|
|
Hullo,
I have an old Samtel monitor. One of the colour on the monitor is not working. Therefore I am not able to see RED colour. How do I repair it?. The video/data cable is secured inside the monitor, thus I am not able to check the cable also.
Please help |

What happens when you gently tap the top, side or back of the monitor? Have you tried a different monitor on your PC? Have you tried that monitor on a different PC? |

I have tried tapping on all sides but nothing happens. I have also tried with a different PC, but the result is same. |

Are you able to measure the voltage of the electrongun driver transistors while displaying a white screen? If they measure about the same then the tube may be U/S. If one is different, then measure back until you find the fault. You may need a circuit diagram for this. Good luck! |
