Re: plasma with vertical lines
i did download the panel manual a shorter version than the model manual, even the model service manual doesn't cover any info on service pattern access mode for my model or panel version. my panel is PDP42x2a and the model is DU-42PX12X.Leave a comment:

Re: plasma with vertical lines
