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

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.

Why do I get OPC error when trying to record on aCDRW ON a philips cdr 785

Common issue. The lasers/transports in these are terribly unreliable.
More of these hit repair stores and skips than pints of beer down a football thugs throat.
cut your time and loses and invest in one from any brand other than Philips. pioneer and Yamaha make exceedingly good CD-R recorders for the home user. Hhb, marantz, fostex for the pro market

I have a Techview [email protected] Model 3036. Records during daylight hours but loses video recording at night?. Any ideas on how to enable the infrared recording at night? Marilyn

If you have IR capability make sure you have power to the camera as well as a video feed. There should be a tail at the camera that supports the power and a plug in for the other side.

Set vcr to record after timer is set

You need to turn off the Timer and then add your new program to the schedule. Then turn the Timer back on (power off).
On most VCRs, the Timer is enabled by turning off the unit. Thus turning it on will work (as long as a program isn't currently being recorded). If a program is currently being recorded, press Stop to interrupt the programmed recording. Then add your new program - that doesn't conflict with other programmed recording or exceed the number of available timed recordings for the unit. Then turn off the unit.

At least one VCR I owned was a bit trickier. You had to press the Timer button on the remote instead of the power button.

I 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.

MyFi loses proper index to recorded music

Sometimes this will fix itself if you take the battery out. Otherwise, the best way seems to be to empty the memory, and start all over, recording on a blank slate. These are really pretty awful machines, with endless problems.

The on/off switch on mine just broke, and I say "good riddance."
