Son was delighted to receive a Pi yesterday, but we cannot seem to view
anything, using an ancient Sony portable TV. The only conventional PC
monitors we have use VGA.

The Pi has a yellow phono socket for video output. The TV has a
conventional TV aerial input, and a Scart socket. We don't have a lead
with Scart plug on one end, and three phono plugs on the other, but I
did find an adaptor thingy that is a Scart plug, with three phonos on
the back. No lead. I plugged that into the TV, and used an ordinary
audio lead, with phono plug on each end, to connect the adaptor to the
Pi. Nothing. Went right through the tuning band of the TV, but zilch.
What am I doing wrong or, more to the point, what else do I need to buy?

Thanks.

If you're using the SCART input, tuning doesn't come into it - should be
on 'AV' or 'video'.

Connect it as you described with the phono and scart adaptor and select
the AV input on the TV. The Pi's output is composite video.

You won't find the Pi's output by tuning, you'll have to switch input to
e.g. AV1 for the scart.

Also it depends if the scart adaptor is an input or an output scart

On some Trinitrons the AV input is selected by tuning to channel 0. On
others there is an AV button on the remote. On others there is an AV button
on the front panel. The AV button has an icon if a square with an arrow
pointing towards it. Pressing it cycles through the available inputs (SCART
1, SCART 2, PHONO FRONT PANEL, TV)
Not all TVs have the full range of inputs.

Some SCART inputs can be switched between RGB and Composite, so that may
also need to be set - the 4th input on our TV can be RGB, Composite or
SVHS and can only be set from a menu accessed via the remote.

Or, on some of them (the ones I get) move a switch on the SCART adaptor.

It's PAL by default, so no need to wory about that here.

However, tweaking with the width & height might be to your advantage.

I use:

framebuffer_width=704
framebuffer_height=544

in /boot/config.txt to get 640x480 out of the composite video. It's just

No, i'm sure the Pi is outputting colour here (the bit about typing is
surely regarding the intial commandline screen., once you are into the

It sounds like something has gone wrong twixt the pi and the TV,

I could be wrong, but I think it is the column furthest to the right

counting from the top. Of course Sony aren't greatly consistent so it
could be the one that you indicate.

Or the TV has a YUV / SVGA style input mode and is looking for separate
chroma and luma signals. Feeding CVBS into a input expecting luma will
yield a B&W picture.

Well assuming the device is putting out composite video, then the single

the right input.

What is the form of the video out though?

Have you turned on the Pi? (I'm not familiar with it, but I assume that even
with no OS, it will give some sort of display.)

Have you got an equally ancient VCR that might have composite input? Or
perhaps a DVD recorder. Then the output of that might be RF-RF on the TV,
or SCART-SCART.

The SCART-phono adaptors, might be designed for output only (it might say
so).

Or you could wire up directly, but will probably need to solder: central
core of the yellow plug to pin 20 of SCART, and screen to pin 17 (download
SCART pinouts from anywhere).

Using RF tuning on the TV won't help if the input is via SCART or composite,
it needs to be AV input. You might be better off with a more recent TV,
which you probably have in your living room. (And in that case, doesn't the
PI have HDMI output?)

I have found four SCART adaptors, three of which are moulded plastic.
However, one is screwed together, and the yellow socket is definitely
wired to pins 17 and 20. I cannot clearly see whether it is as above,
or opposite. Would that effect colour?

A lot of money ;-) (Adaptors are expensive)

The Pi foundation glibly say "VGA is considered to be an end-of-life
technology" although every monitor has a VGA connector. The biggest
mistake they made in the design of the Pi IMHO.

I bought a new monitor instead - From what I can tell from the forums
most people pick this solution.

You Pi may have died when you plugged it into the TV. Most TVs seem to
have no grounding pin on their power socket, so their connectors may
charge up to rather high Voltage. if you plugged the PI in with the TV
on line voltage, there may have been a discharge through the Pi's video
port frying parts of the DAC.

However, one is screwed together, and the yellow socket is definitely
wired to pins 17 and 20. I cannot clearly see whether it is as above,
or opposite. Would that effect colour?

No composite video has the colour information encoded into the
signal. If you can see a black and white image there are two
possibilities:

1) The Pi is only sending a signal with black and white. A DOS prompt
would be just white text on a black background. You need to be sure
what the Pi is sending should should have some colour...

2) The colour encoding is NTSC rather than PAL. See other posts on
how to kick it into producing PAL. Does seem a bit odd for the
default of a UK product being NTSC though.

Don't panic Mr Mainwaring!

Got it :-)

Not entirely sure how, but I suddenly have what looks like a DOS menu.
Now the fun begins.
try typing startx followed by enter to start up the GUI which should
come up in colour.

Lose (rhymes with fuse) is a verb, the opposite of find. Loose (rhymes
with juice) is an adjective, the opposite of tight.

I hadnt thought of that :-)

That's probably the case. Default Linux boot stuff is VGA white on black..

Needs a flash card with a boot image set up I guess. And then an X server..

To people who know too much, it is a sad fact
that they know how little is really possible -
and how hard it is to achieve it.

Unless he has a functional flash card with linux, that will be the boot
loader I'd guess..

I believe you download a linux image and put it on a flash card and then
it will boot that.

THe OP has already said a couple of times he has had the browser
running, so he has got past all the linux boot stuff, and is in the GUI,
which is in colour

He said he had a DOS like prompt - I assumed that he has a Linux image
on his flash card already to get that far.

I haven't tried booting without the flash card installed.
