Question about Mitsubishi TS-5057 50 in. Rear Projection Television
There are no bulbs in rear projection TV's, there are only 3 CRT tubes which project a picture on the screen. The bulb your referring too is that from a DLP projection TV which is a very different technology than rear projection. Since you have a rear projection TV that has audio but no image this means there's a problem with the TV's HV deflection. Here's a list below of the possible faults:
Bad fly-back transformer Bad HV splitter Bad Convergence IC's Bad Horz/Vert output transistors Cold solder joins along convergence area
Its best to get a professional to resolve this for you as rear projection TV's hold a deadly charge even when unplugged. If you don't discharge the flyback / tubes, the charge can kill you in less than 1 second.
