Question from Antony: Hello I am from Greece, first of all congratulations for your excellent helpful tutorials. I’m having a huge problem with my arcade monitor which keeps having faded colors at the right bottom corner (especially the red).
The effect of this disorder is like the red color fadding and turning into green and then gets back again and this changing (like slow blinking) sequence takes about 1 or less of a second.
I tried with a degaussing coil according to the instructions you give on youtube. This procedure clears all the magnitized fields of the screen except of this corner. Sometimes after many attempts I accomplish to correct the problematic corner but if the cab stays off for about 2 or 3 hours when I power it on it comes with the same corner magnetized and the rest is totally fine. I also tried to move it and spin it and I found that if for example I turn it about 50 or 55 degrees from the position you can see in the photo the washed red in the corner suddenly corrects. If I spin it more in order to be in an acceptable position according to the wall (cab’s right side parallel with the wall) then I get washed green on the upper right corner which can be corrected with the help of the degausser but I’m pretty sure that if I shut it down it will come back magnetized again more or less. I ‘ve done the position testing also in the center of the room away from the walls and other devices and the behavior of the monitor is exactly the same.

This monitor has also a degaussing coil circuit around the monitor’s frame. I searched the web this week and most posts had as a conclusion that the metal frame that holds the monitor in place has been magnetized. Do you think that this applies to my case? And it the frame is magnetized how I handle it?

Thank you so much for your time and sorry for my poor English, Antony
