This is probably the wrong ng to put this in but i couldn't find a more
suited one. I have a Wide Screen Philips TV Model No: 32PW6332/05 i was watching something when the TV just stopped working and now when i turn it on i get no picture and it just keeps making a strange noise from the back like twerp twerp twerp twerp its not a high pitch sound but more like the sound the TV makes just before it comes on. I can solder and have have some experience of electrics so if anyone knows how to fix this TV i would love to here from you. Kind Regards Simon |

For the first thing, it's a Philips. I have an absolute hatred for anything
Philips, bad quality and poor soldering /design. Rant over, the most likely culprit is the line output transistor has gone short circuit or leaky. So, take off the back and resolder all of the pins on the line transformer. Grab a multimeter and do a diode check on the line output transistor. If all 3 pins read almost dead short then it's fried, probably 95% of the time you can just change it and the set will be fixed, although in that nice rare occasion, it will work for a matter of hours or days and then die again, pray it doesn't. If the line TRX is not short circuit, then the transformer may have died or a rectifier diode from it may also be short circuited. The twerp sound you are referring to is called hicupping, more common in older Philips TV, ie KL9A, KL9A2, which would often be either S/C line TRX or faulty high voltage pack or tripler. Paul |

Ok thanks for all the info, i think I'll get the TV man in to look at it.
lol I didn't know anything about Philips but i will keep it in mind what you say about them, I normally get Panasonic they seem to go on and on. Thanks again Si "loedown" wrote in message ...
