Philips 27PT643R37A switches on and inmediatelly off
I have the following problem: This TV set has been working with no issues since 2002. Suddenly, I tried to turn it on but the only thing that is happening is the green LED goes ON and inmediatelly off. You can hear the double "click" coming from the relay. (1st to turn it on, then off). It's seems to me like a leacking capacitor. In the sorroundings of the relay there are a couple but I don't see anything burnt.or suspicious. I did not spend time looking up the schematics.

More than likely it's activating the protection circuitry. Most of the time televisions won't give you a sign of trouble until something actually breaks. One day they work and the next they might not. There could be a problem in the power supply or the scan section which are both internal that would inhibit operation to prevent your set from overheating and causing a problem external to the TV like a fire. If your set is over 10 years old, replace it. If it's quite new but out of warranty then get an estimate at a reliable electronics repair store.
they have to be downloaded onto a flash drive from philips website.. there is a usb port on that model. make sure that the tv is off before plugging the flash drive into the tv. then turn the set on and follow the onscreen prompts..this is the same thing you are going to do that a service tech would charge you 200 bucks to do..make sure you download from philips and not a so called fake..good luck by the way i am a certified philips tach..
I don't know about this particular philips chassis but I've got a phillips tp3281 with a #32d700-7570 chassis with the same problem: apparently common with philips sets. I opened mine up and discovered the burnt capacitor that others have reported, replaced this as recommended with a higher rated one. In many cases this is apparently ALL that is required to fix the prblm (a 50 cent part)unless other components are also damaged which appears to be the case with mine. This repair is about $150 here locally at a shop which I didn't want to put into a relatively old set. Have you opened up your set yet? Do a Google search on your set and you might find that others have had the same problem and a simple fix could be possible.

I did not answer the original question you posed but the SAP is the acronym for Separate Audio Program and is used to provide spanish for instance on a show which is broadcast in both english and spanish. The problem is not all stations have audio on the SAP. If your audio processor is set to SAP and you switch to a channel which has nothing on SAP you loose audio. I'm guessing someone suggested this prior to this post. If you checked your TV and it is not on SAP that eliminates that. I would look at the audio circuit for problems. Either no power to the audion circuit, bad solder joints, blown output IC or possibly a blown speaker. I know the last one is remote but it does happen and it never hurts to check the simple problems first. Besides you aren't embarrassed later when you find out it was something simple. If you are going to check these issues out remember safety. Good luck.
