TC1100 checkered screen

Hey Blaino, I interested in getting a tc1100 repaired with the infamous checkered screen syndrome. Now it will only boot in safe mode and the checkered screen is there to stay. Not sure exactly how to go about fixing it; cables or system board. I don't know where I might be able to find a replacement system board. Can you offer any advice on this or maybe even repair my tc1100 for a fee?

Thanks very much for your time.

    • When I got my TC1100 I thought it was the world's most perfect PC answer. Approximately 2 months after I received it the pc began to overheat and the screen began to flicker. I ignored it thinking it was a new computer issue - this issue did go away. However, after about 6 months the sytem began to overheat again, so I began to use it less. Months later the screen began to blink a black and red checkered pattern sometimes. The problem would clear up if i let it sit unplugged for a while. When it no longer responded and I called HP Tech Support is was exactly one month after my warranty expired, and it would cost at least $100 just to have them agree to look at it. In one of my attempts to get the computer to cooperate I managed to wipe part of the operating system, so now I need to have the system checked and the operating system restored. Any suggestions?

Could be a bad ram chip as video uses the system board ram for video. You will have to crack the case and swap the ram for a known good stick. Be very careful!
Unfortunately the onboard video card may be bad, usually the problem.
I could crack it and check it for you, you pay shipping. I have the RAM.
Contact me at with "TC1100 repair" in the subject line.
I love the machine and you shouldn't have to pay a fortune to get an opinion.
I don't offer this service to any other group, machine or etc. Just the tc1000 and tc1100.
I'll answer your email and suppl contact info. I've been into several of these machines, no worries Mate.

    Unfortunately Fellow TC User, the problem relies in the Keyboard port area whereas when u use the tablet with the keyboard, it somehow creates a hairline crack in the gpu area, which gives off that corrupt look. i found a light fix that you could use, with the ext. keyboard connected to that port, flip it into laptop mode and lightly pull back while turning the tablet on. In doing this, it aligns the crack just enough to let the bridge to recognize the gpu as OK, thus removing your checkered screen and allowing windows to detect it as a regular gpu. If it fails, slightly back more while turning on, but not too hard as it could crack the keyboard frame (thts how i lost my keyboard :/)

I have upgraded my tc1100 to 1.5Gs of memory. The description on the memory module is ( Super * Talent D400SBG/H STT DDR-400 PC3200 SO-DIMM Hynix 1G/64X8). The problem is the computer initially boots into...

It sounds like that memory should be compatible with your tablet PC. It may be a bad memory stick -- try to replace it with a different memory stick (preferably from a different manufacturer) and see if it still gives you the same problem.
If you didn't have this problem before you installed the new memory, a different memory stick will likely correct the issue. You can also try removing the new memory and see if the PC boots up like it should.

Can the touch screen or video card on a HP TC1100 be upgraded?

Hi, well I have found out that NO you cannot "Upgrade" either the screen, or the Video card. This is due to the BIOS, not being able to be upgraded to allow for this to happen. And HP do NOT support anything like this either :(

Tc1100 Blank Screen

You have identified your problem/fault by plugging in an external monitor and the image is OK. This proves the video card is OK and the fault could be the inverter or most likely the CCFL lamp.
The flickering screen indicated the CCFL lamp is faulty, it is a mini fluro tube which provides the back-light to the LCD. The inverter supplies high voltage to the CCFL lamp. It could be faulty and it is easier to replace.

TC1100 onscreen keyboard.

Use a USB keyboard and do a system restore.
Use a USB keyboard to access and search for a download there.
Use a USB keyboard to backup, reformat, reinstall factory image.Takes longer, but probably best overall fix, HDD may have a few bad sectors and format will fix or avoid them. May be a great time for a 7200 RPM drive and some more RAM! 2Gb RAM and a high speed drive will breathe a bunch of life into a great tablet like the tc1100.

Chequered screen

I fixed mine finally!!! I ordered a cable kit and replaced the cable from the display to the motherboard (I actualy replaced them all but that one was the culprit.) Also, I learned that if you put the cable in backwards :) into the motherboard, it will appear very dim as it did with the bad cable. I believe that this is because the backlight inverter is not active, which in other posts here, may mean that the inverter is bad. Just a thought...
