asus X53E/board K53SD rev. 2.1/ self start need schematic

have this one asus X53E/board K53SD rev. 2.1/ and it self start and not fully reage to power switch. i ffind taha it have some short on main power on LVDS connector because i see some self-solder in connector.

cannot find schematic to fully diagnose it. any help with it?

board code is hannstar J MV-4 94V-01122 E89382

i found that it can have same board as acer 8942/8943

This you need to check?

Re: asus X53E/board K53SD rev. 2.1/ self start need schematic

maybe its simmilar but this asus have other ics and no board marks a and some ic are not the same


But i think i have some broken contact. when i twist the board in some direction it works normally. do somebody know what ic or part can have that loose contact? i dont wanna bake whole board when it works

sometimes it start without display with all leds come and restart, sometime it wont start but have all basic voltages, sometime it start ok. what do u think what ic can be doing this?

Re: asus X53E/board K53SD rev. 2.1/ self start need schematic

In the other thread, I have the Asus K53sv mobo, also no marks and no schematics.
I was hoping you were right about the Acer board.
The onliest loose contact item I would suspect is the power plug or direct related components.

I try to help were I can with schematics, I f you symbolize that with a trashcan, maybe I should not react anymore

Re: asus X53E/board K53SD rev. 2.1/ self start need schematic

now i 100% know its broken contact when i put little pressure on one corner of board it work, but whe i put out that pressure it restart. what ic it can be?/see picture/

[hansie55]

Re: asus X53E/board K53SD rev. 2.1/ self start need schematic

When you put the pressure, where is the board supported or held?
At the place it is supported there may be more components than around the pressure point.

Re: asus X53E/board K53SD rev. 2.1/ self start need schematic

the board laying on the table i think on the heatpipe on processor. but i think the NB can be that ic, because board do some funny thing like no video or no start when no twisting it.

when i dont find anything i try to reflow it.

Re: asus X53E/board K53SD rev. 2.1/ self start need schematic

This you need to check?

I need a schematic for a similar mobo hannstar mv-4 94v-0 of Asus K53SV but is for AMD processor, not for Intel like the pdf schematic appended here.
Have someone the correct one please? My Asus looks dead.

[ktmmotocross]

Re: asus X53E/board K53SD rev. 2.1/ self start need schematic

if it looks dead, just measure all big coils voltages and resistance to ground

Re: asus X53E/board K53SD rev. 2.1/ self start need schematic

KTM , seems you got some problem near the on off connector . i had one asus making this , a ROG computer , but also apllying a pressure on that corner will make pressure until almost half the board , even if its much less than in the corner but will affect several solders . chek carefully on macroscope for broken solder joints.

Re: asus X53E/board K53SD rev. 2.1/ self start need schematic

i was starting it with soldered switch because i have only board, but it was half a year back. reballing ic did the trick

SORRY, i was looking at a different board, the hannstar E89382 mv-4 94v-0 is for Intel processors I series, I3, I5, I7, but don't seem the schematic to match. Have someone a PCB layout drawing?
Thanks for your help.
