    I guess it is time to get a new monitor.
    Thank you for your comment. No point to invest in reparing it. New monitors are not that expensive and with many more features

    Thanks for your support

Have you tried it on another computer? if not do it so. It would be important for me if you can let me know how this was happened. Did you make any changes or was there power failure? Please let me know so that I can help you the source and the solution for your problem.

    I have this comp. at home. Normally I log off and then when I have to work was ok. About two days ago, I noticed that the screen remain black . Normally there is an small screen saying "no signal available or something like than, but within the last two days the screen was completely black. I turned the comp. on and off several times and did not have a video signal. I brought the monitor at work and I plugged to my computer and the screen continued to be black. I went to another computer and did the same and the monitor continue black and there is nothing saying no signal available.

    Do you think is toasted?

    Well, since you haven't answered my first question, I would assume, you've tested/tried it on another system without success. If there's power failure and thunderstorm, the most likeliest damaged part inside the monitor it it's inverter. It a kind of chip (most new lcd monitors have smaller board inside the monitor which is called the lcd inverter), if this fails, monitor will not display anything on the screen. Since it can be turned on, i would not suspect the power supply unit. This chip "lcd inverter" is available in the market, but if are not ready to able to open it apart, I would suggest you to call a local tech or take it to a repairing/serving shop. It's definitely reparable.

    You can also check the monitor whether you can see dark display or not. If you can see something, when you light a flashlight on the monitor, (you'll be able to see very dim-negative like images on the screen, not the shadow, but the display of your desktop), then it's with the back-light lamp. Please do check it before you go ahead so that you can find out the exact problem.

    If unfortunately theres problem with the board, you'll need to spend some more, and it'll be better for your to get another new monitor.

    I wish you good luck.

    Thanks for using FixYa.

Nothing shows up on the screen when I push any buttons. It will turn on, but after that nothing I push shows up on the screen. I have taken the batteries and the back up battery out.

Does the cursor show up at all? TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.
