Hello and sorry you're having problems. I may be able to help, but I need to ask for more info.
1) Is this the model number from the back of the TV itself (the Insignia model number off the sticker)?
2) What is your experience regarding repairs- do you have a Meter, can you measure live voltages?
3) What have you done so far?

The model is a 60inch insignia model# ***** and we have the back off looking for damage
TV Technician: Aric, Technician replied 3 years ago
Thanks for the reply.
Please tell me exactly what the set does when plugged into power.
Also, exactly what the set does once you press the power button.
All of this is pertinent in narrowing down to the root cause.
Ask Your Own TV Question
Customer reply replied 3 years ago
It makes a clicking sound as it turns off and on
TV Technician: Aric, Technician replied 3 years ago
As soon as it's plugged in?
Or only after power is pressed?
Ask Your Own TV Question
Customer reply replied 3 years ago
Yes as soon as it's plugged in, goes though the on Ana off, the power light stays on but has no effect when pushed
TV Technician: Aric, Technician replied 3 years ago
Okay good, this means your Mainboard is likely at fault.
However, please set your meter to DC volts, ground the black probe to the metal frame of the TV, and use the red probe to test the pins labeled 5 volt on the power supply board. Let me know what you get.
Ask Your Own TV Question
Customer reply replied 3 years ago
Where exactly are the pins labeled 5 volts and do you have it plugged in
Customer reply replied 3 years ago
And on the multimeter is it dcv and which setting ex. 200 m 20, 200 or 1000
TV Technician: Aric, Technician replied 3 years ago
I'm afraid I don't have time to continue tonight, as I have two orders I need to attend. I will opt out to open the question up for others to assist.

Hello, my name is***** be happy to assist you.
Please allow me to ask you a few questions to diagnose the problem.
Select 20V DC on your multimeter, touch black lead to metal frame of TV for ground and touch red lead to pin-2 of connector CN801 of power supply board, pin is marked as STBY, plug TV power cord in and check.
What volts reading appears on meter?
Thanks.

Customer reply replied 3 years ago
Does it have to be plugged in
TV Technician: Shahid, Technician replied 3 years ago
If you are asking about TV then yes, it has to be plugged in power outlet.
Ask Your Own TV Question
Customer reply replied 3 years ago
5.20
TV Technician: Shahid, Technician replied 3 years ago
OK, is the 5V stay constant and doesn't go low while TV clicks Off and On?
Also, check volts on pin-1 on same connector which would be marked as PS-ON or some thing similar.
Does the volts go high and low on pin-1?
Ask Your Own TV Question
Customer reply replied 3 years ago
.07 to point 41 fluctuates
Customer reply replied 3 years ago
Checked it goes from .7 to .8
TV Technician: Shahid, Technician replied 3 years ago
Thanks for testing volts.
Now on opposite side of CN801 there is another connector CN801, set your meter to 200V DC range and use red lead to check VA and VS volts on that connector.
Do you get any reading?
Ask Your Own TV Question
Customer reply replied 3 years ago
Is it the opposite side of the power cord that we just tested
TV Technician: Shahid, Technician replied 3 years ago
Correct, CN804 would be located on opposite edge of this board.
I mistakenly wrote wrong number of connector in previous reply, it should be CN804
Ask Your Own TV Question
Customer reply replied 3 years ago
Put the red connecter in VA nothing
TV Technician: Shahid, Technician replied 3 years ago
OK and what about Vs pin?
Ask Your Own TV Question
Customer reply replied 3 years ago
Sorry the VA read .8 and have to vsand they were 0.00
TV Technician: Shahid, Technician replied 3 years ago
OK, please pull the plug of CN804 and again check VA and VS volts.
Do you still get same readings?
Ask Your Own TV Question
Customer reply replied 3 years ago
The VA is 3.3and the the vs both read 1.0
Customer reply replied 3 years ago
Would that be 200 dcv, or 200m....?
Customer reply replied 3 years ago
Are you still there....?
TV Technician: Shahid, Technician replied 3 years ago
OK, thanks for the tests.
It seems power board is not providing Va and Vs volts to scan boards located on either sides of TV and one of scan board would also be short/bad and usually on left side board goes out calls y-main board. Va and Vs should be 200V and 60V DC.
Please check following link to view the y-main board image..
http://www.shopjimmy.com/samsung-bn96-20048a-y-main-board.htm
Board swapping is only option here to move forward in troubleshooting process so swap the power board and y-main board in TV to see if it fix the issue?
If it doesn't then again check Va and Vs volts output as done in previous replies and if TV still makes clicking sound (on-off) then main board would be next suspected thing, not sure why these boards went out in TV, probably surge volts or lightning storm hit the TV?
Please check with following supplier to get replacement boards or search/google them with the part number off of required board to get price info...
