Re: the picture is unclear with a large red spot in the...
In most cases this requires the replacement of the light engine in these sets. The heat build up in the set slowly damages the LCD panels wich then causes the red spot. The replacement light engines have changed the cooling and filtering to the set. It should last much longer once its replaced. You need to have a technician verify first that this is not just an adjustment. I would say 95% of the time it will be the light engine.

Usually means inverter or power board is bad! Check power board for voltages. Voltages are usually printed on the header port. if Inverter is bad panel would need replacing. If TV is less than or equal to 12 months contact Samsung for warranty repair.
First check its main power supply regualtor board's output voltages. If any of these multiple voltages become low than normal, this type of fault can occur. If you are not familiar with
electronics, do not attempt to repair.
Whether you suffer fatal electric
shock. Instead, contact
any experienced service technician, or the nearest service center.
This tv is a DLP projection tv right?Magic focus button push don't solved the focus picture problems,have colors shadows or 3D pictures problems?The tv have a problems known as a convergence problems,it dead.The tv convergence board.Must have it 2 STK convergence ICS and some or all it resistors to be replaced to solved the tv picture convergence problems.The shop,will cost u $300-$350 for parts and labors.
With most flat panel TVs, the TV turn itself OFF when it has a fail electronic part and the red light starts flashing. They call this "Protection Mode". The flashing red light should be a error trouble code.
But, it's weird that everything is working and the red light is flashing. Since you just recently bought the TV, I would get it check out while it's still under warranty. Better safe, than sorry.
The faint light indicates that there is not enough power being provided to the other circuitry as well the humming sound is a good indication that the power supply needs ot be replaced or repair. If your TV is less then a year old, still under manufacturers warranty.
Let me know if you require further assistance.
I had red and green spots, and I called the service department at the furniture store where we purchased our 42" TV. They said it needed to be updated, and they picked it up, fixed it, and delivered it back to the house for about $25.00. We had a warranty, so it only cost for coming to the house twice... No more spots!
