SOURCE: Tv shuts itself off
Look for the computer processor inside the TV. It needs to be cleaned. A can of compressed air will work. The processor is overheating and causing the tv to shut off. Look for the small fan that is supposed to keep the processor cool then remove the dust.

Manual says you need to replace the lamp:
When do I need to replace it?
• It should be replaced when the screen becomes darker, less clear or when all three LEDs on the front (STAND BY/TEMP, LAMP, and
TIMER) are flashing

Had similar problem. Thought it was the lamp. Examined old lamp but it appeared to be good. Ordered a new one anyway. Changed the lamp but the TV screen would not come on. It would make the usual noise as it was going to come on normally but it would cycle 3 times & then turn off. The LED lights in the front panel would indicate a defective lamp. Then read about the ballast. Changed the ballast & still same problem. Tried starting the TV without the lamp installed & noticed that the color wheel did not spin. Removed old color wheel & discovered it was broken. This appears to be the cause of all of my problems. I wish I new earlier of the test-turn on the TV without the lamp being installed & check to see if the color wheel is spinning. Would have save money on the lamp & ballast.

SOURCE: TV wont turn on
a bad power supply is most likely cause of this. Other possible cause is bad main circuit board.
