Question about Sony KP-ER43M61 43" Rear Projection Television

Stain on screen

My two year old wiped the screen with one of those hand cleaner swabs handed out at restaurants after a meal. I assume it contains some alcohol or cleaning agent. It left a permanent mark on the screen which shows whenever the screen is dark. I tried removing by just wiping with a damp cloth and it didn't work. What can I do??

I have a 40" hdtv that has a blue hue in the middle, kinda looks like an "UNDER ARMOR" design. What is this from and can i fix it.

Sounds like the coolant is old. Projection sets have 3 tv tunes in them red, green, blue. They are coupled to a magnifying lense via a coupler that contains an antifreeze type fluid that helps dissipate the heat. Over time that fluid gets old and breaks down and often results in dark spots on the screen. The stuff is toxic and a pain to replace. Best to call a service technician. Before doing that I would carefully access the tunes and spray window cleaner on a lint free rag or towel and wipe off the lenses...just to be sure there isn't anything on them..especially if you or a previous owner smoke. Make sure to allow plenty if time for it to dry and never spray the cleaner onto the lenses.

How to clean your dlp tv screen?

1.Check your TV to see if it has a screen shield. TVs with a screen shield are covered in protective plastic and are much easier to clean than those without them. Look at your screen and see if it appears to be smooth or bumpy. If you still can't tell, touch the screen lightly with the tip of one finger. If it has a shield, it will be hard and rigid; if not, it will be soft.

2.Clean a DLP TV screen that has a screen shield by wiping it with a dry microfiber cloth. Start at the top left and move side to side until you've covered the whole screen. Use gentle pressure and touch the screen only with the cloth, never with your hands. If just using the cloth doesn't get out a stubborn soil spot, dip the cloth in a bowl of distilled water that is at room temperature. Wring out the cloth and try wiping again.

3.Clean a DLP TV screen without a screen shield only with an approved screen cleaning kit. Your best bet is to purchase one directly from your TV's manufacturer. However, you can also find generic kits at most electronics stores. Each kit comes with a cloth and cleaner that will not damage the delicate screen. Follow the same side to side method to wipe the screen as outlined in step two. Again, avoid touching the screen with your hands.

4.Avoid letting liquid sit on the screen. Since you shouldn't use much, it should dry quickly. If it's still wet after two minutes, use a second microfiber cloth to dry.

Need to clean color weel

To clean the colourwheel do the following.

Soak cotton swab in denatured alcohol

Using a circular motion, swab gently one color area at a time

Use dry swab to remove film build up.

Repeat to ensure the wheel is thoroughly cleaned

DLP color wheels need to be cleaned approximately every six months to a year, if the environment they are placed in is smokey, greasy or dusty. Sometimes, restaurant owners or places with high customer traffic will find that their TVs are experiencing picture degradation due to the smoke-filled rooms or greasy fumes from kitchens. There is no need to replace the color wheel but just to do a quick cleaning to save money on replacement parts. Even if you have your TV at home, your DLP color wheel may require a cleaning occasionally to provide clean picture quality.

Blue dots center and yellow stain right hand corner on 60'' sonytv

Yes, I do. It needs a new light engine. Very costly repair. However, Sony has extended the warranty on many of these LED projector sets. You need to call a local Sony authorized service center and see if your model is covered. Otherwise this repair could run over a thousand bucks.

Cleaning screen on my 1080i hd panasonic????


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 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 ******* 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.
