Tv Smarttech 43 smd components broken identification

[labello]

Hello everyone i can't find anything about this smd because it's completely destroyed, no mark on it, the tv turn on backlight is on
but no picture, I check voltage on t-con board any voltage, the fuse is good. I don't know if i can replace something similar but I don't know what. Thank you so much for the reply

It is necessary to indicate not the TV model, but the motherboard number (model, chassis...).

Thanks man ..
Here those pictures about chassis and marks on the board, i just taken

Thanks man, do you think can i find this mosfet in other mainboard? Or should I order by new one..? Thanks again

ooow that cooked, Gods house is below it the "I AM" 🤣, once repaired do not watch porn on it again or God will nuke it a second time from his house.

As you where fixing stuff and been all productive...

Guys I replaced the new one and again he blown up. Dammed something couse this problem 😡

[labello]

Guys i replace a second one and turn it on without t-con connector and it doesn't blown up. Then i measure bolt pin on board where two cable red comes and i have 12.30 both pin. So it's seems the problem is t-con itself...🤔 i also checked the fuse on t-con board and it's fine. It's very strange isn't... thanks again

This mosfet is a 12v switch to power T-CON, panel, look for T-CON, what could be shorting...
Also check the LVDS cable itself to see if it is shorting.

Hi the cable is okay.. the problem is i can't check those voltages when the tv is on because the mosfet blows up again.. Thanks

Why supply power, you need to use a multimeter to check what is shorting on the t-con on this 12v bus.

this has nothings to do with T-CON.. T-con had its own Fuse... the problem still at MB... DC to DC of 12 VCC not only one Mosfet SI3407-TP. the other one too... its like PNP / NPN circuit

[lotas]

What other circuit is similar to PNP / NPN? Do you know how the switch (mosfet) to turn on the panel (T-CON) works?

Panel 12VCC never being active circuit over all brands of TV... this mean we do have I2C to switch controller Q or IC which yours schismatic just focused on the (mosfet) self.. which this didnt help.

OP . terminated this circuit at all.. and make active DIY. DC to Dc 12V regulator feed it from any point you have >12V with CAP 2200Uf 25 V and feed it it direct to T-CON fuse ( we did this DIY before over this forum ) end.

No of course, that's why I'm here , to learn .. thanks

Hi thanks for the reply.. you said ( we did this DIY before over this forum ) end. Where's it the post, did you remember? I want to understand more thanks men
