I think a disc got stuck in the machine and there was a hi pitched sound but the sound disappeared. I got the disc out by sticking a pin and pushing it to the left like the underneath of the machine sd to do. I can't get the machine to stay on. what can i do???? i want to tape my mom's favorite movie.
Dave727,
C14 & C20 are in fact 2200uf @ 10VDC. C15 is 1000uf @ 10VDC. After reading these posts, I took a closer look at the ps board, and sure enough C20 top is slightly ballooned out. We'll be replacing all 3 with 16VDC caps shortly. BTW, the high pitched whine is from the power supply because it's a switching supply and creates some HV.
Thanks for the input!

C14 and C20 got my DVR 1600 running again fine thanks guys
I agree with dave727. DVR1200 fixed as advertised. Replaced C20, c14 and c15 and all is well. Many thanks.
DVR 1200 do use 2200uf 10v as stated newer models go to the 220uf 16v. I do not know if 2200uf10 v and 220 16v are interchangeable, but they both seem to be blowing. I also had to replace th capacitor C15 as well as CV20 and C14. If you look at the top of the capacitor at a 90 degree across the top and they are crowned or mushroomed it means they have blown. and brown goo is a is a good indicator.
Gmikulski's solution above is SPOT ON! I had a Cyberhome DVR1600 that had "NO DISC" problems for a year now ... just saw this post, opened the unit up, and C14 was blown (brown goo out the top). I quickly replaced C14 with a 220uF (note, the cap is 220uF, not 2200uF as listed above) 16V cap and the unit works perfectly now. Awesome!!
Replace c20 and c14 on the power supply board---they are 2200uf caps 10 volts--unit works fine again--
I have had the same problem desribed above for quite a while now. The high pitched sound in my case was not actually coming from the DVD Drive (the sound was present even with no DVD in). Tore open the case and found it was coming from the power supply board. Which makes since in a lot of ways. No obvious spots of burnout on any resistors. With a new power supply board not adding up right in cost next to a brand new unit, I'm going to troubleshoot the broken board I have with a couple electronics instructors. If interested in answer email me at [email protected] and I'll let you know exactly what makes these power supply boards crappy.

Have the same problem...unable to power on the unit. I have already replaced two faulty caps (C20 and C14). Power supply still has high pitch whine...possibly a bad diode???
I purchased cyberhome dvr 1600 2yrs ago it has not worked in a year. I got a high pitch noise coming from, I believe, the power supply. There is no signs of damage or brown stuff anywhere so I,m pretty sure its the power supply. Where do I get a power supply unit?
I have a dvr1200 that wont turn on and has The high pitched sound coming from the power board also. If I unplug it plug back in it will show the time on the display,along with the sound but when i push any of the buttons on the unit the display goes blank but still makes the high pitched sound?
useing a auto stethoscope trying find were the sound was coming from lead me to c5 is that a ceramic cap. looking at the cap c20 c14 c15 don't see them mushromed or leaking but maybe I'll just replace them they should be available from radio shack? thanks
i have a cyberhome 1600 with same problem. thought disc was stuck causing it to make hi pitch sound. took disc out same way you did but hi pitch noise is still there and it wont power up at all don't know what else to do please help anyone out there
I have had the same problem with the high pitch plus it was getting pretty warm. I only used the dvd about 6 times and only tried recording twice. It has been sitting for about a year and a half on the shelf unplugged. I was afraid it would catch fire. I opened up the back to see if anything looked burnt but nothing looked out of place.
Mine was manufactured in August 2005. I would like to know when yours was made.The company should do a recall if they had any class.
