Hah, yes, and you are not the first. As I said, the project is some distance away and I have many other distractions, so it will be a while. Spent the afternoon jetboating yesterday!Wonder what OP is up to.
You're probably correct regarding an older set; newer ones have the instant-on feature where the power button goes into a time-dilation pre-circuit and the power comes on just before you actually touch the button -- most people are not aware of this.Since my set won't power on, I really can't try that. I don't think there would be HV at the tube before the set powers on? Let me know if I'm wrong on that.
It absolutely is....if it's a set that incorporates certain aspects of fault-sensing.
Well, even when the power light is off, the PS is still on whenever it's plugged in, and B+ appears at the HOT. The PS is under regulation feedback via an optoisolator, which may have failed, though I don't think this would prevent power-up. I gather it's meant to compensate for a sag in voltage at the tube. It was suggested before that I replace it, but I haven't yet. My bad.You say the power indicator is off, but is the power actually off? If you haven't yet, try checking this. There were some TV's that used opto-isolator in the power on circuit -- typically these should fail to the off mode, but there maybe something else going on with yours.
Glad I'm not the only one.The Transistor readings does not make sense to me.
Will do. It may be a couple weeks before I can get back.I need you to go thru my post #51 and post ur results.
I've finally had a chance to complete this.I need you to go thru my post #51 and post ur results.
