Question about Philips HTS3450 System
I have a Philips HTS3455/98 Home Theatre System, which i have only had for 6 months. For some reason i have no sound. When i turn the Volume right up i still have no sound. If you put you ear by the speakers, you can hear a faint scratching sound. Can anybody help me out at all.
Cheers in advanced
There are two capacitors on the power board that are 470uf/35v. go to Radioshack and buy two catalog #272-1030 470uf/35v radial lead capacitors. if you have soldering wick and a soldering iron, then this will cost you under $3.00. when you remove them, the capacitors have a white strip with a negative sign on it. match this up with the shaded area on the board. put it back together, and it will work, and last a long time. I have this same system, and it wouldn't play any sound. so, I replaced the capacitors. Hope this helps!

Hi all, some invaluable information on this page!
I own a Philips HTS3455 and on Monday night I turned it on and there was no sound. I tried everything imaginable and noticed that the audio was barely audible.
I followed the advice in replacing the 2 capacitors (the layout of the HTS3455 is different to the model in the image) and tested them with a multimeter before and after doing so.
I plugged everything back in and the old problem still exists and as before, the fan in the sub woofer is still not working.
Where to go to from here? Any extra advice?

I had the same problem: my Philips HT 3450 started make some sound like "bizzzzz", and it would start to function normally later. It started with a few seconds or a minute of "bizzzzzz" and then it reached to half an hour, and then the sound died totally!! I went online.
I replaced two black capacitors of (25v), as they were located in subwoofer power board in the picture above, with two new 470uF/35Vcapacitors. Now, it functions perfectly normal, and it is almost unbelievable to solve such an electronic problem requiring an expert on our own, with your great help!! Keep the good work up! And thanks a lot again for the picture and writing.

Thank you Corky1333! Your instructions were right on. I paid $1.29 per capacitor (#272-1030 470uf/35v) and with your image had no problem finding the faulty ones.Now my Philips HTS3450 sounds like new.

Try to change the source (eg. from FM to AUX and back to FM) after the unit has been on for a while and check if you have sound afterwards. Your problems sounds similar to how it started with mine.
Initially it simply took 5-10 minutes before I got sound. Sometimes changing the source from tv to dvd and back to tv made it give normal sound again. The 5-10minutes time gradually increased and after 3-4 months it took about an hour before it started playing sound and at that time also it started to buzz before it actually started playing sound.
For a while I used a hairdryer to heat the unit up which got it playing sound within 5 minutes.
Today I replaced the 2 capacitors with new ones from radioshack and problem is gone.
Corky1333, Thanks for posting the solution !!

I have a Philips HTS3455/98 Home Theatre System, its been with me 4 almost 2 years. The system was working just fine the current had gone off and when it came on i have no sound. When i turn the Volume to max i can hear the song play very faint but before if i increase the volume to 10 it used be very loud. Kindly help me fix the problem its driving me nuts.

I had same issue and replaced caps and it worked for a few months. Now no sound again. Replaced caps again with no luck. Subwoofer standby light red when off and no green light when system on. What else could be wrong?

I have the HTS6600 and replaced the 2 capacitors (very simple thanks to Corky1333), however no volume still. Could it be anything else? No capacitors look blown and the soldering are all intact.

Did this over 2 years ago- was working fine since then, but ive noticed a new issue- now the volume at 'max' is nearly half of what it used to be.
Anyone else? should I replace the capacitors again?

Hi I have a Philips HT 3450 but lost the Subwoofer and speakers. Would anybody tell me if I can take out the subwoofer connection to my panasonic home theator system to hear the sound. ( Panasonic has a 6 CH audio in )

Corky, your solution is a gift that just keeps on giving. My husband and son fixed our system tonight and it's wonderful to be able to hear again without that awful buzzing. Thank you so much for spreading your knowledge.
