When i turn on my tv i can hear the sounds but my whole screen is blue


do you see thin curved blue lines going from bottomto top of screen. If so its most likley a blue CRT drive board issue. If its a solid blue it could be a small signal board issue.

The Red,Blue,Green do not line up and keeps blowing fuse


you need to replace 3 items FL231, DL231, CL230 then resolder the vertical IC and flyback conections. You can get the three components under the RCA parts category at this link.

Good Day, citiofdreemz;

Rca big screen television 65 inches


the clicking is the relay clicking which is one of the first components when power is applied. Your set will need to be diagnosed by checking the stanby and start up circuitry. Unless you are skilled this is one chassis thats left to a skilled repair tech. They have alot of problems with the power supply and deflection circuits, flybacks and etc.
