Hi all,

I have just recently discovered a big issue with this TV. It freezes and then shuts down. I do a power cycle and it seems to come back up for a while before repeating the issue. Tonight I managed to capture the artifacting that happens during the problem. I have order a new power board in the hope that it would resolve this but as the video I recorded shows, now I am not so sure. I have had 2 flashing red lights only once. Most of the time it fully shuts down without giving any diagnostic information.

To be descriptive because the forum doesn't allow me to post my link. The screen when it freezes has a sort of dithering effect which gradually becomes more and more pixelated until there is sort of snow effect. Then it shuts down. Importantly, when it powers up afterwards, the screen is completely fine.

Any help would be appreciated.
