink double stacked wording.

Projection sets have two very common problems.

The first common problem is convergence

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Removing green crt

More than likely you don't have to replace the CRT. Go to this blog for instructions for how to fix the most common problems.

At the bottom of the page there are comments from users. There are several users that explain how to take off the front panel and where things are located. The model KP57WV600 is different than the pictures in the blog, including the fact that the order of the red, green, and blue adjusters are different.

If you try it and it's not successful and you still want to try to replace the CRT yourself, google KP57WV600 service manual and you can buy it for $9.99 and download it right away.

I wish you well.

Red arching lines

is this that you are adjusting called convergence? If so then if it's really bad you can try to reset convergence, if not then the red needs to be aligned up with green first then blue on green. Can you provide a picture of what it looks like?

Screen Turns Blue and shuts off

Go to this site, follow the instructions, and it may fix your problems. I did, and my tv is better than ever!
I was having this problem with blue. I was able to fix it, and now my tv works again. 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.

I got this TV for FREE from a guy posting it on craigslist because he saw "BLUE SWIRL LINES" also knows as "Retrace Line" on the screen and he went to several repair people and got high repair costs so he was giving it away for free, but i found a guide that tells you how to adjust the tv to make the blue or green or red lines go away, aparantly the line show up because the voltage on the color ray gun tubes that get out of adjustment. Here is the Link to the REPAIR GUIDE.

Green arcs from bottom up with darkest one at bottom on dark screens

there is a way to get rid of the lines, you need to enter a code from your remote to access a hidden menu. From there you can adjust the lasers in the tv(green lines)I beleive it is very sensitive though, if done wrong can reck the tv. Not sure of the code or directions on how to exactly adjust the lasers, actually looking for them my self. Hope i was some help though!

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.
