Hi
Excuse my poor English, I'm French.
A friend gave me his TV A Lg 60PZ550_UA .
This one had an image with holes.
Here is one of the flaws

By activating the test pattern here is what I found
https://vimeo.com/271719070
I managed to really improve the image by setting Vy to +8v.
But there are still several shortcomings
https://youtu.be/Ockpf6fJa2I
This defect is clearly visible on the whites
https://img110.xooimage.com/views/7/...9-549f0b0.jpg/
On the black background I also notice a swarm of green and white dots.
These defects are almost absent on the TV antenna but very visible on a video via USB.
When I run a white clean the image is perfect during this test
I also rewelded the induction coils without any more success, and changed the ctrl card .
I don't know what to do anymore.
Thanks
Daniel
