T610 Speaker Problem

I'm positive it is something that broke off. I took a better picture,
please take another look.

Hmm - you could be right. The question remains as to whether this is the
cause of the problem or whether the person you bought it from caused this
damage when trying to repair something else. These components do not
normally just fall apart!

I know they normally don't fall apart. I think it's safe to assume that he
inadvertently broke this piece off while trying to remove some components in
the housing change process. Some parts involve a little prying to remove.

Those 2 prongs are connectors for the speaker. I think the broken
resistor/chip is directly related to the problem of the non functional
speaker. The question I was asking is how do I fix this, not how this came
about.

Well, the basic answer is:

You need to get a component of the correct type and value (never had to buy
one, so I am not sure how easy it is to obtain small quantities - normally
they would come on reels of 5000. Maybe Maplin or RS or whoever can sell you
10 or something). The tricky bit here is the "correct value". As the
component is missing, it is hard to say what it was but it could well be a
chip resistor or capacitor. Are there any markings on the equivalent
component on the other board? If it is just a solid colour, you will have
difficulty working out what it is.

Then you need a soldering iron with a tip of the correct size and which can
supply the correct temperature. You might get away with the usual
general-purpose ones that people often have, but it would not be ideal. You
would be best off if you had a decent temperature-stable one.

Then you need the correct type of solder (ie the thin stuff) and preferably
some solder-braid and maybe some flux to clean the solder pads.

Then you carefully use the iron and braid (and maybe some flux) to remove
the remains of the old component and clean the pads, being careful not to
over-heat them as they can come loose from the PCB

Actually, a quick google-search came up with the following rather good page,
so just read this
http://iridia.ulb.ac.be/~fvandenb/wo...-GuideV1-3.pdf

Follow their advice and replace the component with one of the correct value.
If you have any other scrap boards (of any type) with similar components, it
would be worth practicing replacing a component on one of these, if you have
not done this type of soldering before.

I assume that there is no chance of warranty on this item already - if you
have opened it then you have almost certainly voided it if there was one and
replacing a component would very definitely and very obviously remove any
chance of any warranty replacement or repairs to the unit. I'm not sure
where you would stand operating a home-repaired radio transmitter either,
strictly-legally speaking You might be breaking some rule in the
small-print of your network-operators contract....
