asked

I have an HP Touchsmart IQ526T PC with a touchscreen. The screen won't turn on, but it makes the correct sounds when touched, and the computer portion seems to be working as the fans and power lights come on. I measured the voltages going into the inverter and they are steady at 4.95 and 19.50 volts. I also noticed a momentary white flash on the screen and a blue LED light when I unplug and replug the power adaptor. I suspect the inverter might be faulty. Can I get technical assistance to diagnose and correct this problem with my HP Touchsmart PC?
