Emachine E442 black screen

[senchire]

Hello guys, got fa fresh new E442 (broken ofc). Symptoms are sadly press power switch no screen, all led working (USB port's not working), and external monitor also no post. In there we have AMD V140 and ATI IGP4250.
Ram tested working fine. My next shot would be either CPU or IGP/NB.
I got the equipment to reflow or reball, sadly i got no CPU to test it to.
No beeps coming from it if i remove the RAM nor any light indicators for faulty or missing components are Emachine usually so(first emachine i have to deal with). Anyone faced same problems let me know .

could be the ATI IGP4250 is the problem, reball it, refolw won't work (red glue under the chip)

Re: Emachine E442 black screen

It had no red glue, it had lets say black dots. I removed them but had no time to reflow it.

Re: Emachine E442 black screen

yeah, there's some under the chip too, remove them also before you reflow it, otherwise you're just wastin time reflowin it.

Did the cleaning already, and before i wanted to reflow i noticed something on my micro. Well i saw "2 balls" fused together, i will tomorrow reball it. Was pure luck that i noticed that crapy thing, so that i don't waste time reflowing it. Will report back did that fix the problem (probably will).
