Yeah you're right,I noticed that too the heatsinks shifted.
 
I tapped,put light pressure but nothing happened.
 
I intended to reflow the mainboard but unfortunately not possible since both sides has components/SMD's soldered to it :-(
 
The question is,which of the boards is more likely to be faulty.
 
Why is the LED driver board blinking Red light??
 
Is that because the video processor of mainboard faulty/dry joints or because of the T-con?
 
Or the actual LED driver board itself faulty?
 
I cannot go into menu since there is NO video/picture but TV responding to remote or manual buttons.
 
The reason I try to fix the TV,'cause I like the borderless design and it supposed to have IPS-panel and I intend to used it as big PC-monitor in my room.
 
Of course I can buy new monitor or TV,but I don't like the idea of spending hundreds of $ only to have a throw away product which last till the warranty expired.
 
Thanks.
