Sony KP-57WV600 57" Rear Projection HDTV-Ready Television - Answered Questions & Fixed issues

Hello, it sounds like the blue crt has a cathode short in it and causes an overdrive situation putting the set into shutdown. The crt's are no longer available.

This is called Red Retrace. Your Red CRT and CRT board is defective. I do not believe you can get a replacement CRT anymore. Not even a rebuild. I think it is safe to say it is time to buy a new TV.

Power supply regulator section has the fault. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock! Instead, contact any experienced service technician, or the nearest service center. If you wish to get more details about these kinds of fault, check this link.

The Green CRT has failed and putting the set into protective shutdown. You can get the Green CRT from www.tvrepairworld.com

Google for the service manual, should be available online for free, the G2 voltage should come from the D board where the high voltage circuit is.

Hi. It seems that the g2 voltage of the picture tube is too high, resulting in a white screen, often with white horizontal lines. The g2 (= second grid) voltage is derived from the flyback high voltage. The voltage divider is mostly integrated in the flyback trafo housing.(including the adjustment knobs). A failure in this divider may lead to this defect. The static you hear may come from sparking in the divider. The flyback trafo is soldered onto the main printed cirrcuit board. Sometimes, one of the pins sits loose in the soldering pads.Turn on the set and observe for any sparking around the entire flyback circuitry, and, or the flyback trafo itselfThe screen turns black after a while, as a too high beamcurrent is detected. The set disables the flyback. Stand-by blinks meaning that there is a fault condition.Be carefull with the high voltages. The flyback voltage is very high (20-30 Kilovolts !) and may be lethal !!

how many times does it blink?

sounds like theres a problem with the tube inside the television. most of the time they arent worth fixing as its costly.

1. Remove the 5 screws from behind each speaker2. Grasp bottom center of plastic panel and "pop" forward. Swing upward to remove.3. Remove 4 screws from the wooden panel in center.4. There is a "black box" in the very front of electronics. It will have torque paint on the 2 rows of 3 screws. top row is labeled "focus"MY TV would go green before going black. Volume still worked.5. I turned the center bottom screw (marked "green") appx. 1/8 to 1/4 turn COUNTER clockwise.Plugged TV in and it works fine.

Its either blue tube or bad componet on blue CRT board hertes how to know disconnect Blue CRT board connect to neck of blue tube turn set on see what happens if set come on and plays then this lets you know if it is a problem with tube/video ic on crt board. If set shuts back off different problem.

Hi Jimmy,Have you try using remote commander? It seems the power button on your tv is broken. It could be on button pad, or cables connected to it. Can you try check it?Regards

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 http://www.tvrepairkits.com/xcart/product.php?productid=19971&cat=1538&page=1 hope this helps good day and best regards.

The Blue CRT is needing replacment this is the type your model uses CR 07MVC41(B)-L(VM)

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

• Screen looks 3D
• Colors don't line up
• One or more colors can't be adjusted when using the convergence menu.
• Screen is bowed or warped.
• TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.

Here are some images of convergence problems.

This is for if the lines are thin and arc.

You need to turn down the screen voltage for the blue and red CRT. I don't remember if the focus block is in the front or in the back of the tv on this model. Most projections have them in the front.

You could check the back access panel and look for a black box with six knobs as descibed in step 3 below. This is what you are looking for.

follow the steps below if it is located in the front:

1) Remove the front grill
2) There should be access panel you need to remove once you remove the front grill. This is where the screen voltage adjustment is located
3) Look for a small black box with six knobs on it. One row is for "Focus" and one row is for "screen". It will be marked, but probably need a flashlight to see which row it is. There will be a "R", "G" and "B" next to each knob to represent Red, Green Blue respectively.

4) Careful with the access panel removed, you are only inches away from very dangerous voltages.
5) slowly turn the R or B knob counterclockwise until the lines on the screen disappear.
Keep your hands away from everything else and only use one hand near the tv. put the other hand behind your back.

6) Once corrected, replace the panel and put the grill cover back on.

You need to turn down the screen voltage for the blue and red CRT. I believe the access is through the front on that model.

1) Remove the front grill
2) There should be access panel you need to remove once you remove the front grill. This is where the screen voltage adjustment is located
3) Look for a small black box with six knobs on it. One row is for "Focus" and one row is for "screen". It will be marked, but probably need a flashlight to see which row it is. There will be a "R", "G" and "B" next to each knob to represent Red, Green Blue respectively.

6) Once corrected, replace the panel and put the grill cover back on.

This can be an indcation two things 1: a defective focus/screen block or 2: a defective CRT if the lines are of one color then it is that color CRT. in any event you will need to have a tech work on this, doing this repair yourself can be very dangerous for you and the set.

Tv have a problems known as a convergence problems,it dead.Tv have colors lines R,G,B mis alignments,have colors shadows picture or 3D pictures look alike?The tv convergence board have dead 2 STK convergence ICS and some or all of it resistors too.These parts on the tv convergence board,must be replaced to solved the tv picture convergence problems.The shop,will cost u like $300-350 for parts and labors.

This is not a bulb issue it is a issue with the optical engine, a very expensive repair. I might not waste the money on this fix, 500-700 to start. Good luck

Hi,
This is symptom of bad/ defective blue picture tube that will be replaced to fix this problem.
Blue picture tube replacement is job of professional because it requires lots of convergence adjustments for correct picture and picture tube price would also be bit high.
Let me know to provide you blue picture tube part number info.
Thanks.
