Red 2 inch streak in middle of television screen

Hello i had the convergence problem fixed and the television works great again.I cleaned the lenses with a soft cotton cloth and lense cleaner and dusted cob webs.For some reason now in the middle of the screen is a 2 inch streak horizontal that looks like someone made a marker line. I cannot figure out for the life of me why or whats causing it. Have any ideas? You last answer was right on. Thank you.

use toothpaste rub a small amount on the scratched lens depending on how deep the scratch is rub the toothpaste over the scratch until the scratch is repaired.
Glass lenses are delicate and can be easily scratched.
These scratches mar vision beyond the lens, and can sometimes obstruct vision completely.
Prevention is the best method to keep glasses clear, but accidents can occur.
Luckily, there are several ways to quickly and inexpensively remove scratches from glass lenses.
These methods include using toothpaste, baking soda, windshield fluid and vehicle wax.
Apply a small amount of toothpaste on a soft, cotton cloth.
Rub the toothpaste onto the lens using small, circular motions.
Continue wiping for about 10 seconds and rinse with cold water.
For deep scratches, the method may need to be repeated.
Mix two parts baking soda with one part water to form a thick paste.
Use the cotton cloth to apply the paste to the lens, rubbing in a circular motion.
Rinse afterward and dry with a separate cloth.
Once again, this step may need to be repeated for stalwart scratches.
Apply a small amount of windshield fluid to a soft cloth, and polish the glass lens for several seconds.
This is more useful for light scratches, and is usually not effective against deep, prominent blemishes.
Use a clean cloth to buff vehicle wax onto the glass lens, once again moving in a circular motion, and continuing until the scratches have been removed.
Use several cloths, as the wax can adhere to the fabric, marring its performance.
Purchase an eyeglass polishing kit from a local optometrist.
These kits usually contain a polishing fluid and a soft cloth.
They are ideal for removing scratches from small glass lenses on glasses, cameras, telescopes and more.
They can be purchased for $10 to $20 and include easy-to-understand directions.

Daewoo DV-6T999B DVD/VCR Combo DVD player has suddenly stopped recognizing DVD's that it has played in the past, or new DVD's. It tries to load and ends up saying Bad Disc. There is nothing wrong with...


The step after using cleaner solution and disk is cleaning the pickup lens inside the DVD.
You need to disconnect device from power and remove the case.
Find the lens, that is the glass lens and under the DVD clamp.
Use a cotton swab and some isopropyl alcohol to gently wipe the lens.
Here is the complete procedure.

If it still does not work, you will need to replace the laser lens pickup that is the part below:

How to remove unwanted scratches sunglasses? Brand


  • 1

    Put on a pair of plastic gloves and smear a thick layer of Armour Etch etching compound on your sunglass lenses---the tops and the bottoms of the lenses. Leave the Armour Etch on the sunglasses for five minutes and then rinse it off under the faucet with cold water. You can find Armour Etch at any craft store. It is designed to be a fast acting etching compound and works great for getting rid of scratches.

    Spray lemon Pledge furniture polish directly on your lenses, both front and back. Rub it in with a rag. Wash the sunglasses with dish soap and water.

  • 3

    Spray the liquid Band-Aid on the sunglass lenses being careful to wipe off any excess with a paper towel. Let the liquid dry and then wear your sunglasses.
    Liquid Band-Aid is sold at pharmacies.

    Apply BRASSO furniture polish to your lenses and rub it in for three minutes. This product tackles the really stubborn scratches. Wash your lenses off with soap and water.

    Rub cigarette ashes in the scratches and then wash clean. You may have to do this more than once to completely get rid of the scratch.

    Use toothpaste. Apply a small amount of toothpaste on the lenses. Use a soft, cotton cloth to rub the toothpaste into the lenses. Use a small circular motion. The toothpaste will act as a filler and fill in the gap created by the scratch. Continue applying a circular motion for 10 seconds and rinse with lukewarm water. If the scratch is deep or stubborn, you might have to repeat the process.

