|
got a MZ42PZ44 lg 42" plasma,
it origanally had 2 black vertical lines on picture.
picture below
managed to repair the black lines there was a dry joints on 2 10Ω resitors on diffent blocks in front of COF IC the black bars have now now gone but instead theres now faint white lines on picture,
not sure if its screen burn or image retention?
heres 2 pictures of the white lines which now exsist, and only really visiable when theres a white background.
tv on white wash
also on further investigation i noticed on the ysus board one of the big samwha elec 250wv 680uf capacitors is buldging.
cap has not been replaced yet,
just curious these big caps on on the ysus, if any of them are leaky or buldging would it cause the faint white vertial lines shown on pictures above im getting? as dident think faulty high voltage caps would cause 2 white vertial lines in same place the origanal fault was.
any help would be very appretiated.
thanks |
