HTS8100 - Low sound volume... anyone else with this problem?
Maybe if I start a new thread, we can get some more activity around this topic!
My HTS8100 has worked almost flawlessly (occasional problem with sticky sliding door), but last week the sound volume started to go to a VERY low setting. If I turned the system off a few times it would come back. But the last 4 days it has stayed low. I can hear it, and it I set it to max it gets a bit louder but not loud enough to be usable.
I have tested it with different devices and different outputs (HDMI1,2,4/Optical and RGB), so seems to be a problem with the entire system.
Anyone else find a fix, short of a do it yourself repair like the person who I have quoted below? Does a Philips Moderator have any information about this or advice for an "out of warranty" fix?

I read over this post when I first started searching for a resolution for My Phillips equipment. Understand that there are alot of politics and lawyers involved in making decisions at a corporation...
However, I am usually a one to two post guy to those who REALLY need the help. Being that there is NO solution that I could find on the internet, I figured I'd go ahead and see if this would resolves someone's issue without costing them anymore in repair or heart ache! lol
Here is how I repaired my problem...no sound. I cannot vouch for the door jams....
My problem was found within the sub woofer. This is where the power supply is located. Best i can tell without schematics is that there is a primary and secondary power unit contained within the power supply. One powers the the amplifier board and the other powers the sound bar.
Do this at your own risk!
Remove the board (further most lower board contained in the subwoofer, watch out because there are some tricky screws to remove) and you will notice that there are two IDENTICAL electrolyte capacitors ( if you don't know what one looks like, google it) on ONE the side of the board. Mine are marked> 200V 330uf 85C. Without going into the circuitry of how I discovered that the ONE was faulty and the OTHER was on its way faulty, replace them. Don't attempt to replace them with a different value as the original as failure is sure to occur. Spend the extra money and get the exact voltage, micro-farad and most importantly, temperature.... I can go on and on about how they are applied within the circuitry, I have a feeling that no one would really care about it! Just know that the circuitry is set to rely on the primary capacitor , which will eventually lead to another failure...If this is your issue, you will see that there is wear around the plastic of one of the capacitors. My unit has been running for a few days now, so be confident that if, indeed, yours has this same issue, this will fix it.
Good luck! And I hope it resolves your issue...
