model # hd50lpw166yx7, TV is 3 years old. Yes the 5 blinking lights of DOOM are back, after I replaced the lamp, then took to TV repair place, they told me it was a bad color wheel, called RCA, they sent me a new one, put it in, pluged it in, once again 5 blinking lights! What should I attempt to do next, the ballast? I'm already into it, lamp $140, diagnostic $50, and now a color wheel $145!
