Question about RCA P52930BL 52" Rear Projection Television
You have already diagnosed the tuner as the problem,the first thing to check is the conections at the tuner specially the ground conections,the shell of the tuner is the ground and it conects to the chassis by being solder to it,if all conections check ok look for overheated areas.After that is taken care you still have the possibility of having a bad tuner.If you are familiar with tv service this information will help but if you are not too familiar be safe and call for assistance from a servicer.
