Hello,

there are so many reasons why your TV won't bring out sound. You need to troubleshoot first, in order to get to the root of the problem, before a solution can be proffered.

First, connect a DVD player to the TV, observe if there is going to be sound. If there is still no sound after connecting the DVD player to the TV, proceed to the next step. "The reason why I asked you to connect a DVD player to the TV is to confirm if the problem is simply not from the audio cord connected to the TV."

Second, get an headset, connect it to the earphone jack of the TV and observe if there is going to be sound. If there is no sound, then it is glaring now that your TV is having a defective sound card/IC that's why it is not bring out any sound. (Note that connecting an headset to your TV is optional because not all TV's has a space for headset). "The reason why I asked you to connect an headset to the TV is to also confirm if problem is not from the TV speaker. Though TV speaker problems are rare but sometimes, the TV speaker might be defective or the speaker wires may have loosed contact or cut into two, due to one reason or the other. But if the headset doesn't bring out any sound from the TV, then it is not so."

If none of the above seems not to be the cause of the problem, then the above troubleshooting has confirmed that the TV has got a defective sound card/ic. The sound IC/card of the TV has to be replaced for the TV to bring out sound again.

To be honest with you, replacing or fixing the sound card/ic of your TV requires the ability or experience to do so.

Now, if you are convinced you can fix or replace this yourself, please reply so that i can help you further. And make sure you troubleshoot first, before getting back to me.

Regards.

    Hello Walesarumi.

    I recently got a Philips 42PF9966/12 TV that was about to get discarded. The picture is wonderful but there's no sound whatsoever, neither from speakers, headphones nor RCA output (surround system).

    Would you perhaps know where to find a sound card that works with this unit? I've done some soldering before and am good with installing cards on my PC, so I might give it a try.

    Thanks.

    /Matt A

NO POWER ON PHILIPS 42PF9966/37


I had the same problem with a philips 42FD9932 and fixed with a great online tutorial. Just replace 3 capacitors available at Radioshack onthe the board. 2662, 2663, 2664 1 is a 1000uf the others are 100uf. Max Volts need to be over 25. It worked great, check http://dynamicorange.com/2008/06/25/fixing-a-plasma-tv/

We bought a Philips TV (model : 42PF9966/79) three years ago. Intermittently we are getting a thin black horizontal line through the middle of the screen. What is causing this?


The model number you listed is bad. I think the last 2 numbers should be 37. But it sounds like a plasma tv. In that case the problem can be a bad connection from the driver board to the panel.
Take off the back of the set and reseat ALL of the ribbon cables on the far left and far right sides of the set. If this does not fix the problem, the panel is bad. This is not worth fixing. Buy a new tv.
