Phillips HTS3410D audio

I have a phillips home theater (hts3410d) that sound can barely be heard. Right channels seem slightly louder than left, but all are still barely audible even when turned to max. Any solutions or ideas? I found a few solutions involving cap replacement but for a different model. Not sure if this would help mine or not, but the pics provided in other post do not resemble my system at all. Thanks!

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.

HTS3410D power light keeps blinking

This seems to be a common problem with this model. It seems as though there are about FIVE electrolytic capacitors in the power supply PC board that have failed or dried out.

They can be replaced by someone that has the dexterity, knowledge and tools to de-solder and re-solder PC board components. Otherwise you may seek a local electronic technician. The parts cost about $5.00. Labor may run you $30 or more.

Hope this helps. I also am looking for a remote for mine, if someone has a dead HTS-3410D.

Thanks!

Phillips hts3410d no sound VERY dim led

Have you had any thunderstorms recently in your area? if so, this could be a pulse sent threw your system form an electrical storm. this happens often during dangerous thunderstorm activity. Also, your electrical wiring in your home can produce this as well due to a faulty circuit breaker box or lose ceiling fan hook ups. the best scenario could be a defective product. this way, you can get a full refund or a replacement set up.

Philips HTS3410D home theatre system. DVD is stuck inside - won't play, won't open. any ideas?

Power off the system
Unplug the power cord
Wait 5 minutes
Plug back the power cord
Power up the system
Press the open/close button
Load a DVD and play

If the tray still will not open, the cover will have to be removed and manually operated. You may have to have a technician look at the unit.

Please rate this solution - Thanks

Not powering on

I solved this problem on my HTS3410D.

Inside there are two circuit boards, the power supply board and the audio/video board.
  • First, unplug your unit and let it sit for a few hours.
  • Now open the unit up, and unplug all of the connectors going to or from the power supply board. You can easily tell which board is the power supply board because it's the one the power cord plugs into.
  • Unscrew the four mounting screws that hold the board to the case.
  • Using a pair of needle-nose pliers, squeeze the two white plastic clips that hold the board to the case (one at a time), while gently lifting the board away from the case.
  • Now that you have the board out, feel the tops of all the capacitors (they look like this). Healthy capacitors should have a totally flat top. (There is probably one that is covered in some sort of heat shrink, so you can't feel the top.)
  • One capacitor most likely has a slightly bulging top. That is the culprit.
  • Using a soldering iron, carefully remove the busted capacitor, making sure to note which side the stripe is on.
  • Buy a replacement capacitor at Radio Shack or www.digikey.com that has the same capacitance (e.g. - 1000uF) an equal or greater voltage, and an equal or greater maximum temperature.
  • Insert and re-solder the replacement capacitor in the same orientation as the one you took out, then trim the excess leads.
  • Reassemble your system, and you're done.
The capacitor that died on mine was 1,000uF, 16V, 105°C. It was located fairly close to where the power cord comes in to the board. I replaced it with a 1,000uF 50V capacitor, and the system powered right up like a champ. The entire process took me about an hour.

I hope this helps some other people have similar results.
