and welcome to our forums
1 Sorry to hear about the problems with your HP AIO..... not having any visible output makes repair very tricky as I guess you have discovered!
2 The fact that the AIO doen't normally ship with a VGA/DVI or even HDMI output makes things even more tricky.
3 However check that your particular model number doesn't have them as it sure would save some time if you could find any!
4 If you can't even see a BIOS screen then its not looking good, if you can see a BIOS screen then there is hope.
5 With the machine booted up wait a few minutes and then take a flashlight/torch and holding it at an angle of 45 degrees to the screen at a distance of 25mm from it, see if you can see a "ghostly image" of your normal stuff.....let us know if you can.
6 If your computer is still under guarantee/warranty service repair agreement, or if the consumer rights legislation in your country's jurisdiction gives you repair rights against the vendor, then this could prove a fruitful avenue to pursue.
7 In the workshop when faced with this sort of issue on an AIO without alternative outputs then we try and boot a live distro of Linux (running purely in RAM) but a good memory is essential (ours not the computer's!) as its necessary to visualise in the "minds eye" what should be appearing on the VDU and use the keyboard to move around the blank screens!!
8 Because step 7 above takes so long....consider the following.... its possible to buy a USB to VGA/DVI adapter with cable that enables an external VDU to be connected..... these can cost around £80 GBP or around $100 USD or so, ( some can be found cheaper) but rather than buy one see if you can borrow one as its not at all certain that this will work for you.
9 Some of the adapters need drivers installing, (they usually come with a CD before they will work so you will still be working blind to a certain extent, when you come to install them!
10 In extremis, we have pulled out the hard drive slaved it to another computer installed the adapter and copied the drivers to the slave hard drive and then replaced it in the original machine...
These thoughts are intended to be helpful but I would counsel against spending too much money or time on it as there is no guarantee of success and oftentimes the money is better put towards a new computer!
