Pb with Sony CPD-20SF2T Monitor
Hi everyone !
I have a pb with a sony CPD-20SF2 monitor. Picture is very sink, i have no more green color on display, only red and blue, and big black horizontal bars. I tried to check adjustments on the monitor itself, but picture is still bad.. When i increase luminosity, screen becomes gradually black, and when i decrease, it becomes brighter... I have obtained Sony Service Repairing plans for this model. Where should i start to search ? Has someone already solved this kind of problem ? Thanks for your answers ! Sincerely Erik |

This would require proper troubleshooting. Going by your description,
this is a failed component(s), not an adjustment. The power supply would have to be verified, and then analyse the problem by following the signal path with a scope to see what the cause is. Jerry G. ====== |

Thanks for your help , Jerry. When you say "signal path", you mean video
signal or electric signal on the output of the alimentation ? Someone told me i have to check all capacitors because some of can be dry. If you hear more informations, don' t hesitate, sincerely Erik "Jerry G." a écrit dans le message news: ... This would require proper troubleshooting.
