Question about ViewSonic N2750w 27 in. HD-Ready LCD Television

Blank screen except for a vertical grey line through the middle

I have a lighty used (2 years old, 50 hours of use max)N2750. When I power it on, the screen is completely blank except for a vertical grey line in the middle. It is completely responseless. I can't toggle between inputs, the remote control does nothing, non of the buttons on the monitor do anything. No PC, no TV, no sound. Just a vertical grey line in the middle. Any suggestions out there? Thanks in advance. Jim

    Thanks for the advise. I guess I'll be performing some minor surgery here shortly. I'll post back if I find something. Thanks again.

    It is a LCD TV. Just like my original post states, there is no picture or sound, just a vertical line, I just closely inspected the vertical line andI found that it is actually made up of 3 lines (red, blue, green) but it still looks like a vertical line going across my monitor from the bottom to the top.

    Same thing, this is a pretty new tv, and all the sudden yesterday, it blacked out to a small line going through the center...you can tell normal cable is running...you can see a fraction on the channel...what could this be?

    same problem. 2yr old sharp TV that all of a sudden, 2 days ago, when i turned it on it had a vertical line in the middle of a blank screen. Still doesnt go away. was the only solution to change that vertical thing? would it cost more to do that, through a repairman then it would be to just get another tv. it is a 37 inch.thanks.

Your tv vertical circuit is faulty there are some caps in the vertical section change them, also you should be getting about 30volts on the vertical ic leg 1 out put if that is absent change it also check the vertical yoke winding it could be open.there is also a diode that feeds the voltage from the base of the hot to the primary winding of the flyback check and see if it is open.good luck

The horizontal sweep signal to the yoke is bad. Since other problems exist, the problem may be in the IHVT HI voltage transformer area. Check for bad solder around the IHVT pins and yoke plug. I hope this helps. Lee http://www.CrazyComputers.com

Screen is black except for thin line in middle of screen

The problem is in the vertical section of the main board. Bad capacitors and maybe the vertical IC. If you are not inclined to be a tech you will have to take it to a shop.. I don't know what they may charge but I normally get $69- $89
