Question about Samsung HLP4663W 46" Rear Projection HDTV

1 Answer

Loud Buzzing Sound - Rear of TV

The unit is working perfectly and there are no lights flashing in the front of the unit. Picture quality is also excellent. However, there is a loud humming or buzzing sound coming from the back of the unit. Sounds like the fan. When the TV is truned off, the sound winds down.

HITACHI MODEL # 53UDX10B has a flashing red light and a buzzing sound

If it was transported likely the set was damaged--one of the three picture tubes used could have been damaged--the flashing light is the set trying to come on and the buzzing is related to whatever is bad.

It needs to be opened and inspected.
