Hi everyone,

I have the following problem, see photo how i test the motherboard.
Adapter start with green light and goes to orange and the fans are running directly and goes to high speed.
I have measure a lot of points but , i don't know where the problem is. No chime and no display. Backlight is well on the screen .
I think it is an heating problem but which components and where to look?
I bought this macbook pro and it was with a cracked screen. I replaced the lcd but no screen only backlight.

Can somebody help me or give some hints to look further

Have you tried an external monitor?

If it didn't chime before buying, is it possible the speakers or speaker connection on the logic board is defective?

Was the MacBook ever exposed to liquid? Fans running at full speed may be an indication of liquid exposure. I've had this happen with MacBook Airs I purchased for parts.

Is it possible to perform an SMC reset?
 
When i buyed , also no external screen.
Some history ; it was delivered without harddisk and power supply
In the mean time , i bought a harddisk, an adapter and now i'am waiting for a new keyboard, trackpad and battery.
At this moment i'am not able todo a smc reset of other choses.
Is it normal that the power adapter starts with green light and goes to orange whitout a connection of a battery ?
[doublepost=1555254500][/doublepost]The motherboard is very clean, like new
 
The battery was difficult to leave out and also the keyboard and i would be certain . The lcd of the screen i replaced with succes , not broken but still it does't work. I want to fix this pc and hold it for me
 
Without seeing the boot screen, it's possible that there is an efi password too.

Yes, connecting the charger without a battery could have the magsafe LED change from green when first connected to orange when it does not detect a battery.

Does the MacBook turn on by itself after connecting the charger?

I tried but the USB keyboard is not a mac keyboard and with an usb mouse.
I think it is better to wait on the new spare parts and than we can go further.
 
The new keyboard and trackpad are installed, but only the backlight goes on and black screen
Test with HDMI to tv screen negatief, test with external screen by VGA adapter negatief ??
Start in diagnose mode negatief
Start with options key negatief
What van i do more ?
 
The keyboard backlight or display backlight comes on?

You are sure the display is working properly?

Did you try connecting a display port cable to the logic board?

Are you able to reset the SMC and NVRAM?

You are sure the speakers and keyboard are functional and correctly connected?

i don't know ? but no light on the keyboard, only the power button on the keyboard works , because i can power on and off
 
Sounds to me like you'll have to have the board examine by a repair technician that is able to perform board-level repairs if you are sure that everything you attached is working.
