nitroshift Posted January 23, 2010 Posted January 23, 2010 Upon boot, keep hitting F8 key and choose VGA mode.
RYU81 Posted January 23, 2010 Author Posted January 23, 2010 not there any loading from HDD,also if exit from bios not there display logo.only way to working again with turn off laptop then turn on again.
puntoMX Posted January 23, 2010 Posted January 23, 2010 Is it a HP with nVidia chipset?About what laptop are we talking about any way?
jaclaz Posted January 23, 2010 Posted January 23, 2010 About what laptop are we talking about any way?I would guess we are talking about RYU81's one... jaclaz

jaclaz Posted January 25, 2010 Posted January 25, 2010 Some Toshiba's (cannot say if that model) do suffer from a problem of connection between motherboard/videocard and display (the cable is simply a slightly bit too short and can make a loose contact).Can you try with an external VGA display and see if it behaves the same?Usually all it is needed is to remove the little cover between keyboard and scrren hinges and take out/re-seat connector:http://www.paulstravelpictures.com/Toshiba...uide/index.htmlhttp://www.paulstravelpictures.com/Toshiba...-Guide-042.htmlhttp://www.paulstravelpictures.com/Toshiba...-Guide-043.html http://www.paulstravelpictures.com/Toshiba...-Guide-044.htmlhttp://www.tomshardware.co.uk/forum/53660-...re-repair-guideAlso sometimes the microswitch that turns screen on/off gets stuck.jaclaz

jaclaz Posted January 26, 2010 Posted January 26, 2010 what about microswitch,it there way to fix it?It's a simple one way switch, you either try WD-40 or a similar contact cleaner or you simply connect the two pins to which the microswitch is connected on the motherboard with a loop of wire.But it should not affect external displey.Cannot say more without a better description of what is happening, but it does smell like a "real" hardware problem (fried videocard).jaclaz
Ponch Posted January 26, 2010 Posted January 26, 2010 only way to working again with turn off laptop then turn on again.though this would mean it's not totally fried. If I understand well, it sometimes works (or do you mean the monitor goes live again but only to BIOS ?)
RYU81 Posted January 27, 2010 Author Posted January 27, 2010 ok,I fixed it with using heatgun for GPU.
jaclaz Posted January 27, 2010 Posted January 27, 2010 ok,I fixed it with using heatgun for GPU.DYI reballing!? Welcome to the club. jaclaz
