stu:
i have a samsung plasma ps50b430p2wxxh, sound but no picture.
va/vs volts fine from psu, set is running, suspect the ymain board faulty.
cant find fault on it, can anyone know any info on this model and any common issues please?

many thanks :sign0085:

Forget the T-Con, it's a plasma. Are the heatsinks on the Y-Main and Z-Sus boards getting warm? Is the LED on the Control board lit up? Have you tried generating test patterns using the Auto Gen on the Control Board?
