Any I2C error ? Look at I2C diagnostics in the service menu.

Ok
Which board in the cine7 is used to control the grille and geometric adjustments?

Ok, no I2C errors thus.
The convergence driver board R762454 generates the horizontal and vertical waveforms. Try to replace it and give it a try.

I observed the driver board and found a pile of black layers on it. I don't know what it is? Will it affect functionality?

It is obvious that the driver board is faulty. I tried to connect the disconnected wire, but it took a long time and failed. I had to replace it with another driver board.

Yes, that was the advice too. So what's the outcome after replacing de conv. driver board ? Are the grid lines still distorted ?

Yes, the grid lines are normal, and the geometric adjustments are normal
Thanks!

Every time I turn on the cine7, the image will roll. The P676 Potentiometer may soon fail. I'm going to replace it.
