TLDR; Single backlight LED popped no more power from Powersupply.
Hi I tried to keep the title short but will explained what happened here.
My 65lb7100 had a bad backlight led which was causing the TV to turn the backlight off. I took apart the TV to get to the backlights I powered it with the power supply to see if I can spot the LED. Then when I was powering each strip 1 by 1 I eventually got to which I assume was the bad led but it popped/burned and the lights shut off and i was unable to get anymore power from the supply.
I don't have enough know how on SMPS to trouble shoot fully but probing around i'm getting power on the primary side but on the secondary side there is nothing except 3.5v on the optocouplers and motherboard power cable. There is no visible damage to the board as well.
The Board is A EAY63189001 REV2.0
Here is a nice picture of the Board https://assets.shopjimmy.com/media/c...189001-top.jpg
Hopefully I can get this fixed as I don't know if I damaged the main board as well and don't want to have to buy a new power supply just to have it still not work.
