Tip

My sony 3 disc ex-change/mini hifi component system mhc-rg66 it keeps flashing...


First things first. The unit doesn't switch on.
- Is it plugged in?
- Is the fuse blown?
- Does it look like it's suffered damage?

It switches on, but won't play anything / the lights come on, but no sound.

- We'll start at connections. Is your MP3 player/ iPod/ CD player/ record deck plugged in correctly?
- Are the speakers plugged in correctly/ at all?
- Is it in protection mode - this is a pretty standard thing now, where the amplifier tries to deliver more than it's rated current (ie, into a short circuit), and it cuts out. The only way to fix this is to take it to a local hifi shop, who will reset it (there's usually a small fee involved). The unit will be fine after that.

------- There is no bass. ----------
A few causes for this, so there's a few solutions.
- The speakers are out of phase. This is where one speaker is wired normally, one is wired in reverse. The bass from each speaker is "opposite" and would cancel out. To solve this, Make sure the + on the speaker is connected to the + on the amplifier. There's usually a stripe on the cable to help you determine this.
Cause # 2
The eq settings on your ipod/ unit have been messed with.
Set all the equiliser settings to flat, then readjust them to taste.
Cause # 3 (nasty one)
You've blown a woofer. The explanation is this - the speakers have taken in too much power, the bass unit has got too hot and the glue holding the coil in place has melted. Usually, the woofer can't be physically pushed when this happens. To solve this, it's new speaker time. An alternative is to see if you can get a recone kit for said speaker, and try to fix the voicecoil yourself. This isn't recommended to those who are new to the idea.

I hope this helps the reader.

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.
