    Hello Mike,

    I found you gave the IC # of Dell 1901fp LCD, I think you are an expert on it. Now, my 1901fp is power on, but will be blank after several seconds. I replaced the FET (SSS 7N60B) with 7N60, but still same, I heard a noise comes from a ceramic capcitor (103M, 3KV). the power to data board is ok, because I can still see the pics after backlight is off.
    Could you give me some hint or clue where I should check.

Hello, I have NEC MultiSync LCD195VXM+ and when I turn it ON, there is just white shining LCD and nothing else. When plugged in power it came shining ON and after about five seconds its go into sleep...

1. From what you have described this sound as though the video card ( internal) is defective. Most mother boards have video cards on the mother board.
2. use a know good video card and install it to the mother board > there should be ample slots to install it.
3. The OS (operating system should see the installed video card immediately and install drivers if you see a screen then this has isolated the problem to video.
If you don't see any video then you have a defective mother board.

Power supply problem busted fuse

Hello, in most of the new LCD and Plasma TV-s there are special IC-s you can not find in regular stores. Only way to solve this is to contact the Philips Service and order the IC. In most cases the only available items are the complete boards. If you need more info please advice.
