Much as I may sympathize with your TX1000 problem (a VERY common problem in that tablet PC that HP never acknowledged), can you at least have the decency to create your own topic instead of bumping a 2-year-old topic not even related to your issue? Laughing

Actually, I take that back, it rather is. The issue with the TX1000 is that the graphics controller (or the GPU-integrated northbridge, I forget) is poorly designed and broke contact off the board via overheating. You're pretty much hosed aside from having the chip reflowed by a board repair setup (check eBay). Or raising a stink with HP for their ridiculously poor design and lack of support.

See, HP acknowledged an issue with the DV-series laptops with the same issue. They had the same failing chips in them, and HP issued a warranty extension for those (I believe 1 year past the original warranty expired), but the TX1000 wasn't included in the extension, even though it has the same problem.

It's a great little computer - cooling is a little poorly designed (hence why yours failed), but otherwise a great system. I've had the opportunity to "resurrect" a failed TX1000 before, but it died not 2 days later (before it even got out of the shop). Hope you can get yours working again! Smile

OK. Its an adm turion laptop with a sis chipset. There is nothing wrong with the motherboard. The problem is in the chipset. The flashes mean that some of the solder balls under the sis chipset is damaged. The solution is very simple. If you have a hot air gun or a simle home hair dryer you can fix it.

first take the laptop apart all the way to the bare motherboard.
locate the main chipset.
take a piece of aluminium tin foil and wrap the motherboard - it helps dispence the heat.
take a knife and cut out the tin foil in a square where the chipset is located.
take the hair dryer or if you have a hot air gun set it to 330 degrees celzius and air flow to 5.
heat the chipset for about 3 minutes making slow passes over the chipset.
do not hold the air gun on one place long because you will damage the chipset.
after heating it let it air cool for about 10-15 minutes.
Plug everything back in and turn on the laptop. it should work just fine.
if you get the same problem again repeat the procedure.
For better thermal conductivity be sure to apply thermal paste on the cpu the main chipset and the vga chipset and you can use an extra copper plate.

THIS IS A RULE FOR ALMOST ALL LAPTOPS THAT HAVE A AMD TURION CPU, SIS CHIPSET AND AN NVIDIA VGA. IF YOUR LAPTOP TURNS ON BUT THERE IS NO PICTURE THIS IS ALSO THE SOLUTION ONLY APPLIED TO THE VGA CHIPSET - NVIDIA OR ATI OR SIS.

HOPE THIS HELPS.
