      Is your board FSP212-3F01?
      If it is, it is known to have bad transistor and Zener diode.

      Unless I have bad eyes, the diode and the transistor do not look like it burnt up to me, if they are, that would have blown the main AC fuse.

        I suspect you'll have to try reading the part numbers off the side of the devices. The schematic is useless in that respect and has no part numbers, unfortunately

        Unless you can find another TV that uses the same PSU and has a decent schematic. I have looked for another but can't find one so far.

        Going by http://s807.photobucket.com/user/bud...ml?sort=3&o=16 it looks like Q4 is an AP04N70BF

        You'll have to figure out D7 though. What does it say on it?

          by sam_sam_sam
          I have a Lithonia Lighting 65-Watt Gray Hardwired Compact Fluorescent

          I also have back when Light of America had these light bulbs available for yard lights

          The issue with Light of America was the blast boards had all most certain board failure while bulbs hardly ever fail

          While the Lithonia lighting fixture has all most certain bulb failure

          So I have modified the Lithonia lighting fixture to accept the Light of America light bulb and see how long this will last

          I have only had this light fixture for not more than a year if it...
