My power supply has burned out on my Pioneer DVR-225. I've taken off the cover to look at the power supply board. It looks like one of the capacitors popped.
The fuse is still in tact.
I'm trying to find a schematic for the power supply (VWR 1378) so that I can purchase the correct part?
Is there any way that I can verify that it is the capacitor that failed? I can't smell anything on it...but it is bulged on the top and there is a slight brown spot on the top as well (near the seam)
My symptoms are exactly the same only threre are more than one capacitor bulged.My symptoms are exactly the same only threre are more than one capacitor bulged.
I have the same problem as of two days ago. Looks like the capacitor is marked C23 on the board...I have the same problem as of two days ago. Looks like the capacitor is marked C23 on the board...
My Pioneer DVR-225 worked great one day, zero the next. No power. No nothing. I'm NOT a techy; just a helpless old lady with a broken DVR. Are these things worth fixing or just part of todays disposables?My Pioneer DVR-225 worked great one day, zero the next. No power. No nothing.

Brought mine to a large local electronics repair facility, listed on Pioneers website. Reasonable deposit fee, but outrageous labor rate.I have lots of Unfinalized disks. Do I just chuck em' all? jj

Apparently there was a problem with some of the capacitors in these models. Your capacitor definitely is popped.
I had the same problem. The fuse was okay, but
two capacitors were blown. One was at location C23 and I think the
other at C17. I took it to a local electronics shop and they replaced
and soldered the new capacitors on for me. It only cost $16.22. They
were a 3300 µF and a 1000 µF.
Exactly correct. Bulging top caps at locations C19 a 1000uF and C23 a 3300uF.Exactly correct. Bulging top caps at locations C19 a 1000uF and C23 a 3300uF.

I also had the same problem. I am no electrician, so i took mine into Best Buy where i had extended service on it. The power supply is on "back order" and wont be here for 3 months. Basically, they're telling me, they cant or wont fix it. I'll be getting a new recorder, but I've been happy with this one.

There might be a connection that could be loose here to have your TV be turning off or there is a problem with the TV's power supply or a Tcon board problem or the power cord might be bad.
Hi, It seems problem with power supply board in Pioneer DVR-520H, possible causes for that symptoms are few dried up/ leaky capacitors, cold/ dry solder joints on circuit board or chip resistors would be devalued. Local repair shop will help you to replace bad capacitors, chip resistors in power supply board to solve this issue if you are not familiar with soldering work in circuit board. Hope these info will help you. Let me know if you have additional question. Thanks.
Power supply is the problem. If not under warrenty, open the cover and look for blown capacitors. If there are, try replacing those or have them replaced. Might solve your problem
This is a power supply problem.... the MR2920 stanby IC miss behaved, it power off and fail to power back on.
Solution, get pioneer power supply replacement or take the dvd recorder to your local electronic service repair to take a look at the power supply circuit.
click link -ebay shop selling power supply boards for 503hde/pe at 180 pounds you will have to contact him has he does not list them as pioneer are only ment to replace these boards or shops under contract with pioneer i changed mine and only takes min's when you have got the back cover off...
Could be a blown internal fuse or a fault on the power supply board. If you can check these things yourself look towards a voltage regulator as the main culprit. Good luck.
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.
no Sir there is nothing to do now because there will be no tracking of data apart from another pioneer dvr-225. Try inserting the disc in a similar dvd player!
Please vote me solved
