Sony TV no colour

Hi

Does anyone know what could be causing loss of all colour after about 30 minutes of watching? Its a Sony KVA2952. The colour of teletext is unaffected.

thanks
Dave

replace ct301 on the colour decoder pcb with a 15pf 50v cap, applicable on pal versions of the set not ntsc versions.

Thanks very much Gary, I will do it after a trip to Maplin, to get the cap.

Hi Gary,

I agree with you replacing it with 15pf 50v cap can be the solution for this problem.

Hello,

I agree with Gary and Power views.

I couldn't find CT301 but found CT331 which is the right one according to another thread. By twisting the adjustment by 90 degrees it stays in colour now. (Tip: mark the original position using some Tippex)
