I can't seem to get the volume up button to respond

Are you pressing the fn key at the same time? These are FunctioN buttons and work in conjunction with the fn key.

consult the owner manual or call Samsung---this set likely has a lockout feature that locks both the remote and the keyboard out.

You might also want to research this by taking the model number and Google key words "remote lockout" etc.

If there is any Fn key dedicated to speaker to mute or unmute, then you can use than button. There will be one hard button on the keypad. This exists for each laptop.

Try powercycling phone; turning it off and removing battery from the back and leaving it off for about 1-2 mins. Then re-start phone. if the same thing happens, try doing a master reset on the phone instead. However, if it's still doing the same thing... might as well have it checked to verify if the phone needed to be repaired.

1. Go to "Adjust Audio Properties". In Windows XP, you can get here by right clicking on speaker icon in system try.
2. Click on speaker volume push button.
3. Increase the left volume to maximum.
4. Now, play some music or some audio content.
5. Then reset L and R speakers default (L and R speakers will be at 50%).
6. Now, both speakers will work fine.

FDD2 used to balancing sound between two speakers was probably malfunctioning and it was reset by above exercise.

try this - Master volume controls for the HK-695 speakers are located on the top of the right satellite speaker.

Have you set the Power IC to Off? Here is a link to the User Manual: http://www.alpine-electronics.co.uk/index.php?id=915&L=&manualsearch=CDE-9850Ri

Press Menu to select Setup, then Mode, then Rewd or Ffwd to move Left or Right to Power IC, then use the volume control to select Power IC On.
Hope this works
