no it's not fried, it still works as before...the heating is meant to re-activate the chipset...i tried another monitor on it but not external...i'll try to connect external today and see what happens

thanks for the reply

i have a hpv9000that doesn't display ,it belongs to a friend ,they left it running on the bed overnight !
on screen and i have done some research about gently heating the chip with a torch to re-solder the chips on top of the video card,,but all i read same the same thing ,using a small torch gently heat around the chip to 210 deg ,a long way from your almost 400 deg .

Oh! this system is not new, it is the only way of getting the vga chip back to life again...there's this small heat machine that is specifically designed for that purpose...i'll try to get the name and post it later. i have beeing using this method for almost 4years now but it has often failed when it comes to IBM series...don't know why IBM is so complex
