Question about Philips HTS3440/37 System

1 Answer

Intermittent Sound I have an HTS3440\37 System. when watching movies, e.g. action, the volume cuts-out when there is a drastic change in the scene. for arguments sake, I was watching Transformers, and the volume cuts-out whenever there is a loud boom or crash. By pressing the mute button once and then again, the volume comes back on until the next loud sound. I tried cleaning the lens, rearranging the order of the speakers, i.e. front to front right..switched and rear left to rear right..switched. That didn't work, as recommended by Phillips Cust. Supp. Has anyone had this problem before? If so, what did you do to fix it?   Thank You,     James C.

    This was the same thing mine would do. It didn't happen often, but when it did i just restarted the system and it was back to normal. this last time it happened, my center channel speaker stopped working, and now i can't get it to play no matter what.

    I have the same problem to, i have tried just about everything. It norma-Iy does it at any loud noise in movies and seems to get more and more frequent. What I think that it is doing is going into a protection mode kind of like a car stereo amp does. I might open it up and see what i can find! I have had it for about 1.5 years and has done it since i've gotten it. Gl to you.

    After looking at the sub-woofer, I discovered that my 2yr old decided to stick a silver-dime in between the fan blades on the back of the woofer. I took a pair of tweezers and got the dime out. I haven't had an problems since removing it. I want to say that once the woofer would get hot, the fan was unable to cool it down enough to handle the change in volume. Sorry that I can't assist you guys with info for trouble shooting. I'm just glad that I didn't have to buy a new system.

    After taking apart my system I didn't find any noticable problems. I did how ever clean out the dust and tried pointing a fan at it. It still does cut out from loud noises and it does it even when it is cool. So the fan not cooling doesn't really fit why mine does this. I have written the Phillips company and haven't recieved anything from them in reguards as to why it does this. I know a few people with the same system as me and their system does just fine. We may have just gotten a defective product. I have heard from a few people that things that are bought from Walmart or Target (electronic wise) are a lower grade then something bought from Frys, Best Buy, or any place similar. Not to sure how true this is, however I did buy mine from Walmart for around $200. But you do get what you pay for. There are far better systems out there and I may try my luck with one maybe a Bose.

I was having this same problem. I realized that the fan inside was not running so I placed a small fan over the vent in the back of the sub unit. I tried this out and it worked. I then replaced the internal fan with one i bought at radio shack for a computer and have had no problems since. Hope this helps.

Clearly, it thinks you're overdriving it.

Blinking Power Indicator every 2 seconds means the internal temperature is high. (Page 76 of the manual)

Every half-second - speaker impedance too low.

Consider the load presented by the speakers and what their minimum impedance might be.

Check for loose speaker wires.

The full screen shots are the actions scenes that were filmed in IMAX... there's nothing wrong with your player or disc!

Volume Control

I had the same issue, there is a Late night mode on the remote that minimizes the volume of a loud scene so you don't have the constantly adjust the volume. Works great if you are trying to watch a movie while others are trying to sleep.

Philips 27PS55S/121 sound level decreases

Yes, the dynamic range on DVD's is enough to cause the high and low passages to be somewhat annoying but, sounds more like a movie theater. This kind of dynamic range showed up first on Beta HiFi and VHS HiFi VCR's because of thier range as well. If there is a feature in your audio menus on your TV such as "audio expansion, SRS, Wide mode, etc." turn it off and let the audio be processed without expansion of any kind as that will amplify your dynamic range alot more. The lock up issue could be something Philips is aware about and if under warranty contact them. Otherwise not much you can do except manke sure the voltage going to the TV is failry stable between 110 volts and 120 volts. Sometimes dramatic drops and or increases can cause lock up or confusion to the microprocessor in the TV.
