To narrow down the source of problems, the player/tuner sends to my TV. When the TV (tuner) is operated without input from the player/tuner, there are no problems with audio. Removed/replaced cables from player tuner to AV receiver. Changed from optic to copper, without correcting the problem. Because normal operation generally returns at start up, heat must be factor.
Oh, when using the player/tuner for movies, there is no lost audio.
AV receiver that plays the audio from the player is fine with other sources of input.
Is it reasonable to suspect that audio could be dropped from random channels by the player/tuner?
Any suggestions for locating the problem OUTSIDE of the player/tuner?
*** Sorry, this is my first day on this forum, and I posted the above elsewhere before discovering this discussion about the MDR513H/F7
I just had my 515 fail after a power outage. Symptom is that there is no time or any display on the front panel and the unit will not respond, even after leaving it unplugged for an extended period and then holding the front panel power button while plugging back in. Just looks completely dead.
I Googled this problem and found a solution on the Fixya site that said that there is a push button switch on the circuit board inside the 515 (and 513) marked "RESET" and that after pushing it the unit will function normally again.
As posted in the main Sticky thread on the Mag HDD/DVDRs on 7/9/12:
I just noticed that the instructions here say that the 515 must be unplugged for at least 2.5 hours before trying to revive a "dead" unit with the soft reset (holding the front panel power button while plugging back in until the display lights up). I had not read that before popping the cover and finding the internal reset button, so I do not know if my 515 would have been fixed by doing the soft reset procedure. I unplugged it for about an hour before trying the soft reset.
I wish you'd stop advising people to open their units to fix this "dead" problem!
As you stated in your follow-up THE FIRST TIME you posted this same complaint (shown in 2nd Quote above), there is a non-invasive way to revive a dead unit: it's a Soft Reset AFTER LEAVING a 515 unplugged for 2.5 hours or any other Mag/Philips unit unplugged for only 10 minutes.
Your Soft Reset failed because you didn't leave the unit unplugged long enough.
I had this exact same problem on the exact same model. Followed your instructions. Voila! Fixed. Thanks much. If it happens again, I think I will drill a small hole in the case and use a toothpick for future surges and resets.
I give up!
Some people are impatient, and don't want to sit on their hands with an unplugged Magnavox for 2-3 hours. For them, its worthwhile to poke around inside the unit and use the "hard" reset button to bypass the "soft" wait period (perhaps they need to leave the house and want to get their timer shows rescheduled ASAP). The extended setting / clock memory in some of our toys can be a hindrance to "instant gratification resets" (I wish more of them had a hard reset option).
What other options have I?
The Soft Reset is mainly for machines with nothing in the display panel (no indication whatsoever, or black), indicating that it has no internal power.
Having a --:-- indicates your unit already has power but that it only lost the clock???

I've had the MDR515 since April 2011 and have been using it with great success. I have Time Warner coax cable hooked directly into this unit. For years, I have been able to successfully record programs from Time Warner cable (there is no cable box, just the coax coming in from Time Warner) and over the air digital signals, both with the one-touch recording and through the timer-recording. The over the air signals are strong enough that I don't need an antennae. I am still old-fashioned--I have a tube TV that I purchased in 1996. I have been unwilling to get rid of it because it still works just fine.
For the second time now in three weeks, I have awakened in the morning to find that the display clock on the unit is "stuck" at an early morning time, corresponding to the end of the timer-recording that I had set up for overnight recording (it did record the program that I had timer-preset). Pushing the power button on the remote of the unit itself did NOT power the unit up. Unplugging the unit from the wall and then plugging it back in reset the display to the correct time, but it still would not power up. So, it was time to do the soft reset, where it is unplugged for 2.5 hours. This did the trick a few weeks back and then I had to program all of the channels again. I'm still waiting the 2.5 hours right now to see if it will reset today.
I'm wondering what is causing this latest freezing. This has not happened before. It seems to be freezing up at the end of the timer-program recording--I'm guessing this because the time on the display matches this. For years now, I have been able to successfully pull in the cable channels and the over the air signals, recording programs in middle of the night, where the timer recording function has to change channels with my current set-up. Any thoughts?
Also, I have noticed in the last few days that the feed coming in from the Time Warner cable has some issues--i.e. when manually typing in a channel number, the screen stays black, but you can hear the audio; or a flickering of images between the previously viewed channel and the one just manually entered. I'm wondering if this could be disrupting the 515 somehow in the middle of the night when it's trying to tune correctly to record the timer-programs from these cable channels. I suppose I could test this, but am not looking forward to having to shut it down for 2.5 hours again if it crashes....
Now I don't really have any advice except it might be some sort of "cable game" they like to play to make your equipment do strange things... or your machine needs a hard reset rather than a soft one.
