Hi and welcome to HDF

1. What is the make and model number of your display?

2. What HD source are you feeding it? (CBL/SAT, etc)

3. Are all the noise reductions controls turned off?

4. Where is your sharpness set at (give range like 20/100)

Sparkles can be due to a bad cable for the video. What cable and input do you have the source where you see these "sparkles" in the black areas?

Is it with all inputs and sources (i.e. cable or sat tv, DVD player, etc)?

Sometimes a digital cable CAN show sparkles on the screen. Try disconnecting it at both ends and reconnecting it again to see if a better contact helps. If that does not help, I would try the following to troubleshoot the problem:

1. Try another HDMI cable if you have one you could try?
2. Try using a differnt HDMI input on the display (it has has 3 I think) to see if it is the input on the display that is faulty.
3. Definitely turn the sharpness level WAY down on that Blu-ray input. Each input on your (very nice BTW) display has it's own picture setting memory.

BTW, which brand/model BD player do you have?

I just bought a new Toshiba 55" Plasma (PN58C500G2F) connected to DISH TV running it through HDMI cable.

Within a week of connecting it I started noticing sparkles as well. They appear to be related to the HDMI input, as they disappear if I view the exact same thing through the AV input.

I can get them to go away on the HDMI input but not sure what did it. I turned TV on and off and unplugged and plugged in HDMI cable (brand new 3' provided by satellite folks) and eventually they disappeared (just jiggling cable at tv input seemed ineffective). But they did reappear a couple days later...with same outcome as above. Did this a few times.

I just switched my cable to HDMI input 2 and the problem went away immediately. Not sure if the HDMI port switch is a permanent fix yet or what.

Wondering though if I should be concerned about having a bad port in my brand new TV and if I should return it or what. Hate to have 1 bad port right off the bat and then be kicking myself in a year when I want to use the port for something else.

Thoughts?

My first Panasonic ATSC tuner had sparkles. It was heat related. I put a PC chassis fan on the hottest area of the tuner and the sparkles stopped.

I had green sparkle on black with my Sammy-5084 and It was bad.
I tried different hdmi , Hd DVR boxes couldn't fix the problem.

Best bet would be to return it Darth

I had sparkles on my Panny G25 from my Panny BD65 player. I suspected the HDMI cable (which was brand new from monoprice). I checked on different inputs on the TV, and saw the same sparkles (mostly on black or dark areas). To someone who works with electronic equipment somewhat routinely, HDMI cables seem to seat in rather flimsily.

I tried a different cable I ordered with the same batch, and it seems fine, but I suspect the other one might not have been in as firmly as it should. As long as I make sure the cables are seated as securely as possible, I don't seem to see an issue.

If your sharpness is set to 75, that is BAD.

It should be near 0

Toshiba does not make plasmas any more, but that model number looks like it is a Samsung plasma. Is it a Samsung?

I would try changing the cable or even switching it around so the cable end going to the TV goes to the source device instead and have the end currently going to the current source end goes to the TV. This sometimes helps, but I suspect it is a cable issue or a defective TV.

As someone else said, for your model the Sharpness should be at ZERO so it doesn't add outlined borders on objects and make signal noise or film grain stand out more than it should with this artificial sharpness.
