I have a meter reader, and it is getting power. I'm not too sure about what the readings should be though.I shotgun replaced means, just putting it in then yes.

I tried the power supply first and then talked with a tech and he said the main board was the issue then.
Customer: replied 1 year ago.
I don't get any lights at all on the front of the tv.
Customer: replied 1 year ago.
What should the readings be? Does the tv have to be completely put back together to at least get some lights on the front of the tv?
Expert:  Anthony_Infotech replied 1 year ago.
The first check is with a meter we need to set the meter to 200vAC or near that and measure acros the powercord input to the powerboard you should read 120vac
Let meknow you are getting that

I plugged it in, and put on of the leads on the white of the ps, and got 45. I'm sure I'm doing something wrong here.
Expert:  Anthony_Infotech replied 1 year ago.
Well you have to make sure the meter is set to AC about 200volts AC will be OK or whatever your meter is as long as its above 120
Go right across the AC input lead that goes into the set that is with the red and black lead you should read 120vac this is the first check to make sure we are getting power to the set
