Let me know when TV warms up does it go to standby?
If yes, standby light would be blinking, let me know how many times it blinks?
And if TV does not go to standby mode, does picture remain with red tone?

That blinks and flashing have a diagnostic code. I have a list of the problems that might have occurred indicated by the number of blinks or flash. Tim just post the number of flash or blink,so i give you diagnostic code meaning...

Hope it may help you;

hola al problema lo debes tener en los transistores de color que estan en en la plaqueta donde va el socalo debes tener alguno desoldado

You both have a bad high voltage Trippler block.

Their is only two possible things they are Bad Red picture tube or video ic on red CRT board more then likley its your Red Picture Tube.

Hi,
To clean its front screen, you should not open front cover as its complicated procedure. just take off its back cover as its shown in picture and use air-blower to clean dust. Then use soft cotton cloth to clean its screen from internal and 3 bulbs / lenses (CRTs) and job is done.
Need further help, let me know.
Bye.

To Fix.. The Buzz.. The noise comming from one of the Board Inside. Open it and see..Or call a tech..

Based on service manual info, it cant blinks 7 times as per symptoms, please count again blinks. It can be 5 times.
If its 7 times blink, Horizontal Deflection stopped in this case. If you want to repair it at your own, please let me know to guide you further but it is necessary you should have knowledge of electronics.

Your TV requires Geomatirc Adjustments in proper manner by qualified servcie person.

5 times blinks shows problem of White Balance Failure in TV.

Your TV most likely has one of two possible problems.

Problem #1: Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem

• 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.

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 directions your convergence chips are bad and should be replaced. This is a common problem.

Solution #1

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.


Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

Solution #2


What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Obviously the TV needs to be serviced, if you plan on trying something yourself be carefull and please note- If still under warranty or if you have no electronic repair experience you should take the set back to the shop or to a repair person. Some of the solutions described below can be dangerous, TV's are very hazardous to service. Even when plugged out, TV's can store very high voltages. Suggest ESR all associated caps and change the audio output ic. If you're not sure how to go about that and you have some soldering skills I suggest that you first of all check for any solder defects in the area, and resolder if necessary. Still, If the sound coming out of the TV speakers while not connected to the stereo is OK, then you're looking at something else. Good luck

For the guy witht he problem w/ the blue tube. It probably isn't your tube. When you take off the front panel, and the board behind it. you can see the bottom of the tubes. The light on the bottom of the tubes says that your heaters are good; thats a good thing. Below the tubes is the focus block, where you can make adjustments to the tube intensity and focus. If the tube won't adjust in then replace that focus block and you'll probably be fine. For the other guys, the transistors may or may not fix it, but your definitly going in the right direction.

Look in the menus for the convergance adjustments. It sounds like red is out of adjustment.

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.
http://www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html

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.

From comments at this blog on how to fix lines across Sony Projection TV:

Comment1:
To remove the cover on the KP57WV600, remove the 5 screws behind each of the speakers. Then pull out the bottom center of the grey panel. It is held in by 4 snap type pins. The cover hinges at the top. Rotate up and be careful not to pull out the wires connected to the front panel. Then proceed as directed here.
Comment2: For those with KP-xxWVxxx TV series you need to remove 5 side screws, just behind the faceplate covering the speakers, next - pull out the 4 round-shaped clips on the botton of the faceplate and last - push-in the top part of the faceplate & pull down at the same time to dislodge the 4 large flat-shaped clips on top.

Comment3: My model required me to removee the 5 screws on the rear facing side panels (LH and RH lower facing aft) then with moderate force grab the lowest edge of the gray front face panel and pull out towards your self. Gently supporting the weight of the panel since there are slotted alignment pins at the top of this panel.

Hope this helps! :)

According to several sites, the problem is with the convergence via the voltage on the color ray gun tubes that get out of adjustment. They are also known as retrace lines

Sony wanted between $150-$300 to diagnose and fix -- instead I was able to complete this repair in less than 15 minutes!
Since I had been through the routine once more and I was sure others are running into this issue,
1. All you need to complete this guide is one flat-head screwdriver and one Phillips screwdriver as well as a delicate touch.
2. Front shot of the television. Their are two screw holes on the front of the unit near the edge of each side right next to the speaker grille.


3. Close up shot of the screw hold. It is covered by a plastic cover that has two tabs holding it in. Carefully pry them out with your flat head screwdriver. Do not apply too much pressure or you can break the tabs off. Once the covers are removed, unscrew the two screws with a Philips screwdriver.


4. To remove the cover, pull from the bottom of the front case and rotate towards you. Once you rotate it out, the top will disconnect and come loose. Do not pull it off, as there are cords attached. (see picture) Loosen the cables attached with the twist ties and set the front cover to the left side.


5. With the speaker grille and cover removed, you now need to remove the wood panel to expose the inner electronics on your Sony HD TV. To do this, remove the four Philips head screws from the panel. Then, pulling from the right, rotate the panel off and the electronics will be exposed.


6. This is a picture of the inner electronics of your Sony Rear-Projection High Definition television. The little black box towards the front of the unit is where we will concentrate our time as it is the control for the voltage & convergence adjustment.


7. When focused in on the controls, you want to concentrate on the bottom row for the voltage / ray gun projection adjustment. The colors are labeled below and from left to right are blue, green, and red. Choose the one that needs to be adjusted and turn ever so slightly with your Philips screwdriver to remove the lines. In my case, the red just needed to be turned 1/8 of a rotation to be back in adjustment. Do not turn to quickly or abruptly or you could possibly damage your TV by varying the voltage too quickly.
I hope this guide worked for you?
