It's a Vizio with LG parts. PSU seems to be a common fault since ShopJimmy is selling repair kits. I opened it up and found C604A toasted there's also a burn mark above R275 just below where it says LGIT E-series 42.
A little burnt near Diode mosfet D603 but perhaps that's from the same cap explosion because when I test the diode it reads fine. 443 one way and infinity the other direction.
One thing that bothers me is I'm getting almost no reading off the two resistors below the blown cap, R603/R604.
About .4 ohm at lowest setting on multimeter but the new resistor in the repair kit reads the same. Colors are Brown, black, silver gold and black so that's 10ohm with 20% tolerance right?
I also read this thread https://www.badcaps.net/forum/showthread.php?t=26439
And budm mentions the resistor shorting so that's why I'm particularly worried about them but are they actually just like .8 or something? Are these resistors fine?
I will post pictures of the parts in the repair kit too. They sent me like three different ICs and even SMD resistors and zener diode. For what location I have no clue because they are marked with wrong designation. C604A is marked C9307.
