As well as connect the cable with your panel which you want to read the data. Make sure to check the power source side before connecting the cable. Third Step: And now open your program operating the application on your computer system. Fourth Step: Now click on the serial print, panel data will appear on the screen.
In the data sheet below ( Figure 6) the LED backlight voltage (V) and current (I) is in DC. The EL backlight power is 110V ACand it shows the frequency to be 400Hz. That means that the voltage on this EL backlight switches between positive and negative 400 times a second.
When I checked the voltage that goes to LED backlight, it was zero. I suspected that the LED light might have got shorted inside. So, used an LED driver tester and found that the LED was getting on with a reading of around 69.4V. The suspicion was on the driver circuit. I got the pin details of this LED Driver IC SN51DP from my techie friends.

Photo: Prove to yourself that an LCD display uses polarized light. Simply put on a pair of polarizing sunglasses and rotate your head (or the display). You'll see the display at its brightest at one angle and at its darkest at exactly 90 degrees to that angle. An LCD TV screen uses the sunglasses trick to switch its colored pixels on or off.
After that you have to check all the panel voltage which is necessary for drive a TV panel. 4. Check CLK signal. Some times we get this No Display sound ok problem because of CLK signal missing on the panel. So check this problem also. 5. Check CKV signal. Many time we get this problem for CKV signal.
