Changhong LCD32350R no display

[yobbgsm]

Hi Mates,

Here I am again, soliciting your knowledge in electronics. So I am new in LED/LCD repair but I found it interesting, it was so fascinating how it works and how circuits travel to turn on the TV

This Changhong LCD TV 32' has no power when arrived. I troubleshot the circuit and found out two mosfet is causing the fuse to blow. So I replaced the mosfet and the fuse, I t got power with standby mode then green on lights but no display, I think there is still something wrong with the couple of components but I have a limited know-how yet how to trace and fix the circuit.

I have here attached the power supply, measuring the DC part of it, I have no voltage in two 5V and two 12V, that is going to the mainboard. I know that's the issue I just don't know what component is responsible to provide the voltage. Your help is very much appreciated.

hi guys,

JUST AN UPDATE. I found something strange on this components attach. Looks deformed and damaged. I think I found the culprit but don't know where to get the parts.

that might be a hard one to work out, unless someone has one around at the moment.

I think u4 & maybe u3 are also damaged, along with q23 R84a and I doubt the optocoupler survived
