Question about Audio Players & Recorders

It has power but won't work!

It was working perfectly and all of a sudden a loud noise, and powered off. Now when I turn it on the mute sign flickers a couple of times and turns off. It is not the fuse because it has power, but I don't seem to get anywhere. Help! I have a Kenwood Receiver KRV5580. It was working alright but all of a sudden the display does not show up on powering up. The power is on but the 'Muting' indicator blinks for sometime and nothing seems to work. Please help ASAP!

    I bought my amp around 1993. The other day, the radio was on and everything was normal. All of a sudden, for a few seconds the radio reception sounded a little fuzzy, as if an airplane had interfered with the signal. After a couple of minutes I noticed that there was no music playing. I thought that maybe there had been an electrical surge, but everything else was on. So, the power is plugged in; the CD player that is plugged into the amp comes on, but no lights come on on the amp -- no stations, nothing.

There is a problem with the output stage of the amplifier section and the whole unit is in "protect" mode. This means that the output section is turned off. The output transistors are the likely defective parts here. Expect a repair cost of $15-$40 in parts plus the local labor rate.

If you have extra used cartridge, try replacing the cartridge. If there's no noise, change your cartridge with a new one.

The tv usually turns on but all of a sudden it won't. When it does turn on it makes a loud noise like a boat. Someone told me its the fan but I'm not 100% sure though. The noise stays on until the tv


Sounds like the motherboard on the TV has failed. Would recommend replacing the TV or taking it to a TV repair shop which may cost more than just replacing it.

Tv making loud buzzing noise


A common cause are failure of decopling capacitors in the audio section, and or the circuit board power distribution that feeds the audio board. Most of the capacitors are surface mount components. The standard fix is to start by changing the circuit boards that have the defective parts.

If the set is under warranty, call for warranty service. Out of warranty service is expensive for these TV sets.

It just will not turn on, I have had it for 4 years. It worked perfect all the time no problems. All of a sudden one day went to turn it on and it just wont go on. There were no signs leading up to this...


The power supply board has failed. Very common problem on this model and especially this brand. Buy another power supply module that is compatable....different modules used in the same set.

Subwoofer noise


You didn't say is your sub active or passive.If its active first check signal cables from theater system,power line of the sub, it has to be the same phase as the system.If its passive take a voltmeter disconnect the sub from the system and measure for DC voltage on the SUB output on the system when its OFF.If DC voltage is present your amp is damaged.It can also be that the preamp circuit for the sub doesn't mute the input when unit is on stand by and you hear frequency of your power supply (50-60Hz) on the sub
