    Samsung PS-42S5H blown y-buffer

    Hi
    I will order a set of new y-buffers to this one, as the owner really wants it.
    Question is, should I go safe and replace the Y-sus as well?
    Could a bad Y-sus damage the new buffers or is it very unlikely?
    I would prefer to replace the y-buffers first, and if y-sus is bad, replace later.

    Cheers dudes

      Check Vscan & Vsch voltage on Y-main, plus 5V for buffers.
      If possible use a scope to verify the sustain waveform too.
      Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
      For service manual, schematic, boardview (board view), datasheet, cad - use our search.

          Can this be done without the Y-buffers attached you mean?

                  Samsung BN44-00262A H37F1-9SS power supply help finding blown value components!
                  by cheeky2
                  This Samsung combined power supply and inverter was replaced a while ago from a Samsung 37inch LE37B530P7W TV. However I would like to repair this one.
                  I have replaced the Mosfets Q1820 and Q1821 ( FDPF7N50U) which were both blown and the fuse FM802S. The schematic for this power supply that is attached doesn't relate to this power supply as the driving transistors and diodes are D1830, D1831, D1832, D1833, Q1811 & Q1810 are nowhere on the schematic!
                  Does anyone know what the components for D1830, D1831, D1832, D1833, Q1811 & Q1810 should be? I ask as I did change the Mosfets...
