any LG plasma techs on here. bad picture on 50"
« on: July 02, 2013,09:25:20 »
hi guys.

i managed to get hold of a 50" LG plasma 50pm680t

set originally had a problem with just 2 thin black horizontal lines going all way across bottom of screen ( picture was perfect apart from this)

i put this down to a faulty lower buffer or the screen tab needs reseating.

however what happened is i forgot to clip the blck screen tab connector on buffer down on switch on silly me.
so im guessing its shorted the buffer and might of shorted the y-sus


now the symptoms i get are just black picture. however i removed bottom buffer completly and just left top buffer in and i get like a mal-discharge effect like in picture i attached. sometimes the picture is just colored dots appearing on screen.

so for sure the bottom buffer has shorted.as its just black with both buffers in tv.

my question is does this look like a blown y-sus or buffers or -y-sus and blown buffer?
