Default Tuner ?

I'm not that involved - really not even enough to say using one - with VCRs.
A friend of mine asked me about a project he has in mind. He has a LCD
"display". He wants to know if he could take the Tuner out of a VCR, hook up
the necessary voltages and cables for the Antenna in/out, as well as
video/audio - to the LCD display, to make it work like a TV? If not, any
alternatives?

Your thoughts?

Thanks,

RM

Wow...what a brilliant idea!!....so whatcha gonna call it ...a magic picture
machine?....or maybe a phantasmagorical moving picture projector???....or if
all else fails....maybe even a TV!!!.
So lets get this straight...you want to know how to build a lcd tv, using a
vcr as the tuner!!!!!!????????.
Ok, first spend a couple of months, and a couple of thousand $'s...or walk
down to wal-mart and buy one.

Hey, it wasn't "my" idea! I said I wasn't up on VCRs. I just asked the
question as posed to me to ask! With all the stuff I see in this newsgroup,
hell I thought maybe someone would have thought of such a thing. Oh well, I
suppose that idea was far fetched too!

I'm guessing they have an in-car DVD player? It's not just a tuner, you need

I "totally" agree..... I just thought I'd ask anyway. Just goes to show, "I"
don't claim to know it all! I'm not one to "assume".
So, I ASK! Yes, you're correct in their set up. You gave me an idea too, to
work with and report back to them.

Thanks!

You didn't mention that before, a lot of people ask if they can use a laptop
LCD panel for something and the answer is generally no. If the LCD already
works on a DVD player then yes you can hook it up to a tuner, some tuners
even output composite video directly.

Sorry, my error. It is late and I was not thinking correctly. I should have
included that one last part. I've seen the posts you refer to. Probably why
they thought it was possible. Not being to familiar with the "computer" TV
tuners, "I" had even suggested trying that, but they said no way to control
channel change. I think the 5" tv would be a lot easier and cheaper - as one
other mentioned. UNLESS of course one of the VCRs he has available has the
required outputs OR such a tuner can be bought reasonably - to equal the
cost of a 5" tv or such.

My sarcastic response was based on the fact that it sounded like you had a
raw LCD screen, with no driving electronics attached, and were attempting to
reinvent the wheel.....or at least the TV.
Clarity in questions my son, is what you seek!.
Seriously, I was at the Home Depot (!!??!!) yesterday and saw the cheapest
LCD combo 20 inch TV/Computer Monitor yet.
It was around the $280.00 mark.

For many people, walking down to Wal-Mart would be the obvious solution.
To those who strive for technical knowledge and a challenge, building a TV
out of salvaged parts is irresistible.

The answer to the original question is that it might be possible depending
on what the input signal format is for the LCD panel and how much effort
one is willing to put into the project.

It's an absolutely appropriate question. Ignore the responses that suggest
this is the most stupid ever asked.

Sure, it's easy to go and buy an LCD TV. It could be much more rewarding
to put one together from parts, even if it does end up looking like something
held together with duct tape and bailing wire.

I'm top posting this reply since I didn't want to water down either response
or my original!

I guess the old adage plays out.......... I can't recall the exact words (I
just woke up and it's been a "long" night!) - the only dumb/stupid
question - is the one that wasn't asked. One won't know unless they don't
ask. And as I said, I don't like to "assume", we all know where that gets
us! And I never claimed to know it all! So, I ask!

Thanks for the replies, I shall forward them. And next time, try to include
"ALL" info. I do apologize.

Thanks,

RM

I've built more than my share of one-offs, prototypes etc. You have to know
what's really reasonable. You'd wind up with so much 'guts' from a TV or VCR
that it isn't worth hand building. At most I would try to add video and
audio outputs from a 12 V TV rather than try to scratch build.

Mobile tuners are available from several sources. Try MCM or PartsExpress.
OTOH, *if* you can find an old used 12v VCR (most were merely players), and
*if* the mobile DVD setup has line video inputs; it's a piece of cake to
simply hook the parts together. (If you can find the VCR, keep it in one
piece and gain the added functionality of being able to play tapes.)

Hello All!!!!!!!!!!

Well, they went out today and bought the smallest "VCR" they could find. So,
we'll see how they make out with that.

And if you need a mobile setup, a 200 w el cheapo inverter will take care of
that 120 vac el cheapo VCR. I use on in the van all the time, along with a
small telly, works like a hose. Today's modified sine wave inverters are
just plain outstanding! You had to grow up in the fifties like me to realize
how difficult it was to operate 120 vac equipment in the car. A real PIA
with the old vibrator units, noise, buzz, hash, you name it, it had it!

First one I worked on used tubes to invert from 250 VDC to VAC!

Of course I worked on lots of vibrator car radios too. Then there were the
hybrids with tubes with 12 volts on the plates and transistors for the AF
section. Lotta weird junk before transistors could do it all.

| with the old vibrator units, noise, buzz, hash, you name it, it had it!

First one I worked on used tubes to invert from 250 VDC to VAC!

Of course I worked on lots of vibrator car radios too. Then there were the
hybrids with tubes with 12 volts on the plates and transistors for the AF
section. Lotta weird junk before transistors could do it all.

I'm not too far behind you guys! I got into electronics when Vibrators were
still in, but being phased out. I'm betting the guy with this idea in mind
already has an inverter! If not, he'll have to get one.

Thanks again,

RM

Somewhere I think I still have an old 1950's power inverter which uses a
vibrator. Wish I still had the original box it was in when I got it at a
garage sale probably 15+ years ago.
