Hi Snopy44,

Culled a couple of Quuq bits from another 50 inch panasonic -

1.  Central black bar top to screen middle.
Im afraid you probably have a faulty screen, you could try cleaning the ribbons but I doubt that will be your problem, and there are usually some little SMD resistors that can fail on the C1 or C2 boards(usually about 18 ohms) but if one of those have failed then im afraid its usually caused by a defective screen.

you need to take the back of the tv and and where the black line is on the screen you will see a rippon
you need to unplug the rippon you will see 2 resistors resoilder them and the black line will have gone


All the best - Chris.

PS Had the trouble on a LG and it was dry jointed resistors on those ribbons

hi thanks for the reply i have just striped down a th 42pe50b dont know if these are sim but on this model there is no resistors on the ribbons on this model so if they are the same would it be better just to change the 2 boards any help is apreciated as iam just learning and as my old mum would say you never get anywere if you dont ask :c017:
