Turnip:
Hi, Folks.   
   
    Have one of these - perhaps LG - where screen shows narrow vertical coloured stripes which change with picture content. This is my first Plasma job, so a few thoughts of where to look would be most useful.

   Thanks - Turnip

tv tony:
disconnect lower y drive pc, if top half then ok replace lower drive, be warned though its best to replace y sus as well, what model is it?

Turnip:
Thanks Tony,

  Your concise advice confused me somewhat. Being new to Plasma, I still don't know what's missing. As a 'Component level - picture valve'  sort'a chap (haven't any spare panels yet, and am far too mean to buy any) a brief synopsis of the situation - as with your rather handy one on Vestel LCD power panels, that got me to the root - might be the business.

  In hope of a spare moment  - Chris.

tv tony:
sorry for slow response, on the left hand side(from the rear) there are two narrow panels which interface with the y-sus pcb, the large one, and the pdp (screen)
there is a small cable which supplies 5v and data to the lower pcb, take that off at one end and disconnect the same board (lower) from the large board, if you now get the top half of the picture your lower y drive is goosed, dont touch the ribbon side that connects to the screen at this stage, and get back to me

btw what model is it

tv tony:
sorry, got model
