It's nice to see that even these flats-creens don't just get junked. Good repair.
I have a bit of a phobia about switched mode supplies, even though I have successfully replaced quite a lot of faulty caps in such supplies in my time.
The phobia came after I spent all day replacing 8 damaged FETs buried in a UPS (Uninterruptible Power Supply). A very fiddly dis-assembly job. I switched on 6 hours later to be greeted with an almighty bang and I now had 16 FETs showing nothing more than three blackened stumpy legs each. No sign of the plastic packaging at all! Gave up....
