    1. Andersson Tv A3222d Manual

    The backlight with this model is built into the LCD display assembly and draws power, through a separate backlight cable, directly from the device's power supply and depends on the logic board to provide backlight information.Diagnosing the failure in this would require you to use a digital multimeter, set to DC, to check for 23.3-25.7 V between the chassis ground and the 24 V test point on the logic board. If no voltage is present then the power supply is likely bad.

    If proper voltage is present then you should inspect the LED backlight sync cable, which is attached to the back of the LCD panel, for damage and then reseat it. If the issue persists then the next step would be to replace the LCD panel or logic board, in either order since they are both costly components.Hopefully that gives you something to go on.Here is a, the backlight portions of the internals are very similar to your model. Hello All,I did as 'LikeARabbit ' suggested above, and it worked for me.I was having an issue of a very dim to complete shutdown of my Apple LED Cinema Display 27'.I opened the cinema display as per the instruction from the.The inside are almost the same as I have both and can attest to this.I tested the power on the logic board that 'LikeARabbit' suggested and mine was running a consistent 24.3 V on my digital multimeter. As to where to test this, please see attached photos.

    Sorry for the bad quality photos, but I had very little time.Since my power was within in range I made sure all the cable were seated properly by unplugging and replugging them one at a time. Do this with the power cord unplugged so you do not fry the boards, LCD, or yourself.One plug I noticed right away was the 'Function' plug which was very loose. I believe this is the LCD background lighting system as it istantly increased my brightness after reseating this cable.After powering the LCD up, I moved this one cable around a bit, and sure enough, it was the one causing my issues.

    It is now properly seated and I have not had any problems as before. The LCD is working as it did when new.I did create new monitor profile after this as I noticed the colors were off at this point. I am a photographer and need these LCD to match. With my iMac 27.Below are the photos of the cable that was loose inside my Apple LED Cinema Display 27 and the two connections where I tested my power to the LCD backlight system.I hope this helps.Kind regards,Johnny. I had the same problems. Backlight was gone or very low.

    The short story: I found out that the micro controller does not send the PWM signal to the LED driver. Very mysterious! I checked the LED driver components (Mosfett, diode), I read the data sheet to understand the function of the HV9982 (LED driver). In the end there was no hardware problem there.

    If I connected the computer the micro controller enabled the LED driver but 'forget' so send the PWM signal, so the LEDs stayed off. Mmmm.maybe this is a software error or Apple wants to tell me to buy a new one? So I bridged the PWM input pins with a little wire connected to a 3.3 V pad (which I found about 1 cm around). Nice that die PWM output pins of the micro controller were bridged by 0 ohm resistors, so I could remove same and cut the connection from the micro controller. And then I got full backlight again. Of course I am not able to dim the backlight anymore.

    Cover the end of the TiVo remote control with your hand.2. Hold down the TiVo and TV Power buttons simultaneously until the red (or amber) light on the remote control remains on.3. Remove your hand from the end of the TiVo remote control.4. Enter code 0999.5. After you enter the code, the red (or amber) light will flash three times and then remain on.6. Press Channel Up once every two seconds. This will test hundreds of codes, one by one.

    Do not go any faster than this or you may skip over a code that works.Reminders:. If you press Channel Up and your TV turns off, press Enter to select the code. Press the TV Power button to test the code. If your TV turns on, you have successfully programmed the remote. If you cycle through all the codes, the red LED will go off, indicating that you have tried all the codes.

    If this happens, or if you selected a code but the TV does not respond to the test, try again to make sure you did not skip over your code by going too fast. If you can't find a code that works, your current remote may not be pre-programmed with the code for your TV.
