Hi,
MHC-RV777D shuts off itself because of protection mode that is activated to avoid further damage due to defective amplifier output IC in unit.
You need to check/ replace output amplifier IC to solve this issue, if you are not familiar with electronics stuff repair then local repair shop will do this job for you.
Hope these info will help you.
Let me know if you have additional question.
Thanks.

If your system was not used for a long time , then there are more possibilities for failure of belt . I have also faced the same problem. Better get the belts replaced in SONY Service Centres

I just want to know that how can i connect my sony mhc rv777d to my pc


Input to the the PC or OUTPUT from it? It matters.

To use the Sony as the speakers for the PC, treat the PC as you would any other audio source. You can use the headphone out or the green speaker out or any available digital output if you have one. Just make sure you adjust your PC's sound controls to enable them and turn up the volume.

Not getting high depth of bass sony MHC-RV777d


I wouldn't expect huge bass from those little speakers. Somewhere on there, there's an equiliser, where you 'll probably be able to turn the bass up and down. See if that works. If not, new speakers may help.

How to incrise the bass of sony MHC-RV777d


Is it possible that the speakers are out of phase, where one speaker is moving out, the other is moving in, resulting in zero bass?

Other than checking wires, making sure + on amp is linked to + on speaker, try changing the eq settings, or sit them next to a wall - walls help bass a lot.

It seems that you have get the color system setting of your Tv wrong. Sony uses the Pal(it's a format for the transmission of signals) color system , so check into your TV's color system settings and change it to pal , if that doesnt work then change it to Ntsc.
