Question about ViewSonic N2750w 27 in. HD-Ready LCD Television
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
This is a lcd. there is no yoke. it's a bad panel.

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
