Screen stays blue and wont show the picture


TV may be on the wrong input and that will give you a blue screen. When you turn the TV on and the screen starts lighting up it should show on the screen what input the tv is on. If it is not on correct input change input with the TV remote or buttons on the tv. If it is on the correct input try a power cycle on the cable box, just unplug the cable box power cord for a few seconds and then plug it back in. If neither of these solve the problem describe how the cable box is connected to the tv.

Sounds like the problem could be in the power supply of the TV. Have a technican check for defective capacitors if you're not equipped to do the job yourself.

Do you have the input turned on that you use the xbox for? Try different inputs as well. If you are getting the menu to come up, the blue screen is telling you that you don't have a signal being run through that particular input.

I only get a blue screen with "No signal" on it. it doesn't stay on it shuts off automatically.


Power on your TV and press the INPUT button on the side of the TV repeatedly and rapidly until you can change it to a different input, such as AV.

If this does not work. Try this: With the TV off, press and hold the input button on the side of the TV for about 5 seconds. The TV should power on and the input list will appear. Let me know if either of these work.

Red colour does not appear on screen.


It sounds like you have a bad VGA cable. Check for a bent or broken pin in the cable. These often show up as a loss of one particular color: red, green, or blue.

Hdmi inputs stopped working


It sound like the cable box or the Blue ray player is set to high - such as 1080P when the set is only rated at 720 - try scaling the output down and see if that helps

Another question about maxent plasma monitor


Yes problem is repairable sounds like the mainboard (video) needs replacement because the rgb is part of this board along with the rest of your inputs this should fix your problem. There are some models where rgb is seperate but not many I will need the model number of your Maxent to be of further help.
