SAMSUNG SYNCMASTER 191T PLUS

hi the cause is screen back light not working properly. you need to remove the back cover of the monitor to access the internal part of the monitor. then look for the connector of the cold cathode fluorescent tube back light going to the power inverter board of the back light you will noticed a dry joints which cause a loose connection that is why you hear a sound that cause of spark. you need to re soldered the connector or replaced if totally burned.

I have a strong suspicion that you have burned a capacitor or two on the monitor. You will need to bring this in to have it serviced as it will require the monitor to be opened up and new capacitors replaced/resoldered.

Your monitor has a bad INVERTER, look on eBay.

If it worked on a computer at the IT person, it is most likely a faulty graphics card in your computer. You may want to get that checked out.

i think it can be the capacitor problem, open monitor an look for swollen capacitors. if you will find them swollen or mso 9]> Normal 0 false false false MicrosoftInternetExplorer4 mso 9]> mso-pagination:widow-orphan; font-size:12.0pt; font-family:"Times New Roman"; mso-fareast-font-family:"Times New Roman"; mso-ansi-language:IT;} @page Section1 {size:8.5in 11.0in; margin:56.7pt 42.5pt 56.7pt 85.05pt; mso-header-margin:.5in; mso-footer-margin:.5in; mso-paper-source:0;} div.Section1 {page:Section1;} --> mso 10]> /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} loosing the electrolyte, signs of burn, change them

This is a problem with the capacitors in many different monitors. I have 5 IBM ThinkVision monitors sitting on my desk at work with the same problem.
If you know what you are doing, pop the monitor open and have a look at the powerboard inside it. There are four main capacitors, and its likely one or 2 will be popped. Get some replacements, solder them in and you're set.
Again, only if you know what you are doing. $3 of capacitors is cheaper than $50 repair.

You will need a new monitor screen. I have had two screens go on me recently and what you describes normally happens

Your first step in troubleshooting this problem is to plug in another monitor to your computer. If you are having the same problem it is related to your computer. If the second monitor works fine then your original monitor is shot.

I start my computer and turn it on, and everything looks fine for about 1/4 of a second and then it goes black while leaving the power light green. I can only see the screen again after turning it off and on, but that's only for another 1/4 second. What's up?
I got my rosewill flatscreen as a hand me down from my father. I've had it for several years now. Was working fine until a month ago. When I turn the computer on the screen goes black after 1/4 of a saecond. I have to turn it off and on anywhere from 10 to 20 times before it stays on. I have checked all plugs to the computer and outlets. I have absolutely no idea whats causing this.

Do you get an Amber light on either monitor?
