Use a capacitor tester with the proper range of farads. Some electric multymeters include a capacitance, or capacitor test for farads value. This test tests not for capacitor value but for operation. Connect an ohm meter and the reading should jump before gradually settling to zero ohms. Reverse the leads and again jumps before settling down. Preferably with analog meter. Digital meter still works. I've also tested capacitors by connecting it across AC voltage and reading the amperes. Then find the resistance of the capacitor with use of math formula R/EI, then use the Xc formula I don't recall now, something like C = 1/ (2pi f Xc). For DC capacitors does not apply but to use a meter.
Most common problem is cable connection. Wiggle each lead, positive, negative in turn at amp. while playing. I assume you have checked that you haven't inadvertently muted the system.
if it receives faxes fine then its
likely the ccd reader input is disconnected . broken lead.
the sensor is above the slot where you insert the to be scanned sheet.
you'll have to open the case cover to find out.
Being a 500W amplifier, you need to connect speakers with 300W each. The correct method to connect speakers is red terminal of speaker should be connected to red terminal of amplifier & black to black. The left side to left side speaker & right to right speaker. There may be main & remote terminals. Main speakers are the speakers at local place of the amplifier & remote for remotely placed speakers. I do have Technics SU-V85A which is somewhat similar. Enjoy! A nice piece to listen.
that sounds like an internal connection problem, try getting inside the unit to where the internal wiring is connected, if you have signal coming through well thats a big plus, see if there are any loose wires or if the internal connection is damaged, would probably pay to replace the complete terminal, should be able to pick up XLR connections fairly easily from any electronic spare part dealer, trouble with this type of gear is that the connector is continually being used, so over time they do wear out or suffer damage

Defective Board (possibility) SC, SU, SD, P board (SC,SU,SD>D,P). Connect the connectors SC2(*2), and SC20 to the SC board. Remove the SU board. Turn the TV on. Does the TV power up and stay on IF YES REPLACED SU BOARD IF ON
Install
the SU board and
Remove the SD board. Turn the TV on. Does
it power up
and stay on? IF YES REPLACED SD BOARD
connect your media source(dvd-cd player)to equalizer in-connect equalizer out to amplifier line in-or aux in-connect amplifier out to your loudspeaker.
