Morning all,
re the LG 42v6 and similar, can anyone explain (simply) why, when you have the fault of a screen of vertical coloured lines, disconnecting the bottom drive board produces a picture from the top board.
I know it's a common fault, but It would be nice to know what is actually happening.

Hi Daz,

Are you quite cool - Local freindly folks are about to go North helpfully with some rather old Turkey bits - Chris  (holding nosewise) but Quuq folks (esp Brian - a veggie) am the biz.

markc:
I'll take that as 2 'Don't knows'  then!
Any more offers?
:dubbio:

Hi Mark,

You will have to excuse my friends Chris and Daz, they haven't been the same since they lost their 'special'
helmets that stop them licking the windows on the bus.

I don't know for sure but I suspect that when the lower buffer board fails, the faulty buffer board is corrupting or distorting the Drive waveform, hence when you disconnect the buffer board, you are then removing the corrupting influence and the drive waveform is then 'clean' and you then get a 'clear' picture at the top of the screen.

If any Techno wizards no any different i'm sure they will chip in

Brian
