I have just bought a Sony PVM-14M4A broadcast monitor and it works great except it wont do NTSC at 50Hz, it just shows a monochrome image. I have not tried PAL60 yet but that will probably have the same problem.
Can I override the automatic colour system setting somehow?
Hello
The TV does not show any sign of life , I started the troubleshoot as this , no power Led, no reaction when pressing the power button.
I checked the Power coming out from the power supply, the 3.3V_standby is correct and steady, then I checked the 1.2V_standby produced by IC6001 which Is good as well.
So I decided to control the main IC , IC4000 , he does not output any oscillation on the Xtal, Then I am now bloacked there.
The schematic is downloadable on this website , the schema is weird because the processor is not represented with any Xtal output, but obviously it has one.
Thanks you for your hint and help.
