Panasonic TX-L50ET60E TV horizontal lines / flickering
My 3 year old Panasonic TV has started flickering a few days ago.
The lower half of the screen shows horizontal lines (more or less like a 3D display) for a few seconds, then goes back to normal for a few seconds, then shows horizontal lines again, goes back to normal, etc.
The problem occurs whatever source I use (TV, HDMI1, HDM2...). Turning the TV off and on, or a reset to factory defaults didn't help. Firmware is already up to date.
I uploaded a video to show this: https://youtu.be/wn1E-p6PYno
After a few minutes, the display changes to: https://youtu.be/suRb8cLbnjQ
Here are photos after back panel was removed:
Can you please help?
Is this a good question?
