Having problems with your ViewSonic Optiquest Q19wb LCD Monitor ?

My Viewsonic Optiquest Q19 monitor blanks out although the light stays green. If I turn it off and on again, I can see for a few seconds (sometimes for longer) but then it blanks again

Answers :

Sorry about your problems with the View Sonic 19” Monitor.
\015\0121st. thing you have to decide is weather the unit is worth repair and if you have the technical background to complete the repair.!!
\015\012If the power Led stay’s on and the video blanks out, it is most likely the backlight tube.
\015\0122nd. You can tell for sure, if you use a strong flashlight and see data on the screen.
\015\012 If you can see data or images, it is the backlight. If the inverter board was bad, it would shut the power circuit down and you would not have continues power from the supply.
\015\0123rd. The backlight is not an easy job to undertake. Again, if you have little or NO technical background, you may want to pass on this project.
\015\0124th. If you decide to take on this project, you will need to order the backlight and if you are replacing that, you might as well check the Caps. And other components in the power supply and inverter board.
\015\0125ft. The backlight tube is cheep and can be purchased locally for under $10.00 USD
\015\012I needed to order a 15.1/4” tube for a laptop and decided saving 2 or 3 bucks was worth the investment. However, I ordered from China and had my tubes held up for over 5 working days and could have walked to the manf. And back by the time I had recvd. them.
\015\012Decide weather you want to repair it yourself, or have it serviced. A 19” View Sonic can be purchased for under $100.00 New with High Def.
\015\012The in shop repair with have to be more than the unit is worth.
\015\012Hope this information has been of some help.
\015\012If you decide to take on the job, drop me an email and I will go into better detail on what and how to do.

\015\012Enjoy, and be safe.!.
\015\012Try it, it just may work…!!
\015\012You have a monitor with a common problem. After a few years some LCD monitors\015\012will blow a power supply. The problem is caused by parts called\015\012capacitors overheating in the confined space of he monitor. If you are\015\012good at electronics repair/soldering you can usually fix he problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm\015\012You can take the back cover off your monitor and look for the bad parts,\015\012replace any that look like the pictues and your monitor should work\015\012fine. The capacitors do need to be installed with the correct + and -\015\012connections, note the stripe on the old one and insert the new one the\015\012same way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping. I hope this helps, if so please rate my solution.
