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

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

Hi Gary,
I agree with you replacing it with 15pf 50v cap can be the solution for this problem. _________________ http://www.powercomars.com |

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) |
