Did you do the flashlight test?
Also, it's nearly impossible to get the drivers installed without a good display. But if you had a LINUX system many of those just work with USB video cards and not such a big deal.
I'd sell it off for parts and never look back.
I personally HATE all-in-one PCs due to scenarios like I am about to describe. I have a customer bring me an HP AIO that won't turn on. Anyway, I diagnosed the unit and it is turning on. Here is the problem. You hit the power button and it turns on and boots up with a chime and everything. There is no output to the screen and there are no HDMI ports on the unit.
Anytway, I opened the AIO up and it wasn't hard at all. It was only two screws which I have seen before but it isn't common, especially on a cheap unit like this one.
The power inverter/converter board for the LED was smoked. Components were melted and blackened so I knew it was at least part of the problem. I blindly ordered and replaced this part as it was only $7 and I was willing to gamble that much money. Nothing was solved. It still turns on and boots with no display. I assume that the circuitry on the motherboard or the LED backlights themselves were fried by the incident.
Anyway, the owner has since replaced the unit and gave it to me to recycle or whatever so I wanted to play with it a little before sending it to the recyclers and see if there was any way to get a working display in this unit for cheap.
It has been suggested that I use a USB video adapter. The problem is that I assume drivers will need to be loaded for this to work and I have no display and no way to load the drivers so that is likely out. Anyone have a way to make this work.
The other possibility is to splice the harness into a laptop or desktop display. I assume the output it digital and not analog but don't know.
It is an HP 23-g013w if that helps. I know the W means it came from Wal-Mart and this is what you expect. Again, this is a low-end unit so I don't want to spend a lot of money to tinker but it is at least a Haswell Pentium Dual Core which might have some interesting potential. I could mount it in a slimline case with a laptop display mounted to the outside of the unit. I might see if the pinout looks similar. Then there is the issue of powering the backlight.
