Question about Audio Players & Recorders

Open Question

My Sony CRF-5100 radio only has static when I turn it on. I think a good cleaning is needed with contact cleaner. I am not sure of the best way to take it apart so that I can get at the tuner dial to clean it. I have a copy of the original service manual that gives detailed instructions on how to completely take it apart but don't need to go that far. Instructions on how to disassemble it to just where I need to go would be appreciated,

Radio won't turn on all the time. It works fine when it does. I cleaned the on off and it still does this. HELP


Try spraying electrical contact cleaner down the shaft of the on / off / volume control (after removing the knob itself) with the radio unplugged. Operate the knob if possible to "work" the cleaner into the mechanism - or gain access to the control from the back (inside) of the radio. These types of controls have an open snap action switch that is often piggbacked on the mechanism that may be visible or behind a tin protective cover. You may need to dismantle the cover to effectively flood the switch with cleaner. Read the label of the contact cleaner before using - as some may attack plastics, etc.

Good luck!

How do i stop the intermittent static?!


Static can be caused by a poorly charged or bad battery. Try cleaning your battery contacts with a pencil eraser, on the battery, radio, and charger. Then recharge the batteries and see if the problem still exists. If so, try a battery from a known good unit and see if it stops the static.

If the battery is not the issue, you could simply have environmental noise. RF (radio frequency wave) in the environment is a common problem in urban areas. If you are using the radios in or around computers and other electronic devices, coil the cords to these devices and make them tidy. RF noise can be emitted through the cord like it is an antenna of sorts. Coiling will reduce this effect.

If your radios have PL capability, aka private line code, interference eliminator, turn it on, or change the setting. This should block out unwanted noise and interference.

Best regards.

Either you have a poor earth connection or you are getting a lot of static from the records you play. The best way of getting rid of static is a spray you can get for cleaning records. Search on-line for Anti-Static Record Cleaner.

The push buttons give off static when pushed and have to be held in place to hold a station! Is there a remedy for this? The problem actually started soon after I got it.


A can of contact cleaner will usually fix the static problem unplug the unit, and use the spray tube nozzle from the back side to reach the push buttons, you will have to push them in and out to clean the contacts on each slide switch. while you are at it clean the volumne and tone pot, the same way. a good brand of contact cleaner will not affect anything in the radio but will remove any dirt from the contacts. This is the usual cause of a loud static noise in most radios. A poor contact.

As far as the push buttons not staying in, I notice the red wires from the transformer are lead around the front of the radio, perhaps one has lifted enough to block the buttons from latching. Or the latch on the buttons is worn or broken away.

Excessive static


Constant static is a sign of either a bad/low battery or a defective radio. Sorry. You might try switching the batteries from a known good radio to this one to see if the problem is solved. Clean your battery contacts with a pencil eraser to assure good connection. If changing the battery does not solve the problem, the radio is defective and will need retired.

Best regards.

This is an easy fix with a can of volume knob cleaner i think its called. You should be able to get it at radio shack. You just spray it into the volume knob and let it dry. The instructions are on the can.

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
