SLES 2012SVS40 mistake, need help

[disorder]

hello guys,

i've got a samsung tv to repair with dead backlight
it is a edge backlight with two SLES 2012SVS40 strips.

done a mistake with my order and received a 10 pins strips kit

but the tv got 6 pins strips

do you know if i can use them with some modifications ? or not ?

thank you

Re: SLES 2012SVS40 mistake, need help

Yes I've done this before with a 55" ES. 10 pins is wired for 4 banks and 6 pins is likely 1 bank. You will need to connect the four banks in series.

hello

thank you for your help
don't understand the jump wire you made
there is 4 ramp of leds on each strip, so why just jump minus from one ramp to plus and the ramp after ?

so i try just jump wire like i thought (but maybe it is not good), all leds bright up but backlight is blinking, all leds at the same time.

can you explain this to me ?

thanks

Re: SLES 2012SVS40 mistake, need help

Sorry, misread my own notes. The 3 wires from the PS are to drive two parallel banks so the 4 banks were wired in series to create two banks to drive from the 3 wires. You should be able to verify from your old strip and the legend on the PS board connector. Not sure if the 40 inch is the same but should be close or similar.

hello

i've got flickering backlight, and i don't find why.
voltage on input line of the backlight is 130V not really steady but little fluctuation.
the return of the first strip is at 130V too, but the output of the second strip is 6V and really really unstable.

what can do this probleme pls ?

hello, sorry but i misread the fix.
in fact there is 4 bank of leds (on 6 pin strip) drived bye 3 wires by strip
i didn't do like your website but i do this :
left strip :
pin 1 and 6 (1 is upper one) together, and wired to positive wire from board
pin 5 and ten together and wired to negative from board
jump pin 3 to 4 and 7 to 8.

on right one exactly the same but pin 1 is lower one.

now backlight works fine.

BUT : i have new issue on this one, half screen only. defective left panel board.

this board is t400hvn01.0 XL; on this one i have very very hot Q001.

does anyone alreay seen a Q ic short on panel board ? already seen caps but this no.

thanx
