Why have I replaced my power supply board and screen still goes black?
I have a Vizio 550I-B2 LWJ2PPAQ Tv. One day screen went black but had sound. I never could see any semblance of pic with flashlight check. I replaced power supply board - tv booted up and picture went black with sound in 5 minutes. I will attach images of original and new power supply as well as LED driver. One capacitor looks crooked but unsure if that means anything. 16 pin connection looks fine.
