OK, have had the LA32R71WX Samsung LCD TV for around a year. Now have added an NAD T753 Amp with associated NAD DVD player. And also added SKY Digital to the mix.

Audio all working fine...Video has turned to custard!

DVD and SKY both running into Amp on component, component coming out of Amp to TV. Get a message that the "Mode is unsupported".....occasionally the tv flicks up a really hazy almost purple image.

I'm a novice and i need help..any one no what to do??

checking the user manual here: http://207.228.230.231/manual/NAD-T753-GB.pdf

i see the following:

NOTE: The T 753’s component-video inputs and outputs are fully wide-band, compatible with all HDTV formats. The T 753 does not display its
on-screen menus on its component-video output. To use on-screen menus, you will need to make an S-Video or composite connection between
the T 753 and the monitor/TV, and select it for menu display.

perhaps you should also connect a composite or s-video so you can get an onscreen display and configure the unit.

also:

The component-video inputs are not configurable. Selecting the DVD input routes the COMPONENT VIDEO
IN 1 to the COMPONENT VIDEO OUT jacks; selecting SAT routes COMPONENT VIDEO IN 2 to the COMPONENT
VIDEO OUT jacks. Note that the OSD does not appear on the component-video output.

This indicates that the AMP does no signal processing with the component at all - check that the video output modes on the DVD player and SKY decoder are set to something your screen can handle. Maybe try connecting the component video outputs directly to the screen from each device (DVD and SKY) to eliminate the AMP as the problem.

I have a 753 running component out from SKY and DVD no problem to a SONY TV

suggest you check settings on the TV as a first step, does it work on composite? Are the component plugs all OK? maybe swap some leads?

Thanks to Regs and CT,
I have the OSD working OK so no issues in that regard and have the DVD via comp1 and Sat via comp2 as per the manual but didn't have any success.

Have checked all leads (and to be on the safe side bought new ones) and they are working OK, have checked the component video out by taking the Amp back to supplier and running it through another TV and all OK.

Yes the TV does run through DVD on composite but cannot configure SKY as my sky box uses a skart connector to component out so no ability to set up composite or s-video.

Still looking for answers....

The SKY boxes i've had in the past let you configure what signal type was sent out out the scart port. Check that it is configured to send component out, rather than svideo or composite.

Also, are you sure your SKY box is definately capable of outputting component? While you can buy a "SCART to Component" cable it does no signal conversion and relies on the box outputting a component signal (which is different to the default RGB scart output). What SKY decoder do you have and where did you get the cable (i.e. did SKY provide it)?

Mode is unsupported

Your screen can handle maximum of 1080i - check that your DVD player is not outputting a 1080p signal. Perhaps if you can configure the DVD player output set it to 720p as that is the "optimum" resolution of the screen.

Oh, also check that your cables are connected right. Don't necessarily rely on the colours of the cables - check that the Pr Pb and Y connections are made correctly between the DVD and AMP, and AMP and TV.

Hi Regs,
Yep got all that stuff from the NAD electronics and Samsung sites as well as talking through some trouble shooting with Samsung...now at least have the DVD working properly on component. The scart cable is sky supplied and was originally sky installed to component 1 on my TV which all worked fine...
