Has anyone tried this TV with a ZX spectrum 48k?

nineties but it won't pick up my speccy's RF signal (not sure if it's
my modulator or the TV set).
I've decided to take my chances and buy the TV linked below in hopes
that it might work better:

It does have the RF input (I haven't modified my speccy to output
composite) so I'm hoping to use that. Failing that I'll try to mod the
machine to output composite and hope to be able to use the composite
input on the TV.
Anyone had any luck with this particular TV set? I really like its
small size and that it's 4:3 and not 16:9.
Now, my TV hasn't arrived yet and the wait is killing me but I figured
some of you good people in this group may have tried this combo
already.

Hi!
Maybe you can try it on an other TV-Set you know (friends, aunt,
grandma etc.). Try to find it on channel 36, if I remember correctly,
on older TVsets you can turn a knob and adjust it mechanically like on
an analogue synthesized tuner (e.g. FM radio). Even B/W TV-sets should
work.
Newer TV like your 99' built, has digitally synthesized tuner with
fixed channels from hz to hz. Homecomputer are mainly on channel 36.

Hmmm, I have heard about troubles with newer TV (TFT and such flats). I
have no idea, but I would try to test it before buying :-|

I would try to test your speccy on an other TV set primarily.
Does the speccy make 'klick sounds' when you press some keys while it
is turned on? (That would mean it is not broken at all.)

My speccy is alive, I can see a fuzzy faint picture and it clicks when
i press the keys. Borrowing an old telly is out of the question though
because I live in Canada and nearly every TV set here is a 60Hz NTSC
only system.

PAL TV-sets can display 60Hz more often than not.
While you have a TV-set which can sync to 50Hz, you could try the other
Video-Input possibilities. Scart connector (RGB) or Video-IN connector
(RCA, a yellow cinch like connector only for video).
RGB is a little bit complex task if you plan to do it on your own. I
have never seen original RGB-Modulator extension hardware for the
16/48K Speccy. There are some do-it-yourself schematics to find. Best
picture...
RCA is a lot easier task and delivers also a stable noise-free picture.
The built-in RF-Modulator of the speccy has to be removed (not a must,
but you won't go back :) You can return the RF PCB anytime back!), it's
a tiny PCB (printed circuit-board) which can be removed completely,
leaving the 'RF-Modulator cage' with its RF-cable socket, which can be
used for the RCA Video-cable later.
leaving two wires which led formerly into the RF-Modulator.... you will
need them for the small circuit you have to make/build to have
Video-OUT. It's just 1 capacitor, 1 transistor and one resistor AFAIK.
Hmmm, I don't find it on the homepage anymore, but I have the video-out
schematic archived if you would like I can mail it to you!
It increases also the chance to get a picture when connecting to modern
(crap!!) TV-flats, IMHO.

Here is a nice text with pictures if you are a beginner in electronics.
