As I found somewhere on the internet; there are two 470uF/25V capacitors on the power supply board in the sub-woofer that are the cause of buzzing, crackling and then eventually no sound. Go to Radio Shack and buy two Catalog #: 272-1030 470uF/35V capacitors and change them out. They are in the middle of the Power Supply PCB and are close to the long flat aluminum heatsink. Make sure you match the polarity properly when replacing. Your unit will be as good as new and will proibably last forever now.

Why won't my TV sound go through the Hts 3450?


Wide open one here. Is your tv coming in direct from the wall or do you have a cable/digital box that you need to get the signal from? If you have a box then make sure you are plugged into the audio out on the box and on the HTS you are on the audio in. There will be a left and right. If you have the sound to your tv then you can plug into the audio out on your tv and again plug into your audio in on your box. If your tv has an option for external speakers then you need to make that adjustment on the audio menu on your tv. Also make sure that the proper channel is selected on your HTS and that your audio output matches your selection. Hope this helps but I will keep an eye out for further posts.

I have a philips hts 3450 i just bought and i didnt get the speakers is there a way of hooking it to my tv and get it to work


Speakers are an integral part of any home thetre system and are, as such, effictively useless without them. You will need to attach some speakers to it in order for it to work as intended.

Common problem with the Philips - here is how to fix this issue:
There are a few possibilities.
1)You can connect a red and white AV cable (or the red and white portion of a red, white and yellow cable) from the TV Audio OUTPUT to the "Audio In/TV" portion of the HTS (NOTE: Many TV's do not have an Audio OUTPUT).
2)You can connect a red and white AV cable (or the red and white portion of a red, white and yellow cable) from the Audio OUTPUT of your cable or satellite box to the "Audio In/TV" portion of the HTS.
Note: Using a red and white cable may not give you sound on all 5 speakers.
3)Get a digital audio or SPDIF cable and run it from the TV, Cable or Satellite Box's Digital Audio OUT to the "DIGITAL IN" of the HTS. This will give you the best sound quality. When using this (or any of the other) type of connection, press SURR until you get sound from all 5 speakers.
Also, the manual can be obtained from www.usasupport.philips.com
