Samsung BN44-00262A H37F1-9SS power supply help finding blown value components!

[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 Q1820 and Q1821 ( FDPF7N50U) however they blew again (these Mosfets replaced could have been fake ones from China). I did replace the diodes (D1830, D1831, D1832, D1833) with KDS184 as I did find one blown. However the schematic doesn't show Q1811 and Q1810 and I suspect the KDS184 (D1830, D1831, D1832, D1833) might be wrong as well!
The Mosfets Q1820 and Q1821 ( FDPF7N50U) are circled in red on the images.
So does anyone know what these diodes and transistors should be D1830, D1831, D1832, D1833, Q1811 & Q1810 ? Circled in white for diodes and blue for Transistors on the back of the pcb.
This repair has been on the back burner for a while and I would like to see the back of it!
All help will be appreciated.

Just managed to find an image of the schematic see attached file.
Which turns out D1830, D1831, D1832, D1833 are KDS184 and Q1811 & Q1810 are MMBT2907A

You have to change the blue caps next to them also

Thanks I assume you mean C1890 and the C1891 the 220pf 1KV if they are 1KV I may just uprate them to 2KV as I have some.

Yes, when the mosfets go or vice versa it blows the other one. And if they didn't blow, they probably will soon. Yes change the caps and see what happens, of course the mosfets again now

The Mosfets were changed a while back from a different supplier. I am just going the check the diodes and transistors this coming week as I will really have to remove them as there are a few components that will affect testing if I don't! Hopefully I will report success later on this coming week!

Hi, you have to check every elctrolytic cap esr+capacity before change other parts, and also the pulse control chip that belongs to the two mosfets is prone to break, especially if you measure D-G short on the mosfets..
