Hi Vincent,

Have you tried any of the other inputs? I assume you are just using the HDMI inputs, it is very unusual to get multiple faults on one of these sets so I would try the scarts and the freeview side and see if you get a picture. You need to refit the SD board and then disconnect the ribbons that connect to the screen to make sure you dont have a screen fault. Also i would examine the screen with a magnifying glass to see if you have a blown "pixel".

Regards
Brian

Hello,

thanks for the answer ;

so i try with AV1 input and AV2...not the other one ...i every time have sound but no picture.

Connect the SD board but not the ribbon for the screen...i try and i have the same error
i'm sur that the SD card is dead but i may be also the screen...because they still stay
white without any error...but some plasma need the two card to working properly....

When you say dead pixel, i mean that only one dead pixel explain that the screen is dead ?

i try another panasonic repair center to found my information or if somebody could continue
to help i would greatly appreciate  :ciao:

Regards,
Vincent

Hi Vincent,

If you still get the error code then you are right that the SD board has failed, so you will have to fit a new Sd board, the reason I asked you to check for a blown pixel is that this can damage your new Sd board. I dont know why you dont have a picture unless you have another fault!

okay,

So i'm sure that the SD is dead, but when you say a dead pixel, it mean that a black pixel,
green, red, blue ? or maybe white...i supposed that dead mean black on plasma...

for the white screen i contact a lot of panasonic reparator and nobody are sure that
this blanck screen is normal, someone say yes i could be normal and someother say
it could not be normal..so i still at the same point  :huh1:

it hesitate to buy this news card....i let me one week to found solution...or answer to
the blanck screen problem (or not problem)

best regards,
Vincent
