The topic says it all. okay, heres the scoop. i got a c64 off of ebay, and it didnt have an RF switch or a Power Supply. so, i used an existing RF switch, and i just got a power supply in the mail yesterday anyway, the light turns on, and when i turn it on, there is no proof of it being on, on the TV. THE DAMN SCREEN DOESNT SHOW UP!!!!! anyway, is it the RF switch, or is it just the system? cuz its not the power supply. so all in all, the red light on the system turns on, the screen gets a little fuzzier when i turn it on, but doesnt show up, and one more thing. i also have a disc drive hooked up. i doubt thats the problem.
