Everything working fine, then home screen no longer displays on TV. On startup, pink dots go across TV screen, then TV goes black. Signal from most recent input is not coming trhough the audio or TV.

Connect the "bad" monitor to the VGA-out port on a notebook/laptop computer, to see if it works normally when connected. If not, then the monitor is "dead".
If it works fine, check the "screen-resolution" of the computer's video-card, to see if the values exceed the capability of the monitor.

screen drive on back of the screen has gone. they do over heat. the pink is the plasma lighting. replace the screen driver board and should be fine, when replacing put a bit of heat sinc on the top of the 2 or so chips big square ones on the board should help it last longer.

Looks like the display has developed some problem. Try changing the input device to some other like a DVD player, VCR etc. If the problem persists, this might require attention by a qualified service technician.

Heard aloud pop and my screen went black.

Buy another HDMI cable.Try another HDMI cable with another HDMI hub on the tv port.If u still have the same problems,mean the whole main tv Tuner signal board have problems and the caused.Tries websites like Shopjimmy.com,Ebay.com to buy a whole new refurbish tv Tuner signal board for the replacement.

Hi,It sounds like a problem with the color wheel or DMD board. The color wheel is a rotating disc that has a gamma of colors it spins at high rpms.The light of the lamp goes through it to create the colors on your tv.When it starts to go bad you will hear ,humming,buzzing,high pitch noises ,you might also experiment color distortion ,black and white picture. This is how the DMD works: http://electronics.howstuffworks.com/dlp1.htm Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screens. Here's a video that will help you find where the DMd chip is located : http://www.youtube.com/watch?v=0jr_9A5Xd2Q Have a blessed one!

I had a problem with the TV going on and off several times before "warming up" and then having pink dots. I would have to reboot to get rid of the dots. I called 1-800-SAMSUNG and reported that I had problems with the capacitors. That is what was causing the problems - cheap capacitors and Samsung is aware that this has caused many TV's to malfunction. My set was not under warranty but Samsung sent a technician across two state lines to fix my TV. As long as the problem is the capacitors Samsung will cover this service call 100%. My TV is fine now. BTW - capacitors which are sold in Radio Shack are not expensive. Why Samsung chose to put the cheapest Korean capacitors in their expensive TVs is a mystery.
So if your TV need warming up and has pink dots on the screen - call 1-800 -SAMSUNG and tell them your capacitors are malfunctioning.
