We cleaned the inside of our tv and now we have a green screen

Please tell me how you actually cleaned it? Seems you may have hit something that turned the Green CRT gain up higher than the blue and red CRT?

Projection HDTV Pansonic 47" Curving blue and green colors on top and bottom of screen.

You will need to replace your two convergence I.C.s.They are two large IC mounted on a large aluminum heat sink.Replace both,look for any burned resistors near them,replace those if needed,and readjust your convergence. Good Luck

Let me know if you need any further help

Have a dark blotch on bottom right of screen. What is this? Transported in the rain and fear water got through carefully wrapped plastic. Help

It's possible the mirror has dome dust on it from jostling during the move. W dried water spot will do it too. The front screen will come off by removing the screws on the bezel. Be extremely careful cleaning the mirror.Any scratch by a cleaning cloth (never use paper) will permanently ruin it.

There is a green hue around the objects and people on the screen how do i fix this

Hope it is just cleaning take off the front screen. I think on that model remove the speaker covers, and a row of screws holding the bottom of the screen remove them. Watch the wires to the front buttons there may be a connector or two to undo. Carefully lift up and toward you WATCH THE WIRES. With a dry clean cloth wipe off the three CRT tops and the back mirror. Put back together and see.
If you still have a green hue.
Remove the screen again. With a flash light look down the CRT's if they a real cruddy down in the coolant yes there is liquid coolant in them. The red doesn't have this trouble but the blue and green can get contaminated. Also look for leaking of the coolant down on the boards. There are procedures to clean and repair leaks. Let me know.
There are a couple of focus procedures which I don't think is your issue.
Good luck Mark

Green screen

inside the light engine there is a red a green and a blue glass color filter.The heat from the lamp causes the color to burn off the glass.You need new filters .One is red one is blue and one is green.The lcd itself doesnt make the color,it is a black and white device.The colr comes from light shining through colored glass

Our Mitsubishi WD 52525 goes to blue screen and shuts off.

It sounds like you TV is overheating and the video is suffering and the lamp is overheating as well. Also, if your TV is over 2-3 years old, the mirrors (behind and below the big front screen) desperately need to be cleaned. Clean all filters and fans as well. (Look on side and behind the unit). Is the TV in a "hot" environment and/or dirty environment? DLP TV's are NOT sealed units. They need to be cleaned every few years to work well to have a good, clear, bright picture.

Green convergence on Panasonic PT-53WX42 is not ligning up...

Does not sound like the chips are bad.
What you need to adjust is "SKEW". You need to enter "service Mode" then go into "Coarse Convergence". Skew can be adjusted for all 3 colors. Unless you have the service manual, these corrections should not be attempted.

To clean the INSIDE of the screen, you really have to disassemble the TV. Remove all the screws that hold the "back" ( the piece with the mirror) to the front (screen) assembly.
The screen can be cleaned with a solution of diluted isopropyl alcohol, no more than a 50% solution. Drugstores will carry it, but it might be 70%-90%. Just dilute with distilled water (not tap water as it contains minerals). Personally I have used 70% with no ill side effects but 50% is recommended.

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.

there are two screens..the lenticular..and the can try to pull them apart(very fragile!) and clean them but you must be careful not leave any water or moister between them(blowdry or wipe completely dry after cleaning with damp cloth) do not rub too hard...just spray warm water on the rag and carefully wipe clean ...then dry. Putting the screens back together isn't too tricky but let me stress..these screens cannot be bent or they will break...pull them off with two people(one on each side)..also you will have to take the front cover off because the screens are literally clamped down to the front cover.....good luck...let me know if you need futher assistance..........mike
