Re: 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 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.

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.

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

Unplug the power cord, wait for 5 minutes, plug the power cord back in and try to operate the unit.

If this does not work, you will have to get a technician to look at it for you.
