Maxent MX50X3 HDMI input

I have two problems with my Maxent MX 50X3. One is when my Comcast HD Cable box is plugged up using the Component video cables i get, what my cable tech calls, hum bars. I don't know what to do to get rid of this problem. The only thing that worked, for some reason, is using the HDMI input. When using the HDMI the picture was excellent. This brings up problem two. I came home one day and the HDMI input doesn't work at all. I just get a blue screen. I tried plugging my Samsung DVD player up, thinking it may be the cable, but the problem remains. Now I'm stuck using the component video with the hum bar problem. Also my 360 uses component video and has no hum bar problems. Can someone help me please?Same problem I am facing with HDMI.Does anyone know how to fix it?

Hello,
I have a Comcast HD Box hooked up to my HD TV and I had the same problem with the component cables and the HDMI cable as well. I called up Comcast and they had a Tech come out the next day and check the wiring, they tried a new box then a new component cables and they also tried the old HDMI cable on the new box and it turned out to be the component cables and the HDMI cord. To play it safe he brought up some YPBPR cords and that fixed it. This was about a half of a year ago and it is still working great and it seems better than the HDMI cords. The YPBPR cord you can buy it yourself or you can call Comcast Customer Service or go to your local branch for the free one.

Thank you for using Fix Ya!

I recommend making sure that all the equipment you are connecting together is plugged into a common plug strip or are fed from a common plug. This assures that all the power inputs are at the same voltage level and should eliminate the voltage differnces between units that can occur when plugged into different sockets. Sometimes one socket will have a different ground connection or a bad/missing ground and this is the cause of the hum bars.

Thanks for using Fixya

Hi!

The Component cables aren't working due to bad filter in the power supply or due to loose connection inside the cable box.

Try using co-axial cable and check for the picture.

Also, check for HDMI cable. is it faulty? is it working with other unit?

If it is faulty then replace it.

Please ask for any further clarifications

Thanks
Rylee

Change all the connecting cables initially and then check if the problem goes away.

This unit doesn't have a tuner, This is what I found when researching this question for you.Maybe you can hookup DVD player or VCR player with audio and video cables, I know some VCR's have HDMI on them too that can be hooked on that TV. Good Luck

I have a 42 inch maxent but i dont know where to plug my cable cord because i have a comcast box and theres no where in the t.v to plug my cable cord


If your comcast box has video (yellow), audio R (Red), audio L (White) out, just connect RC cables to the input of the TV at video, audio-in RC Jacks. If your comcast box has only RF out, buy one RF to audio-video converter and then connect these to the TV.

I am having problems programing my Maxent MX50X3 TV to our Direct TV system.


Hi, Your Direct TV system runs on channel 3 or 4 on the Maxent HDTV and the decoder box(PVR) works all the channels. So you might not be able to program your HDTV. Good luck.

How do I hook up my maxent tv to cable


use 1 of these 4 options
On the back of the cable box there should be outputs
Coaxial ( regular cable wire that screws on)
RCA plugs (yellow red & white )
Component plugs ( green, red, blue for video) (red, white for audio)
HDMI ( on HD cable box only)

After connecting make sure your tv is on the input you connected on the back of the TV

My antenna has a coax-my 50 in Maxent mx50X3 has no coax hook up. How do I connect these two?


That unit does not have a tuner so it does not have an antenna input. You need to connect a cable box, satellite box, VCR with a digital tuner (or an additional DTV box for converted input), or DVR to one of the HDMI, S-Video, or Component inputs to view TV.

Maxent MX50X3 HDMI input


I had the same problem and found that the ground wire outside where the cable companys box is was not even hooked up. It was just hanging there, once I hooked it up it went away. The cable company gave me the run around telling me it wasn't their fault. I now have Direct Tv.
