Hi, somwhere one the back of the unit there should be a small red push button see if it is poped out if so push it back in , if non that means the sound amp inside the unit has over heated and blown the sound card . therefor you would have to replace it . hope this could help you.

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. As far as installation instructions go; you have to have some soldering experience, first. You will also need some type of de-soldering device, be it a solder ****** or solder wick to remove the caps. Make note of the polarity before removing. Then it is just a matter of popping the new ones in (they are slightly larger than the originals so they might not go all the way down flush with the PCB) and soldering them back in. Make sure you do not make any solder shorts or your system will be toast! Your unit will be as good as new and will probably last forever now.

When i turned on my Samsung LED television all i get is a blank grey screen with no sound. i have Comcast but my other tvs are fine. i can play a dvd on it with sound and screen, no problem and the menu...


Follow the cable from the Comcast set top box and see where it is plugged into the tv. Check what that jack is labled and then select that option on the TV menu. My guess is that the tv and dvd are not both on component 2, if the are then the set top box is not connected directly to the tv but to the DVD unit. In that case, if the cable set top box is connected to the dvd, then you might need to put the tv on ch 3 (or maybe 2 or 4) or you may need to switch a setting on the DVD box or remote that selects the TV/DVD option.

No sound through Bravia speakers after BOSE removed.


Did you ever have audio through your tv before?
It's likely that your Comcast cable box was connected directly to your Bose system, and not your television.
You'll need to check the connections from your cable box, to your television.

Go video model dv-241 hook up to make vhs to work


There are a fews ways of accomplishing this.
It sounds like you may reversed your cable connections. Lets try these steps.

On the back of your cable box and your Go video VCR/DVD there are two coxial connections an (OUT) and an (IN):

Step 1. Connect the coxial cable from Comcast to the (IN) connection on the back of the cable box.
Step 2. Connect one end of a spare coxial cable to the (OUT) connection on the back of the cable box.
Step 3. Connect the other end to the (IN) connection on the back of your GO Video box..
Step 4. Connect one end of another spare coxial cable to the (OUT) connection on the back of your Go Video Box.
Step 5. Connect the other end of the Coxial cable to the back of your TV.

I hope that you find this solution helpful.

Sony Bravia Dav-HDX279W and comcast HDTV Cable box connection.


Like above, use an optical connection (need fiber optic cable) or a coaxial connection (single RCA cable). HDMI might also work, but I personally haven't checked. Connect the audio outs from the cable box to the audio ins on the home theater. The TV will only need a video connection from the cable box, as well as one from the home theater (for DVDs, onscreen menus).

This discussion can help you set up the universal remote.

Don't worry about sending the TV audio to the Panasonic. Just send a digital audio signal from the cable box to the Panasonic.

DVD - Panasonic connected via HDMI
TV - Panasonic connected via HDI
cable connected to cable box and TV. But you will not really be using the cable connection to the TV (TV Tuner) since you will want HD feed from cable box through HDMI input on TV.

You aren't concerned about feeding the TV speakers because your audio will always come from the home theatre.

Note that some components don't feed audio through HDMI, in which case you will need to use optical digital audio.
