A little guidance in troubleshooting (Sceptre x322bv)

[rescue341]

Hi all,

I have a 32in sceptre (x322bv) that died the other night. After some fussing with tech support they have decided to not be very helpful. So knowing its not like a can break it more I did a little researched on general tv repair and the issues with this particular model then pulled the back off and found a single board that seems to be the PSU and control board in one. This has kinda thrown me for a bit of a loop because all of the information i have found has told me to test voltages between the psu and control board. But with this being a single board as opposed to multiple boards connected with wires. Theres not really any clear place to prob and Im hesitant to randomly stab at 400+ volts

So after a little more research i found out that most people fix this model by replacing the entire board. So i found an exact match and ordered it. But then I read a post on here. That suggested checking the screen with a flash light to see if there was a picture at all. Sure enough there was. So clearly the back light isnt working.

My main questions are

1) could replacing the psu/control board fix a back light issue or is that just a wasted repair?

2) What would be a good next step in trouble shooting this? This is the first TV i have cracked up so being in such unfamiliar territory im just not sure what the next action should be

Thanks for the help guys

There should be wires that go to the panels backlight, measure the voltage, If there is voltage (maybe around 100 volts?) on the plug I would suspect a bad led in the panel
Post pictures so we don't have to guess
