Philips 19pfl5422d/27 same sound problem

I have the same problem with these tvs. I actually inherited 4 of them that are having the exact same problem, bought about a year and a half ago. There were approx. 25 with the same issue though! I cannot believe that is a coincidence, so I figure there must be some way to fix it. The sound comes on with a large amount of static, and then sometimes no sound comes out for minutes at a time. If I go into the sound options and turn all the settings all the way down (under the Personal settings option), it is a little better, until the sound goes off again. I have soldered boards for computers before, and I believe I could fix it myself. I don't want to pay for repair, and since I have a few of them and I got them free, I'm not losing any money - but I hate to throw them away if they can be fixed!!!

Any help would be much appreciated.

    Thank you so much dsacco for the advice. I'm taking a look for the service manual, but I'm wondering if anyone has reported this specific issue before, because it is evidently a flaw in the manufacturing. If so, someone might be able to point out exactly where to look and on which board.

This should be a piece of cake for you.
The best thing you need is a Service Manual for the TV. Costs about less than $20 over the internet. It will have schematics, diagrams and part number list for the TV. It's the best thing to use for diagnosing the problem on the audio board. It maybe something simple like a conductive adhesive material for a heat-sink that spread to other contacts on the board.

Phillips 19" flat screen

OK, I had the same problem and I fix it 100%.
The power board is ok, the lamps are ok, don't waste time there.
Just open the TV, remove the shield of the mainboard, and in the side where are the wires from the power board, there are many capacitors, check them, in my case 4 were "fat", exploded.
I had to change 9 to make shure, and that's all !!!

I wna the manual for 19PFL5422D philips 19 inch

Sorry, but you wont find service manuals for LCD's. You may find a flow chart but that's about it. We,as technicians don't need manuals for these anyway. If you want to let me help, just send me an e-mail with your problem or just re-post here.

Philips flat screen TV MODEL ID 19PFL5422D/27

I bought the television less than a year ago, so I called Philips Magnavox and they asked for the serial and model numbers. Next thing I know they asked for my name and address and Philips is sending a brand new television to replace it !!! The new one should arrive in about ten days. How's that for service? I'm very happy that I bought Philips and I will do so again. So don't forget to keep all the paper work that comes with your new televisions,especially Model and Serial numbers ! Thanks for asking , Debbie Hoffman
