    1) What replacement caps did you use?

    2) See "A guide on how to troubleshoot 2 seconds to black"

    https://www.badcaps.net/forum/showthread.php?t=10419

    look at transformer section, but read through everything to doublecheck.

    3) Post clear focused pictures AFTER reading

    https://www.badcaps.net/forum/showthread.php?t=1868

    Take your boards to a window on a sunny day and use macro mode. Take a top down view of all your boards (front and back).

      Hi thanks for reply
      The caps have no name that i can see
      220-16PHT 220uF 16V 105'c have NA and
      100-16PHT 100uF 16V 105'c have a large H
      Bought from little diode

      Look again and they dont say low esr but assume they were
      The inverter board is a seperate from the main board and is new
      Will upload picture of board later as its dark here (UK)

      Took this on cam phone not very good but gives some idea of board

        Is your external PSU putting out the correct and stable voltage?

            Sometimes it just takes a pair of fresh eyes!

            I remember one university assignment where my friend spent 4 hours debugging his assembler code. He asked for my help and in 2 minutes I found the problem. It was something pretty simple, but he was so buried in details he forgot to check the simple things.
