hisense Q8600 randomly goes blank

[sln12]

hi all,

any ideas on what could be going on here, I have a 2020 hisense q8600 that randomly goes blank and becomes non responsive to any remote commands after an hour of use

thanks

if you can hear a high pitch sound coming from the unit sometimes ,its probably a capacitor in the psu ,common problem
