Question about Maxent MX-42XM11 Television

1 Answer

Maxent 42" Plasma TV takes 3 - 5 minutes to sync after turning on

This began about 8 months ago, when I turn on the TV for the first 3-5 minutes I can only hear the audio and the screen is dark gray or black. After about 3-5 minutes, the picture begins to flash on and off until picture finally syncs up and we can then begin to watch TV normally. If I turn off the TV and then turn it back on a few seconds later it works as expected. However, if I let it set for any length of time and the unit cools, it will go through the warm up and flashing process until synced.

    Same problem here, though it seems to be getting worse...

    It seems that as time goes, it takes longer and longer to load up, and even when it's good, it will flicker an inch or two of a bar across the bottom when the picture has a lot of white in it... then after a few hours of being on it seems to work great...

    With what little info I have on electronics (building HAM radios, etc)... It seems to me that a capacitor is blown, and takes a while for it to get up to charge to keep the power clean... Most TVs have a safety for this (as it can damage the internals) but it seems that this one doesn't. If you or anyone else has found a solution (or know if a repair shop can fix) please post here. I don't want to pay a table fee for something that can't be fixed.

I had the same issue....thankfully, I had purchased an extended warranty from Best Buy...I had been in a panic, because I NEVER thought I would pay a grand for a tv, but I LOVE it...anyway.....I had the "Geek Squad" come to look at the tv....the tech took 30 secs....there is a problem with your Y-SUS (Y-sustain board)...it will need to be replaced...and...the tech called another tech, and he advised that the Z-SUS be replaced as well (apparently he had to go back to the same home after a Y-SUS replacement to change out a failed Z-SuS).....retail on Y-SUS is about $300...ebay has them for less than half that, if you think you can do it yourself...keep in mind that "Maxent" is a Zenith/LG product, so finding parts might be a challenge if you base it upon Maxent....hope this helps!!

Are you sure that its the main A/Vboard coz it sounds like the main power supply issue to me. Anyways the mainboard is the large board usually located at the center of the tv. If you can remove the back cover of the tv and get me a high res picture of the tv I can mark the board for you.

Vertical black lines appear intermitently


Does the line appear on just one input(cable,hdmi,video1,video2,ect) or on all of them? The reason why I ask is it may be just an issue with one input setting on the television and you may be able to use a different input for a temporary fix of the problem. Plasma telivisions run very hot and it may be overheating. Try using a small mountable fan above the TV pointed into the back heat vents and see if keeping it cooler keeps the issue from happening. These TVs are repairable but usually cost more to repair than what it is worth due to plasma TVs are very in-expensive now.

Maxent 50" plasma problem


We seem to have had the same problem. Green light keeps blinking but will not turn set on or off. I unplugged the set for a few minutes, plugged back in and works fine but will happen from time to time for no reason.
