Television and Home Theater

Since I move to my new house my Sony TV model KP-65WV600 start showing a ghost shadow right after my extend warranty was expired and I have been watching that TV with a ghost shadow almost a year and I desire to call a TV service company to fix it.

My sony TV has lost its picture. The sound works but no picture. The memory light is flashing 7 times. I was told that I needed to replace a part# 875967030. On line I found the part for $22.95. It gave an alternate part # IC-MC23001DB. The cost for installing this part was about $400.00 est. I can't afford this installation cost. Is there a way I can find out where this part is within th Tv set? I have a very good friend who builds computers that can install the part. Or any other info you can help me with. If not I will let the Salvation Army take the TV.
