Question about Sony KP-57WV600 57" Rear Projection HDTV-Ready Television

Screen alignment problem (overscan?)

I'm not quite sure what it's called buy my set appears to be 'zoomed' in about a quarter to half inch so that the top/bottom/sides are cut off slightly. I'm not in the TV's picture zoom mode either. It's very annoying when playing games since meters/health bars and even text is cut-off. It's been like this for quite some time. Flash focus seems to help a tiny bit but not enough.

A friend has this same exact television and the same problem so we are looking for some assistance. Thanks!

    Do I need any special tools to fix actual hardware or is it just a matter of changing menu items in the service menu?

  • twilightzone Aug 01, 2008

    I'm having the same problem with my set. I have the Service Manual (if anyone else wants it contact me I'll give it to you for free), but I have no idea how to use it. Can anyone tell me what adjustments I have to make to fix the overscan problem? Thanks.

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 shoScreen alignment problem (overscan?) - 2c07611.pngaced. 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.


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.

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.

This problem can be fixed by Geomatirc Adjustments in TV but it needs Service Manaul and knowledge of how to do adjustment.

    You dont need any spacial tools or change of hardware, it just need Service Manual and TV's remote control to perform adjustments.

Overscan


Yes, if you have the original remote and get into the adjustment menu which is hidden you can adjust width, height, and centering if you want.

Peoples heads are cut off on reg tv not in hd


Since your tv is cutting the heads off durring regular or analog signal but not high deffinition sounds to me like you have to set the aspect ratio different or such as going to your picture format from the main screen. Play with the settings from zoom, full screen, no overscan, cinerama and see if this helps.

Overscan is a staple in all CRT triple gun RPTV tech. It has to be taken in, if you want to see all of the picture possible in this medium. On ceiling mount front projection they have equipped them with all they need, they didn't need to do overscan, but with RPTVs this was not possible at the given price points. Overscan was necessary, to hide all the flaws out there at the edges, and they could not afford to pay their factory calibration techs to do it right, at the price points of the RPTV marketplace.

Unfortunately, when you take in that overscan, the picture gets hosed beyond belief, and then needs to be completely redone. It takes several hours and has quite a learning curve, a different one for each brand.

It is always available in my calibrations on all brands, but as an extra, at extra fees, to cover the extra time and experience/expertise required.

Sounds like a convergence issue. Call Sony for an ASC that can come out and give you an estimate. You are probably looking at $200-400 to do the repair.

Color problem


Did you try alignment of color convergence in setting up. Try this
1 Press MENU
2 Select SET UP
3 Select CONVERGENCE
4 Select screen mode ZOOM this accesses the center convergence adjustment.Press set/enter
5 Use arrow keys to aline the red cross to the white cross.Press set/enter
6 Use arrow keys to alingn the blue line in the same manner. Once adjustment is complete press MENU to turn the menu off.
I hope this helps if you cant move the red or blue lines you face the same problem I face. I still havent gotton any solutions to my post about being unable to adjust the red line.You could also call Pioneer's help line 800-421-1404.
