Question about Samsung PS50A466 50 in. Plasma HDTV-Ready
Thanks for using FixYa. From what you have described it seems to be an issue with Y board however, Z and the logic board should also be checked. These boards are located on the right side of the unit and to check them you'll have to open the back of the unit. Once you have opened the back also check for any blown/bulged capacitors. All this is only recommended if you have electrical expertise & know how to solder/re-solder components as these units contain high voltages even when in off position. Please accept the solution if the issue is resolved or post a comment for further assistance.

Sounds like a failed or at least failing power supply / power board
inside the TV.
Unfortunately this is a very difficult repair, and unless you are an
electrician I would not recommend attempting it. You will need to
contact a local TV repair person in your area. This is actually the
most common problem with this type of TV, I see it every day, it just
happens - sometimes with new TVs and sometimes it takes many years for
it to happen.
If you think it may still be under warranty please contact the manufacturer to file an RMA. If you happened to purchase the TV with a major credit card (not a debit card) there is a good chance it may still be under the free extended warranty most credit cards place on electronics. Please contact your credit card company to inquire if they do this, and they will be able to file the claim and get you a refund for the TV.
If you want to attempt the repair yourself please let me know and I will get you the part number and a place you can purchase it from for what you need.
So sorry that I don't have better news but it is definitely a power issue internally.
