Re: Power supply no work, tv dead
Forget the previous message, this is the scheme and has a U49 IC that is the one that provides 3V3. In the input has 5 volts but no output....Leave a comment:

Re: Power supply no work, tv dead
Hi, I suppose that PSU don´t generate 3v3. In the motherboard I has a (i suppose) a FET marked as U21 where in a pin has 5 volts and in output has 3V3 but but but this voltaje don´t arrives to MT5820.
I read continuity with multimeter and from ground to 3V3 line I has only 1 ohm... Possibly shortcut in 3V3 line. I lift the two 3V3 (power IC) legs from MT5820 to check if the shortcut comes from this IC but no, the IC is not in short cut... I think the trouble can be another component that prevent to 3V3 arrive to all...Leave a comment:

Re: Power supply no work, tv dead
Hi, then my mainboard is dead and the PSU is OK?
Can I change only the CPU of the mainboard?
I diassembled the main board and has a thermal rubber from solder side to the screen plate.Last edited by neodark; 07-17-2016, 03:26 PM.Leave a comment:

Hi, yes, all the capacitors has voltaje, some 12 volts and some 24 volts.
It´s very strange......Leave a comment:

Power supply no work, tv dead
Hi, I has a TV that has power supply 17IPS19-4 and the TV no led power, only the power supply has a noise, the small square yellow coil from the first pic has a noise (on the first pic, right-medium side).
All de diodes are OK, with the tester in direct measure has about 240 measure and indirect test infinite.
The capacitors has their correspondient voltage (12 volts and 24 volts) and I don´t know how to continue procced.
The burned part on the first pic is for heat solder, no component burned.
Can anyone help me?
Thanks!!... -
