Re: acer nitro an515-43

Hi, I have a FH50Q LA-J621P Rev 1.0 motherboard.
When I turn on the laptop, looks fine , but no picture at all. I downloaded the bios bin and write in the bios chip(25lb64csig) but after I turn on only once give me the "ACER" logo but nothing else.

Re: acer nitro an515-43

When I first read the chip, it was empty. I using a TL866II plus programmer, and xgpro program. I attached a BIOS, what I used.

Re: acer nitro an515-43

Not working.(Turning on but no picture), is it possible because of the programmer not verifying the writing and cause the problem? How can I solve that problem?

Clean the solder from the pins using some flux and braid,and make sure the pins all line up in or on the socket or adapter.If you have a spring loaded adapter try pulling up at both sides with one hand and try programming again.If you still have the same errors then the chip is bad,replace with another.
