That is what is called BURN IN or as the manufactures call it "IMAGE RETENTION". Basicly what this means it that you have been putting more hours on the part that is darker the smaller part, or the 4x3 picture or the square part. And, basicly the part that appears to be lighter is "LESS" worn out than the other part of the plasma tv. There is no fix for the problem, But if you go into the menu and select "BURN-IN" OR "Pattern sweep" or WHITE Screen than you will see exactly what i mean. Now, you can keep it on this pattern overnight if you would like, but i suspect it will not cure the problem, but lessen the effects of it. But keep in mind, you are reducing the life of the complete panel when you do this. Not that it is bad to do this. If you have anymore questions don't hesitate to ask anymore questions. The better fix is to Switch over to the "Dish Network and than you can format the screen on any channel in any mode. Superior product to cable. Have a great day. And watch out for the snow storm coming. GURU JAY

My flat screen Sylvania TV is flashing different colors what's wrong


Better late than never. The problem is that your TV is in the service mode. There are many ways this can happen. But, lets just get down to fixin this! With the original remote and the TV on. If the TV will not shut off, do this. Press the left cursor button on the remote, followed with pressing the right cursor. Power off the TV with remote, or press off button on TV.

Secondly, your TV will power on and off. But you have flashing colors. Do this. With the original remote and TV on. Press the up cursor button, on the remote, followed with pressing the down cursor. Power off TV with remote, or press off power of TV. Thanks for asking me, Matt of Martins TV Repair.

I have a sony kp-53n77 rear projection tv i cleaned the lenses but i still have alittle to much red how can i clean up the color


Older projection set:

Not knowing exactly what it looks like I suggest two things: first in the menu look for convergence to see if it is off adjustment wise--it can be adjusted in customer mode to see if that helps.

Also either turn color all the way off (Black and white) to see what color the screen is with no color--if somewhat red you will need to turn the red screen control down--I can tell you where and how.

If screen is too red, red will be the prominent background color with color off or on.

Another easy way to LOOK is go to an unused video input---should only see "Input 1" for example in green and rest of screen should be black and not red to any degree.

Let me know with a comment here what you find.

Hi there, my dell projector 1800mp is not projecting an image on screen and it only black lines across. what should I do to fix it?.


After turning on the projector, press "+" and "-" buttons on the control panel

simultaneously for 3 seconds and release the buttons when screen goes blank.

2 Press "+" and "-" buttons again to exit the diagnostic mode.

3While in Self-diagnostic mode, the screen will run a seven-color-cycle test as

following:

Red--> Green--> Blue--> White--> Watchet Blue--> Dark Green--> Yellow.

Ensure that the colors of the test pattern are correct. Contact Dell if the colors are
not displayed correctly.

Red, green and blue colours diveded on my TV


ok well "tube" tellys as they are called use an electro magnet to keep the picture stable and colours correct its called gaussing now if you have a speaker or something magnetic nearby it will stuff up the colors but only normally producing colors like purple,green, or white
if you have colors across the screen (that aren't caused by magnetic force) then you need to take it to a repairer or decide wether or not to buy a new one this issue can turn out to be quite hard to fix and can be expensive the different colored electron guns may be burning or burnt out causing pale color or it could be as simple as a power transistor in the H.V supply has shorted out..and causing power issues to the tube.
hope this helps,ben

CRT green gun is not working properly , maybe dry soldered or no green drive signal. Pink and red colour is due to missing of green colour.

RCA CTC203 no red colour


Did you change the resistor by yourself? I am not sure if your TV has manual adjust on the back of the TV that you can adjust. Some times turning the TV Off and unplug it from the wall helps because it resets the TV. Check your Back ground color and see what is the dominating color. Blue, Green or Red. If this doesn't work please call a professional to look at it.
