Assalamualaikum Technician friends! The video above will explain how to measure RGB voltage, and how to measure heater voltage on tube tv. How to measure the rgb voltage on this tube tv is easy to do, as well as to measure the heater voltage.
The matrix voltage or rgb voltage on this tube tv is the main voltage on tube tv, to turn on a tube tv well, if this voltage is lost it causes faded color tube tv, abnormal color tube tv.
It's different for the heater voltage, if the heater voltage is lost and drops, it will make the dark tube tv no picture. So watch it till the end, I hope it can be useful ^_^
