in power outlet, RC Jack, cable and connectors, the TV might need service.

Lower right corner of screen has developed a large black square.


Hello kailuajacqui:
It sounds like someone has turned on the picture in picture option on your Television. The reason it is a black screen is because it is not setup on a station or other input in order for you to see anything.
Check your manual for how to turn off your PIP (Picture in Picture) option. Or just hit the PIP button on your remote control.

If this helped just click the thumbs up.

Element electronics LCD, was on for several hours picture went blank, sound is still perfect. 12 hours later still no picture when turned on, great sound though.


Typically this failure is due to the backlight inverter going out. On this model of tv there were two runs with different parts. Open the back of the tv and open the control box. If you see a large black circuit board on the top, replace that one. If its tan then you need to take out the control box and remove the black plastic backing. If you're looking at the back of the tv the inverter will be on the left side of the control box. Its a long skinny board that has 8 black metal squares on it. Good luck and be careful.

Loud pop no picture


The common cause of this is some of the large power supply capacitors become faulty.
Check the power supply printed circuit board for any capacitors, the look like cylinders, that have raised or popped tops as well as any sort of black or gluey sticky substance around them, which can become conductive and cause problems.
If you find any that fit the description of faulty, replace them and any neighbouring caps around them, also check for any other burnt out spots on the pinted circuit board as this normally indicates another faulty component or one that will fault soon. Good Luck.

I have a black square in the top left corner of my Prima TV when watching a TV show, but when I press the guide on our satellite receiver it goes away, but returns when I return to normal viewing.


Look on your remote for a function called POP or PIP, if you do then that must be turned off. It sounds like you do have it. If you don't see it then go into your menu under features or under that order, and look for the Picture in Picture feature. each manufacturer calls it something different.

Black squares or rectangles over picture


It's the closed captioning. The reason it doesn't go away when you press the "caption" button is because there are four option for closed captioning: Text 1, Text 2, Text 3, and Text 4. The fifth option, which has no designation, is the "off" option. Using the remote, just click on the "caption button until the option has no designation.

Mine was a large black rectangle in the middle of the picture. It's not like Nina3's problem.
