Panasonic SC-HT900-problems with surround sound mode and digital input

I have had the Panasonic SC HT900 for about 3 years (out of warranty). The problem I am having is that the surround sound mode on TV and Tuner and the digial in mode all will not work. If the TV and Tuner are in stereo mode (just the front speakers and center speaker) they work fine. The DVD/CD mode sound works fine in all modes (stereo, surround sound, dolby digital). The problems occurrs when putting the system into the digital mode or the surround sound mode while the system is on the TV input or Tuner. Sometimes the sound will work for a few minutes and then there will be a "pop" noise and the sound will go out. If I change the mode to stereo then it will work again, but as soon as you change it back to surround sound the sound will go out. I took it to a repair show about 2 months ago and they advised they could not find a problem. I brought the unit home and it worked for about two weeks and then started messing up again...over the next few weeks the problem got worse and then finally the surround sound and digital modes will not work at all anymore. I have checked all speaker connections and as I previously stated the DVD/CD surround and dolby digital modes work fine. Any advice you can provide would be appreciated. Thanks, Greg Edmondson

    Gregory, it seems like I have the same exact problem on the same unit. Have you been able to repair yours since your post?

    I too have the same issues. I can get a stable state on only one setting. The Surround feature has to be off and the SFC must be set to flat. If I leave this horrible system set there, it works fine. Of course there is no sound coming from the two rear speakers.

    Anytime I try to activate any other SFC setting or put it in Surround Sound mode it pops and squeals and pukes out horrid bursts of static. It's insidious and Panasonic is absolutely aware of this issue yet they will do nothing.

    My system is a few years old and has been like this since month 4 or 5 of having it home. I allowed the one year warranty period to run out and never took it in for repair and of course, Panasonic refuses to admit they made a pile of junk and stand behind the mistake.

    If there are enough of us willing to initiate a class action suitagainst Panasonic, I would be happy to organize it. I can be reached atemassist@emeryemery.com if you would like to join in on that idea.

    Does anyone have any idea parts could be replaced on the logic board that might resolve these problem and bring this systme to fully usable state? I am quite handy with a soldering iron and I am sure I could fix it if anyone could tell me which parts are causing this problem.

    Thanks in advance to anyone who might offer some information.

When I play a DVD it works fine and the problem comes and goes...sometimes at the worst time (i.e. during SuperBowl this last year). I have had two repair shops look at it and both advised they could not figure out what the problem was and that the home theater in a box systems are only made to last about 3 years or so if use reguarly. They said that they are made with cheap parts and these parts get out and burn up or wear out easily. I am staying with this system until it completely quits on me, as long as it still plays DVD's fine I will keep it for my kids to watch movies on. Good luck with your system.

I tried to fix the popping defect to no avail. I thought if i powered the internal subwoofer fan to a different power source that it would solve the issue. Although the fan spins faster connected to an external power source, and it keeps the sub motherboard cooler, it still pops (less often) and loses sound. The fan just cools it faster so that it can happen again. The working fan only extends the functionality twice as long but still has the same issue. I did notice on the subwoofer motherboard that there's a dark spot near a few transistors/regulators. I suspect at least one of them have already failed causing the system to overheat anyway. I also suspect that if I keep using the system, those will also fail. I will never buy anything Panasonic and neither will anyone I know (I'll tell them all not to). Don't buy this product.

Hi I have a panasonic theatre surround system model number SA-HT900 but I need a remote for the unit but can't find one anywhere . There is another model a panasonic SC-HT900 will the remote for this...


The remote for the SC-HT900 will work with the SA-HT900. The SA-HT900 refers to the model number of the amplifier of the home theater system but the model number for the whole home theater system including the speakers is SC-HT900.

Panasonic SC-HT900 Home Theater System with 5-Disc DVD Changer
Very attractive system with many features. Progressive scan DVD player looks great on my projector, thanks to the high end video circuitry in the 5 Disc DVD changer. Sound is very clear and accurately reproduced though the six speakers. Movie dialogue comes through very naturally. Does a fine job at decoding Dolby Surround. Movie "bass" effects are clear and pronounced through the active subwoofer. I've tested this system in store next to an expensive Bose and the quality is more or less comparable. It is a known fact Panasonic DVD players are among the best in the business. Many more expensive DVD players(costing considerably more than this system) made by other brands use Panasonic internals for their players.
All DVD players must contain an MPEG decoder. In addition, progressive scan DVDs must contain a special device called a deinterlacer. Interlaced video frames are sent to a television in two pieces, by first drawing all of the odd lines, then the even ones. The deinterlacer essentially doubles each frame of video(producing a very defined picture) by filling in missing information. That is the true meaning of "progressive scan." This is the basis for HDTV, and be aware that your (Projector,TV,LCD) must be able to display HDTV or progressive to take advantage of this great feature. As with any other product, deinterlacers vary in quality and must be able to handle various film encodings. Panasonic uses top notch internal hardware to perform the deinterlacing(DCDi) and decoding. The results are spectacular!
Don't expect the bass to blow your ears out - no system at or near this pricepoint will. The subwoofer is powered but yet conservative (but more than other systems in its class). Don't buy this unit to play at maximum volume. System can be cranked up to loud but not extreme voulme. Sound will be more than enough for rooms This unit also makes a great system for listening to FM Radio, CD/R etc. Unit supports many types of Discs. Music seems rich and pleasing, in some cases exceeding much more expensive units.
The speaker stands will save you the cost of buying wall mounts. This system has a plethora of features that are stated in the manual. For example, there are multiple surround modes, seating placement adjustments and digital input capability. Unfortunately the owners manual is written like an engineering course lab manual - so it may take the non- technical some time to learn all of the arcane features. Also, you should purchase at least a 16 gauge spool of speaker wire - do not use the doorbell wire that is supplied with the unit.
Overall I will give this unit 5 stars, because it is priced very well with respect to its competition (Sony Dream system 990) and it exceeds that and other products in its class in terms of quality and features. On the other hand, if you desire a very loud, extreme bass systems - don't consider a home theatre in a box. Purchase a component receiver/amp with large poweful speakers. And of course, a Panasonic progressive DVD player for the best video!

Can I connect a Sony DVD Player DVP-SR90 to the Panasonic Home Theatre SC-HT75 to achieve surround sound without direct SCART connection - and how?


You can connect your Sony DVD player to your Panasonic HT using an analog RCA audio cable (white and red) for stereo sound. Connect to the AUX inputs on the HT and select AUX. Since the Sony DVD player only has SCART, you would need an adapter, scart to RCA. Like this one:

Check for compatibility. Use the red and black RCA plugs for the audio into the HT.

Your Panasonic HT does not have a digital audio input which would be required for multi-channel surround sound (Dolby Digital 5.1)

I have the Panasonnic SC-HT900/SC-HT700 and wondering if it can fully used and connected through my PC?


Well, that would depend on the audio capabilites of your PC.

Once you figure out the software controls of the PC audio you can treat the PC like any standard audio device for input or output if the compatible physical connections are there.

Low sound when turned to AUX for surround sound


remember to turn the volume up on the cable box and down on the surround sound so you will get max audio input to the surround system and then adjust using the surround sound remote! good luck
