The problem is the power supply components over heating. The power supply is on the back side right hand. supply extra cooling via a fan and it will stop shutting down. This is just a cheap and simple fix that wil tie you over for a while. cheers mates.

Hello Chac c,
The reason that you are getting a 'red light' is because your lamp is burned out. There is a panel on the back of the TV that gives you access to this lamp. You can remove it and check the part# to be sure then replace it. I did a quick search for you just based on the model# which you provided. You can see it here - http://www.nextag.com/serv/main/buyer/OutPDir.jsp?search=samsung+lamp&gg_site=&gg_aid=1295966762
Hope this helps :)

SOURCE: can't turn on
When you turn the MAIN off you are killing all power to the set---Some advice---If you Google the model number of this set with the word problem after it you should find what I have seen a lot in these sets: they develop bad solder connections on the power supply printed circuit board---usually the board is about 18 inches tall and 12 inches wide--A number of sites online offer to have you ship them the board and they will resolder it for you.
I have repaired about 12 of these with this problem in the last 2 years---The board has to be removed(there are quite a few plugs that need to be labeled and removed and lots of screws that secure the board in place.)
Maybe not a job for a do it yourself person but the soldering (if it is your problem) will take about 45 minutes(including removal and installing board back).
Like most modern sets this set uses lead free solder and it is soldered(the boards) in a wave or one step process---over time from heat and expansion some connections may crack or even break loose----I would look at the POWER SUPPLY board(follow the power cord as it goes right to it)
