We have a samsung L40a630 tv and it's not turning on. The red light blinks 3-5 times but then it shuts down, and keeps cycling through the same process. We have taken the back cover off and checked the capacitors but none of them are bulged. Can you help us?

Hello, count the blinking light pattern. It may blink 2 to 9 times, pause and repeat the pattern again. Does it ever light the screen when it's cycling on and off? Let me know....tks
The projection lamp has not been replaced like 1 1/2 or 2 years and tv on and used like 4 or 5 hours a day on this tv?yes,than the projection lamp life is over.Require a new projection lamp.
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.
If the TV will not turn on and the red light blinks on the front of the set, it means that the microprocessor has detected a problem in the set and shut the set down. It then blinks the red light a certain number of times, and the number of blinks is the code for why the set has shut off. How many times does the red light blink before repeating?
