Has this TV ever been properly restored/recapped by someone in the know about Predictas ? There are quite a number of things that could go pop and render your TV inoperative in the way you describe . The tube's heaters lighting means the set is getting power and that at least part of the circuits are still functional . With neither picture nor sound a B+ voltage issue is one highly likely possibility especially if any old capacitors are still lurking about in there . If it has been properly restored maybe your just seeing the "infant mortality" of the many new components ? It it hasn't been properly restored , even when this most latest issue is fixed , you'll likely begin frying expensive parts if you keep running it ...

The TV was restored by it's previous owner, who is a collector that seems to know a lot about those sets. But the truth is, that he admitted to me that he didn't replaced all of the capacitors of this TV. I remember he saying something like it was a lot of work. So that might be the origin of the problem, right?

Yes, it is a lot of work to properly replace all of the capacitors in Predictas, but if that is not done, the set may not be very reliable. These articles show what I did to restore a couple of different models (one 21-inch, the other 17-inch).

Not knowing exactly what was done, it's hard to say whether the previous owner did a thorough job. Predictas were known for being somewhat unreliable even when fairly new.

HI All;
I would say to watch Bob's Videos on when He restored His Predicta's, and then follow or check the one you have and see If what He did has been done to yours.. And also look at Phil's articles mentioned above and doing the samething.. Otherwise it might be easier for you to replace everything, rather than waiting for it to "pop" and then replacing it..
THANK YOU Marty

TV is working again. The tech detected that it was a small diode that had short-circuited. Probably it was fault of the outlet I was plugging the TV in, it doesn't seem to hold the plug very firmly.

Very good,thanx for the good news :)
