My pioneer DVR-720 sometimes turns off (from "stand by") by itself completely and cannot be turned on again. Only if I wait for about half an hour and plug off and on all the connections (2 x SCART, 2x antenna, 1 x power supply) it will turn to "stand by" again. Any ideas what is wrong with it?
I have a solution to power it on again quickly. Unplug the power cable, short out the pins in the power socket in the back of the machine ( NOT THE POWER CABLE ) and plug the power cable back in - it should go into standby mode immediately. I think the problem is caused by a capacitor on the power supply board going faulty with age. I have not had time to open the machine to check yet, but I will do so soon.

Thank you for waiting, your problem is commonly caused of leaky filter electrolytic capacitor in the power supply section, it will affect the regulation of the supply and sometimes need a little warmp up to back from functioning. The symptom will get worst if didn't replace the capacitor. Once isolated your unit will back to normal again.
Hope it may help you.
Give a thumbs if you find it useful.
Have a nice day!

I had a similar problem with my Phillips 42 in. LCD HD TV.
Here's the problem. The Power Supply Board. I opened my TV
up(warranty was up of course) and found several bad capacitors.
Phillips and several other companies were sold capacitors that although
were highly rated failed within 5 years because of a lack of
preservatives. All sorts of electronic equipment is now being effected
due to these defective capacitors.
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.
My set is doing the same thing again. The last time I fixed this (4 years ago) it was a capacitor gone bad in the power supply for the 24v standby circuit. (C166)

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 (nikko-electronics.co.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.
