HP touchsmart tx2 display problems at start up

[dominusnex]

Well I just typed a long detailed message here only to get a error on the forum and lose it SO to sum it up here's what happens to mine.

I've had it for about 6 months and have been randomly having this issue for a couple months. Happens at POST and goes back to normal in windows or vice-versa sometimes. Same if it goes to sleep when it wakes up in windows it may do it but I can navigate blind and drop the res to 800x600 to fix it and then pop it back to the regular resolution. Top portion shows video, bottom 2 sections are always black.

I called tech support, sent it in, got it back and it had the same issue the second I booted it for the first time.

I called tech support again (got India or something) they said it was an AD issue (accidental damage) and I'm not covered. They claimed that "I" must have damaged it in direct sunlight, dropping it or covering the vents. I assured them it wasn't the case, spoke w/a supervisor who tried telling me it couldn't be a cable or inverter and that at POST it doesn't go thru the GPU so it MUST be AD - not covered under warranty.

I called back, got Canadian support - They said it definitely needs to be sent back in and is most likely a GPU issue.

So, tomorrow it goes back to HP (they need to send a whole new box, can't just provide a label via email)

We'll see what happens this time.

FYI: For those interested they replaced the display this first time.

Well I havent sent back mine, but i have received a box to send it back, im currently waiting to finish my trimester this week and ill be sending mine. I have been using the heat up and turn off monitor and turn on again.  One thing i have noticed is that my computer came with one of the hook things that make the screen stay still when closed or in tablet mode defective making my screen wobble when i write down sometimes and has resulted in wearing of the corners of the inside and outside of the laptop. So im hoping they can fix that too. And its definitely a hardware issue dont worry cause i have a friend that had the same issue and he didnt buy it off of amazon like me, but from best buy.

My Friends,

I updated the BIOS but the problem still remains. Has anyone got a definitive solution and concrete on the subject?

[IrvingQuester]

Yes there is a workaround and yes sir I found it...

Don't turn off the computer during the night... Keep the computer always on , let it go in sleep mode only for few hours...

More seriiously, it's worsening. I am sending it back for repair.

I didn't find any serious workaround and it is hardware related...

UPDATE:

Sent my laptop back to HP for it's second service since it had the same issue on the first boot when I got it back before.

Apparently they did the same thing and replaced the display and 'so far' I haven't had this issue... IF it is solved then they have plenty of defective screens out there, including those they're using to replace screens with when sent in for service.

Finaly I have resolved this problem by this way:I open LCD and disconnected all connection to separate it from notebook base and then open lcd cover and removed the rear cover you should be very carefull.and then remove the transparent cover from lcd pcb never remove stick arround the lcd that marked with red warning. .under that cover there is a aluminum stick that covers a part of pcb.that pcb area is golden metalized. if you remove and then replce it with your finger force it will be resolve.I think the glue under aluminum cover prevents the good contact between aluminum and golden metalized area of pcb and after somtimes it collects some electrostatic particles and they are preventing good functinality of lcd.so with this

I think that this solution is not possible for everyone experiencing the problem since it will cancel the warranty.

I sent it back and HP will repair it.

Good luck everyone.

I also have the exact problem, can some advise what to do

[dominusnex]

I'd recommend anyone with warranty still send the unit in for service - if you open it up (as previously suggested by another user) you will not only void your warranty but you could also damage additional components.

I am having the same problem, It is frustrated, I will never buy a HP computer again, it is not worth it
