|
|
I turned it on a few minutes ago to warm it up, and was walking by the room, and smelled that 'electronic' smell. I'm pretty sure that's ozone that you smell. Well, it was pretty potent. We watched a movie last night, and it did fine. In fact, I've watched about 3~4 movies a week on it and it's fine. It was still working when I turned it off. No evidence of anything going out. Nothing was warm yet; it was all cool to the touch. For the record, it's never put out this smell before, and I've gone through two power supplies (many moons ago, before Curt rebuilt one for me).
I wanted to check with you guys first before I keep using it, just in case it's just a cheap part to replace, instead of running it until it pops and then I'm out a projector.
Oh, and no problems in over 2 years. It's an Ampro, maybe I'm just overdue? 
So guys, what part of the projector fills the house with ozone smell in the first 5 minutes of it running without blowing something up or overheating?

Open the top cover and flip up (down) the reggie/convergence boards. Ozone will show as blue arcing. Keep the fingers away, as it's 34,000 volts. See where the arcing is coming from. I'm guessing one of the HV leads where it plugs into the HVPS.

It's ceiling mounted. If I drop the convergence board tray, I should see it when I turn it on? You have the big tray and the small tray, I'll just drop both.
What causes this? Is this a board or a HVPS problem? What are my probably expenses? I'm not sure how many parts are still floating around for that old bird...

Umm, I have all of the parts..
YEs, do that, and you should see the blue glow. Once you confirm that the blue glow is coming from the HVPS output, wait about 5 minutes after unplugging the set, and unplug the HV leads one at a time from the HVPS, and once you disconnect the lead that's leaking, the glow will go away and the smell will go away as well.
$25.00 will get you a new HV lead with shipping, the installation isn't hard, but is time consuming:

You need to pull the tube with the bad HV lead... It comes out the front of the set.

What makes a lead 'leak'? That's something I've never thought of or seen before...Bad insulation? Exposed copper?

Don't pay any attention to this. He hates AmPro products. He had one once that had the "blue arcing" problem. He tried to piss on it to make it go away. Now the poor bastard doesn't even like girls anymore

errr...I looked...I see no arcing, but the smell is there the second the tubes charge...I'm not seeing ANYTHING...projector image looks fine...I'm all ears...
And I know about Pete and his love of the mighty Ampro. If he sees Ampro in the thread, he jumps in just to make fun. I think he has a secret crush.

Then go by the smell. Disconnect each HV lead and see if it goes away at some point in time.

I also dislike the University of Alabama (aka Gump's home).
Ampro were manufactured according to government specs and quality control.

Being a former USDA employee, I can say with certainty that the Ampro's standards and quality are much higher.
I hate Bama too. Ole Miss fan here.

Would using hte RCUT controls help, or would you literally have to disconnect it?

Ok, where to I unplug these? At the black box inbetween the red and green tubes? Isn't leaving that lead hanging out like that a wee bit dangerous? I don't have a clue what I'm supposed to be doing. 
Does this leaking ozone thing hurt the projector? Is this a busted silicon seal on the tube?
