SOURCE: How to change CRT in Sony KP-57WS500

CRT is expensive!!! Try to shuffle the electronic parts driving the CRT tubes first, it has three sets of parts, all are the same in each color: red, green, blue. Sometimes cleaning the leads or metal parts of the circuits, specially the green region, will gonna solve the problem. Do it first, it wont gonna cost you a dime, just time. [:0)

Hi Guys

Your problem here has to do with the amount of aging that happens to the three colour tubes - red, green and blue.

Blue actually ages slower than red and green. What actually happens is the green tube deteriorates and due to green being the predominant colour for brightness causes the blue tube`s flyback lines to appear - especially when switching between inputs or when the video is blanked.

No replacing the blue tube will not solve your problem as the tube is actually the best one of the three.

As someone mentioned there is a way to adjust this by removing the speaker grill assembly in front of the set. Doing the service mode adjustment with the remote is not the right way to solve the problem - you would be adjusting the colour gain and off-set values and would seriously be compromising the white balance of the set.

On the left hand side behind the speaker cover you will see a black square block with six adjustment points. Look for the one marked SCR BLUE, Switch the set to a unused input so the blue lines become visible. Now adjust the BLUE point counter clockwise until the lines disappear. A small adjustment should do it, Switch back to a picture and make sure the whites are still white.

This should sort your problem. I would however suggest asking a Sony service centre to do this for you. This is a dangerous thing to do as you will be working close to the 35Kv supply the the anodes of the three tubes.

I hope this answers your question.

Goo luck.

SOURCE: Sony KP-51WS500 Rear Projection TV colors are distorted.

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.

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.

hi, you`ve lost your convergence ic`s, unless your very proficient at solder work I`d advise you call a tech, will require removing 2 large IC`s and possibly a few small support parts, resistors, chemical fuses etc. Every place is a little different but runs approx. 300.00 at my shop, gl, video-tek

I have a sony color rear videoprojector tv model kp-57ws500 that when i turn it on its blurry and video or dvd word is red blue yellow almost like in triplicate. after about 45 min. it clears up and works...


If your TV looks 3D, warped, or distorted it likely has a convergenge problem.
If however it just looks dull, washed out, redish, or if it looks like objects on the screen have halos the fluid in the lens has soured.
You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com

I have a KP-57WS500 and when it is turned on the screen starts to turn blue and after a few seconds the entire screen is blue. After that happens the TV will turn off.


This link has the instructions on how to fix this problem and other similar problems. You
have nothing to lose, so I recommend that you try it.

This works with the two other colors, blue and green also. Not all models of Sony Projection
TVs have the red, green, and blue pots in the same order as the picture that is listed on
this link, so you may want to google search for your model's service manual. The service
manual can also help you be able to remove the cover for your particular model of TV. I was
able to find the service manual for my model, and sure enough, the order of the pots are
reversed on mine, so I would have been adjusting the wrong color. Read all of the comments
on this link too, because you can find other helpful tips and may even find someone with the
same model of TV as you that gives more specific instructions for your model.

You may also find your model's service manual here:

P.S. You can also clean the mirrors and dry dust while you're in there which can help with blurriness and focus.

Tv comes on for a few minutes then goes off


If you take off the front bottom panel of the tv wich is easy. Then you will see 6 tuning knobs at the bottom middle of the tv .the top 6 control contrast for the lights dont mess with those. the bottom 3 are the power to each light.red is bottom left if your screen went blue it makes sense that the red is starting to go but if you turn down the power to it left 1/8 turn it should fix it for awhile .Its easy.