    Use baking soda to remove scratches on your sunglasses. Mix 1 part water to 2 parts baking soda to create a creamy paste. Use the cotton cloth to distribute the paste onto the scratched lens. Use a circular motion to rub the baking soda paste into the lens. Rinse with lukewarm water. More stubborn scratches warrant a second application.

    Use windshield fluid. The windshield fluid will polish off the scratches. Apply a small amount of windshield fluid onto a cotton cloth. Polish the sunglasses with the cotton cloth for several seconds. This method is especially effective against smaller scratches but may not remove prominent blemishes.

    Use vehicle wax. The lipids in the wax will fill in the scratches. Apply a small amount of vehicle wax onto the cotton cloth. Apply the cotton cloth into the offensive scratch.

    I have a shadow on the screen in the bottom right hand corner what could the problem possibly be.


    It sounds like something has fallen or crawled into your tv. Unplug unit and remove the panel on the rear bottom. Now remove the upper part of the rear cabinet if you cannot see the problem. You will probably find something on the lense blocking the light. This would be a good time to clean the lenses. Using a soft cloth and windex, spray the cloth then gently clean each lense using a circular motion. Do not wipe until dry as you may scratch the lense. Do not spray the lense as you will cover critical components with corrosive cleaner. Do not push hard or disturb any lense adjustments. Reassemble unit and your tv should look as good as new. Let me know how this works out. hardrocko@hotmail.com .

    Cob webs behind screen


    The frame around the screen just pops off. Unscrew the plastic holders from the chassis frame and the screen will come off allowing you to clean everything inside easily. The "2" thin screens are easily cleaned and put back on easily also. Don't do what I did and think the screens go into the front slot of your plastic brace, they slide easily into the wider slot. You'll also be able to clean the dust from the reflector and guns with Windex. Much better picture after wards, trust me. You would be surprised how much dust may have accumulated on the lenses.

    RCA PROJECTION TV IS SO DARK ITS HARD TO SEE IN DAY LIGHT CAN I CLEAN IT


    When you say it is dark do you mean no contrast or some channels are dark while others aren't. While cleaning would certainly not be a bad thing you may also need to increase the crt drives if the unit is several years old. This is normal but unless you are familiar with the unit you could do more harm than good. Cleaning the lenses would be an easy first step. Unplug the unit from the mains. Remove the rear cover. You should be able to see the three lenses. Using a clean soft cloth spay a small amount of general purpose cleaner such as windex on the cloth. Using a circular motion clean each lense being careful not to move any of the focus adjustments on the lense assembly. When you have all three lenses clean reassemble unit and test. If this was your only problem you should have a better picture. If the unit is still too dark you should have a local technician adjust the crt drives. Good luck and be careful!

    Can I clean the color bulbs on my 52'' RCA television?


    To clean these lenses is easy with a clean soft cotton cloth in a kindly way. BUT wait a minute: To get access to those lenses is the really hard job. something as you want to see the core of an onion but tobe there you have to take a cover at the time. Trust me: Literally. Step by Step, at least 40 screws. the front screen is the last step, and then you can see those lenses. If the tv is working OK and is the only job needed, ask a technician for a regular cleanning and adjustment you can get surprised about the service cost (NOT REALLY HIGH i mean). make sure he cleans the back mirror also.

    FUZZY PICTURE CONVERGANCE IS GOOD


    Hi There!
    You can certainly clean the mirror and lenses. surgical alcohol and a soft cloth should do the trick. Be careful when removing the screen. It is fragile and the slitest bump can damage it permanently. Also be careful not to turn or bump the lenses. Thus can result in many hours wasted on realignment. Good luck, JUS004

    Error message


    *&%$@#%^&*&^% !!"It's working!!!! Turn your camera on and put it near your ear. Did you hear a softly motorized sound in the lenses area and the green LED is flashing? If you hear this sound do this. Do it under your own responsability. (any way your camera does not work). When you turn on the camera wait until the lenses come out, in that moment grab the lens with your hand and don't let it go back. The camera will turn off but the lens will stay out. With the camera off push in the lens with your hand. Turn on the camera and that's it. I had to do it 2 times, but now my camera it's working again. This system error could be caused because the lens get out of it rail and the camera can not set the focus system.
