I appreciate it.

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 HTS3450/37 replaced the caps got ride of the buzzing but still don't have sound on sub center channel or left front any ideas

Hi Gerhodes. The answer above is correct with one exception. The reason this has been found to be such a problem with the Phillips HTS 3450/37 model is due to the fact that parts positions numbered "C987" and "C989" are not powerful enough . If you take the "Black backplate" off (the one that the otherside actually shows outside when asembled. Right about where the plate was removed between the "Metal Wall" as it resembles and the "Main Power Conductors" which are covered by the metal top plate and wrapped in yellow or some other color tape. So, as you see that area, at the back are 4 capacitors. Two are small and neither of those two are the same size as each other or the other two in that area. There are two capacitors of those 4 that are set in a diagonal position from each other, They are the same size as each other. Those are the ones that you want to replace. They 470uF/25v. What creates the issue is that these capacitors are not large enough to handle the power needed. So, when you replace it you want the equivalent of a 470uF/35v to supply enough power. Once you replace the weaker ones with the more powerful capacitors ensuring to solder on the opposite side of plate (green side), you should be good to go.
Good Luck,

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.

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.
