A lcd tv(32") was brought in for repair at my workshop.The maker is
'acoustic solution',I don't know they are into lcd because I had
repair their dvd products very well.The fault is that when it is power
on,a black bar is at middle of the screen and it extends to the bottom
of it.On opening the cover,i saw two capacitors (15uf 450v)close to
the inverting transformers,one of it is bulged while the other looks
fine.Ranging my digital multimeter to esr i detect both capacitors are
faulty so i changed them with same value.when the lcd was powered the
fault was gone.
