I have sound but no picture!
I recently acquired a PS60690 and the screen no longer works. I turn it on and there is sound, but no picture at all. I'm trying to figure out if it's the picture tubes or something else.

Usually a loss of picture problem on this set is caused by parts on the circuit board failing. Most often a repairman will find the problem around regulator in power supply or around main output transistor in horizontal circuit. Either way, solder work and test equip. are required.
