I was given this Panasonic Plasma TV in non working from a local home theater install company. The unit power off / on with no problem. But the picture is coming on with distortion. I have downloaded the service manual and read it and found nothing related to my problem.
What I have done so far was:
I made voltage measurement all in spec.
Next I started with the buffer board. There is 5 of 74VHCT541AT on each board. swap the 5 74VHCT541AT on one side of board to another and the pattern on the screen swap placed. I couldn't see the menu before the chip swap.So I order from Mouse 10 of these 74VHCT541AT.
I haven't repair any plasma before but I have work on many LCD monitors and LCD TV. any advise will be helpful
Thanks
