Jamo dvr 50 buzzing/crackle from speakers after repair

hi G,

You can replace DVD unit with one est?ndar for pc.

The only thing you must do is remove the front of the tray.

Try to trace the fault systematically from one end of the system to another, starting with something that you know is working

1. Start by checking your sound source (cd player or whatever) is working by connecting it to another amplifier or computer.
2. Check the connecting cable is working from the sound source to the amp and is not shorted out.
3. Make sure your loud speakers actually work (briefly shorting a 1.5 volt AAA battery across the speaker terminals should produce a crackling sound without doing any damage)
4. Check loudspeaker cables are properly connected to output connectors and are making a good contact.
5. Try connecting something like your computer speakers (or use the microphone in jack on the computer itself) to the line output socket of the Jamo. If you can get some sound this way it would suggest that the internal output overload protection fuse may have blown. You will need to open the case to access this. NOTE if your JAMO is still in warranty take to authorised repairer otherwise you may invalidate your warranty.

Might have got something to do with the powersuply, tjeck http://www.fixya.com/support/t3738600-receiver_doesnt_start . I am about to give it a go, I have a dvr 50, and my friend has got one aswell, and it is my belives the powersuply is creating all the noise, and your problem will probably only become worse.

you have a defective power supply.there will be caps on power supply that will need to be changed,change the caps that looks like the tops are pushed out.unit should then work.

Hi I have jamo Dvr50 system and it has been frozen since yesterday. I have power down few times but nothing is happening. It comes on and panel lights up but that is all.

It is probably the powersuply, tjeck http://www.fixya.com/support/t3738600-receiver_doesnt_start

I have the same frozen problem vith Jamo DRV-50.
But I found this:

www.leifline.com/reptips/DVD_DVD-VIDEO/DVD.htm 

Its a swedish site for electronic repearments, Jamo DVR-50 have problems with heat also and capacitors in the power suply unit goes burned. So the instructions are:

1.Simptoms:Various strange error

2.Solution: Replace the capacitors in the power supply, especially C30 470μF/ 10V, C31 2200μF/ 10V and C16 1000μF/ 10V.

My service guy already told me that some electrical parts in the power supply unit are burned, he replace them and succeded to powerOn the unit but still jamo have problems staying powered on and now im going to tell him to replace those capacitors C30, C31 and C16, and i hope this will work.
