Building power outage caused TV not to work

Hello, your freinds tv has a power supply issue, it is the part that accepts incoming outlet voltages. replacing the power supply may solve this issue it is not garanteed becuase the spike or drop in voltage may have cuased other truoble in the other circut boards, the power supply couldnt handle the imediate drop in voltage cuased by a power faliure when you try to turn it back on the circut is detecting that it is not working properly so it will cause this safety shutdown it is protecting your tv from further damage.
since your area or building had the power outage this may have cuased the power supply fualt. check the voltage test points to make sure they are correct. exchanging it wouldn't hurt at this point. best bet is to get a service manual for it and be extra careful do not touch internal parts they still have stored voltages if your not electronically inclined or dont have any electronic skillz, have a service center come out and check it for you.

good luck to you guys, hope this helps
