Just wanted to add a little bit to the repair tip for this model. I read the tip for intermittent colour by plamensl; "replace trimmer CT332, short pin 11 of IC331 TDA4510 and adjust trimmer CT332 for near stationary colour".

Thanks to this I found the components and as I didn't have any spares I just reflowed the solder on all of the pins of the two components. There has been no trouble now for about a week Smile

So, before replacing CT332, try reflowing the solder, it might save you a lot of work.

Thanks for the wonderful database everyone!

Hi
I have this set and a similar problem. Just want to check it is the same.
TV normally goes into black and white mode when my son is using a PS2 plugged into AV2 at the front.
When this has happenned the normal TV picture, AV2( DVD scart connection) and AV3 (front connections) are black and white.
AV1 however (freeview digibox scartr connection) is still colour.

Is this the same problem?

probably the same cause but best cure is to replace ct332 with a 15pf cap.
