HP Pavilion TX1000 no boot issue - Oven fix!

Do you have a HP Pavilion tx1000 laptop with a no post issue?
If you get the symptons, boots up (blue lights activate) but no image on the screen, this may be the solution!

1. Start by stripping the machine down. Take all the covers off the bottom of the machine and remove the hard drive, memory and all screws from the base.
2. Remove the LCD digitiser and the other connectors from the motherboard.
   
3. Remove the keyboard by genlty prising it out.
4. You can now access the screws holding the LCD module on. Remove these and the swivel unit should now be free.
5. Remove further screws from the keyboard area and the top cover should now gently prise off (remember to disconnect all wires from the area)
6. The motherboard should now be accessible and come free when the powerbutton and all other connected PCB's are removed.
7. When the board is free, remove the heatsink/fan, bluetooth module (if installed) and CPU.
8. Remove all 'meltable' items from the board (such as the foam LED covers for caps lock and power indicators)

Right, now for the strange part!

The no post issue is common problem for most of the HP DV range. The VGA chip on the board becomes defective.

The way i fixed this TX1000 was to 'reflow' the VGA chip using a conventional oven (excuse the pun).

Place the motherboard (minus the plastic attributes) on a baking tray and place in an oven for 6-7 minutes then turning the board over, for another 6-7 minutes.

When the board has cooled down, carefully reassemble the machine (not forgetting the plastic shields). If all has gone well, the unit should power up and actually post!

Please post comments on whether this worked for you, hopefully, you've just saved a few pennies!
