sky:flashing picture

[sonynut]

having watched sky through the uhf connection since it was installed decided it was time to invest in a decent scart lead and watch it through the scart connection in glorious rgb.what a disapointment the picture on the channels i mainly watch bbc1 sky sports seems to be constantly flashing channels like itv1 sky movies are perfect havent checked all channels but ones i have seen some flash some dont.
my tv is a sony kv 25x5u connected with a profigold scart lead to an amstrad digibox.am getting a sony kv32fx68 delivered on tuesday hope this isnt the same but suspect it will be.
anybody with any ideas on what the problem is or am i stuck with it.i'll be more than a bit [word removed by lynx]if i've spent £700 on a tv and i cant use its supposedly superior rgb picture quality
any help much appreciated

It sounds like a set up issue. The KV25X5 is capable of displaying an RGB signal. Are you sure that you are using the correct socket on the sets rear pannel and selecting the correct input with your remote handset ? Have you instructed the digibox to output an RGB signal instead of composite ?

 

[sonynut]

yes to all the above,can't understand why some channels are flashing some are perfect.
are there any differences in the quality of channels on sky.
if its like this when the kv32fx68 arrives may have to dump sky for ntl though its more expensive.

Whats the Sky signal quality showing ?

 

[sonynut]

strengh 70%
quality 80%

To verify the integrity of the cables and that the tv is accepting an rgb signal, can you substitute the Sky box for a dvd player- set to output rgb, if so does the picture now improve or remain the same ?

 

[sonynut]

excellent picture with the dvd

Can you try a subsitute Sky box ?

When you say 'flashing', do you lose the colour as well (the picture sometimes changes to b&w)?. I had this with certain digital channels on my old Sony 25". It was plugged in via scart, but not rgb (awful picture in that mode). Since then i've bought a new 32" wide, and with the same digibox (grundig), the flashing seems to have completely stopped (now watching through rgb as well).
