Question about Audio Players & Recorders
Hi. I have a wharfedale IS73. The sound keeps cutting off after about 5 minutes whether it's on radio or cd. Makes a noise as though it is switching it's self off and keeps doing it. I've turned it off overnight but not is still the same. Any ideas if this is repairable? Thanks

All Aiwas are prone to this problem. The doors are a real pain and easily give up the ghost. I have 2, both probmatic in this direction.
I have spoken to others about this problem. Seems no easy fix.
Have you in your case, tried leaving and old tape in the tape part of your unit . The noise you hear, usually starts when tape unit area doors are about to pack a wobbly. Unless under warrenty, proberly,
not worth getting fixed. It seems something gets weak in the activation part and get a mind of its own. Very common after about 3 yrs of ownership. All the best: jamz

When the initial set up ran for the DVD recorder it set the correct time and, I assume, the correct date.
However, I had problems with the display and went through various settings until I solved the display problem.
Unfortunately, during the process, which included disconnecting the power, the clock was reset, starting at midnight and 1st January. There appears to be no way to access the clock.
How do I get the recorder to display the correct date/time?

This solution may work for other Wharfedale DVD recorders as well as the DVDRHD400F.
Use your Setup button to acces the 'Setup' menu.
Choose the 'Preferences' menu.
Choose 'Factory Defaults' and click on 'OK'.
The recorder will restore the factory defaults and the first screen it takes you too is the 'Initial Setup' screen where it asks you to enter the correct date and time.

May work on similar dvd recorders. Would help if Wharfedale included this in their users manual.

Sounds like an internal loose connection somewhere, possibly anywhere, a connector on a pcb, a dry solder, loose pin on an IC. Tough for an end user to solve this, would entail opening the unit and investigating. I checked the rear panel in the op manual and this model has no ribbon connectors else i'd have asked you to check them.

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:
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
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

the problem occurs in ur main board...check all tge resistor in board...the faulty resistor will; allow high voltage to the main board and affect it
