Is it a new set? Has it lighted before? Return it DOA to the seller. Change batteries in your remote, maybe it will reset? If it won't switch on manually, its the TVs fault.

You need to replace the Color Wheel.

Sorry... this is not a solution, but I wanted to speak directly to you and didn't know how else to communicate with you!! OMG!! My t.v. does the exact same thing!! The power issue and the sound going out after it has been on for a while!! Have you called Samsung yet? I hear they have horrible customer service. Maybe if we get enough people with the same problem we can get something done about it!!

LED flashing is unable to charge

remove the lamp and visually check if inside looks broken.if visually do not see any thing wrong,check if you have 300 volts dc supply on the ballast which starts the lamp.if you do then the ballast may be defective.if you do not then the power supply should be checked.
the lamp should always be tried first especially if is older than two years.
note - be aware about the switch at the door lamp.the door should be closed,otherwise tv will not work.if you remove the back cover,make sure to bypass the switch temporarely so you could work on the set.
