How do I tilt my Samsung 190s monitor?


If you mean tilt back/forward, grab the screen with your hands from both sides and tilt the top towards you are away from you.

If you mean rotate to get vertical instead of horizontal orientation, you should look at the back of your monitor to see if it even allows that movement.

Try downloading the User Manual if you don't have one:

Screen is black with power light on. When I turn the power off and then on the screen comes up for a split second then goes black again.

My hp w1907 19' monitor goes black light stays green


There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

Monitor flicks on but does not stay on


Hello,

You have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of he monitor. If you are good 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 You can take the back cover off your monitor and look for the bad parts, replace any that look like the pictues and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the stripe on the old one and insert the new one the same 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.

Hi dgp1952, Check with www.lcdrepair.net if you want a repair. Something is wrong with your backlight or the circuit supplying power to it. If your technically endowed, you may want to open the monitor case and clean the dust and lint from around the circuits using a Small paint brush to sweep away any built up dust. Dust can cause the circuitry to heat up faster and put the power supply into Clamp mode. Clamp mode will turn the supply off to certain circuits which may be the reason your display is going black after 5 minutes.
