My MacBook don't turn on, only get Beep every 5 sec interval
Hello, help me please!
A few days ago I bought a used MacBook Pro 13" (mid 2010).
On the second day I used my Mac too heavily, so it led to overheating. I closed lid, put Mac on the table and after 20 min I returned and tried to start it. But it didn't turn on. There wasn't a start signal and the screen was dark, only a beep with an interval 5 sec.
On the next day I turned on my Mac without problems, but after work I closed lid and the problem repeated itself.
Sometimes after I can start the Mac without problems, but at the last time it completely stopped. And now I'm getting a beep with an interval 5 sec again.
I tried to reset NVRAM & SMC, but without any effect.
I dismantled Mac and my opinion the problem is the video card is damaged because of overheating. So I want to try solder video card.
So, what is your opinion of this problem? Am I right, that problem in video card?
And please, can you tell me:
Did they use lead free or lead solder on these MacBooks?
Can you tell me solder temperature?
I will be grateful for the answer
I forget to add, there is no problem with the RAM as I tried a different set of modules,
I also tried to clean socket, but no effect, so I suggested, that problem in other component.
Ist dies eine gute Frage?
