Question about Televison & Video
Unplug all speakers rewire the speakers making sure not to cross anything check all wires for shorts (cat bites etc) Make sure that only 8 ohms (one speaker ) is on each wire or the ohms that are specified on the amp. In electronics 2 eight ohm speakers in parallel becomes 4 ohms total and will put the amp into protection mode. watch for stranded wire pieces crossing to the other wire. If it still has problems it may need to have the amplifier transistors/ics replaced. While the cabinet is open look for electrolytic capacitors that are bulged or split and replace them.

SOURCE: Toshiba SD V393SU2: No
In that case the problem is hardware - a part inside the unit has failed. To find out which part you must open the unit and start testing: check the integrity of the power cable; check that the power source gets the power, check that the rectifier on the power source works, check that the outputs of the power sources are active and what voltage is on that and finally check that the power source generates the stand-by voltage and can be activated manually.
For all of this you need a voltmeter and at least a basic experience in electronics - to know where to look and how to interpret the results. If you don't have the latter then its time to take it to someone who has it.

Your first step is to find out which phone system you have. Your phone can connect to several different Toshiba phone systems and knowing the part number of the phone does not narrow it down any.
Also, if you are looking to change voice mail features like mailboxes, recordings, etc.. you may also need to know which model voice mail you have and find a completely separate manual for that.
