Re: Samsung PS50a410 - no picture
Yes the screen is back lite you can see it come on when you start up but no picture has sound
Yes when you unplug the three top ribbons you get a black top screen not the lite screen and visa versa with the bottom three cables to the y sus board to the left hand side of the tv looking from the rear
Normally if you do this to a buffer board you get picture when you unplug the faulty one
all the voltages check out so Im at a lose

Samsung PS50a410 - no picture
No Picture - just back lite
Have check PS voltages etc all are good
the logic board is blink ok
If you pull the top three ribbons on the Y sus you get the usual black half screen and the same goes with the bottom no dancing colour box etc like if the buffer boards were gone.
Thought it may be the eprom needs to be reset ---- just a thought??
If so how should this be done
Other than that any suggestions??
have another with the logic board not lighting... -
Re: Lg Plasma sound but no picture
Buffer boards on the y bus
Take the screws out. Take the top board out and
turn tv on if you get a black screen turn tv off then replace
and do the same to the bottom buffer board turn on
You should see a Coloured block dancing on the screen. Order the buffer board that gives you that effect

Does anyone have the training manual for the pdp series 4? or a SM for the PS50a410?
I think it may be the logic board
