A bummer indeed, silva. What I do with faulty LG main boards is cook them in an oven for 10 min @ 180 degrees. Amazed at how many I've been able to redeem. Doesn't always work, but mostly does.

HI Bruce; this time i have good news for now, update on my Vizio M421vt custom pic adjustments issue. Well today after doing again the factory default and complete installation in home mode and configurations, i went in the pic adjustments and adjusted custom pic settings to my liking and instead of turning off TV with remote control,(which is not the original for this model) i turned off TV on the TV control panel and a few hours later i turned TV on with remote and my custom settings were all there,already tried two times and all good,don't know if powering off tv on the tv control have anything to do with it,yet to be seen,maybe i have to turn off tv on the tv,keep my fingers crossed.

I forgot Bruce about cooking  motherboard;
i have fixed this tv already one time,after i had found it in the curve

i have fixed it by doing  the BGA chip heating process , 

i applied heat with a heat blower,  the same method as the Ps3 YLOD fix
tutorial, just by  heating first bottom side with low heat then with

this is my tv and the fault in the video

That sure is one scrambled picture in the video, silva. The hot-air method of reflowing the ball joints is fine.

I fail to see why turning the TV off at the control panel should be any different to turning it off via remote,

but then strange things happen in electronics. Bon chance, Bruce.

Hi Bruce ,i also think turning it off in the tv should not have any effect,what other thing  i remember doing  when started the  home mode install, i did the inputs one by one adding Pic adjustments also one by one,maybe that?
