Question about Panasonic SC-HT700 System

1 Answer

Video problem I've had this system for several years, and have had trouble with it for the past couple years. The video output is poor when I play DVDs. There is a lot of "noise" in the picture when the player reads the DVD for the menu. The "noise" dances on the screen as you can hear the unit reading the disk, and there is a slow line that goes through the picture during playback, from bottom to top. I can never really get it to go away, and the only way to minimize it is to adjust the contrast/brightness on my T.V. I am pretty sure it's not my T.V., but when it's not connected to my t.v., there isn't any problem. Does this make sense? I am to the point it either needs to be fixed, or I need to buy a new system. Please help!

Lines going up the screen usually indicate a synch problem. Do I understand that when you use the DVD player somewhere else it is fine? Have you tried plugging another DVD into the TV. I take for granted here you use the A/V jacks in the front or rear of your TV?

Have you ever cleaned your DVD player with a cleaning disc? The "noise" could be just that. It's also the easiest and cheapest way to maintain your player.

Another suggestion is take the cover off the DVD player and use compressed air on the insides. Dust build-up causes static electricity which can make things go out of wack. TVs shoiuld be cleaned internally as well but there's dangerous high voltage depending on what type of TV you own so I will not recommend that for the lay-man. If you do try it, unplug the TV and wait a good 3-4 hours for it to completely discharge.

I usually clean all my A/V pieces every nine months. The trick is not to let it get "dirty" in the first place so keep the area vacuumed well.

Hope this helps.

Reset Video Output

If you are changing cables or cannot see an image on the screen, you may need to reset the video output to default settings. To reset the video output:
  1. While the PS3 system is in standby mode (red light on the front of the system), hold down the touch-sensitive On/Off button on the front of the system until the PS3 beeps a second time (approximately 5 seconds), then release it.
  2. The PS3 will power up, the Video Output Settings will automatically reset to the standard resolution (or detect the current display output settings of your TV/monitor).

Playstation 3 does not output to my Mitsubishi 62825. It has in the past. I've tried RGB and component. Neither work. Using the same cables it works fine with my girlfriends Sony Bravia. The tv has...

Is your girlfriend's television higher resolution? If so, the ps3 may be configured to output a signal that is too high for your mitsubishi. With the ps3 off, insert either the component or the rgb to the back. The turn on the main ps3 power switch so that the red led turns on. then hold down the 'power on' button. it will beep initially, then beep after about 3 seconds. This simply resets the output to the connected cable in a normal resolution.

If this fails go to settings>video output> and play around with the settings there. note you may have to do this on ur girlfriends tv to be able to see what you're doing...

I had the same problem with mine - eventually it just stopped playing anything. Turns out that the HDMI from the Tv to the CS3 was actually 'reprogramming' my CS3. My flatmate gave it a system reset and that seemed to fix it.

I now have the problem that when I play blueray DVDs with dolby digital from my PS3 via optical digital i get the sound cutting out intermittently for a couple of seconds grrrrr.

Over a year ago now I purchased a Yamaha Pianocraft RX-E700. This system works well save for when I plug the auxiliary output into the headphone jack of my laptop (in order to play song through it) ...

Probably a poorly shielded or grounded cable. Also check the laptop to see that it's audio output is sufficiently high.

Shouldn't the ouput of the Yamaha go to an input (nicrophone) on the laptop?

Ps3 wont show up on tv

Hey i just posted i have the same problem as you do but then I checked the SONY PS3 website and it solved my problem. Try resetting your video output. I'll paste what it says on the PS3 website but if that doesn't solve your problem go to the website. They have a bunch of troubleshooting solutions for this problem...

If while manually changing the Video Output Settings, the screen remains blank for more than 30 seconds, you may need to perform the following steps to reset the Video Output Settings.

  1. Make sure the Component AV Cable is connected to the [AV MULTI-OUT] port on the back of the PLAYSTATION 3 system.
  2. Connect the other end of the Component AV Cable into the video and audio RCA jacks of the TV or display monitor.
  3. While the PLAYSTATION 3 system is in standby mode (red light on the front of the system), hold down the touch-sensitive On/Off button on the front of the system until the system goes into standby mode again . (So the light cycle would go from: red light to --> green light --> then back to red light) This will ensure that you have held down the On/Off button long enough to reset the Video Output Settings.
  4. Turn ON the PLAYSTATION 3 and once the system finishes powering up, the Video Output Settings will automatically be reset to the standard resolution (or detect the current display output settings of your TV/monitor).

My speakers have almost constant crackling noises

Hello, there is no chance that you can fix this problem by replacing speaker wires. Resoldering the output stages as well as area around the microprocesor could be the efficient solution. If you need more info please advice.
