Question about Televison & Video
I have a LG TV LCD 47LF65 for about 2 months and i noticed that when i turn down the brightness from 85 below ( i use 75) it makes a strange noise. not to loud but anoiyng. can someone tell me what to do to solve this problem? or is it supose to do this noise?
thaks in advance
It should make a little noise, but if it is annoying then it is probably an issue - this is most likely the power being reduced to the inverters when the birightness is turned down. Could be a noisy coil on your power board or a capacitor may be going bad and changing value. I would look for any swollen capacitors (a bump on top, bursted or swollen sides) on the power board.
