OK, have you tried to disconnect TV from internet (if it is connected to modem/ router) and check if TV stays longer or shuts down?

Cannot as tv won't stay on to check
Expert:  Shahid replied 2 years ago.
Its easy, if TV connected through Ethernet cable, just unplug it from TV or modem.
If TV connected through wifi, turn Off the router for a while and check.
Please bookmark this page/ save the page link to open it up at later as we might disconnect when your turn off the router.
Thanks.

Repair cost
Expert:  Shahid replied 2 years ago.
OK, mostly this kind of problem occurs due to failing main board of TV where all video input jacks are located, main processor chip detects some internal failure and TV shuts Off due to protection mode, swapping the main board in TV will help to resolve the problem.
Required main board of TV would be available around 50 Pounds and local TV tech would charge around 50 to 60 Pounds as labor to replace it.
Please check following link to view main board image and price info..
