Your TV most likely has one or more 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.

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.

Ajusting didnt convergenced in the corner of mitsubihi tv


Have worked on a lot of these sets. A number of possible reasons:

1. Slightly damaged convergence IC.
2. Someone has in the Tech menu tampered with the green which affects corners and geometry of the picture---not easy to correct in most cases and usually is bottom corners but can be top.
3. A problem in the Digital convergence block which includes caps and or the 3 chips for memory.
4. If only a single color will not adjust there(look at green first to see if grid of lines are straight---red and blue are adjusted to green and if green off may not be able to line up with it.
5. If large sub woofer near it on side affected move it away---if its been there a while may be magnetized -=--rare.

What I would do is go into Tech menu or customer menu and call of the grid of lines (advanced in that menu) and carefully look at the area affected.

If one whole side will not adjust--chip bad most likely= if just a corner geometry off.

A lot (almost all) were adjusted for Geometry with a special unit at the factory and it can be nearly impossible to correct even in the Tech menu which can be accessed with a 4 number code and the original remote---advantage there is it SAVES adjustments to memory of the set for this.

Number code a specific one for each model group.

If need the numbers for yours confirm model number as I have a list of them available.

I finish by saying if need more help or have a better description let me know.

What are the default geometry values for 480P and 1080i FULL modes?


If you have the model listed have fun----Geometry values are depicted in the Convergence section---the grid of GREEN lines determines geometry and red and blue are then adjusted to the Green.

Primitive: Set had at one time two overlays available--clear plastic you attached to screen to line the that Green grid up against---one for 480 and one for 1080.

Once the geometry is set (best possible) you must align convergence and save it in both the modes one at a time.

By current standards a Fred Flintstone system--but in its day a real pain as alignment can take many hours with the correct remote via the tech menu for convergence.

I have a Phillips TV Model No. 46PP93 0217. The


Projection sets have two very common problems.

The first common problem is convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Sony kp51hw40 has green shadows and on edges in pictures and blue flickers on and off, tried all adjustments including screen, focus, and menu??? no luck


The CRTs in this model of TV had a problem with internal leakage. The blue was usually the first to show the symptom (flicker). Because all 3 CRTs are connected to the same high voltage source, when 1 acts up, the other 2 suffer as well. You need to replace the Blue CRT. However, this TV has some age on it... 1 tube will lead to 2 tubes, and 2 tubes to 3... They only last about 7 years. If you love the TV, replace all 3 (about $200 each). I recommend replacing the Red and Blue first, adjusting the geometry and convergence to the original Green. Then replace the Green, adjusting the geometry and convergence to the new Blue and Red.

Mitsubishi TV Model #WS65903 - Green Shadow Lines on Screen


Something is not right here--The green is adjustable in the TECH menu--did this person adjust or try to adjust in the customer or the TECH menu?

If you confirm actual model number I can tell you how to get into the TECH menu--yes--green will not adjust in customer menu--it determines geometry and is only adjusted in the TECH menu.

Also, this set requires any convergence adjustments to be done in 480 and then in 1080--if only adjusted in one mode the other will still be bad.

Let me know if you know how to adjust in TECH menu or not--with exact model number I can tell you how to get there.

If this helps you rate this solution as I do this here for free.

Red shadow figures


If you go into the customer menu with the Mitsubishi remote and the colors are skewed or will not adjust:

If red or blue will not adjust in some direction--you have a Convergence circuit problem---

This model (WS-55809) uses two of the STK-392-570 Convergence IC's---

Green for a good reason is not adjustable in the customer mode---it is only adjusted for the Geometry or straightness of the picture and then red and blue are adjusted to it.

If you are able to do this repair yourself you can save the set and a lot of money---most shops charge 300-400 for this type of repair in this set.

You can buy both chips for about 14 dollars on Ebay- and I have step by step---start to finish instructions for this repair in this set--they tell also everything you will need to do and what you need.

If you want the instructions let me know---I am not allowed to post MY email here...but I can post the instructions here.

Not everyone can do this repair---Let me know if you have any questions or need advice----

If you get someone else to do the repair make sure BOTH chips get replaced or the set will have the same problem again in a few months.

This problem should be fixable right in your home--I have done hundreds of them and have two sets to do this type of repair on tomorrow.

Philips 55PW9363 need convergence grid dimensions


You may not need a template as long as the geometry has not been totally lost or corrupted. How is the image in red and blue? If any of the three convergence/CRTs has good geometry, you can align the others to it. You can simply cover over any CRT whose image you wish to block out while you are aligning the others.

Convergence


Touch-up Convergence adjustments Enter the Digital Convergence Mode (DCM) by entering 0-6-2-5-9-7-(Status or Index) on the Remote control. The following menu will appear: Select an active channel or Aux Input. A signal must be applied to the set when performing convergence. If any Customer Adjustments need to be made, the Menu button can be used to toggle between the Customer Menu and DCM. The MPOSD ADJUST is used to center the Customer Convergence grid. A highlighted cross will appear along with the Convergence alignment grid. The highlighted cross should be centered onto the center of the Convergence grid. To perform a Touch Up Convergence, highlight SELECTION and press the right cursor button on the remote. The following menu will appear: Selections STORE, RESTORE FACTORY, and RESTORE DEFAULT are not shown after selecting SELECTION. Press the cursor down button on the Remote for these selections to appear. RESTORE FACTORY loads Convergence defaults from the Factory Loaded section of the Convergence Memory IC. RESTORE DEFAULT loads Convergence defaults from the sets software. To perform a Touch-up Convergence: 1. Enter the Convergence Mode and select RED TO GREEN or BLUE TO GREEN. Do not select GREEN (Green Geometry) without placing a Template over the screen. To perform Green Geometry, refer to the Complete in-depth Convergence. 2. Use the Cursor buttons on the Remote to Navigate from one adjustment point to another. Press the Status or Index button on the Remote to select ADJUST. Use the cursor buttons on the Remote to adjust the Red to Green or Blue to Green. Press the Status or Index button again to navigate to the next adjustment location. 3. After Convergence alignments are complete, press the Menu button on the Remote to return to the SELECTION menu. 4. Highlight the STORE selection and press the right cursor key on the Remote to save changes. 5. Use the GREEN TO RED or GREEN TO BLUE selections to perform convergence when the Green CRT has been replaced.
