Very interesting point. There is no power (voltage) to measure. And the connection from connector P89-3 to P14-3 in the PCB 4 is fine. But in the other side, I really don´t know what to expect to measure in that line. I followed the line for P14-3 in the diagram and this is connected to a coil and again to ground = 0V ? But an accident occured

I have checked the 154V (measured 154V) and 190V (measured 167V) that goes to the print where the tube is mounted. But don't have tool to check the 27,5kV. The tube doesn't glow.

Yes, it is the correct tuner. We have used this TV for many years before. And it doesn't display picture via scart or antenna.

Hi First of all sorry my bad english. I am repairing a MX7000. First it wouldn't come out of standby. But now the standby problem is fixed. Now i can turn it on and hear the sound normally, but the screen is completely black. It seems like the CRT is missing some power somewhere....maybe. But I can also hear the energising sound when I turn the
