Having problems with your Flat Panel Televisions ?

I have a Sharp Aquos 40E67UN. We came home yesterday and although the TV turns on and our directv box turns on, the tv just has a blank screen where you can go to different inputs, but none of the hdmi inputs work. I also tried hooking in my DVD player via 2 different hdmi cords to make sure that it was the direct tv box that was the issue, but the DVD wouldn't work either....just a blank tv screen (but its on). Any ideas on what could be wrong? I can change the channels, the remote is still



Answers :

It's possible that you have a faulty component on one of the circuit boards inside your tv.
\015\012
\015\012It sounds like your backlight is working OK since the screen is lit up despite having no video so the fault is either with the MAIN BOARD, the POWER SUPPLY BOARD, or the LCD CONTROLLER BOARD (otherwise known as the TCON BOARD).
\015\012
\015\012Does the sound work properly for any of the inputs or is that blank as well?
\015\012
\015\012Was there a power failure or brief power flicker that you noticed at your home recently?
\015\012These can precipitate failures as the LCD TVs are succeptible to power fluctuations.
\015\012
\015\012Is your TV still under warranty?
\015\012
\015\012Are you willing and capable to unscrew and open up the case to the tv to conduct a visual inspection and some basic troubleshooting?
\015\012
\015\012One asy thing you can try before starting the hardware / circuit board troubleshooting is to unplug the power cable to your set and leave it out overnight. Plug it back in the next day and try turning it on again to see if the fault was cleared by the reset.
\015\012
\015\012If that does not solve the problem then just comment back here to this page with the answers to the above questions and I will go into much greater detail about the various troubleshooting procedures you can employ to diagnose the problem with your tv.
\015\012
\015\012Thank you very much and good luck.

I have a Gateway p46m103 flat screen television that will only turn on after plugging and unplugging the power cord many times. It would eventually turn on each time I tried this. Now, however, the green power light comes on, and I can hear it is on, but the screen is all black. I even tried pressing the Input button on the front of the television, to see if I had accidentally changed it, and even the icon on the screen will not show, to see if I am seeing the cable box, or the dvd player, etc.

I plugged this TV into a new cable box (digital signal, not HD), and the picture now does not fill the screen. Previously, I had another TV (different brand, same tyoe and age) plugged into the same cable box, and never had a problem. Is there a way a) to adjust the picture to fill the screen without using the zoom feature, or b) if not, is there a way to make the zoom feature permanent so I don't have to activate it every time I turn on the TV?
