You can check with Samsung to see but a word of caution--I have seen people do firmware/software up grades and suddenly have new problems.

red noise on the screen can be either the main board or even the power supply board--the latter may be tested for voltage but the main would have to be replaced to know if it is the problem or not.

If you have not tried it: unplug the set and if using a cable or sat box unplug that as well---wait for a while and plug both back to see if a reboot of either cures the problem or not.

fast way to know is c a l l Samsung with the model number and ask or if need the owner manual Google the model number with "manual"

The only way to repair this problem is to replace the screen/display unfortunately the price of the screen is so expensive that repair is not financially feasible. I am television technician for a 37 years now still active sorry for the bad news if you list the television on craigslist list are eBay you may get offers and also check with shop Jimmy on Internet they may buy your plasma Ron

please follow this step: you have customized the picture and menu settings on your Samsung TV only to find that they keep reverting back to their default positions, this is because your unit is in what is referred to as "Shop Mode." This is the demonstration mode used by electronic retailers to show potential buyers all the features a Samsung television supports. Press the "Info" button on your remote control, and if under the "Picture Mode" heading it reads "Shop Mode," hold down the "Menu" button on the TV itself until the screen reads "Dynamic Mode." This has changed the picture mode to one of the pre-set positions. You may now change any settings you'd like.God bless you

It will be cheaper for you to buy a new TV set. Replacement screen most likely will cost more than the price of a new set

Likely the "main" board that processes all digital information in and out of the set---Not likely to get fixed in the home or be a do it yourself repair.You might want to call Samsung with the model number to see if this is a known issue in this model or not.

Most likely the power supply board went--here is some general information and suggestions:I see so many here with no sound/nopicture issues:ISSUES: 1. IF sound main fuse/s are good.2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.4. Be safe and if you do not know what you are doing don't open the set.Answers to issues:1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.3. Trouble shooting consists of the above and then at some point you have tobuy and try a board to see if it fixes it or not.4. Safety first--no TV set is worth getting injured or even killed over.Take a look at the power supply board inside the set and see if any caps are puffed up like these bad ones are.

Either a bad board or a bad Plasma Display Panel (entire front screen unit which if bad is fatal).
