Hi, You may have two problems with your TV. This TV has a history of a color wheel issue, was making grinding noise? Have you ever changed the lamp? It may be a bad color wheel and the lamp, you may want to do a visual inspection. It is easy to replace the lamp but more likely the color wheel is the problem. The part# for the color wheel is 212184, the part# for the lamp is 260962
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.
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
Unfortunately, what you're describing is a repairissue. You won't be able to address the problem with troubleshooting.There is a part inside the TV that needs to be replaced. If the TV is a rear projection AND all you need is the lamp, you could probably fix that yourself. However, if it's an LCD or plasma, I would advise you not to try the repair yourself because it's more complicated than replacing a bulb. Using Google to diagnose the problem carries some risk because you run the risk of wasting money on part of a repair. For example, if you learn that you need to replace the lamp assuming its a rear projection, you fix the lamp and the TV still doesn't work, you'll be faced with spending more money on repairs than you want to. A new 42" LCD can be purchased on walmart.com for $598.00. So, you definitely don't want to spend too much more than $200 for repairs. If you do have a rear projection, the replacement bulb will cost about $200. If you'reunder warranty, this will cost you nothing.

I looked up the manual online - after you replace the bulb, you need to reset the bulb life timer. Using the TV remote push the menu button, SETUP menu, select the lamp reminder option to reset the hours to zero. That might help the status indicators.
do a self test diagnosis by pressing the menu and device/input buttons on front panel for 5 sec and you will see a seq. of blinks followed by a short pause and then more blinks. count the first set and last to give you the error code.
