HP pavillion dv5-1010ev no picture

[lefos]

Hello!

This laptop powers on but doesn't have picture. It has an ati vga which I've changed with a new one but the problem still exists. I am wondering if anyone has any bios dump for this one please or any other suggestions?

manufacturer p/n DA0QT8MB6F0 rev f. hp part number : 482324-001

Thanks in advance.

reflow the chipset

Re: HP pavillion dv5-1010ev no picture

Thanks for your reply. If it is the small chipset then I have already done that. Do you think that it is worth to be changed?

Re: HP pavillion dv5-1010ev no picture

here are the two bios-es that are from hp website
i believe one is for board with dedicated gpu and other for onboard but i don't know which one. try each if u can
also i have found the cpu to have gone bad on this model ,also give a good alchool clean on ram and socket
but is more likely the rs780 chipset to be faulty.
good luck.

Thanks for the files sorinac. Well found out that the correct bios file is 30F2F38. Nothing changed after flashing the chip. I have seen that the scroll lock led is blinking 4 times. Been searching for self diagnosis but no result. Any ideas ?

Re: HP pavillion dv5-1010ev no picture

4 time = vga


1 time = cpu
2 time = bios damaged
3time = ram
4 = vga
5= system board
6= bad bios signature

Thanks for the info. The odd thing is that I have already changed the vga chipset with a new one..
I am thinking of giving the laptop back. I really don't like those hps..

I think your model has two ATI chips .
I guess if you change one that maybe you change wrong one !

Re: HP pavillion dv5-1010ev no picture

Thanks for your replies. I will try to change the small chipset and inform back.

If you don't get the HDD led blinking (system attempting to boot), it's the NB (small chipset) at fault. Don't need to replace, reballing will do.

Re: HP pavillion dv5-1010ev no picture

Hello,

Today I received the chipset and after the change it doesn't blink 4 times but just 1.
@dellxps are you sure that one blink is cpu fault? I have checked with other cpu but still the same..

[Th3_uN1Qu3]

Re: HP pavillion dv5-1010ev no picture

1 blink as in blinking continuously, or as in 1 blink and that's it? Reflash BIOS and see what it does.

Re: HP pavillion dv5-1010ev no picture

1 blink then again after 5-6 seconds .

[dellxps15]

Re: HP pavillion dv5-1010ev no picture

i think 4 blink = vga, while 1 blink is chipset, so maybe a chipset reballing has gone bad?

hard to say to that point....lets wait for other suggestion.

today i fixed a dv5 board and one mos from the cpu power rail was faulty.
check if you have 0.9v on cpu and if the cpu is getting hot

[lefos]

Re: HP pavillion dv5-1010ev no picture

Thanks guys for your time. @ sorinac cpu and gpu get both hot . Anyway I am giving the laptop back to its owner.
