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.

SOURCE: Sony wide screen projection tv model kp-57wv600.

I found this solution from SONY's website.

The STANDBY light will flash if an issue is detected within the television. This can sometimes be resolved by simply following the steps below to reset the television.

  1. Turn off the television. IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.
  2. Unplug the television power cord from the electrical outlet.
  3. Let the television remain without power for 60 seconds.
  4. Plug the power cord back into the electrical outlet. NOTE: If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
  5. Turn on the television.
If the issue is still unresolved after following all of the troubleshooting steps, service may be required. Please note the number of times the STANDBY light flashes and relay that information to the service center.


I hope this helps.

Looks to me as an serious (but not uncommon) PSP board problem with Panasonic plasmas. Contact a Panasonic service center.

What problems have people had with quality control on these displays? Are they covered under warranty?

  1. Certain displays emitted an extremely loud buzz. This was covered by warranty repair.
  2. Certain displays had a problem with the Y/C delay on their S-video input. This was also correctable.
  3. One person reported red vertical lines on his display.Was this covered by warranty? Was it an input problem or a pixelproblem?
  4. Afew bad pixels here and there are not covered underwarranty. Largeclusters are generally covered. It's up to Panasonic'sdiscretion. Onthe plus side, however, bad pixels are becomingincreasingly rare. Mostpeople are reporting no bad pixels at all!
CALIBRATINGWhat needs to be calibrated on a plasma?
You needto calibrate most of the same things that need to be calibratedonother displays. About the only things that don't need to be doneareconvergence and geometry. You can usually tinker with picture sizeandposition, but there's no need to deal with keystone orpincushionadjustments, etc.What is white level? What is black level?How are they adjusted?
Theadjustment for white level is usuallylabeled "Picture" (as onPanasonics) or "Contrast". "Brightness", on theother hand, refers tothe black level. Yes, this is apallinglycounterintuitive. This FAQuses the terms "white level" and "blacklevel", since they betterdescribe what you're actually adjusting, andthey're the terms used byAvia and Video Essentials.
How do I adjust hue and saturation?
In anothermysterious choice of terms, hue is controlled by the "Tint"setting,and saturation is controlled by the "Color" setting. This FAQuses theterms "hue" and "saturation", since they're the terms used byAvia andVideo Essentials.
How do I set the white level on a plasma?
Youset the white level by adjusting the "Picture" setting. You willneedto use a different test pattern than you would for a CRT. Forbothplasma displays and LCD displays, you should use the 10 IREgrayscalestep pattern. There are two criteria you want to match on yourplasma.
First,you need to make sure the white level is low enoughthat your displayisn't thresholding (or clamping) bright levels. Youshould set thewhite level low enough that you can see each of the 10IRE stepsdistinctly. The Panasonics seem not to exhibit clamping (in mylimitedexperience), even at factory defaults, so this criterion may notbeterribly useful.
Second, for the health of your display (e.g.to avoid burn-in), you should turn down the white level. Just becauseyour display can display blindingly bright pictures doesn't mean that it should.Plasma displays should be set between 21 fl and 25 fl light output; thePanasonics comeout of the factory at about 30 fl. On one ISF-calibratedPanasonic, 23fl was roughly equivalent to a Picture setting of -20 (inthe usermenu, not the service menu). To set this precisely you'll needto bringin a calibration specialist, but you can do a lot of good byjustdialing down the white level a lot. After seeing the display at 30fl,23 fl will see very dim. But after a while, you'll find that 23 flisplenty bright.
How do I set the black level on a plasma?
Youset the black level by adjusting the "Brightness" setting. You canusethe same test pattern you would use for any other display.
How do I calibrate grayscale (calibrate the color temperature)?
Unfortunately,this is one you can't do yourself. You need specialequipment tomeasure the color. In fact, most ISF technicians lack theequipmentspecific to plasma calibration (a $15K gadget known asaspectroradiometer). But even the standard color measurementequipment(which calibrationists do have) will do a great job.
Thatsaid, one person who had his Panasonic display calibrated by anISFspecialist said that the Cinema / Warm setting was reasonably closeto6500K out of the box. Using that setting is probably the best you'lldoon your own.
If you're really determined to screw up yourdisplay,the RGB drive and cutoff settings in the service menu are usedto adjustthe color temperature.
How do I adjust the color decoder?
Thereareseveral issues here. Generally speaking, the Panasonic decoder seemstopush blue a bit. The R-Y Axis Angle and B-Y Axis Gain in theservicemenu are used to correct this behavior.
There used to beaproblem on some Panasonics with the Y/C delay on the S-video input.Seethe Quality Control section for more information.
How do I adjust the gamma?
On the industrialmodel, there is a set of Advanced picture settings. Goto the Picturemenu, turn Advanced on, and then hit the down-arrow. Inthe subsequentmenu you can adjust quite a few parameters, includingselect from a fewgamma settings.
This advanced menu appears to be missing from the consumer model.
How do I calibrate my consumer model given these missing menus?
Thereis apparently a way to activate these menus. Perhaps you can findacalibrationist or Panasonic technician would can turn them onlongenough to do the calibration.
What's the overall calibration procedure?
In general, the order Avia sets out is the correct one. A more complete list is:
  1. White level (picture)
  2. Black level (brightness)
  3. Repeat (1) and (2) until you have a good balance.
  4. Grayscale (requires special hardware and mucking about in the service menu)
  5. Sharpness
  6. Hue and Saturation (tint and color)
  7. Color decoder (requires use of the service menu)
  8. Repeat (6) and (7) for red and green until you have a good balance.
SERVICE MENUHow do I access the service menu?
In a word, don't. See the service menu warningabove.If you're bound and determined to make use of the service menu,buy theservice manual. It contains more than enough information foryou to ruinyour display and/or kill yourself.

I have recently moved my Sony 57" projection tv and the image is now blurry. I have tried adjusting the convergence manually but I'm no longer able to line up the crosses.

Adjust focus block, then adjust each of 3 lenses. loosen w/ thumbscrew, then turn cylinder to focus onto screen. Focus each by covering the others w/ typing paper, then tighten.

Sony 51" Rear Projection TV is blurry with colored ghost images

Thats caused by a convergence failure. The Sony type 1 convergence repair kit from www.tvrepairworld.com will usually correct that issue the kit contains the components and the CD with repair instructions so you can repair yourself.

The colors are separated. Images are blurry and

Try adjusting the convergence. If it won't move see below- (or hitting Magic Focus for some Hitachi’s)
This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$400 Be sure to vote/rate me if this helped Thanks!

Blurry Image

Congrats on changing the fly and getting it to come on. If it is a sony as it looks at the top of this page (accurate model?) need only to adjust focus and/or the horizontal static control. can't tell you where the horizontal static control is exactly but there are large wire associated. If not a sony then adjust the focus on the flyback.....top control bottom control is screen or for brighter picture.
