to rectify this problem you will have to replace few capacitors in the power supply circuit. Caps to replace are C16, C17, C21, C26, C27, C32, C47. Be very careful with two screws located under the heat sink. DO NOT MIX THEM WITH THE REST OF THE SCREWS.
Hey I have a DVR50 which appears to have given up the ghost. Its probably beyond economical repair but I'm gonna try the service centre later today. If you have any trouble getting a new remote I'll gladly send you mine if I have to scrap the DVR50. I'd rather someone get something out of it. Just pay the postage and thats fine. email@example.com
I have the same frozen problem vith Jamo DRV-50. But I found this:
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.
