Question about Philips HTS3400/37 System

Open Question

I am trying to fix my Philips HTS3400/37 (power issue/blinking light/service manual)

I have the blinking light issue mentioned a few times here. I have been trying to troubleshoot it. I have found one bad capacitor (C985) And found that no voltage on lead 12 of IC952. I called Philips to try and get a service manual but they will only charge me to replace the system. How frustrating. I can easily get the parts I need if I can figure out where the problem(s) are found. Have any experience with this problem or know where I can get a schematic of the power supply board? ANY help would be greatly appreciated! Thanks!

    I noticed one day that the light was blinking on my dvd player and it wouldn't come on. I don't know about schematics or anything but I read from a user of this site that it was probably a capacitor. So, rather than send it to a professional and pay $100+ to have it fixed, I replaced one obviously ruined capacitor on the motherboard and it worked like new. (C984 . . I think . . .) It cost about $13 for the parts and s&h and took me all of 45 minutes. I don't know if this can help but I just wanted to confirm that post I read. I did fix it by only changing one capacitor.

SOURCE: 470uF capacitors

The 470uF/25V Caps are in the middle of the PCB alongside of the slab-looking aluminum heatsink. You should be able to see that the tops are popped up and the glue around them is brown from overheating.

SOURCE: Philips HTS3450 - high pitched humming noise until warmed up


Read one of my posts:
I used a hairdryer and blew hot air into the grill on the bottom of the subwoofer enclosure which reduced the delay time from ~1hr to 5 minutes. (The high pitched noise was still there for about 1-2 minutes)

Philips HTS3010 not powering on and the power button LED keeps blinking and and click sound from DVD while power Led blinks Help me on solving it.

Hi,Even your DVD is newer version but would you please try the following solution that I provided for someone else....It may help..Because ,when a capacitor in the power circuit board fails, power led blinks and tray sticks too..So take care.
it is a common problem on Philips DVP 630/642/37 series DVD players..As Power problem..A blinking red power button urges you that there is a malfunctioning capacitor in the circuit board.

This is actually surprisingly easy to fix. but it needs soldering iron before.any attempt. Here are the steps .The decision to try this is up to your own discretion and may be a last ditch effort before throwing the player away.
Unplug and take the metal cover out (plenty screws on side and on the back): Check the board to see if capacitor numbered as "C316 "is bulging-/leaking. If so, get a 1000u capacitor >=16V and replace it..
If you cant do it find a handy man nearby you and ask him to do it..It takes just 10 minutes but you must obtain the capacitor from Radio Shack (2.00 USD) before you begin..

Take care and do not forget to rate me too..Thanks

Clip light on Multimix 12 Firewire always on

I have just gotten the same problem. In my case it worked fine for almost three years and one today I turned it on and this loud humming noise + the red clip light always on appeared. When I hit solo button on channels 9-16 the humming disappeares but the light would not go away. With solo on humming get louder on the mic channels individually (1-8). I am puzzled... No solution so far

Apex DT250 wont turn from standby (red light) to On (green light)

The DT250 has one or more bad 470uf 25v capacitors. You should replace all four. Look at some of these youtube videos for how do do the replacement.

Order 4 new 470uf 25v capacitors from P/N P10274-ND

Use first class mail as your shipping method. Will be under 10 dollars total.

Sony Dav-C770 blinking standby light product will not function

I had the same problem, red blinking light after owning for several years. I decided to replace the capacitor at C914 to see if it would work, and it did. Apparently that capacitor is prone to failure. Since this seems to be a common problem, I created a web page detailing the repair. Hope it is helpful. Repair cost $1.39 + tax.

When i push power light jus flashes and nothin powers up

there is a single capacitor on the main power board that has burned out. I found another site that had a great step by step with pics but now cant find the link...if you take the unit apart and look at the board where the power cord is your finger across the top of the black and silver capacitors you will find one that is slightly buldging up...that is your problem child...a new one cost a whole $1.62 at cost me 3 bucks for the solder since I couldn't find took about 35 minutes to repair...the hardest part is flipping the board over and melting the correct solder point around and see if you can find the web site I mentioned he did a great job of explaining it...his fix was for a slightly newer model but it was spot on...good luck

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.

Blinking standby light system will not turn on

I was having a similar problem and determined that there was a short in the speaker leads for the center channel speaker. The leads to the speaker were touching, after being moved, slightly while housecleaning. Once short was eliminated, unit powered on and worked with no problem.

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.
