    First off, I own this R15-500. I am geting steady reboots, I have read the forums and understand the HDD and power supplies fail. My question, I have a used R-15 300 from my neighbor (also owned, switched to Dish) are the power supplies the same in the 300 as the 500, and will swapping a used HDD from the 300 work in my 500? Normally I would dive in and check myself, but I am dealing with some back issues. Thanks in advance.

    Don't know about the power supplies. But I know you cannot swap the drives and access the existing recordings.

    Thanks, no understand the recordings would indeed be lost, kinda hoping the HDD would "reformat" and be functional....

    True, but you CAN swap the hard drives as all the R15 series use 160Gb PATA interface drives. (100-300-and 500 series)

    Unfortunately, you will lose everything on the drive you swap into your 500 as it will recognize it but not let you watch recordings on it forcing you to reformat it.

    The power supplies/motherboards/cases on the 100-300-500 series are all different because they are all manufactured by different companies-(RCA/Thompson, Philips/Magnavox, Humax respectively).

    PS: To reformat, wait for "Running Receiver Diagnostic Test" to appear onscreen and press the SELECT key on the remote and you will get a utility menu of diagnostic tests including the HDD reformat command.

    You may not even need to format it. Install it and fire up your DVR. If there are recordings showing on it, you won't be able to access them. Not sure if you can delete them. If not, then you will want to format. Otherwise, delete them and start fresh.

    Great stuff! Thanks all, once I'm a little more mobile, I will remove the cover, give it a try. ThomasM, I tried the diagnostic tests too, says temp: Hot, HDD: OK.

    I know the fan works, cuts in @ 123 degrees, out at 118. I will have to look in the forums again, I swear I read a post on how to have the fan run steady. My R16-300 runs @ 105 degrees, my Tivo DSR-704 runs @ 110degrees. I'm leaning to the high temps in the 500, are causing HDD or Power supply issues...or both.

    Make sure your DVR is located where it has good circulation. Placing it inside a cabinet, or on top of, or in the middle of, a stack of other heat generating equipment, can greatly increase heat related problems.

    If you are getting the R15-300 from your neighbor and don't care about the recordings on your old DVR, why don't you just activate the -300 and deactivate the -500. I had a -300 that worked terrific for me and noticed that I seemed to have a lot less issues with mine than did people with -100 and -500 models.

    I guess I could...but really, I enjoy tinkering with this stuff...

    So I pulled the cover today, found C7 1000uf 10V cap is bulged, I have seen others have replaced the C7 & C8 caps with 1200uf 35V caps, I have a 1000uf 16V. Should work ok? Right? Any input appreciated.

    That should be a suitable replacement cap. Let us know if that fixes it.

    As litzdog mentioned, that should be fine. There should be at least 2 of those. You might want to replace all of them since if one has gone the other will not be far behind.

    Well the C7 Cap has been replaced...after keeping my fingers crossed, the unit rebooted and is working. Now I'll wait and see if the reboot issue returns...I only changed one(C8 left alone, was not bulged)...not the steadiest hand, didn't want to push my luck! I'll keep you posted.

    I can't believe it. Someone who can actually operate a soldering iron today. I thought I was one of the last of a dying breed! :D

    Hey...lots of us old HAMS can operate a soldering iron. I had to replace 3 caps in the power supply of my SageTv extender when the tops bulged out and it started rebooting. Good thing Radio Shack still carried a few parts.

    Even though it is not bulging I would replace that other capacitor. Could still be bad.

    And as a somewhat young'un, I solder when I work on laptops... My favorite is replacing bad AC jacks on motherboards. Amazing how people manage to break those...

    Ah ha! After a week of no reboots it did it again today. 5 minutes after it re-loaded, the picture on Live TV, not recorded started to skip. The audio was fine, the video was not. After 15 seconds of that, it rebooted. I would have to say the HDD is going! Finally, an answer to the reboots. I'll have to try installing a 160 drive tonight! Hope it works, drive is out of a used R15-300. Any tips?

    Should be a pretty straight forward swap of drives. Just exercise normal caution when working inside. Make sure all connections are properly made, no loose parts left laying around, etc.

    If you want to get fancy, you can try ghosting the old drive to a new drive before you put the new drive in. Then you should be able to preserve any recordings and settings. I know copying using linux dd works. There are some threads around here on other ways to do that. Only question would be what happens when the copy process hits one of the bad sectors on the source drive.
