Volume changes on its own.

bagaimana caranya buka sandi hp expressmusic

Very simple. It is not a defective unit. Simply a matter of volume attenuation, hold the "function" and "grove"keys for aprox 5 seconds until a message saying vac off appears. Problem solved. Resets itself eveytime the unit is turned off .
enjoy!!!

Hi:
Most cable or satelite boxs have their own volume controls try using the boxs remote to change vol levels to see it this solves your problem.

Main system control memory IC fault. This is a very small IC; have 8 solder terminals, and can be located very near to the main system control-chroma IC. Check and replace it. Be sure to replace it with the same number printed on it; in all respect. Otherwise, it won't go. http://electronicshelponline.blogspot.com/ Before replacing it, try a reset to this set, and then check.
There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

Many times there is a volume switch on the actual handset itself. Most commonly on the left side of vtech devices. there are three different volume levels. By pressing up on the button you should be able to turn the volume up until it has an audible tone confirming volume change. Handset should ring with incoming call when audible tone is heard by pressing up on volume button.

Have you checked whether there is a volume limit on the nano. Go to settings then playback and then volume limit. From there you can adjust the maximum volume you can have. Hope this helps.

My Yahoo YHT-400 does something similar, only it won't do it right away, it has to start getting hot first, then if I have the volume set at 25 or higher, it will slowly start turning itself up louder until it either maxes out, or I intervene. Either way, it's really annoying, even though I'm only using it as an amplifier for my computer. I just figured it was doing it where it's second-hand and had tons of dust inside caked in and around the fans until I cleaned it out. But when on AUX/TV, one would think the Bit Rate Transfer gauge would remain at 00, but it jumps up and down constantly, whether there's any audio being put through it or not.

I also have the same problem, it is really annoying... anyone have any ideas.... please help!!

Hi sounds like you have the audio out from the cd changer connected to the RCA/Phono out of the radio. double check that the output from the CD changer is going into the correct phono/rca connector regards Mark www.carradiospares.co.uk
