2080 Machine, DVD drive, on start up will click and clack for long time and them will display error that "Media is unreadable and please eject".

This happens in all cases i.e. No disk, blank disc, Prerecorded movie, etc. So it seems the drive is unable to detect any media or no media.

Opened the unit up, and cleaned the laser lens, the spindle/hub gasket. On viewing the DVD unit on start up, it does spin the disk, start and stop about a dozen time and then fails. All other HD and tuner functionality works. Is it indicative of failure of Laser emitter???

I am curious as how the unit detects if their is media inserted in the drive or it is empty, as currently even when drive is empty it thinks there is an "unreadable disk". I have reset the unit using all possible ways, and it does not change this behavior.

PS: I have many other DVR units, but I am trying to fix it as to understand how the unit works, will appreciate any input, particularly from Master Wajo.

Yes, that is exactly what is indicated. The recorder cannot even tell if there is a disk present in the drive or not. The multiple read attempts suggest that the machine is attempting to determine if a disk is present and after a number of tries, it gives up.

Is it safe to remove the cover and check the laser-beam. It points straight up, so viewed from side should be safe, am I right.

If I disconnect the data cable of DVD, will unit operate only using HD? And or it is possible to buy replacement drive unit.

[THINKING OUT LOUD MODE ON]

Every CD / DVD Reader / Writer that I've ever owned had some sort of 'Protection' for the user. i.e. portable CD players wouldn't even attempt to read a CD if the cover / interlock was open.

Even if the Magnavox, of which I personally own 6 but never opened (or had reason to open) any, doesn't have any 'Protection', you're correct in that the laser (a very narrow beam) is pointing straight up and thus you could hold a digital camera over it to see if there's any output. (I'm basing this on the methodology for checking the output of an IR transmitter - as I said, just "Thinking Out Loud" since no one else replied. :bulb: :thinking:

Good Luck!

We bought a brand new Magnavox MDR513H/F7 HDD / DVD recorder back in 2011.

It has worked great over the years, but we are starting to have issues with it and decided to do some research.

While researching, I found that the back of my unit shows E2S01UD, but the firmware displays E2S00UD.

In addition, the combination of model (E2S00UD) and BE firmware (HD6A26972AH1E) that appears on the screen do not seem to be a valid combination (according to an earlier post in this thread).

Anybody ever seen anything like this before?

A known combo for the unusual history of the 513. You appear to have an "Orig. Late-513" model with the unchanged FW from the "Orig. early-513 model," as described in the first two sections of the help file here. Details repeated below:


513's may have EITHER ONE of the "Early" or "Late" Model #s shown below on their back-left sticker... most likely as a result of a transition in production lots.


Orig. Early-513 OEM FW - Apr-Jun 2010

Model: E2S00UD
DTV-S: 0x2A
FE: R60_001_000*
BE: HD6A269718H1E**
TT: T5011RDU@5*

*Same as 2160A.
**Same as 2160A with Oct 2010 FW Update.


Orig. Late-513 OEM FW - Jul-on 2010
Also released by Funai as a User Update for early-513's.

Model: E2S01UD
DTV-S: 0x2A
FE: R60_001_000
BE: HD6A26972AH1E
TT: T5011RDU@5


Oddball OEM FW for 513 - Mysterious FW Found in Several NEW/REFURB 513 - Various Mfg Dates

Model: E2S00UD*
DTV-S: 0x2B
FE: R60_001_000
BE: HD6A269726H*1E or 726V*
TT: T5011RDU@5

*There may be some of these "oddball" 513's with Model Name E2S01UD and BE FW 726V?.
Some 726H/V FW could lack the pre-titling of timer rec programs and program Skip features that SuperFW 727V has?


1st FW Update for ALL 513's (& 4th Update for 2160A) - 10/5/11

Model: E2S00UD or E2S01UD
DTV-S: 0x2A or Ox2B
FE: R60_001_000
BE: HD6A269727H1E
TT: T5011RDU@5

Click here for the 727H (and SuperFW 727V) FW download file and instructions. Save ZIP file forever for possible future use, like FW corruption or reverting to this FW after a future User Update that you don't like.

I've been having some issues with my 2160A.

Sometimes playback hangs for 5-45 seconds, no changes in the seconds on the display, then it resumes.

A few times, I have recorded OTA and ended up with 55-58 minutes of a 60 minute show, with 1-3 abrupt
scene changes, obviously something is missing at those points.

A couple of SYSTEM ERROR POWER OFF messages.

It seems like the first two might be hard drive issues, not sure about the last one.

I have started marking these titles as DO NOT DELETE, in case there are bad spots on the drive.

Any ideas?

Thanks

If you are able to delete all titles at some point in time, here's some advice that might help (from my help file):

We don't have a CHKDSK or other computer-like utility that we can invoke to read an entire disc w/o losing access to recorded titles. The best we can do is fill the HDD up with recordings to make sure we've "used" every bit.

To see if there are any adverse effects of this, I've been letting the HDD in my refurb'd 3575 with a "bad" HDD fill up with recorded titles and, when the HDD fills up, it just stops recording and won't record any more. This 3575 was always slow to start up, noisy, froze on playback of first three titles, wouldn't Initialize with Skip 079, failed Skip 013, etc. After several fill-ups, it now plays the first three titles and Initializes normally, so I think filling-er-up once in awhile is a good thing all around!

DanHuff tried my "fill-er-up" procedure to fix his "problematic" HDD... read all 6 posts to get the entire story of things he tried.

IMO, some people who don't do a lot of editing will benefit from letting their HDD get full yearly or every other year to keep all the bits active. You can do this slowly or quickly, as follows.
