Issue with Philips home theater system

Strange thing happening with my home theater system. The red on light
is flashing rapidly, almost to the point of being completely on solid,
and when you press on the power button the indicator shows "TV" or
"Disc" or whatever, but turns off after just a few seconds. Any clue
what's going on here? Thanks in advance for any help you can provide.

Either one of the secondary-side electrolytics is failing, or one of the
secondary side rectifiers is leaky. Either way, get it sorted soon as,
because if the regulation fails because of the main rail appearing to
be low, much other damage can be done to LSIs elsewhere in the machine.

Thanks for your help. I hate to waste, but since they don't cost that
much these days, I'm thinking I'll just replace it.

Thanks again.

Well, for the sake of a few pennies worth of caps I would have thought it
was worth a go at least. Otherwise, what was the point of asking the
question on here ?

Maybe the OP was looking for some magic incantation to render or perhaps
a sprinkle of holy water to cast out the demons?

Indeed, did he think it could be fixed magically and at no cost via usenet?

No, I wasn't looking for a magic fix, but rather some ideas that I
could maybe try. I'm not an expert, so I don't even know what it
meant by trying the "caps".
Why the cynicism?

So would you rather have someone tell you to shit-can it? If you don't
know what "caps" are you have no business seeking repair advice.

Well, you could try unplugging it for a few hours, but I cannot see
this doing any good.

Caps are "capacitors". Although they're made of a variety of different
materials, the ones that are typically troublesome are known as
electrolytics. They contain a roll of thin metal foil and a moistened
paper inside. They usually look like cylindrical cans of varying
sizes.

Some overworked, cheap or improperly made capacitors fail when the
paste dries up. Sometimes such capacitors look defective (tops or
bottoms bulged out, leaking paste, etc) and sometimes they do not.

New electrolytic capacitors are cheap, and if you replace the bad ones
soon, your equipment can be brought back to life. You'll need a
soldering iron, something to desolder with and of course, some new
solder.

Why the cynicism?

I think it's because you asked in a newsgroup dedicated to the repair
of electronic devices and then expressed a total lack of interest in
fixing your equipment.

But that's just a guess... :)

Magic incantations don't work by themselves. However, when combined
with burnt offerings, they are quite effective. I would recommend the
immolation of an old PCB on the barbecue as an initial offering to the
electronics gods. Ummm.... do this outdoors.

Looking inside the box and reading the entrails is also effective. The
problem is often easily visible.
<http://www.badcaps.net>

I'm somewhat undecided on the effectiveness of water, holy or
otherwise, as a cleaning agent. While fairly useful at removing ionic
contaminants, water is completely impotent against grease, oil, slime,
goo, crud, vermin, filth, and Earl Gray tea. Detergents and solvents
are far more effective. In some cases, the traditional sprinkle is
sufficient, but for major demonic infestations, immersion followed by
a compressed air drying, will be required.
