Just got this TV for a deal, all it needed was some backlight repair. Powering it on, the backlights were clearly not working but the screen was fine. After some voltage reading I was pretty sure it was the power board that was bad so I replaced it. That seemed to fix it temporarily but now the rows of lights seem to be dimming individually. Do I need to replace the light strips now or if this something worse?

Update**

There seems to be 3 to 4 rows of lights, and when I powered the TV on is seemed only the bottom one was at full brightness. After about 10-15 minutes the remaining rows just powered up to full brightness. Definitely seems like the strips might be bad now.

Does the TV still have a picture?

it does! The top third of the backlight just seems to be a bit dimmer than the rest.
