Noisy 206E station ports

[toolman18]

I have a few R3.1 206E's with noisy station ports.I don't want to appear cheap, but is there some way to repair them? only one or two ports bad on each card, but pretty much useless even with one bad port. Anybody ever try to fix these thing's? Thanks.

there is a capacitor that goes bad you need to replace the cap

Ive never done it ,only seen it done so I can't tell you the cap value you need just look at each station and you will see the blue caps there.



I have a stack of them here to that I need to get into

maybe somebody will post the cap value and a source

help the lazy boy out here

where can you buy new caps or old ones? can you use caps from another card pull them out and install them into the workign systme that has the static?

 

[skip555]

what you need to do is look for the value on the cap

that's why in my last post I was hoping somebody would let us know

you could pull ones from a working port in a pinch but why go throu the effort the old ones will probably wind up failing and there you go again Its not loke its a big $$$ item

like I said I do have a stack of them and I plan to figure it out

Ill post back here when I do

(unless somebody would like to post yhe value and a source first )

If you don't have a source for discrete components like caps, there's a store near us that does a lot of component-level stuff. They have a website, do mail-order, and are great to talk to when you need help.

which caps do you chose on the link above for partner acs phoen system? where are the caps in the system? hard to replace?

Unless you are good at soldering, stay away from doing this yourself. There a several capacitors inside the module on the board.

 

[skip555]

you really need a good solder gun or staion and desolding equipment

definatley not the place to learn circuit board repair

I do have a bit of pc board repair experiance and suspect others here do also

It looks like your better off sending these cards out for repair. Too time consuming and tedious.( Repair between $100 & $200). Fix yourself, Insanity! Thanks guys.

100 to 200 to replace a .15 cap ?

15.min labor

insanity not the way I see it

Hi skip555,
Some people aren't as comfortable with pcb repair as others. Plus there is the learning curve. I see lot's of these, as do you. toolman18 may only have one and no parts stock. I do agree with you though (for me).

Hey guys, did anybody ever find out the value of these cap's?. Can you determine which ones bad when it's still connected to the board? (I count at least 3 cap's per port). Maybe you have to replace all three. You do have to admit it's time consuming. I do think you need extra patience when working on a PCB. Something I'm not famous for. What's the cap value?

 

[paul144]

We have a great gadget, I think is is called a "Capacitor Wizard". It detects bad caps that are still attached to the PCB about 99% of the time. Of course, if you have the solder/desolder equipment out, and the replacement caps, you might as well replace them all now and be done with it.
