Question about Samsung HP-S5053 Television
Hello, I have a 50" Samsung Plasma. In the last couple of weeks, I've noticed millions of blue, red and green dots "raining" all over the picture. If the picture is small (with black strips on the side) the blue, red and green dots do not show up on the black, only on the picture.
This happens with cable, HD channels and DVDs.
The only thing we've changed is our home theater system.
I've noticed in the last 3 months, that my 2 year old Samsung plasma is showing red and green "flecks" that "rain" all over the screen for the first 30 minutes after it turns on. They fade after about 30 minutes and all is well. What can I do about this? Thanks.
I have this problem too. I have had a technician over to service it twice already and I picked up on a few things he did to fix it. Here is what I learned. the raining pixels has to do with the timing in the circuit boards. Basically telling them when to turn on and off. I would only recomend this solution if you are technically inclined. Remove the back from your tv on the left upper quadrant you should see a small gray dial with marks that a Philips screw driver would fit it. There are three or four of these on the boards scatter across the tv. Each on corresponds to the colors firing in sequence. Take your Philips and turn it to either extream. You should see a your screen go crazy with whatever color corresponds to the dial. Then ever so slowly turn the dial undtil you don't see any more flickering. Do that with each dial and you should be able to get rid of most of the flickering. on the right side of the there is a panel underneath the support bar with orange adjuster. I don't know what they do but they also help reduce the flickering. A word of caution. If you can use something non metallic to adjust these dials. There is a small metal lip to keep the dial from turning too far. If your screw driver touches it. It will fry the dial and your screen will blink red/yellow or blue. and you will have to buy a new board. Luckily they are only about 30 bucks, but I learned the hard way.

I have been having the exact same problem. TV on for 30 min with terrible static, then all of a sudden it is perfect again. I've also inherited a bit of a humming noise from the tv as well. It was suggested to me in this forum to have a tech come and adjust the v_scan and v_set settings down a few mhZ. No idea what this means, but I assume it's a power setting and the tech will be able to take care of this. I will post my results when i have the tech in.

Try putting a fan on the back of the tv to see if it is getting better. If it does then you probally have a board that is overheating. If that is the case then CAREFULLY !!! remove the back and place where you can turn on and safely access the open back NO TOUCHING STUFF !!! Mabey lay it face down on a glass table or lay it on a table with 25% hanging over the edge to see the screen. Then take a COLD blow dryer and blow it on the boards to find out which one makes it get better. If one does then it will probally be your problem board. Make extremely sure that is the one before removing it by blowing from all angles on the boards around it without air hitting the suposed problem board. Then try a little hot air to see if that starts the problem on that board so you can be sure. Of course check the surrounding and offending board several times to be sure before removing.

from the model number you have a 42" set,,the v_set and v_scan voltages need to be set 15vdc lower..this should take care of it,,if not then the plasma panel is bad
