Sony TA-AV421 Amp

go to the shop and ask for USB/HDMI cable

2.5 feet long enough? They are kept short to reduce data loss.

I have just purchased a Audiosonic Soundbar KW-3508 and connected it up to an existing cetre speaker connection but could get no sound.Any suggestions?

It's just a big amp with no controls you would change during normal operation. There's no remote. You don't name any source or if you even HAVE one attached. THAT would be a good place to look for missing sound.

Set the BTL/Normal switch on the back to Normal. In fact, any switch or knob with BTL, set it to whatever choice is NOT BTL.

Hi and welcome to the site,

Initially, on a completely dead Sony TA-N9000ES, primary suspects to be checked would be:

• 8A F1 fuse;
• primary winding of T1 transformer;.
• fusible resistors R816, R817 and R818.

Good luck and thank you for asking.

needle nose pliers to turn it down,find another knob there pretty common even if you had to use a drop of super glue.

MAKE SURE THAT YOUR POLARITY IS OK FOR THE SPEAKERS.TRY TO TEST THE VOLTAGE BEFORE STARTING THE ENG THEN AFTER AND SEE IF ITS THE SAME OR MUCH MORE.

Your in luck there is a user guide online that has all you need to know.Here is the link

an amp of this size generates alot of heat internally when in use as these use mosfet ICs and can get very hot.
your problem is most definately dry solder joints and possibly quite a few at that.
i've repaired quite a few sony surround receivers with similar problems and have all been down to dry solder joints.

hope this helps.

The flashing light is indicating that a fault has been detected, and it is staying in "protect mode". First disconnect all cables from the processor (except the power cord) and then power up the processor. This will eliminate the possibility of a shorted cable or a problem with any connected components. f the light still flashes, there is an internal problem and the processor will require profesional service.
