Title: panasonic TH37PX70B
Post by: g*****s on March 06, 2012,04:31:01

Another one of these in,this one has a not quite solid green pixel line down very centre of the screen.Things seem to be pointing to D board replacement.Any advice would be great,as dont want to buy a D board then find its the panel.But its for a friend so trying to keep cost down.By the way was told drys on the D board can cause this but have given it a good seeing to and its still the same.Board number is TNPA4133.

Hi

can you post a picture?

if its a single line down the screen, then it is usually the PDP

Hi

I can see the pics ok, It is all most certainly a faulty screen, but you could try cleaning the corresponding ribbon from the C1/C2 boards

All the best

I have a problem with the same tv my problem is the screen only shows white and i seem to have found a faulty diode on the power board d411 however i can't find a replacement diode as unsure what it is its marked on the diode as T2D 68 with a line under the 8 anyone know a suitable replacement?

I may be missing something but that link just gives me a google search listing a load of data sheets with t2d 68 somewhere among the text however nothing showing what the diode i need is ?
