I know this is not the answer that you want to hear, but: That television is not capable of delivering audio output to all 5 speakers - it is a stereo-only TV, which only delivers 2 channels.

Furthermore, that Coby DVD-937 only has Digital Audio outputs rather than inputs, which is very strange and complicates our problem immensely. You will get 5-channels with DVD or radio play, but getting 5 channels for TV is not possible without additional equipment.

The manual for the Coby mentions a "Digital Decoder Amplifier," which would work. You would connect a digital audio cable from the area marked "Coaxial" on the back of the Coby to a digital audio IN on the back of an external amplifier. You would connect the speakers to this amplifier, instead of directly to the back of the Coby. Then you would need a cable or satellite box with digital audio outs (fairly common nowadays) to another digital audio IN on the back of the amplifier. The cable or sat box you may have already, but you may need to purchase such a "Digital Decoder Amplifier" or other digital amplifier with appropriate speaker wires and 2 digital audio input slots (not to mention two digital audio cables). Fairly complex. Possibly expensive.

Need to find out a part # for my philips 52PFL7403/f7 for the ir sensor


Join Date: Nov 2011 I have a Philips 47PFL3603D/F7 with the same problem. It was the IR sensor board causing the problem. You can search online to find the board, which almost everyone will most likely not have in stock, and cant be ordered. The part you need is this: 313926859181 IR Remote Sensor.

Models it will fit are as follows: Substitute Parts 313926859182

If you can find the board, great! A replacement board costs about $12.00. If you can't... we'll there is something you can try ; )

Either way, if you know it's the board, what's the harm in trying?

Remove the back from the TV. You can actually leave it on your stand to do this if you can spin it around to gain access to the back of it. Be sure to unplug everything first!!!

Looking at the back of the tv, the board will be located in the lower left side by the speaker. It will have 2 cables attached to it. Remove them, and take out the screw or two that holds it in place. There will be a plastic tab that keeps it in place also.

Take your fingernail and bend the tab back, and the board should come free. After that you should be holding the board in your hands. The side of the board with the connectors on it is the side you want to manipulate. There will be a tiny surface mounted capacitor beside one of the wire connection sockets. Take a utility knife and scrape it off/ you could use a soldering iron but it should come off very easy with a knife.

Plug it back in, and give it a try! If it works... great! If not, find a replacement board, and try that.

Hope it helps someone!!!! quote.gif

Is it only one time? If it is out of the speakers this could be going from analog audio to digital audio. It could also just be the cabinet expanding and contracting.
