sharp lc-49cug8052k
Hi guys anyone have a link for the latest software update for sharp lc-49cug8052k i have tried updating it in the tv menu says upto date but its from 2018 issue apps etc freeze and apps slow to respond freeview and same apps played through firestick/hdmi playback all work ok
Edit have now done a factory reset tv still doing the same thing on apps the app freezes then after a while tv reboots and goes back too normal freeview tv channel. so guess it is a mainboard fault as davi.p suggested.Last edited by vinceroger69; 10-16-2024, 06:44 AM. -
