Question about Toshiba Tecra M4 Notebook
Since a few days my Tecra M4 started to have this color problems, too.
It started on a warm day, while rendering a video. Additional the battery had been empty and were charged at that time. So it became pretty hot (processor and HDD under heavy workload + charging battery)
It all started with the black going red, a certain blue going violet and some ghost line flimmering. I switched off the tablet PC and let it cool down. Later it worked fine again ... but not for long. Now on boot-up often the boot screen is red were it should be black, too. So this is no graphic driver issue.
When the text at boot-up is readable (even when black is red) WinXP boots without further problems. If the text is not readable the WinXP bootloader screen has blue vertical lines and before XP can be started I get a "page_fault_in_nonpaged_area" 0x00000050 error and it reboots. Sometimes everything get fine after a few reboots, but sometimes everything is black and the VGA fan runs at maximum speed.
Under XP I used GPU-Z and PCWizzard to read out some sensors. The NVidia chip gets up to 88° C, but the fan does not turn. If it runs temp goes down to 60°C. If the fan does not run, the items for GPU temp diode and fan speed are missing.
I read on the net that due to the high temp the GPU most likely got loose, but it is not possible to fix it but cause it has to be soldered in a stove. Workaround should be to put a piece of cork between case an GPU cooler. Has anybody a pic where exactly and in which dimensions?
BTW, when I lift the right rear corner or push down the left rear corner a little bit everything is fine, too (sometimes). It seems not to happen in battery mode since the GPU does not run with 300MHz then....
THis happened to my Tecra M4 4 times in 4 years. Each time was a motherboard replacement at the tech repair shop. Each time cosint about $600. I have heard of the heating method to reflow the solder but don't know how to do it. Others have paid for the motherboard replacement and modded the GPU fan to constantly run. I may get it fixed once more and try using a laptop cooler to keep it from overheating again. Because it is soldered on to the motherboard, they replace the entire board.

Testimonial: "Thanx for the feedback! Yeah that's what I heard too or at ebay solder fix for 150 Euro. The fan I used all the time didn't prevent mine issue. "
Do to your tecra m4 what the guy in the video below did to his hp tx1000 - it worked for me for both laptops

Sounds like a bad video inverter.If it was the video card it would probably show on video at all,even if the thermal grease had thinned or liquified to run.You may have a combination of problems which will probably result in a faulty motherboard or a heat effected video card failure.
