Green Pixles when TV should be displaying black or dark images

My 42" Polaroid LCD Television that I bought in 2008 is displaying green pixles when they should be black. It does this for both the TV connection and when watching movies on the DVD player. Both of these are connected thru separate HDMI cables. It does not do it all the time, sometimes the TV needs to be on for a couple of minutes before it starts. Does anyone have any idea what might be wrong?

SOURCE: No display, green light on ViewSonic VP201b 20.1 LCD

I have two broken VP201 monitors with different symptoms. One was black screen green light - like yours. The other was purple speks flying all over the screen., purple tint.

I swapped the power supplies and display boards, both monitors had original problems. I swap the inverters and the monitor which was black screen now appeared to work okay - but slightly pink and the monitor which was purple speks is now black screen.

I would therefore assume that both my inverters gone, one being on it's way out. You probably have the black-screen case.

Monitor going black after a few seconds can be caused by a faulty power supply or inverter. Some monitors have both as one unit.
Sometimes it is basic failed capacitors, After that then I would look at transistors.
The average monitor from 17 to 20 and sometimes the 22s have usually 4 bulbs in them. One bad bulb will also cause the inverter to not fire up.
Bad bulbs usually show pinkish tint, or flickering or are dark at center top or bottom of the display.

SOURCE: lcd tv with wrong color on one pixel

LCD screens occasionally have what are called "Stuck pixels". There is a tutorial in wikihow which might help you out here:

Try that and see if it helps. Stuck pixels are actually a slighty common problem.

Go to the setup menu on the LCD panel by pressing button 1 on the front. See if there is an option to reset the lcd to factory settings. Reset it and report if it helps not.

Green outline/shadow on dark images or backgrounds

LVDS Cable is corroded - This is the cable the provides video from the TV Video Process board to the LCD Panels Timing Control Board.

Honestly, if you can take the TV back do so. If not, Service it using the manufacturer warranty

Pink and green outline on people and text

How old is the TV?After a certain number of years the pixles will degrade and around key areas they will turn a rough color.Pink green orange blue,you name it.Otherwise It could be that it got damaged in a shipping process and then there wouldnt be much you could do except take it into the retailer where you purchased it and ask if the problem is fixable.

My polaroid has sound and picture problems

This is a well-known problem with many Polaroid FP displays. Eventually, the picture will simply go black, rendering the TV useless. The solution is a new control board, ~$400.

PDP-V401 Plasma

I am amazed it lasted that long. It could well be in the panel and would be expensive to fix. I think you would be better served at checking out a 40-42" LCD replacement. They've come a long way since yours was made.
