The answers above are correct. It's either the lamp or the color wheel. Testing the lamp is pretty straight forward. Use an Ohm meter to see if the it's filament has continuity. It's unlikely that a good color wheel would fail immediately after changing the lamp. Look to see if some wiring is out of place and rubbing the wheel causing the noise you described. A jammed but otherwise good color wheel would cause the TV to shut down and display an error code.
Are the red and green lights blinking at the same rate or not? If the green light is blinking every 3 seconds and the red light is blinking every 1/2 second, the lamp door is not properly secured. If both lights are blinking at 1 second intervals, try replacing the lamp. If a new lamp doesn't solve the problem, the TV needs service.
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.
Could be an LCD drive board or a ballast. This is what to expect from free advice..... A guess. If you pay good money for a set why not get a factory tech. who knows what to do to solve your problem. I don't do LG warranty right now, but I did when your set was new. Here is a free gift. Start by having someone test the lamp tempurature sensor. It is a very thin black wire with a small fuse-like thermistor with heatshrink tubing around it. It is mounted on or around the lamp and can be purchased at any major consumer electrinics distributer. Good luck, Russmann.
same problem as others 3 blinking green lights then orangey colors then 3 red blinking lights afterwards shuts down fan runs for about 2 mins solution check your door cover for warpage or deformed just a bit under set screw there is a push in switch try and push it in with q tip while holding turn on tv if it works then that door is deformed and defective change it
thanks for solving my issue tv works again very helpfull thanks
