I have a DVD player here - most likely not worth repairing - given todays
prices - but it belongs to my grandkids and it is a "Batman" oriented
design.

Now - first of all, it's had a history of the littlest one stuffing a "few"
dvds in the slot. Each time, I took them out - player worked ok.

This last time it was brought to me, it wasn't playing at all. First of all,
I noticed - but not sure of the issue - which I'll get into "second" - that
the mechanism wasn't bringing the laser to the DVD. I manually corrected
it - then seen it wasn't playing that way either. I cleaned the player with
some DVD/CD cleaner supplies - and it is now playing "that" way. The second
issue which I corrected manually for the testing purposes is - the DVD goes
in - door shuts - the mechanism is supposed to come up injecting the spindle
into the DVD to rotate it and also place it in range of the laser - it is
not doing that. If I push it up "manually" - all works well.

Now - I've started to look at it albeit need some better lighting than where
it was. I'm not sure "yet" - if it is of a mechanical issue, electrical or
combination as to the cause of this problem. I started to look at it - got
away from it for a few days due to other work - but was in the process of
checking the mechanics. Not having a schematic on this, what is the
probability that an Electronics component "could" be faulty? I mean - so
far - the mechanics "seem" ok - but still checking. IF I can run this down
to even a "board" - there are only like 4 sections to this, maybe if I can't
narrow it down to "a" part - I can order the "board" or Mechanism. Most is
pretty much plug in and screws holding it down.

Anyone have any experience with this sort of issue? I've never had to do a
DVD/CD repair other than cleaning - before now - to really know the "inner"
workings. So, it is going to be a learning experience for me - in this
regard.

**Budget DVD players are usually throwaway items. Normally, you will replace
the entire laser and associated mechanism. Called 'the loader'. Unless you
can find a donor mechanism from another cheap player, you will probably need
to buy an OEM part. Naturally, you should check power supplies, as electros
are a common failure mode.

And, if it uses a rubber belt in the loading mechanism, a worn or broken
belt could prevent it from going into the reading position.

My guess based on the history of this thing is that it is a mechanical
problem from abuse.

The most common things for the mech failing to come up under the disc
correctly, are either misalignment of the mechanics, which usually means
that the tray rack has slipped a tooth or two on its drive gear, which is
usually related timing-wise to some kind of cam or anular gear that handles
the deck lifting, or a slipping belt. Normally, if it is a timing issue, you
will never get the deck to come up and lock, even if you try to help it. On
the other hand, if the deck does come up when helped, then that is almost
certainly a slack drive belt issue, assuming it uses one. When the motor has
to crank the weight of the deck up, after the relatively easy task of
sliding the tray back in, this brings the drive train under a lot of load,
and that is exactly when the belt slips. With direct drive systems, I have
had a similar problem caused by weak drive to the motor, but if that turns
out to be the case here, you might struggle to locate the cause without
schematics.

As an aside, your observation that the laser was not homing, is probably as
a result of the loading sequence not completing. When the deck comes up into
place, a switch is made, which tells the system control micro that it can
start the disc evaluation procedure, the first part of which is to check
that the laser is home, and if not, to drive it there.

Thanks gentlemen for your replies, I shall attempt further inspection of the
unit this week. To address one mans concern - I fully realize this may not
be worth repairing - price wise - I mentioned that in my initial post. But
it is the grandkids - so I thought I'd give it a whirl.

Thanks to all for your replies.

Knowing that children use it and the "littlest one" innocently causing

Therein lies the problem - got to put er in some "bright" light. Trying to
see what is going on in dim light - doesn't help! But - thought I'd tap the
resources of those of you here for some additional ideas, being this is my
first "internal" DVD repair.

Reading glasses? Hells fire - I wear glasses and see that stuff better with
them "off". Even the bi-focals don't help. But whatever it takes, we'll give
er another glance.

I don't know if you have a Maplin store near to you (you sound like you're
UK), but if so, you might like to get yourself a white LED. I have a couple
of these on the bench, one set in the end of an old Biro pen tool, and one
just soldered and sleeved to a pair of stout-ish wires. I connect them
externally to a set of NiCd batteries from an old cordless phone.

Those white suckers burn so bright, that I find them endlessly useful for
looking inside mechs, just as you are trying to do now. The one on the Biro
pen body, can be slid in where you can get straight in, and the one just on
wires, can be manouvered around 'corners'. Don't forget to check the specs
of any white LED that you get. They need a bit more voltage to drive them
than reds or greens etc. Also make sure that you limit the current.

No Bud, I'm in the U.S. and no Maplin Store here. But, if I look around, I
might have some of the LEDs floating around. I'll have to look and see.
Never thought of something like that. I use something else at current on my
bench, but I want to give that a whirl to see if it can help. If nothing
else, it might flood the immediate area - whereas my other method may not.
Thanks!
