Question about HP PL4272N 42 in. HDTV Plasma Television
When I connect the power cord to the TV it automatically turns on and goes directly into a green testing screen that assures me there is no problem and then tells me to power down the TV and check the connects. The remote is not responsive and neither are any of the buttons on the TV itself. Please help.

You can try resetting the printer.
Step 1. Unplug the power cord at the back of the printer while the printer is still on
Step 2. Press and hold the # and 6 button on the printer while the power cord is disconnected. And keep holdig the two buttons until you plug in the power back again.
Note : do not release the # and 6 when you plug the power cord back in. keep holding the two buttons until the printer would turn on then turn off or the printer would say anything about "reset"
Step 3. Try sending a fax after the successful reset of the printer

You could have a defective screen - a defective inverter or a CCFL lamp or simply the video cable needs reseating. After reseating the video cable and the problem is still there then :-
To determine if you have a LCD screen or video card problem, read this and follow the instructions.
Defective CCFL backlight, it may have the following symptom:
Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.
Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.
