    I solved it, It was an inverter PCB problem, some power supply was not working and I fix it.

    Hi FixinFax,
    I understand why you are angry with my evaluation, let me explain to you:

    I thought you´d let me know where take measures and you did not give me this advice. Giving to you more details of the solution, I found an SMD open fuse ¨FTxxx¨ (I´m not sure about the last numbers 007 or 009) that was on the Mainboard, working like thermal fuse protection for 5 volts from Mainboard to Inverter PCB, so the problem was in the inverter module but in the Mainboard side, as consequence the Inverter was not working at all. I changed this SMD fuse and that’s it.

    ¨You need a fluorescent back light and inverter kit. Available on eBay.¨

    Changing the PCB inverter or backlight would not solve the problem, but for sure wasted money, so as conclusion, your advice was not the good one.

    Sorry FixinFax but you still have too much to learn, please do it for FREE and learn.

The monitor is a Samsung SyncMaster 191T. My cat laid down on the keyboard today and now I am looking at an upside down screen. Can you help me out?


If you are in Windows XP, you can use the following key combination:
CRTL + ALT + up arrow
I am not sure if this combination works in Windows 7.
Good luck.

Unlikely unless you discharged a large static shock into the connector as you were doing this. I have never seen a monitor or computer video port damaged by connecting the cable while power is on.

Try unplugging the power cable to the monitor for 10min or more and then reconnect and see if it starts to work.

You have either a bad inverter board or burned out backlight fluorescent bulb. Very common on this monitor.

Sounds like the invertor board in the monitor is bad or the LCD screen has had it and needs replacing.
