Standing TVs Vertically

[John Bennett]

[ukvac] Re: Standing TVs Vertically
Good point. As the cubs to have the vents on the side. A simple idea
would be to raise the monitor off its side a bit (with a few strips of
wood) leaving about 4/5 cm between the tabletop and the vents on the
side. This should improve airflow.

They aren't affected by electrostatic fields but are by magnetic fields
(thats how they draw the picture). try taking the small magnets off of the
tube neck of an old crt and disconnect the scan coils. Mars Bar to a penny
the dot doesn't sit dead centre, this is due to gravity.

Oh yeah, it is drawn by electrons flying across the tube, after all. And
they do have a (v. small weight). I'm surprised that you need magnets to
straighten them though, I'd have thought you'd just tweek the voltae offsets
etc....

I think the problem is that TVs are designed to stand one way. The
internal components are held in place by mountings that are designed
with gravity pulling them in one direction in mind - rotate the thing
and the internal mountings may be under more stress than they were
designed for. I would think a quality product like a cub monitor would
be OK though.

I would have thought that they were more affected by the earths magnetic
field for that particular region than by gravity.

So watch out if you import machines from Botany Bay (I think thats where
all the magnetic anomaly's hang out!)

Yeah, Do it. Cubs are fine on their side, the basic "hearing-aid beige"
BBC schools-issue cubs are near as dammit the same as Microvitecs "Arcade
Usage" ones that ended up in many UK cabinets, they just added TTL input.
They are damn good little monitors, but still not a patch on the gorgeous
Philips CM8833 mk 2.
Only gripe with them is the lack of contrast control after the TTL-RGB
hack has been done, so the colour/black ratio never looks 100% correct.
I just went over to an Archimedes monitor (my elderly CM8833 is on the
way out), and BOY can you tell the difference!, the Archimedes one is
theoretically the same spec, but the picture is lousy compared to the
Philips CM8833, buy one, just buy one yeah!...

Are you saying that with some cheap brands cut-backs were made on
solder and the components are only placed onto the PCB? ;-)

Therefore by turning it on its side may make some components fall off
the PCB.

I guess the manufacturers are covered as the boxes always have an
arrow on them that says this way up.

No, its the lack of good solid lumps of metal bracket holding things firmly.
Like, large components just soldered on, and kept there by gravity.
If you turn the PCB sideways (with the resulting bumps that invariably
happen while doing this) then the larger components stress the solder
joints and lose their grip on reality... Also, entire PCB assemblies just
held on with 2 wanky little plastic clips, as opposed to nice big machine
screws, also the lack of a decent chassis plate, relying on the flimsy
plastic casing of the monitor to bolt the innards to...
Ever looked inside a cheap TV?

Talking of TTL - RGB hacks, can anyone point me in the right
direction for some instructions/schematics/information on this.

Don't laugh but ...
I am sure that television tubes are made specifically for Northern and
Southern hemisphere markets. The only difference is usually that the
alignment needs sorting though I believe that in some televisions, the tube
is mounted upside down!
If you use the telly on it's side, will this only work on the equator?
You will have to get the thing re-aligned or move house to Africa. Surely
using an old PC monitor would be cheaper (See my other post).
Any TV repair type tech dudes back me up ?

[ukvac] Re: Standing TVs Vertically
The PC monitors I deal with at work come in two different
versions, Southern hemisphere and northern hemisphere. If you turn any
monitor on its side it will need to be degaussed first so be sure you flip
it before you switch it on.
The standard VGA spec for horizontal frequency is 35Khz so if
your monitor works at 15Khz you must be lucky. Maybe it was designed with
Amigas and STs in mind ?. Anyway, All the VGA monitors that I have ever
tried have not worked.

Thanks ... Once I get my Williams to JAMMA interface built I'll be playing
Sinistar on it, especially as I now have a Sinistar stick!

Thats why I chose to use a CUB ... oh and the cube design so it sits nicely
on its side!
