Question about Hitachi 42PMA400 42 in. Plasma Television

Intermittent noise coming from back of screen

Sounds like a fan hitting something but it stops when the image on the screen is dark. It has always had a slight buzz on white images but this is much louder.

    Where can I get a spare power board or is it serviceable ? I had the same problem with mine but then it just gave up the ghost and I got no Red or Green Power light, totally dead. Hitachi agent here said they can't get the power supply as it is a UK model.

could be your hard drive thats dead. You might want to go buy a new one. Depending on if you have a warranty on it you should pop open the case and try turning it on if its coming from the hard drive your hard drive died. It also could be a fan hitting something slowing the cooling process and overheat your processor.

I have a Sunsung RS21JLSG, and it's not chilling the food like it should. It's making terrible noise, sounds like a generator. Anyone know the problem?


Fan blade is hitting something probably, could be ice buildup in the freezer compartment. Open the freezer door and see if thats where your noise is coming from. If it is coming from the back of the refrigerator at the bottom could be something was drawn into the fan causing you noise.

LG Fridge making intermittent sound - like something hitting fan


GAIN ACCESS TO THE FAN IN THE FREEZER(EASIER SAID THAN DONE) AND INSPECT THE FAN BLADE AND FAN SHROUD. HAVE REFRIGERATOR TURNED OFF AND MANUALLY ADVANCE FAN BLADE. WATCH FOR SLIGHT CONTACT BETWEEN THE FAN BLADE AND OTHER OBJECTS NEAR IT-ELECTRICAL WIRING, FAN SHROUD, ICE CYCLE,ETC. ADJUST FAN BLADE OR OBJECT TO INCREASE CLEARANCE.
