Re: viewsonic VG919S 19" LCD


You must focus to mainboard of LCD monitor find the voltage regulator IC. Voltage test the regulator IC use digital or analog multimeter range 10v dc connect the negative to cold ground, these regulator providing a constant supply of 2.5 - 5v to all IC in the mainboard. check the scalar IC. Because scalar IC will convert analog input signal of Red, Green & Blue. Lastly check the controller board, check the ribbon cable connector from mainboard to
controller board for lose, check the fuse inside controller. I think the exact problem of your monitor could be either the (mainboard) or (LCD panel where the controller board is located).

Please check the VGA cable at both ends to make sure there are no bent pins and fit into the socket properly at both ends. Also try this monitor with other PC also since it can be in the video card.

Check the information at Viewsonic's website regarding their warranty:

If you have your proof-of-purchase and it shows the monitor is less than a year old, it would be covered. You would need to follow the procedure on their website to have the unit repaired or replaced, but it would not be your job to try to fix it.
