Hi Wink

First of all, sorry for my english, i'm a french guy Laughing

My CRT monitor Philips 107S (17") has a pincushion distortion like this : ) (

When i start it, the screen is normal but when it gets warmer, the deformation is coming up.

If i hit the monitor, it sometimes disappears but the default come back in the few minutes and it's then definitive.

I've already checked the weldings on video pcb and main pcb but i didn't see anything.

I have the complete schematics of this monitor but i'm not electronician so ...

Confused Wink

Very Happy Have a close look at your soldered joints in the line op stage especially the ew driver and modulator-if you havent any visible dry joints you may have a board break-
