Phillips HTS3400 blinking red light

A few days ago the speakers started making a terrible noise. Sounded like screaching and a lot of bass. OUT OF THE BLUE. Now the thing won't turn on. I've unplugged it for a few min. but when i plug it back in the standby light blinks kinda fast. We dont turn it off when we go to bed we just turn the tv off. It must have shut itself off during the night.

    I have the same problem with mine. Except mine started one day when nothing was playing it was just turned on. I heard a noise and noticed the light flashing. I unplugged the system but as soon as i plug it back in it starts back. The power/standby button doesnt respond the only way to turn the system off is unplugging it.

There is a capacitor on the power supply that has gone bad, it is a 1000 mf 16v cap and you will notice the top is bulged up a little bit. there are three in a row and this is the center one. Radio shack replacement part for $1.73 and you are back in business. Tim

    twood95 is right. I have the same problem. Replacing 1000mfd/16v solved my problem. Thanks twood95.

    I, too, had the blinking red light. A capacitor on the power supply had a bulging top. I replaced it and 4 others in the area ( no good reason for the extras) and now I am humming along with theme music.

Many other users reporting the same problem using different description. Mine was doing this same thing and now just sits there and buzzes until I press the power button and then it's quiet for a few seconds. I've taken my power supply loose, but there isn't anything obviously wrong and is more than likely a $3 part like a capacitor that has gone dry.

There is a user "meelous" that said he had a fix for this, but he hasn't responded yet. Look at the other posts using the HTS3400 and watch for a real solution, other than throwing it away and doing without.

Good luck.

the unit seems to be going into freeze throntone. this is caused by inpc problems with the di po chip if you could take out the back up capacitor im sure it would return to normal to fix it your self disconnect all speakers and input cables leve it to sit for a couple of days and re try it with no cables connected if this does not work it will have to go into the shop

best of luck

Phillips HTS3410D audio

You seem pretty anxious to perform surgery. Have you done traige yet?

It could be something as simple as a malfunction on a heaphone jack connection.

DO headphones work? Try using FM as the most basic source.

How do we know the internal audio is present and sufficiently loud to drive the speakers? If you have a tape deck or a TV with audio in connections, run an RCA jack to it and see if there's something there to listen to. No signal = no speakie = something other than the power amps failing = not those caps you read about.

BTW: don't use Maximum volume while troubleshooting. If you finally do touch the one thing causing the problem you'll probably launch the speaker cones right out of their enclosures and have to start all over again with blown speakers.

Buzzing noise coming from speakers in phillips mcd718 micro theatre after having installed insignia 52 plasma hdtv. Just happened about four hours ago.

possibly a ground issue , do you have everything plugged into a line conditioning power strip? are your speaker wire,s plugged into the red and black speaker connectors propperly,and are the positive and negative wires in the right order? also check that the component or hdmi cables are not the issue , but usually the buzzing noise would sound more like a ground issue , I hope i was able to help you solve your issue if not feel free to contact me again so we can tackle this issue together , if i was able to help you pleace leave a nice review ,thanks alot ,Sincerely glenn mayer

Fox International sells the speaker casings. The plastic casing for the main unit would have to be procured by buying a broken HTS3400 off of eBay/other online seller, and replacing from there. Myauctionsonline was once selling a broken one for about $30 including shipping.

Power short/ bad fuse?

I had the very same problem. The dreaded blinking power light. I also dabble in electronics. I found that all that was wrong with mine was one bad cap. There are two 1000uF(microfarrid) 16V(volt) capacitors in the mid section of the power board, right next to each other. One was bulging on the top. They have an "X" on top. I replaced it with a 1000uF 35V capacitor from Radioshack. They did not have a 16 volt. (Never go down to a lower voltage) The capacitor I got was larger than the old one but I gently moved over the parts around it and got in there. After replacing this one capacitor, which I got for $1.72 tax and all, I plugged it up and no more problems! It works great! I hope this helps someone else.
