TC1100 garbled display

Hi, i'm currently living in Indonesia, i had the same problem with my display.
HP doesn't have any support for my tablet, they can however order the part from somewhere else, singapore if i'm not mistaken.
And it's pretty expensive... so i was thinking of buying the part somewhere else and replace the board my self.
can you give me a tutorial on how to open my tc1100?
If i change it, will the same problem occurs again?

Got it!

1. It is a problem with the system board
2. The problem is with the soldering
3. We've pinpointed the problem to the video chip

There is a defect in the solder job on the video chip attached to the system board. The solution of applying pressure to the top of the chip solves the problem every time.

My suggestion is to place a 1" metal washer on top of the video chip. So that it does not move around, be sure to wedge one end of it under the black tape that covers half the video chip. Now re-attach the heatsink cover and bingo, problem solved AND your video chip is keeping cool.

Hope this solves your problem!

No Calibration for Wacom Pen

Sounds like your pen has problems, after so many attempts to calibrate the pen fail your tablet will automatically shut that feature off. I would suggest getting a new pen if possible and recalibrate it. The wire or fiber optic cable, which ever it has is bad to break where it bends down into the pen. Also the sensor in the end of the pen could have gone bad. I would contact the manafacturer on it and see what their tech's advise.

My Genius Easypen i405x cannot detect and sense pen pressure

I had the same problem. I have been using Win7. The solution is very simple: Uninstall your genius driver, restart your computer. Plug in the tablet, now the Windows should detect your tablet, wait a minute while the new drivers is installed. And from now it should work. Sorry for my English.

How do i reset my viewsonic g tablet to it's factory setting? currently, the message: The application Dashboard Home (process com.tapntap.home) has been stopped unexpectedly. Please try again, keeps...

Hi there,

If you can do anything with your tablet then try pressing menu on the home screen, and then go into your settings - privacy - factory data reset - reset tablet. Keep in mind that this will wipe EVERYTHING from your tablet. Any of your apps, contacts, etc will be erased.

Garbled video on tc1100

Sorry for the long reply, but I hope this helps.

You will need to replace the system board and the keyboard receiving bracket inside the computer to fix this problem.

I work at an institution that uses these laptops and we've seen this repair a lot... and I personally have a tc1100 that has gone through 5 system boards. HP has a new (slightly redesigned?) keyboard receiving bracket that helps (but doesnt always) remedy this problem. HP themselves told us that we need to replace the systemboard, keyboard bracket and keyboard when we see this problem on one of our machines. We replace them all the time at our repair shop and it is the only thing that consistently works.

Note: The system board's connections near the graphics controller can be severed (its a multilayered board so you might not be able to see it if you looked) when the keyboard can move inside the keyboard bracket thus causing your garbled / checkerboard screen.

For this reason, you can sometimes temporarily get it to boot correctly by tilting the screen towards you all the way before turning it on. We've also seen some cases where disconnecting the keyboard and trying to boot will work. You can use those ideas only as temporary fixes though, and I'm sorry to say that this problem will get progressively worse until you repair it.
