The popping sound was a capacitor that failed the big way. Since the sound works just fine and the image faded (it didn't just dissapeared instantly) then the problem is in the backlighting - either the inverter or the output line that is powering it has failed.
This will be relatively easy to fix and not very expensive but must be done by a pro - he will replace most of the capacitors in your tv (the one that failed and all the other because they are also nearing their end).

My maxent tv has splotches on the screen


That sounds very much like the screen has been damaged, perhaps by a knock or a bang?

Do the black marks look something similar to this picture:

Check your remote of a button labeled (Format, Aspect Ratio, Screen size etc, you may have the tv in 4:3 viewing mode. If you are on a cable box and using its remote check for same named buttons.

Himaxent P420142x3. Screen picture has gone. Cannot see menu options so screen has gone and it made the click sound when it went off. Sound is ok. Recommendations?


When this happens you hope that the only thing wrong is that the inverter(s) are loose, and this is usually the case. If the inverter cable(s) are checked and that is not the problem, the next thing to check would be the inverter board, which would have to be replaced in its entirety. For non technical troubleshooting you can try leaving the television unplugged for as long as a day or so or keep turning it on and off to try and get the picture back until repairs can be completed on it.

Need a way to remove bottom base stand on am Maxent Model # P420142X3. Mounting on a wall becomes a problem with the base stand attached. Have tried removing screws with no success.


I don't know why it won't come off, only 4 screws hold it on. It should just lift off of the stand.

Once you do get it off - I'd be interested in the measurements, if it's the right size, I'll buy it off of you. Email me at John_Schaffer@comcast.net if you're interested. Thanks!

My maxent p420142x3 has sound but no picture?


ha ha ha this problem is caused by the Y-SUS or Y sustain board (any name is used for it) if you open your tv you coud see around 4 big boards, the left is the Y-sus, if you test its two fuses you can see one of them are blown that means that your YSUS is blow it, the part is 6871QYH953A. and the price is from 35 (the fix kit) to 280. I'm sorry for my laugh but I had the same problem and found it that this model of board is LG and around 18 brands and diverse model of TVs have inside this piece of **** and all of them have the same problem sound and no image.

Red spots


what you can do is take off the back pannel and there is a cord on the top of the board that looks like a computer board, there are many boards in the TV but the one I am talking about is twords the bottom where the video jacks plug in to the TV. Ok once you have located the pannel there is a cord on the top kinda tword the right side, it is many wires inside a black covering. What you need to do is just simply unplug it and plug it back in, do this as many times to try to get it to work. If that doesn;t work you can replace the cord and if that doesn't work then the screen is out and would cost WAY too much to fix, you could buy you a new name brand TV.
