Philips HTS3455/98 System "NO SOUND" PlZ Help!!

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!0ccab8c.jpg

Philips HTS3450 System Problem buzzing/clicking sound on startup. Now nothing.

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.

Philips receiver hts3450 was stolen but I have all my speakers and subwoofer.

Without doubt the Philips had an amp built in for the subwoofer. So that when it is connected to the TV the sound signal from the TV is just too weak to power it. My advice would be if you can't get a another receiver is to look up the specifications of the it. You should then be able to find a suitable amp that will power the subwoofer for the TV from those specifications.

How to solder capacitors?

Soldering capacitors is not difficult. First you will need access to the rear of the printed circuit board which has all the solder connections. I don't know which type of caps you are talking about but you must be sure to make a note of which way round the existing capacitors are seated on the board. Large value caps usually have two solder tags at one end or wires coming out of each end. If there are two solder tags at one end then the plastic sleeve on the can will usually have a series of dashes down one side - this indicates that the negative connection tag is on that side. Alternatively you may have a series of plus signs to indicate the positive connection. Caps with a wire at each end of the can will also be marked with plus and minus signs to show which way round to connect. You will need to make sure you replace the caps the correct way round.

For a soldering iron about 25 watts is usually fine for this type of work.

Suggest you also use 'solder wick' to remove the existing solder when you take out the duff caps. This is used by placing the solder wick over the joint and applying the soldering iron to the solder wick. After a short interval the solder melts underneath the wick. It is drawn into the wick and leaves a clean board. You may have to clip off any solder laden wick if there is much solder to remove.

With all the solder removed you should be able to lift off the old caps and replace with the new ones. For good joints make sure that there is no corrosion on the tags or wires. Failure to do this will result in what is known as a dry joint. It looks like a good soldered joint but will not conduct electricity.

When soldering in the new caps make sure you use resin cored electronic component solder. Other types have a high melting point and will result in bad joints. Apply the solder between the iron and the connection you wish to make. As soon as it flows and makes the joint remove the iron. You may have to apply solder on both sides if it is a tag connection.

Try not to heat up any semiconductor devices with hot solder. The usually require lower wattage irons to prevent overheating.

Just a hope - when replacing caps with a wire at each end you can sometimes clip off the old wires close to the can and use the wire left in the board to connect the new component.

Happy soldering.

No sound after power surge

This solution was posted in another users topic about the same issue and it works.

The circuit boards inside the subwoofer contain the capacitors that need to be fixed.

You need to purchase the 470uf 35v replacement capacitors qty(2), which you can do at Radio Shack-catalog #272-1030 $1.33

You also need a soldering kit, Radio Shack also sells these for 7 bucks (i recommend the 5 piece kit).

After you get the goods; remove the back plate of the subwoofer and disconnect the power wires, unscrew the circuit boards and look at the pic below to find the 2 capacitors we are replacing:


Check youtube for quick and simple instructional videos for removing old soldering on circuit boards and applying new solder.

*IMPORTANT* Make sure the black stripe line on the capacitor matches up with the shaded portion of the circle where you place the capacitor.

Once you are done reconnect everything and do a test to check if it is successful, it should be; it worked for me and i never used a solder stick in my life.

I have a Phillips hits 3450 surround sound system.

Usually the case that the subwoofer in the two capacitors are burning 16v 480nFplease check avsystemparts.com
