hi Guys,
My lg tv when set to live tv will show full screen for around 20 seconds and then show a very small shrunk screen in the top left corner of the channel
i can switch channels but the screen stays mall
netflix displays in full screen
picutre test shows full screen
i have tried resetting the tv, power cycling, changing cables (coax) and nothing is making a difference.
anyone have any ideas on what causes this?
this is what the screen looks like https://drive.google.com/file/d/13FsP250_kHif9M2gb8jD5rvAY8PxrpNG/view?usp=sharing
any help is much appreciated
