Question about Sony KP-57HW40 57" Rear Projection Television
This might be a convergence issue. I can tell you that the site that Jean posted will not fix this
problem and could even make things worse. That sight pertains to a specific problem that is common in
some Sony sets and should not be used to try to fix any other issue.
Please keep in mind many things can go wrong with TV sets and you should really do a lot of research before attempting any adjustment and or repair. There are high voltages present and they can reside even when the set is unplugged.

The problem with the colors not aligning is due to a convergence IC failure this has to be repaired by a competent tv repair shop, expect to pay 300 to 450 dollars. Julio at Millenium TV (702) 736-1091

Ken , the poster of that Blog writes........

color ray gun tubes that get out of adjustment.
They are also known as retrace lines."............

Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.
Here are some of the most common symptoms and example photos of a convergence problem
Here is a quick test....
Using your original remote go-to the tv settings then goto the convergence section.
Try to adjust the red and then the blue convergence.
You should be able to move them up, down, left, and right.
If you can't move them in all directionsthe screen has blue green green, red outlines how - 2c07611.pngrgence chips are bad and should be replaced. This is a common problem.
You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.

The Samsung has bad convergence IC's most likly. This should be repair ONLY by a trained technician as a TV set is not a place to experiment or tinker with because of the extremly high voltage inside. This repair should cost you in the range of 250 to 400 bucks . Good Luck

YOu have convergence issues. Ok first question. IN your setup menu do you have the convergence option/ if you DO not then it can be a specail fusable link. fl231 if you do. next question do the picture bow in at the middle. if you do then it possibly a convergence power supply issue. next if you go into setup convergence does the crosshairs adjust up or down left to right on both blue and red. I if so then theres is a chance that it can be a convergence adjusment or a amplifer problem AS always THIS SET CAN GENERATE LEATHAL 380 VOLTS EVEN WITH SET UPLUGED SO BE CAREFULL.

This is a convergence problem. You will need the stk's changed and a pico fuse or 2. also from looking at the pic you might want to clean the lenses and mirror after the repair to bring back some of the vibrant colors the set once had when it was new. This repair should run you anywhere from $300-$500 depending on your area and the tech that comes out. If you need more information or would like to try to fix it on your own please let me know.

TO REPAIR... 1. Warning. this set can
generate leathal dangerous voltages even unplug do not attempt if you
have no experence with electronics.
2. Remove the back. there a number of torx 20 screws.
3. what you will see is a number of circit boards There will be one on the right and one on the left. the one on the right is the small signal board. the one on the left is called the power deflection board. it has a large black part with a big red or black wire coming from the top, this is the flyback.Next to the flyback on the right of it there will be three small rectangular componets tan or brown in color. these are fuses. the one in the middle is the fl231 fuse it should be labeled that right on the board.
4. getting to this fuse can be difficult. these two cuicit boards sit on a tray that is removable. to remove this tray it is pulled out and up. BUt watch the wires.loosen the wire tyes.
5 when you get the tray up the bottom side of the board can be accessed
you will now have to unsolder that fuse. one side of this fuse is under a plastic part of the tray. i have found the easest way is to cut away the plastic to get to it. if you dont want to do this you will have to remove the board. only remove half of the plastic brace
6. REPLACE FUSE RCA PART 259213 or you can goto radio shack and get a inline fuse holder and get the smallest glass fuse they have witch is .75amp witch is 500ma and all together cost about $5.00
7 RESOLDER FLYBACK CONNECTIONS or both ends of the inline holder simply heat up and add a little solder
8 reassemble set. make sure you examine the set for loose connections.
9 and remember "BE Careful'

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 a convergenece repair kit with instructions from the links below.
Here are some of the most common problems with these sets...
Problem #1) Convergence
Yours may have one or more of the following symptoms...
*Screen Looks 3-D
