No thanks, I will use my own endeavours rather than having to pay as this issue is not so much a need of advice as just finding a part. Thanks anyway, I shall keep your address for future use when required.
Thanks

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

Hi

This will be your screen controller board that has failed also known as the ldv's board, With the back removed from your TV it will sit below your power supply and be connected via a ribbon cable to your Y Sustain board on the left.
Remove it and take the part number of the board then Google or Ebay for a replacement.

Take a look at the below link so you know what you are looking for.
Hope this helps

No video but audio is fine on Sanyo 42" DP42746 TV


If you unplugged the Ysus board, then you need to replace the Ysus board, or both sustain boards. This is the part: The part is often available on Ebay, or from manufacturer. Look also at Vance baldwin or Partstore. To do a good job the Sustain boards should be tested by a tech , following service manual. It is almost for sure sustain board by the way.

Cracked plasma screen


A plasma display is a very expensive part to replace. When the plasma display is broken, the tv is usually not worth repair.

Call Nec at the number listed on the owner manual, and ask a quote on part or repair.

Power supply issues


hi there, i recommend replacing the entire board. once you have a short like this, the micro board itself will become useless. the thin micro circuitry has become separated within the layers, preventing a closed current transfer. its best to order a new canvas so to speak.
