Robjrpena,

Did you find a solution to your "red dot" problem? I'm having the same issue :(

Thanks John

Im having the same problem!!! Trying to figure out if my 6 year old cut the little cord that is attached, inside, next to the line in hole.

SOURCE: I have an old but

The most common failure is junction punch-through in the speaker driver transistors.

Identify the audio power amplifier (transistors or power integrated circuit(s). Use an ohmmeter to check for a short from the speaker output to the power supply (on the transistor this would be between the emitter and collector leads). If you have a short, the output transistor is melted and needs to be replaced. There are two transistors to check for each speaker, one to the + side of the power supply and one to the - side. Usually if one goes it ruins the other - even if it tests good, it was probably overloaded and won't live much longer, so change both of them. If this unit used an integrated circuit power amplifier to drive the speaker directly, both output transistors are included inside.

If you do have bad output transistors, you may also have to replace a fuse in the power supply or amplifier circuit.

Failure mode: transistors are made with tiny amounts of chemical dopants placed in silicon layers. After many years of operation at elevated temperatures, these dopants diffuse from their starting point. Beyond a certain point, it doesn't take much of a power surge to cause a catastrophic breakdown. A short-circuit overload could do the same thing by causing rapid over-heating. The clock runs on a different section of the power supply and is not affected by this.

I don't have specific service information on this model, but I would guess it is still possible to find replacement parts at a reasonable price. If an individual power transistor is no longer made, there is probably an improved functional equivalent available.

Radio doesn't work on ihome ih9


Just purchased a used iH9 and I can't get any sound from the radio or ipod. I'm pretty sure I'm doing everything right and I've reset the iH9 by removing the batteries and disconnecting the power. Any suggestions?

Sony Dream Machine clock radio


0) Read the last answer first :) it is the most likely.

1) Make sure that the noise is electronic, not mechanical,

a) Electronic noise comes from the speaker

b) Mechanical nose originates in the clock
(older mechanical clocks only)

c) Clocks come in 3 varieties:
Electronic
Mechanical "Flip Leaf"
Mechanical "Motor/ Gear" driven.

2) Assuming that your clock is electronic, there are
only two possibilities for causing static.

a) Extremely intense electromagnetic interference,
as in radio waves, from a thunderstorm or a powerful
transmitter nearby, such as a HAM radio or even
an active cell phone.

Intense electro-magnetic waves can be picked up by
internal wires within the radio which act as an antenna,
rectified (demodulated) by internal diodes and transistors,
filtered by internal capacitors and the speaker's inertia,
and still present enough audio frequency energy to the
sensitive speaker coil to be "quite" audible and irritating.

This can happen even with the power off, when the
interference is so strong that it needs no amplification !

This happens to my computer speakers, every time my
cell phone rings, and starts transmitting a return signal.


3) The power switch is intermittently shorting causing a small
amount of DC power to enter the radio, the more intermittent
the switch, the more noisy it gets.

This causes my old clock radio to turn on by itself when its
not supposed to.

The cause of the problem in either in the main power/ mode
switch, or in the clock driven switch or relay.

4) Old switches and volume controls get oxidized with time
and/or bridged by products of corrosion. The simple solution
is to clean them using a good aerosol contact cleaner,
available from an electronic shop for about 10 bucks.

Simply spray the cleaner into all the switches and controls,
while vigorously exercising each switch or control back and forth.

Make sure that you use a safe "electronic cleaner" designed
for the job. It must be safe on plastics, non-conductive, good
solvent and it must evaporate quickly. Don't breath the stuff !!!

Typically the spray will contain TF (tri-fluoro-ethane), or some
other freon substitute.

Freon (Di-fluoro-di-chloro methane) is bad for the ionosphere,
now illegal in most countries for that reason.

Also stay away from Carbon-Tetra-Chloride, which is
VERY toxic.

Do NOT improvise, or use acetone or alcohols, which may (will)
melt the plastic, causing the controls to permanently seize.

Get electronic contact cleaner from an electronics hobby shop.

Good luck. Martin
