Turn off the closed captioning. You have it in text mode probably.

Mine did this for a while.  I recently moved and the problem has miraculously disappeared.

Viewsonic N3250w. Power supply went out and I replaced the bad capacitors. TV worked for a week then now when I turn it on, the screen just turns on and off


Check to see if the 24vdc disappear when the screen black out, it is always there then you have problem in the backlight inverter board. Did you replace the caps in the 24vdc supply also? I replace the whole set.

My ViewSonic N3252 display is just a black screen in all inputs. Sound works fine but no picture.


As with most LCD screens the two most problems that cause black screen are bad a solderjoint on the inverter board or bulging capcitors, the next problem would be most likely the power mosfets witch break down after time.

Black square on one channel


that's a picture inside a picture option, and it sounds like the inside picture is set for a blank channel...just go to the menu, and shut off the picture in a picture option..should do the trick..

ViewSonic N3250w has black line


Unfortunately, my experience with LCDs says that when you see something like this, it usually indicates that the LCD screen is cracked. If you press gently in the area of deformity and it goes clear then returns to black when you remove pressure, it's a tell-tale sign of a cracked screen. Go to e-bay and see if you can get a replacement screen if you're mechanically up to changing it yourself, else an electronics repair shop might be your only hope.
