My Philips DVDR3575H just stopped working.  It's a DVDR with an over the
air tuner and a HDD.  I figured the HDD would fail and soon after I
bought it I found on a video forum instructions for installing a new
one.

But instead, the whole thing went dead. Worked yesterday and two or 3
short power failures today. Now nothing displays. I had found the DVD
tray open (because I run it from another roomy and don't know when I
press the wrong button) but it went in fine when I pushed it. Doesn't it
have to be working a little for tray to go in?  Maybe it's the display
that has broken?   I checked the outlet and a lamp plugged into he same
place works fine.   The owners manual says nothing about a fuse.  Any
chance ther is one anyhow, and somehow the power failure blew it?

It's all wired in and hard to disconnect, especially the little red bug
that's stuck to the IR input. And if there is no chance of fixing this,
I'll just buy something else and tranfeer the wires, instead of
disconnecting them and confusing myself.

This is 15 years old and I recorded 2 or 3  hours of video a day every
day for most of its life, then played the 2 or 3 hours, plus I left it
on when watching tv live, and often when I was't even using it.  You can
see why I thought the HDD would fail.  Yet I don't think that could be
the problem today.

Thanks.  Very helpful.

That's just the guy who sent it in wanting credit for himself and maybe
his company.

The schematics and block diagrams are located fair far down in

the manual.  It appears that there are separate analog and digital power
supplies.  That might explain why the tray still opens/closes (analog
power supply working) but nothing else (they probably are powered by the
digital power supply).  I didn't see any fuses but the circuity is
extensive, lots of pin connectors separating the connections, and I may
have missed something.

Your decision of course how much it's worth in time, effort and $$ to
disconnect the device, open the case, and look for a fuse.  This appears

It's worth endless effort, assuming I have some chance of success.

to be a very complicated conglomeration of multiple circuit boards using
many ICs etc.  Well beyond my experience and knowledge to suggest
anything additional. Personally, it sounds like an appropriate activity
for a fully retired person.  Nothing to lose.  You can't break it!  It's
already not functioning.  You can prossibly find a replacement on ebay.

A few years after I got this, I looked for another because I knew this
would fail someday, and there were only 1 or 2 alternatives DVDR's with
Hardrive, and one was $600 and even it had some4thing I didn't like.

This week, when I first looked on ebay, before posting here, I found
they were no selling for 30 to 70 dollars, on ebay. Whoopee.  But one of
he ebay models I found on Amazon complete with a video review in which
he pointed out that one could not play one recording while watching a
different recording. That's pretty important.  At least I do it all the
time.

Going back to ebay, this time I searched on Philips and found a whole
bunch of things I hadn't found before, including 9, count 'em, 9
versions of just what I have now, ranging from a real auction that has
now 5 more days to run but started at $15.  Seveal are listed as Tested,
but only 4 of the 9 have remotes, and the box itself only has 5 buttons.
There is not much one can do, or test, without the remote.  But even the
ones that have remotes, am I to think they tested everything?  maybe
must that it turned on and the screen said Playing and Record (two of
the 5 buttons) and the DVD drawer opend (one more of the 5 buttons.  A
fourth is Power and the fifst is Stop.)  Did they even connect a TV to
see if something was coming out the other end?   They all promise in the
standards for Used that it works completely, but they can't even change
channels without the remote.  So they assume it works but I'll have to
ship it back if it doesn't.

I record everything I watch on TV using a tuner card in my desktop PC or network attached tuner boxes (HDHOMERUN), and appropriate software (SAGETV), and outputting from my PC video card to the hdmi input on the TV or through a FireTV box. If the TV is off, the PC scheduler turns it on for scheduled shows.

 I've got a pair of FLEX 4K receivers that pick up 15 ATSC3 channels but 7 of those are DRM protected so no longer usable.
Makes me wonder how long before broadcasters shut off ATSC1, effectively killing the DVR.

Who do you have to "subscribe" to to get them?
Or, does this just block off recording?
