Question about Maxent MX-42VM 42 in. Plasma HDTV

Maxent MX-42vm10 42" Plasma

A freind of mine thought she'd be helpful and hook up my plasma to my new stereo receiver, and plugged the cables from the amp to the external speaker jacks on the side of the TV. I was out of the room, but she said it just turned off when she turned up the volume. (I still wince when i write this). The tv powers up, but won't come out of standby (amber light on front), even after being unplugged for over two weeks. Is this TV shot? I can't afford to ship it to the manufacturer, or to replace too many boards. I've looked for fuses, but the ceramic ones I see look fine. I can plug in boards and check fuses, I'm not familiar with anything beyond that. I got this tv for a steal of a price, so I'm not that upset, but I do like it, and can't afford to replace it right now - I would be very grateful for any advice!

    As a followup, I removed the back of the unit, traced the speaker terminals to a small board inside, unplugged the board from the main board (being VERY careful of those big nasty capacitors in there), and crossed my fingers...and it's working! None of the ceramic fuses were blown elsewhere, and all the inputs work.

    No sound, obviously, but besides that, the tv is working perfectly, as before. Since I had planned to use a receiver with it anyway, this is a fine fix. If I ever sell or give the tv away, I'll replace the board.

    Thanks for your input, anyway - I think I lucked out on this one! PHEW - very relieved, and happy my tv is back.

On the back left side of the tv is a power button, it might be turned off. Also the square box attachedment that I have on mine never stays completly connected which turns the tv pink then green. I sometimes unscrew the six screws from the back that holds that box out and then put it back on. When that don't work I smack that box that always work ! good luck1

Generally, if a Plasma Tv is not coming out of standby, it means either the main board is faulty (most likely case) or Power Supply Board is not giving enough power to Main board to switch on the TV. In your case, I think it's the main board (aka Motherboard). Sometimes it's hard to tell to whether ceremic fuses are blown off by looking at them, so it's best to check with a multimeter. Check the fuses in the PSU and also whether it's outputing correct voltages. Also, can you hear a clicking noise right after you've switched on the TV or pressed the power button in the remote to make the Tv go from standby to ON. A clicking noise means one of the boards is shorting out. In your case, I don't think you'd hear a shorting out clicking noise, and I think replacing the Main board will get you out of standby.

Your Maxent MX-42EPM20 is not a TV (Television) it is a Plasma panel. The difference being your Panel does not a TV Tuner (no Coax jack or electronics relating to a tuner) Below is the spec sheet that shows this;subnav

You can use a cable box or a cheap Digital TV receiver. You can buy them at walmart, You need one with A/V out puts such as Component. Here is a link to one. This will give you a tuner.

Most likely your YSUS board. I replaced the module on mine and got it working. Unfortunately after 2.5 months it is out again. Awaiting ideas to persue as to why and how it can be resolved. The module is available on eBay but keep in mind the module is a real bear to get off the board without doing any damage. Hope you have better luck than I am having with mine!!

Maxent plasma tv is showing only vertical lines.

Common problem on these sets are many many bad caps on the digital board. Repair kits are available for these containing the necessary parts if you're savvy with a soldering iron. Otherwise, replacement of the digital board is necessary and you'll have to contact either Maxent or a local repair shop. Tracking down which caps are bad can be difficult even with the right equipment as some tend to check good while in circuit when they are actually bad.
