You either have a hardware problem with your video card. ( may have pop out of socket when you plug in the monitor) or the cable is not allow communication to the monitor. As long as the amber light comes on you know you have power so focud on data cables and hardware.

Dell Inspiron 2350 All-in-One Desktop PC Fault Flickering Touch Screen


It could be 1 of 2 things, either your monitor is going out on you, or your graphics adapter is going bad. Depending on how long ago you purchased it, and from whom, I would contact Dell service to find out if they can return it, or give you any suggestion.

Horizontal line appearing on desktop


The fault looks like white lines horizontally along the screen. These are the retrace lines that become visible due to absence of proper screen/grid voltage. You will need to open the monitor only if you are familiar with power electronics, a bit of experince is important as the stages are delicate and contains high voltage. If not take help, check for faulty capacitor or low value of resistors in the screen/grid sections of the crt. Couple across parallel to the suspected capacitor to confirm and change. Use a meter to see the voltage across faulty resistors. In some cases reducing the screen potentiometer ( onthe Line output transformer)can solve the faulty. Hope you try. Good day

2 problems, monitor color and update possible?


well it sounds like the color scanning chips in the monitor are going<have gone> bad. If you have access to another monitor I would hook it to your system and see. XP may run, depends on your processor speed and RAM amount, also graphics can be an issue in XP

No image but only two bright white horizontal lines in the middle


Try checking the monitor and monitor cord to make sure they are working properly. Try it on another computer and see if the lines are still there. If they are, then you will need a new monitor and if they are not, then you may need a new monitor port for your computer. You will need that checked by a professional to be sure. If you can, open the computer and check the connections from the monitor port to the motherboard and make sure they are ok.


To contact me, just re-post and I will try to answer any questions or comments immediatley.

Westinghouse monitor model lcm 19w4. Screen keeps going black and you have to turn it off then back on to get screen back. Sometimes screen will work properly for hours, but sometimes keeps happening...


This looks like a power supply problem, due to internal
over heating. When it cools down, the power supply turns
back on, or an "over current/ thermal" protection circuit
trips. Shutting of the monitor off resets it, and then it trips
again.

I had an old Samsung 19" with an identical problem.
(see my other post)

Mine was caused by a leaky capacitor, but every
monitor is different. (I have considerable knowledge of
electronics, as well as a degree in engineering, so
I was able to fix it, but I would not recommend this to
a non-tech person.)

The 19w4 seems to be a fairly new wide format monitor,
probably still under warranty. I would take it back to the
store on a busy Saturday afternoon and scream blue
murder.

There is absolutely nothing you could have done to cause
this problem, nor is it normal wear and tare.

It is the result of sub-standard manufacture, and you have
every reason to take it back. Your case is stronger if
you don't try to open it.

Good luck, Martin.

My Westinghouse LCM-19w4 Monitor will not turn on,..it just blinks and nothing


I just repaired my LCM 19W4. My symptoms were a little different; the light was not on or blinking like yours. I replaced two bad capacitors today (220 uF 25V High Temp) So far so good. Bad caps can be easy to identify; they are slightly bulging at the top. Soldering can be very tricky though. But just like plodder said, make sure it's the monitor that's bad and not something else by hooking up a known working monitor first.
