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.

Dark smudges/spots on my HDTV screen


The model indicated here Sony Grand WEGA KDF-50WE655 is a LCD rear projection and rarely if ever requires cleaning.

If black spots or such are gradually appearing the issue on this model is the optical light engine.

Set uses a LCD engine which the lamp shines directly into and heat from that very hot lamp can damage sensitive baffles inside the engine.

I would suggest also you contact Sony as they have on several models extended the warranty for this kind of issue---Engine is very expensive part and several of these Sony sets were involved in a class action lawsuit--hence they are dealing with them.

Do not take no for an answer if you want them to help you---the hinge that is sqeeks gets oiled...........

Much like anything in your home, TV screens get dirty with fingerprints and dust and require a periodic cleaning. Keeping your TV screen clean is essential for ensuring a clear picture. However, cleaning the front of your TV is not something that should be left for the cleaning lady. The use of certain cleaning products and solvents can damage the front of your TV screen. Special care must be taken in order to make sure that your TV screen is cleaned properly.
Every kind of TV has different steps for proper cleaning. If you are unsure what kind of TV you own, consult your TV user's manual to ensure that you are using the right cleaning method.
  • Direct-View - Older direct view TV's can be cleaned with glass cleaner and a paper towel. Newer tubes that may contain any special coatings, like an anti-glare coating, should be cleaned with a damp cotton cloth. If you are unsure if you have any special coatings, it is best to be safe and use the damp cloth.
  • CRT Rear-Projection - Before you can begin cleaning, you need to determine if you do, or do not have a screen shield. A screen shield is a hard plastic cover over the front of the TV screen. If you can't tell, give the front of the TV a light tap. Another way to tell is to check for ridges in the screen area. If you can feel ridges on the screen, then you do not have a screen shield. Rear projection TVs without a screen shield require a special kind of cleaner and rag. These are available for purchase at your local TV service center. Those that do have a screen shield should be cleaned with a dry or damp soft cloth. If it's extremely dirty, a mild soap may be used. Do not use paper products, such as paper towels, to clean the screen shield. Paper products GA_googleFillSlot("TL-IMU-Article"); b3342371.3;abr=!ie4;abr=!ie5;sz=300x250;ord=[timestamp]? can easily scratch the surface of the shield. Screen shields can have a tendency to streak while cleaning. If this happens, use a dry cloth and buff the screen in a small circular motions.
  • Microdisplay Rear-Projection - All microdisplay TVs have some sort of screen shield on the front. These TVs should be cleaned with a damp cloth. Microdisplays with a shiny screen shield can be cleaned with a mild soap if extremely dirty. Those with a flat screen shield should not be cleaned with any cleaning agents. Do not use paper products to clean the front of the TV because they could scratch the screen surface.
  • Plasma - Plasma owners should clean the front of the TV with a soft, damp cloth. The use of a mild soap for heavy cleaning is acceptable. The use of heavy cleaning agents could strip the special coatings on the screen, and paper products can scratch the front of the TV.

  • LCD Flat Panel - Be careful with flat panel LCD TVs! Use a slightly damp soft cloth to clean the LCD screen, then immediately dry with a soft cloth. Do not press hard on the screen during cleaning. Doing so could cause severe damage to the display. Do not use any cleaning solvents, such as glass cleaner or soaps, to clean the LCD screen. Paper products could scratch the front of the screen. If you have a pet or child that rubbed something on the screen that you feel could stain or damage it, contact your local TV service center for assistance.
When dusting the TV cabinets, dust with a damp cloth or a mild cleaner. Paper products can scratch the surface of high-gloss cabinets, so avoid paper products. Heavy cleaners can strip the finish off of TV cabinets over time. When cleaning speaker grilles, dust with a dry cloth. Wet cleaners could stain or damage the grille cloth.

I fixed it!!!! If you can open one of the sides (on the JVC there is a little door with a screw), then you can clean the projector lense in the middle on the bottom. It kind of looks like a big light bulb. It seems there is just dust on the glass that is projected onto the screen. We had a big gray spot and cleaned it with a damp glass cloth and Ouila! It disappeared. I scored MAJOR brownie points with my husband for this one! He wanted to replace the TV!

Mitsubishi tv model wt 46809


Good Day, sam;
Sam it depends on "smudge".
If it's an oily type; then a mild soap, like dawn, on damp, warm soft cotton type cloth may remove it.
There are products found in most large best buy, circuit stores that sell a screen cleaner. It's sold in a small spay bottle, about 2-3 ounces. Always spray onto cloth NOT screen. Always wipe/clean with up & down strokes, NOT side to side or at an angle.
If the screen is smudged after attempts of trying to 'cleanning' a scratch, then only replacing the screen will fixya problem, cost will be in the range of $100.00-$250.00.
Good Luck, hope this was helpful, big IRISH.

Dark Blotch on rear projection TV screen


usually these are caused by cleaning the screen with a damp cloth or fkuid rear projection tv's usually have two plastic screens separated by about quarter inch with bulbs between,one being a magnified screen.problem is,condensation can occur causing various blotches,letting the screens naturly dry out usually solves this but failing this you have to strip down and wipe them with clean dry cloth.be careful though the inside screen is very delicate.
