I bought a Panasonic TH-50PX75u off a good friend of mine, it was broken when I bought it, he turned it on and nothing but seven red blinking lights would show up. I figured it was an easy fix so I got the panasonic troubleshooter and found out that when I remove the SU board the top half of the TV works fine. When I put it back in, the entire system fails and blinks seven times. I hear a click every time I press power.
I replaced the SU board, same problem. I replaced the SC board, still nothing!!! I am stumped. Is it the P Board or where do I go from here? Anyone else who had this problem please help me out I am ripping my hair out for this TV. I hope this is an easy fix, the service manual was no help.
