To clean the dust inside the screen, you will have to disassemble the LCD panel. It is a very risky job and there is every chance of damaging the LCD screen unless you have a real good experience of doing it. If you are not good at doing such jobs, please let some professional do it for you.
First easy thing to try is unplug the TV from the power for about half an hour and try it again.
If no luck;
Do you get the same effect if you unplug the cable box from the tv completely? what about if you are watching something from another source - DVD player or VHS or PC or similar. Do you get the same?
Could you post back a photo of the green dots etc? may help us to diagnose the problem.
Do you have a model number for your set - it doesn't seem to have posted?
awaiting your info :)
The most severe problem dust can cause in an LCD TV is a short circuit. This occurs when dust enters the television's casing and settles on one or more of the internal circuit boards. Enough dust can cause a short circuit, which will prevent the TV from working at all. In other cases, it will damage picture quality or prevent certain features from working properly.
Because a short circuit can only occur when enough dust is present inside the TV, this problem happens after the TV has been in use for a number of years, meaning that it will not be covered under the manufacturer's warranty. In many cases of short circuits, repair is expensive, and you are better off buying a new set.
Dust can also have an effect on an LCD TV's picture quality without entering the LCD's casing. Dust that settles on the surface can distort the picture and decrease its brightness. While it's easy to wipe the dust away, use only a soft cloth and mild cleaning solution to avoid scratching the screen or causing permanent damage with caustic cleansers.
Dust under the screen can be more difficult to clean. Using compressed air to blow the dust out is the best option, short of disassembling the set to clean the screen from the inside. Keeping the surface of the screen free of dust is usually sufficient to prevent dust from getting under the screen.
Another effect dust can have on a an LCD TV occurs when it enters the space around buttons, making it difficult to control the television. On certain sets, dust will cause buttons to stick or prevent them from engaging when pressed. Using compressed air to blow the dust out, or resorting to using only the remote control, will solve this problem.
well u have stopped ur movies(dvds) to many times and the dots are burn marks on ur screens if u read ur manual it will tell u NOT to leave a still picture on for to long as it will damage ur screen i assume u have a PLASMA TELEVISION if not... sorry cant help u
1. Do you smoke? (if so, this is why)
2. How old is the lamp? (over 2yrs, this is why)
3. dust, construction, stored in garage?( if yes, this is why)
DLP is basically LCD. LCD doesn't dim so this is not likely (but possible). Normally is is caused 1,2 or 3 above. After that you can try looking at the area where the lamp goes in. If you notice dust on the glass thing inside the TV (not on the lamp itself) you can try cleaning it off. USE DISTILLED WATER ONLY NOT CLEANERS. This mirror inside the TV behind the screen could be fairly dirty but honestly if this is dirty you have bigger problems so this is probably not a cause.
Well i really do not know what that is but i do have a thought it could be a bad connector and if you want i have the same tv for sale for $300 shipped just for parts the problem with my pt501 was the screen turned colors but the lamp is in excellent shape and so is the lcos screen the ownly thing that does not work is the main board (ciruit board) i will send you the hole thing for just 300$ shipped if you'd like email me back email@example.com
