I have been using the Sony DB 780 for 3 years with much satisfaction. As a result of moving houses the amp/receiver remained idle for one and a half years. Few days ago I wanted to put it back in place and realise that:
1. front speakers no output
2. sub woofer no output
3. rear speakers plays faintly
4. center speaker output excellent.
Could someone tell me what the problem may be and what could be done? Best regards.

HI YES YOURE GOING TO NEED A FEW RCA CABLES u. can use video 1 to plug youre tv in and use video 2 to plug in youre vcr ::::::::::connect youre speakers up to the red and black speaker terminals marked L & R..good luck
.. or read the manual about setup and getting multichannel audio from 2-channel sources. Calibration and Selecting a Sound Field.
Distance is linear spatial separation of two points. dB is audibility, sound pressure level, volume. The distance setting affects how the various channels are delayed to arrive at the primary listening position at the appropriate time to provide a plausible sound field. Simply making one or more speakers louder or softer will not affect the spatiality of it.
I went through the amp/receiver and used small star washers on all the grounding screws I could find including the one securing the transformer, cleaned dust off all circuit boards, checked output transistors and fuses, all OK.
Re Assembled unit and it worked OK.
I will buy a fan and fan it to avoid sourcing heatsinks for the previusly suggested IC's.
Thanks for the technical help, sure solved my problem.
