Start with the simple things first, hunt round for fuses near where the mains goes in. Keep on the lookout for anything that looks burned or broken. If there's no power to anything it will be something in the power supply section.

My sony mhc-rv777d is not working when i on my sony within 4or 5 sec it off automatically so i need a solution


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.

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.

Sony Mini Hi-Fi Component System (MHC-RG660)


I understand the problem. It should be the relay which is not responding, technically not able to connect the system power supply, you will have to replace the relay. The STK chip should be working fine.
