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

Hi if you talk about those around here i already test it there are good . Thanks

Yes, what are you listening to, without the T-CON connected, the mosfet also heats up and burns out?, look for a problem on the T-CON, what could be shorting it out.

Hi i just finished to look at t-con board it seems that most capacitor are shorted. I put one leg on the ground and meter gives me sound on bot side.. Maybe is better to find another one ..

Which ones are these?

for which reason the T-CON had one Fuse for 12VCC ,, are this Fuse dummy !!!. if you are talking on short you have on T-CON... use 2 batteries 1.5V so u have 3 V will low current and fed the Fuse with + and the - to t-CON chassis let see if this 3V will die ..

Hi do you mean right here injection 3v right here, and measured on the t-con 3v test point ? Thanks

Do you have a laboratory power supply?

yes you have point on this rail u can use it. and see the F on both side if there 3V

about laboratory power supply, can be used after the 3V test ok... then you can increase

Yes i have this one maximum 30v

Ok so for start 3v and with amp? I have thermal camera also, to see if any component getting hot(it could be a short right)

[lotas]

Apply 8 - 10 volts to these points and increasing the amperes, see what starts to heat up...

Hi I'm already doing what you say , first when I plugged in the camble, it going a little spark then the power supply going on protection (suppose short) then it seems that chip and a diode . Thank you

Guys I replace the new t-con and notting happened, no image only led on. So I'm guessing those components are similar or not? Thanks a lot

Doesn't matter guys. I will buy another main board and solve this night mare. Thanks for your time
