Grundig 32VLE5500WG (same as 32VLE5500BG, only external color difference) 32" LED TV, all plastic, very cheap construction.
It has a 19VDC 3.8A power adapter that seems OK, but no standby LED at all. With a laptop adapter I see that standby LED flashes, telling me that there’s something shorted somewhere. Put alcohol over main ICs and SMD caps, and first one burning is T1200 (not marked on PCB, and service manual doesn’t tell its name!!), SOT-669 package, "69100" marking. After some research, it’s a Nexperia PSMN069-100YS. It’s shorted.
Since I don’t want to order this silly thing, I use my database to find that I have a IRF530NS with matching specs. It’s a much larger TO-263 but I have it at no cost.
I’ve soldered Drain tab to PCB and wired Source and Gate pins. Not very beautiful, but no extra expenses, and it works.
Original power adapter works OK once the TV is repaired. I guess it protected itself when detecting overcurrent.
