If the case; Be aware that Walmart and Black Friday televisions often use cheaper quality parts compared to ones that are seemingly the same model at bestbuy, etc... I would check caps on the powerboard and replace with nichicon or rubycon, not the whole pcb. Couple $ and couple minute repair. I've reflowed the solder on gpus, mobos, and power supply pcbs in an oven before and have been successful if it comes down to it...
