Have you checked your computer? Does it turn on when you press the power button? Does the power button or lights in your computer lit or is it blinking? Can you still see the Toshiba logo or nothing (just blank)?

You have two possible issues here:

1. Power issue
2. Computer part problem.

You need to check both. Start with power issue. Check if computer is getting any power.

Let me know

    Since the LCD is changed so it has something to do with the connection between your LCD and your computer. If you can check the motherboard port for your monitor for damages or any sign of defects. Have you tried using an external monitor? Does the external monitor work?

Hi, I have a ViewSonic VX2235mw LCD Monitor it was working fine then all of a sudden the screen turned off and now it wont turn back on. The power light is on and is Blue but no sign of life in the screen...


Hello,

This is a very common problem with this model after a few years of use. This problem is caused by a failure of the capacitors in the power supply board hat powers up the back lights in the monitor. When the back lights don't power up you get no display on the screen. Here is a link to a repair guide for that model that shows how to open the unit and what to look for and replace to repair the monitor.

I have a 17" LCD Monitor - LCM-17V8. When I turn


Hi, it seems to be an issue with your monitor's backlight not working properly. Just to be sure, try using a different monitor on the same exit of your VGA, if that works, my supposition is confirmed. In case your monitor is still under warranty, just send it to Westinghouse support center, otherwise I'm afraid you will have to buy a new one. Hope it helped, Franz

No picture.. just a bunch of random colored lines


It sounds like the T-CON board on the LCD panel may be damaged when the filter caps went bad. Do you see any bad caps in the logic board? Also check out he ribbon cable between the logic bd and the T-CON LCD panel are properly attached.

My LCM-22w2 monitor will now rarely start up. It powers up white-screen and won't do anything. Occasionally it powers up OK and works fine.


wford451, You should open up the unit and inspect the "switch-mode-power-supply"/"CCFL inverter supply" printed circuit board for the common 2 problems that create symptoms like yours. Do some reading in my and other CCFL back-lit lcd monitor technicians fixya profiles. They are loaded with solutions to fix your unit. Your LCM 22W2 is no different than any other brand in it's basic design and operation!!! 12fixlouie

Se w880i - phone starts then wont show anything on screen


Ok, so whoever said you need the flash, shold flash their brains! Your backlights are burnt on the LCD - to change it costs about $80 because you need a new LCD screen at the same time.
