lg42lv5500 No picture but standby and power on light

I got a lg42lv5500 which has a red standby light and when turn on with remote or hard key it turns white and clicks but no picture.

I tried with a flashlight but can't see nothing, I found some. corrosion and cleaned it, did the heatgun on the main chip as well as it seems to be a common issue but didn't fix it. The main board this model uses EAX64104703(1) I have a main board from a 47" version of this tv and the board looks exactly the same, however the model number is EAX64405401(0) I swapped it and the issue is exactly the same, red standby light then white when turn on the tv.

Does anybody know if these boards are interchangble? Don't really want to buy a 3rd one if the main board is not the problem
