SAMSUNG HLT5675 BULB LIGHT BLINKS

You might need a new housing! Sometimes, the housing can be damaged with a new bulb and it can caused the TV to want to shut off.

3 blinks indicates lamp door is not on or has not been reinstalled properly. This also could mean the lamp door switch has failed itself. Try removing the lamp door and putting back on, if that doesnt correct the problem then I recommend having the switch replaced.

Hi,
If red light blinks 3 times when tv refuse to power up then check lamp cover that was removed to replace lamp, make sure lamp cover is fixed in its position securely and screw is tight.
Let me know how many times red light is blinking after three second long pause IF it is not blinking 3 times.
Thanks.

Does these LED indicator lights that blinks?It is one of the LED light said lamp or bulb?The tv been used alots,and it at lest 2 years.U have not change the tv lamp or bulb to this tv?Change it,life of the lamp it over.

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.

Same thing happened to me (By jschmidbauer on Jan 14, 2010). How did you fix it????

I have the same issue, we've had to change our bulb three times in less than two years. now we have 61" expensive paper weight. Our current bulb is less than 6 months old. The TV is only 2 years old and like i said this is our third bulb.

the blue light blinks 4 times. you get sound. then a few minutes the the picture returns... then it goes out, and the cycle goes on.

A solution to this would be greatly appreciated.

Its problem of bulb that got weak in result and causing TV shut down.
Replace bulb in TV and I would recommend to buy Sony original bulb for TV safety.

There is an additional problem,

if the bulb had been replaced by a technician, call them back and ask for additional support, since they did not fix the problem.

beings the connectors were different on the new bulb the spark gap maybe different also if it is the lamp wont work in that unit
