I have a WGM2574-U4GR37B chassis in a Sammy Sports Shooting. The picture was compressed and getting worse. I could see C729 had expanded & replaced this. Now the picture is worse. What other caps do I need to change? Also, I have a WGM2725-U4GS27J chassis, it looks the same, but has just wires and a plug connected in place of Q710. What is the difference in this chassis? Can I simply replace Q710 from my bad board and use this one

?
