Repair my Eon g2.. can it be successfully done?


Recommended Posts

I brought my Eon G2 into repair place ( typical $100 an hour for some of the keyboard billing ) and the guy is hemming and hawing about repairing it. I said, I will pay you whatever it takes.. still the attitude.

Question.. is a 10 year old speaker a problem to make like new ( not the outside cabinet obviously- just sonically ) ? Parts not available? The sum of the parts, would cost 3 times the value?

Whats up with this foot dragging ? Or is it a legitimate issue?

We talked about this in an earlier thread, remember? :)

 

The schematics are on the internet.

 

Aged Horse - on the Harmony Central forum told me the problem was a capacitor in the muting circuit.

 

I tried to call him on it thinking he was just blowin' smoke.

 

But #1, he designs amplifiers for a living. He knows his stuff.

 

#2. He was confident. He has seen these capacitors fail before.

 

#3. I read some time ago that there were electrolytic capacitors that someone copied from a reputable manufacturer to rip off the formula of the electrolyte and sell them cheaper. (No, this time it wasn't Behringer.) They got it wrong and all those capacitors that are in many consumer and government devices are failing, or have failed. True story.

 

Opening up the box isn't a problem. And if you have the schematic to give to the tech, he should be able to find an off-the-shelf capacitor to replace the bad one.

 

If this is NOT your problem, with the schematic he should be able to locate the problem. Most of the electronic parts are not sole sourced by JBL.

 

I think the guy is either lazy or...

 

OK, I think the guy is lazy.

 

If you cannot find the schematics (Google is your friend) let me know and I'll try to find you the link.

 

I swear, it's easy to get this information. If he doesn't want your business, isn't there somewhere else you can take it?

 

I know you are fond of the G2 speakers.

This is a common problem on a lot of modern power supplies - often they just undersize them or have too low of a temperature rating for real world applications. My Samsung Flat Panel TV had an issue - actually there ended up being a recall. They sent a guy out for free (well after the warranty expired) to replace the power supply once. It failed again and I just went and spent $2.00 on capacitors and replaced them myself. It hasn't failed since and that was a couple years ago.

OK. Here's the story. It's called "Capacitor Plague".

 

KLONK!

 

A major cause of the plague of faulty capacitors was industrial espionage in connection with the theft of an electrolyte formula. A researcher is suspected of having taken, when moving from Japan to Taiwan, the secret chemical composition of a new low-resistance, inexpensive, water-containing electrolyte. The researcher subsequently tried to imitate this electrolyte formula in Taiwan, to undersell the pricing of the Japanese manufacturers. However, the secret formula had apparently been copied incompletely, and it lacked important proprietary ingredients which were essential to the long-term stability of the capacitors.[1][2] The bad formulation of electrolyte allowed the unimpeded formation of hydroxide and produced hydrogen gas.[11]

 

There are no known public court proceedings related to alleged theft of electrolyte formulas.[citation needed]

I notice that you live in CA..JBL has a lot of authorized repair centers in California....check it out:

I have been to two of the places on that JBL list of repair ppl. One has not had a "shot" at fixing it, so it will be off to that shop again. The other, just got weird... I thought they were in business to make a profit!

Thank you all .
