Screen blacked out completely

[Chris G]

Hi,

It sounds like the display ribbon has come loose or the display has suffered some kind of hardware failure of sorts. Did you recently get it? contact your seller for support. If not, try and open it and see if the ribbon cable for the display is attached. But I only recommend removing the cover if you have done that sort of thing before otherwise leave it be and see if you can get it fixed.

Thank you for the quick response.

About contacting, I will try, though is a long shot, since I bought it from an ebay store. I live in Bolivia and ordered from china, also, in the “return policy” it states that it should be “unused – unopened package” (silly return product policy…). Yet I’ll try to contact, because if “ribbon check” fails, I guess next step will be to (save some bucks) order a replacement for the display.

On to the ribbon check: I did before replaced display and digitizer for an iphone, and also did see on the web some videos on opening the teclas tablets. I must say, after the “blackout” and many tries of rebooting, I did manage to take off the cover, but found many kind of isolating tapes or a kind of fabric protection over most of the conectors for all the ribbons. So I steped back from touching stuff, since I don’t know exactly which to check. But if someone would be so kind to share a video, or a sequence of photos (since it is hard to even find diagrams of the insides of the teclast devices on the web) indicating what is what inside, I could give it a try.

I’m also thinking of taking it to some technician in town, but in my xp, many times the are just as “youtube qualified” as I am, and many times they break-pry phones before checkin on the actual way of uncovering them, or even looking for screws, so I am not that sure about taking my tablet to some self-proclaimed expert (…maybe yes on blockbuster popular devices like samsungs or so…).

Any forth help on understanding the insides of the tablet is welcome, as well as any considerations to keep things safe (beyond what is known about forcing things off, electrostatic discharges and those things).

Also, I’m very new to the forum and I don’t know if there is a way to upload videos displaying anything that could help on… helping me; and my english might be a little lousy, so I apologize for that.

Thanks again for the help.

You are living in Bolivia, so i guess you can speak Spanish.

Here  you have a video for changing the display screen.

I don’t know why this forum is inserting me this crap of tags.

Sorry about that…

Thanks for the link. I’ll check on the ribons, then report back….

Maybe it’s not a HW problem, because you wrote ” it does connects, but even at the remote station is just a blank screen”, so it’s more like a BIOS bug, since TeamViewer also displays a blank screen. If the display’s connection would be loose or broken, you would still be able to use your tablet via TV.

Have a nice day, y'all!

Thanks to everybody contributing and answering. The probblem is fixed: a ribon from the display (push lock-like, not lever lock) was badly plugged. Most of conections came under some security seal tape (I’ll edit and atach photos in a while), and it was not that obvious.

Thanks to youtube video submitted by CpA I learned which is the display ribon, and tracked conections. Then (before replacing cover), tried to turn on and EUREKA!!!, back to OS menu, back to Android, and back to Windows. Good bye glitches on picture.

To StormChild: thanks for interest in helping. It seems I wrote ambiguous things. I meant: TeamViewer logged (screen still not working) – dunno if this clears things up, haha, but anyways: I have thought of pluging a display, but I didn’t (yet) get the mini … micro…. nano…. dunno…. HDMI cable or adapter for it so I couldn’t try that. But I figured (in my mind…stealing my sleep some couple of nights)

“if the display hardware unpluged, and Windows doesn’t detects any phisical display…. it may not render any picture at all, not even for the remote session… teamviewer is not added as a virtual screen anyway”

Maybe if I could have found a hay to plug an external display, I could have seen everithing else working normal … maybe touch screen not, but everything else yes. Leading me to same conclussion: Display is disconected or busted.

Thank good God display seems to be working just fine, and thanks to the forum and you guys who helped me in my hour of need.
