Question about Home Theater Systems
I have a DS 1233 surround sound system that works fine when it starts up but after several minutes the system reverts to stereo only. Changing volume up or down by on notch gets the surrond back on.
This happens on all inputs. Any advice most welcome as it would be a waste to have to change 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.

Hide the remote from the set for awhile and see if some sanity returns. If that's the case, service or replace the remote. (Check the batteries first...accordianman

I belive that you have a lot of dust how is gatherd behind the system in the amplifier and it is preventing it to cool down you need to blow it clean and make sure that you keep the system gets cool air
if the temp in the amplifier gets to high it shut down the system instand of burning it very clever solution from the manufacturer
you have a very good system good luck

Hi....I haven't hooked mine to the TV yet.....building my cabinet now....but I did hook up the components to make sure they worked and just didnt include a TV on it. My S-Air wireless linked up the first time I tried it....I will say this though, the little wireless transceivers blocks you have to plug into the DVD player and the S-Air do not go in like you would think. They actually look like they are upside down when you get them in, and the must snap in very securely. Make sure they dont just LOOK like they are plugged in. Also, dont get em to far away through too many walls, Try linking it sitting right close to the DVD. Also remember the S-Air remote has its own volume control as well as other controls....
I know I wasnt much help but I just got mine and I will be back with more after I try the surround sound on the TV.

hello it sound like the output ic may be in trouble you may have just dry joint on the ic which just resolder it . or there could be a capacitor leaking or they may have swelled up in which you will have to replace. it's best to do some visual checks first i'e look for any burnt parts any capacitor with bulging tops
