I have unpluged and pluged the power cord and the LED is orange for a few seconds and then turns green, when I push the buttons in the fron panel the TV does not repond, I can't turn it off or change channels, and have the same problem with the remot. The screen is black but I can hear a sound

Sounds like power supply switch needs to be changed to normal setting. If you are comfortable with electronics i will talk you through it if not you will need a tech or back to cosco it goes if you have a warranty.

Hi Bruno,

First of all thank you for posting your question here at Fixya.

I'm assuming here that your TV's model number at the rear panel is MX-50HPT51.

My first advice is to unplug the unit from the outlet (AC source) for at least 1 hour to drain any voltages from the boards and to reset itself and then plug it back in and check if the symptoms still persist.

If the symptoms remain the same, this is an indication that the logic control board of your unit gone to malfunction. It is located at the center inside the set. See sample picture of logic board used for Maxent plasma TV at the end of this solution.

Please note that this is not your actual logic control board, it is used for another model no. I've attached it to give you an idea what it's gonna looks like. I've checked my link online for your logic control board but they are currently out-of-stock. I would advice you to contact your local Maxent sevice center to obtain the board.

Also, don't forget to check if your unit is under warranty/extended warranty period, avail it because the manufacturer will fix it for free. Opening the rear panel will void the warranty.

Please let me know if you need further assistance.

Hope I helped you.

Rating and feedback are highly appreciated.

Good luck and take care!

Kind Regards,

Jazz Electronics

I have a Maxent 50" plasma TV model # P5000550H9

Here is a link to the RETREVO site which has a PDF copy of the complete User's Manual for the Maxent 50" Plasma TV:

Just use your mouse to click on the link, which is the underlined and highlighted text just above.
This will open a new web browser page automatically for you and allow you to view the information at the website indicated.

When you get to the RETREVO page, click on the blue DOWNLOAD THE DOCUMENT (2.64MB) button on the left hand side of the page under USER MANUAL FOR MAXENT MX-50X1.

Once you click on that and get to the next page, don't bother typing your email address in the empty box, it's not necessary.
Just TYPE THE NUMBERS SHOWN BELOW into the second empty text box.

Then click the red DOWNLOAD NOW button.

When the computer asks if you want to open or save the file, CHOOSE OPEN.

If it does not open, then you may need ADOBE READER installed on your computer to read the PDF document.
You can download this free at WWW.ADOBE.COM if necessary.
Click on the DOWNLOAD ADOBE READER button on right side of the ADOBE home page when you get there, then follow the onscreen instructions to install the software on your computer.

Please comment back here to this page if you have any details to add, have any questions, have difficulty accessing the links, or just require further general assistance and I will respond as soon as I see it.

I hope that was helpful to you, good luck and take care.
