Help locating a replacement voltage reference for power supply
I got a free AVOL 55” tv that wouldn’t turn on. After taking the power supply out I saw a broken piece I was able to find out to be a voltage reference. Pretty good chance it’s all I need. It’s on a LK-PL55020B power supply. It’s got two sets of identifiers. The first is TL431 and the second set is 0918. I can find a bunch of tl431s for real cheap, but I’m assuming the 0918 is identifying something specific about this type of tl431. Any idea how I can find a replacement? Thanks.
