CONECTION TO LCD TV - BLACK & WHITE
I have successfully connected my Toshiba laptop to my TV using the TV out (S-Video) connection to SCART. I have now purchased a new TV which is HD LCD but upon connection the screen is black & white.

I have searched everywhere and tried any possible combinations, but obviously not the right one as I can not resolve it.

It must be something simple, as I was able to view in color in my previous TV, but now I only see black & white in my new LCD TV.

Could anyone please advice?

Most likely your laptop is

Most likely your laptop is outputting NTSC signals. TVs with SCART are probably PAL or SECAM only, which would explain why the picture is black and white (it's possible your last TV was NTSC compatible and this one isn't). Try adjusting the fine settings on your laptop to output PAL or SECAM compatible signals.

Or, you may have a bad S-Video cable or a bad S to SCART adapter.

Many thanks for your reply Matt. However, I double checked and the TV supports all types (PAL, SECAM, NTSC). It can't be the cables or the adapter either, as it was working perfect before I purchased my new TV, and I just tried it again with my old TV and works fine, i.e. I get colour. Any more ideas?

Not many. However, let's try

Not many. However, let's try a different S-Video device plugged in the same way on the new TV. If that ends up black and white, then  it may be a problem with the TV itself.

If I may step in here a second please. You say the TV set supports all the signal types, pal, NTSC etc etc, BUT did you try and go into the set up menu and see if the set is switched to the proper mode? Some sets do this automatically, some sets do not.

Yes I have Larry. Thanks.

Ah! OK nothing wrong wih connectors but... my new TV is freeview ditigal, therefore I didn't have to connect it to my old digi-box. However, now I connected the laptop to the TV via the digibox (as was before) and I get colour! Only problem is, that I have now messed up the display settings, by playing around trying to get colour, and the output to the TV is not good at all. A bit fuzzy, still colour, but I think it is the resolution that needs adjusting? Problem is I have no idea what the original settings were!!!???

That was a good thought Larry

That was a good thought Larry. Some TVs don't make that switch automatically.

If using S-video, the ideal resolutions are low. For NTSC, 720x480 is the right res and shape, but 800x600 (a common PC res) usually looks good. If the LCD is widescreen, you could try 848x480.

Try those, but let's take a step back here for a minute. S-Video is the least ideal way to connect any computer to a TV. In the analog world it's the only choice, but maybe your LCD has some more "PC friendly" connections.

Tell me, what kind of laptop is it (does it have a DVI, component video dongle, or VGA out?) What kind of inputs does your LCD TV have?

Thanks Matt, I appreciate your help.

Not quite sure if the above helps... The laptop has an RGB Monitor Port and a the TV Out Port.

The TV is a Technika LCD32-207 and has image quality up to 1366 x 768 pixels. SCART and HDMI sockets. 16:9, 32". Video and Audio inputs, Component Audio inputs, as well as Component Video Inputs (YbPbr). It supports PAL/SECAM B/G D/K K' I/I' L/L'

Do the above make any sense? Would you be able to tell me the ideal set ups, as far as cables, resolution, colour management, etc. is concerned?

Many thanks.
