17" monitor does not display, and pops inside.

I took the cover off and located where the ticking is coming from. It is some kind of copper wired wrapped square thing (With yellow plastic on it) about 1 1/2" x 1 1/2" in size. It is not a resistor. Maybe Voltage regulator?

Where to get a new one to replace it?

Any ideas?
 
Voltage Regulators are not wire wrapped.

More than likely a choke or relay.
Keep in mind if it is a relay, there probably is other issues.

Is it arcing? What Make/Model is the monitor?
Chasis number would also be helpful.

I do not see an arc at all. But it is wrapped in yellow plastic of some sort. The clicking does not sound like an arc either, just clicking.....


The Make of it is EMC and Model is 772. The product code is SA-770


As far as Chassis number, I am not sure where to look for that.


Thanks for the help!

 
This sounds like what happened with my bigscreen tv. But I could see arcing, and smell ozone.

Apparently what happens is that the energy required to charge the gas in the crt is shunted before it gets to where its supposed to go. There's energy in the order of kilovolts and it can kill you should it discharge through your body, so be careful when poking around inside there.

I assume your monitor is just like my tv: there is a wire going from the crt to some box near where the power enters the monitor. What I did was to coat this box with a thick coating of that orange gasket maker stuff for cars. This stopped the clicking and the power went to the picture tube like it was supposed to. This repair has lasted for 18 months now. I guess the coating wears out after awhile.

edit>> disclaimer: should you kill or injure yourself by doing this, I hereby absolve myself of any liability 😉 I think there's a way to discharge what I think is a capacitor, but I'm not sure how.
 
i donno...but by ur description...it's an inductor......it does the opposite of what a capacitor does....just think a mathematically inverted version of a capacitor......u can go the hardcore method, go measure the inductance, and go buy it from an electronics store.....i'm guessing the ticking is because the coating wore off and the high voltage is making it jump elsewhere ..but if that already happened, your moniter's bust...because a jump of electrons going to another area of the whole circuit will give unwanted feedback to that part of the circuit, and it easily could have burnt out a capacitor or transister (two components easily prone to damage from overload) somewhere...

warranty i guess?

From what I can tell, it only came with a 1 year warranty, which expired about a month before it started messing up. I have had it unplugged for a good month now.

I took out the suspect part a couple weeks ago and took it to Radio Shack and they didn't have anything I could use to replace it, and now I am guessing that one of my kids found the part and did something with it 🙁 I do not even have the suspect part anymore... I might just through this out to the curb and be done with it.



 
You mean a Proview EMC 772, correct?

The ticking (rapid cycling) means there is a short or overload,
probably in the 55v supply.

If you know how to test various components, I could suggest
what you should look for.

I have no idea how to test things like that.... I know what a capacitor is but that is about it.


It is a Proview EMC 772 yes


I do not even have that thing that was ticking no more, so my first thing is to figure out what exactly it is and get it replaced 🙁

I do have one out of a 14" monitor but it is smaller as I said and its pins are in a different order 🙁


This thing is kinda heavy for it's size (about 1 1/2" X 1 1/2" and black case on top and bottom and yellow wrapping I am guessing is covering copper wire or something along those lines... I have no Idea though....
