Touch screen has gone black

Printer works great when triggered from the computer,
but the touch screen has gone to black, permanently.
No matter how much i press,it stays black.
I've unplugged and replugged.
Downloaded a new driver which allows me to trigger the scan from the computer,
but i can't get to the fax.
Is this a driver issue, a hardware issue...? Not sure what firmware is.
This question was solved.

Hi @lenny15,
Thank you for visiting the HP Support Forums! I understand the touchscreen on your HP Photosmart 7515 is completely black, you are able to print from the computer but cannot access the front control panel.
I would like you to perform a Hard Reset on the PS 7515:
1. Unplug all cables and memory cards from the printer. Unplug the power cord, directly from the back of the printer while the printer is still turned on.
2. Unplug the other end of the cord from the power source.
3. If there is a power module on the power cord, disconnect one end and reconnect it.
4. After 60 seconds, plug the cord directly into a wall outlet (not a surge protector or battery backup as they can cause the printer to lose basic functionality over time).
5. Plug the power cord into the back of the printer.
6. The printer should automatically power back up. If it doesn't, turn it on with the power button.
7. Try making a photocopy (if your printer is an all-in-on printer) before connecting any other cables to the printer.
8. Connect any other needed cables to the printer.
If after the hard reset you are still not able to access the control panel, I suggest you call our technical support at 800-474-6836.

My ipad screen has gone black but I can still touch the screen and unlock it and do things. I don't know what's wrong can someone help

My ipad screen has gone black and I don't know what to do the screen still works and I can still unlock it and I can still type. But I don't know what to do can anyone help me it will be much appreciated

If the reset doesn't do it then it's possible that the backlight or another part of your screen has broken. Unfortunately it's not really user servicible. I'd make an appointment at your local apple store and have them check it out. If your device is still under warranty and they don't determine that the damage was the result of 'abuse or neglect' (their words) then it could be a free replacement.
I'd just do a backup before you take it in, just in case.

My iPad screen has gone black. I have tried resetting it with the sleep and home buttons and it only flashes the apple on the screen for a nano second and then it goes black again. I can even hear notifications arriving, but I cannot see anything...

My iPad screen has gone black. I have tried resetting it with the sleep and home buttons and it only flashes the apple on the screen for a nano second and then it goes black again. I can even hear notifications arriving, but I cannot see anything...I'd rather not reset it to the factory settings as I have a lot of things I worry about using. Either way seems to me that the system itself is working since I can hear it working, but its the screen that isn't. It has not been dropped and has been in a case for years! Please help!

When the power is on and I press the home button, I can slide my finger where the slider bar "would be" and it makes the noise as if its "opening" flashes a blue screen then returns black...

My ipad 2 screen has gone black

My ipad 2 screen has gone black. The only thing that shows is the circular processing icon. I have tried turning it off and on and it won't even do that. Any ideas? Thank you!

Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

HT1212 I'm trying to backup my iPhone and restore it because the screen has gone black. It won't allow me to do anything without putting in the passcode. I can't put in the passcode because the screen is black.

Try rebooting it (hold home and power together for 15-20 seconds). If the display doesn't come back to life, you're out of luck. You're supposed to back it up before it fails. It's too late to do so after the fact.

My ipod touch screen has gone white with bright white spots, I have restored it but it is still white. It shows in ITunes but I cant do anything with it. Can anyone help please

My Ipod touch screen has gone white with bright white spots on it. I have restored it and it shows in ITunes but the screen is still white. Is there anything I can do? The warranty has run out so I will have to pay for any repairs (if it can be repaired). Any help would be much appreciated. Thank you in advance.

If you still have problems after restoring the iPod to factory defaults/new iPod then you very likely have a hardware problem. I would make an appointment at the Genius Bar of an Apple store.

If this is a Verizon iPhone 4, there is no SIM slot.
For non-Verizon iPhone 4, the SIM is on the right side.
Push a paperclip inbto the hole to eject the SIM tray.

Try a reset. Hold down the Sleep/Wake button + Home button for around 10 seconds until the Apple logo appears.
Let me know if this helps.

I have tried force quit- home screen and top button. iTunes is not recognizing phone when I plug into computer. help pls

FIRST charge with an Apple charger for at least 15 minutes. Then hold the HOME and SLEEP buttons at the same time until an Apple logo appears. Hold for up to 30 seconds. If nothing happens the phone hardware has failed.

TV screen has gone black

The TV screen has gone blank, we were watching it and changed the channel and since then it has remained blank with no sound. It is still working as we can get all the menus up and can change channels but the screen remains black.
We've tried restarting the BT box but there's no change, we've tried re-scanning the channels but again no change.
Please help!

Hi Jen_S, welcome to the BT forum!
You may be receiving a low freeview signal, if you have a booster fitted please ensure it is still switched on. Also could you please try removing the aerial from RF IN and rescanning, this will clear your channel list and allow a fresh scan. Once done, reconnect the aerial and rescan again. This should resolve the issue. If not can you let me know if you're receiving all channels you normally would.
Thanks,
