Loses power after timer recording

After my Pioneer records on timer recorder it turns itself off (which it should do) but loses all power to it (which it shouldn't do). I then turn it off and after 30 mins or so it comes back on. The time for recovery is becoming increasingly longer. I have taken the player in to be repaired they have changed some parts. Whenever the Pioneer is in the workshop this problem does not happen. The repairman says he has spoken to Pioneer but has no clues. Can you please help? Cheers Saturn

Re: Loses power after timer recording

Hi Saturn et al,
I had similar issues with my Pioneer DVR-520H. It completely went off for quite a while when it should be going to standby after a timer session. At the start it would come good after a few days. Eventually it went off altogether and nothing would bring it back.
With my father-in-law being an electronics person we investigated with the help of the service manual which I found on the net. The finger was duly pointed at the power IC (MR2920) on the power supply board (Pioneer will sell only the complete board). I ordered the IC from the UK ( GBP8.99 which was the only place I could find it online and soldered it in myself (easy, if you can solder).
All fixed and working again.
Hope this helps.

Make sure you have the right date and time set. You cannot set a timer program until you have the correct time and date set. Let me know if that helps.

Won't record on blank disc.

Bulk disc that comes in cylinder case are some time faulty and loses quality because they packed on each other. The lens of the disc are sensitive so if disc is scratch or dirty will get error message "no read". Turn the unit off then unplug ac power cord for more than two minutes then reconnect and try disc again, if issue still exist purchase disc that comes in individual case.

DVR633H timer recording screen inaccessible

I had the same problem. Contacted Pioneer tech support, they had me send the machine in even though it was out of warranty; apparently a hard drive problem that they were researching. They sent it back with HDD replaced, worked again.

Recording Length Not As Indicated

Hi. Yeah, RCA soutions are worthless. What happens is that the hard disk loses recording time while in use. Like a hard disk losing clusters on a computer and making them unusable. To get that recording time back, you will need to reset the unit. To do this, go to the main menu, press and hold the play and open buttons on the front pannel for about 7 seconds. This will reformat your hard disk. Keep in mind that reformating will erase all data. I have looked up and down for some type of firmware/software update and RCA support told me to disconnect the the power button 10 times and connect again!!???!?!? How silly. Hope this helps :)

Hi, Have just purchased Samsung DVD HDD recorder (DVD-SH855). Everything works great except the timer recording. When i schedule a recording, the system wont start recording. The recording light flashes...

I had the same issue. It turns out that the recorder has to be switched off otherwise it won't record. The unit will power itself on at the scheduled time and record your program. It doesn't make any sense to me why this would be a requirement but it solved the problem for me.

Dvd recorder loss of power

It could be a bad solder connection in the power supply that opens up after warming up (you may be able to tap on the unit to get it to come and go) or you could have a capacitor that is drifting out of tolerance or some semiconductor device that is becoming leaky. It may take a repair shop to figure it out for you.
