Need Help With TV

[Alex Thomm]

I have a Philips TV model 32MF505W/17 that has no sound. Something popped and
smoked and when the sound stopped. The picture is still fine. I've taken off
the back and took off the center metal cover. Everything looks fine there.
There is another metal cover that I cannot take off without being a little
inventive. Under that cover I suspect will be the amplifier board? There
should be something visibly burned there but I can't see it with the cover in
place.

If that circuit board is fried, is it possible for me to buy a new one and
install it myself?

Are the sound line outputs also dead? If not, you can run them to a
pair of amplified speakers.

Did you connect up external speakers to this set?

No. I used the set as both cable TV and computer monitor. When using it as a
monitor, I used separate speakers that was connected to the computer.

I'm not knowlegable enough to know if the line outputs are dead or not. Is
there an easy way to find this out?

Connect a pair of computer speakers, or run them to an aux input on a
stereo.

My computer speakers have a different connection. I don't have a stereo on hand
with an aux input. Thanks for the suggestions. I'll see what I can dig up to
test this out.

Does this TV have a headphone jack? If so, try it to see if you get
sound there.

Getting a rca to stereo miniplug adapter is trivial. Any target,
walmart, radio shack will have them. Even a well stocked truck stop
will have one.

If something went pop, and magic smoke was released, there's a good chance
that you will find that the side has blown out of the audio output IC. To an
experienced engineer with appropriate desoldering equipment, and the skills
to use it, replacement of such an IC is a trivial task. However, if you
don't have those skills and equipment, which your post would suggest you
don't, you will struggle to remove the old IC from the PCB, without doing
damage to the tracking.

Unless you feel confident to do this, then I would go along with what others
have said, and try running the audio line outs through an external
amplifier, or take the TV to a reputable repair shop. If you do decide to
pursue finding the problem, *please* be VERY careful . TV sets use
switchmode power supplies, and these are VERY dangerous - actually
potentially lethal ... :-(

Well, certainly there are other things that I would rather mess about inside,
but right now I'm concerned with the TV.

If something went pop, and magic smoke was released, there's a good chance
that you will find that the side has blown out of the audio output IC.

I think that's what I already suggested in layman's terms.

You did not suggest in your original post, in layman's terms or any other,
that you knew it was likely to be the audio IC that you were looking for, or
in exactly what way it would be damaged. You only said that you thought you
would be looking for "something visibly burned". The reason that I told you
that it was likely to be the audio IC, and that it may well have the side
blown off, is that if you don't know what you are looking for, which clearly
you don't, an IC damaged in such a way may not be immediately apparent.

To an experienced engineer with appropriate desoldering equipment,
and the skills to use it, replacement of such an IC is a trivial task.
However,
if you don't have those skills and equipment, which your post
would suggest you don't, you will struggle to remove the old IC from
the PCB, without doing damage to the tracking.

What is tracking?

I'm afraid that, much as I like to encourage people in the field of
electronic repair, in this case I have to agree with others, that perhaps
you should not be attempting to repair a TV set.

Without even the knowledge of what PCB tracking is (in this particular
context, it refers to the copper "tracks" which interconnect items on the
pcb), then I feel that taking on this repair, is beyond your abilities to do
safely and reliably.

Unless you feel confident to do this,

I am plenty confident. What do you suggest?

If you want to go one stage further, follow the wires back from the TV's
internal loudspeakers. They will (probably) land on the main PCB very near
to the audio IC, although that is not guaranteed to be the case, either. It
will likely be a flat plastic device with around 12 to 20 'staggered' pins
on it, and be bolted to a heatsink. Be aware, though, that there could be
other ICs in there as well, which match the same general description ...

OK, I followed the wires back to the largest PCB. There are no heat sinks
there. I think the best thing for me to do is post a photo of the circuit
boards, but that will have to wait because my computer got infected with Anti
Virus Live. What a mess! I can't do anything. It blocks everything that I try
to do, and it still infects when I boot in safe mode. I'm typing this on my
laptop and I have no way to transfer photos to it easily.

I have a Philips TV model 32MF505W/17

Actually, it's a 32MF605W/17

Are the sound line outputs also dead? If not, you can run them to a
pair of amplified speakers.

I'm not knowlegable enough to know if the line outputs are dead or not. Is
there an easy way to find this out?

And you think you can fix it?

Trying to fix something is better than slingin insults, which isn't all that
productive, yeah?
