Buy a vga, dvi or hdmi cable depending on what your pc uses and plug it into a different monitor or tv. If this works, you can also purchase a wireless board and mouse and have it working on the tv

How i unlock password


Do you have access to another computer? You can use your Google account to remotely reset it.

There is also some not too expensive Apps that work.

I am having a hard time figuring out if there is a mechanical reset or not. I need to know more about the unit you have as IRULU has five different models of the 9" and most models come in 5 different varieties.

If there is a mechanical reset, sometimes it is volume push up and power, sometimes it is power/home button as the back/select button.

Below are some links you may find helpful also. I can help more if I know more about your tablet.

Hope to hear from you soon.

Replaced digitizer now black screen only


If the LCD was working before replacement, the most likely suspect is a loose cable connection. It is also easy to crimp those tiny flat cables, or to break the locking mechanism so the cable can work its way loose. Sounds like you booted to a black screen after repair, so I would walk back through it and double check every connection, then look at all cables closely in bright light and with a magnifying glass, to be sure nothing sustained damage (twist, crimp, etc.). Remember to check the power cable to the LCD, as well. No power, no backlight, no video.
