LCD screen totally white when turn on


The HP is a flat screen monitor used with many desktop computers. When the LCD on your HP monitor goes white, it is an indication that your monitor's inverter board has gone bad. The inverter board is a small circuit board that transfers power from the monitor's main circuit board to the LCD screen. Replacing the inverter board means dismantling the HP monitor.

1. Power down your computer and unplug the HP monitor cable from the back of your desktop. Disconnect the power cable from the back of the monitor. Relocate the monitor to a flat work surface. Place the monitor with the screen facing downward.

2. Remove the Phillips-head screws from the monitor's base stand and from the back cover. Lift the base stand off of the monitor and remove the back cover. Peel away the foil from inside the monitor around the internal circuit board.

3. Locate the inverter board near the bottom of the monitor's casing. Unplug the power cables from either side of the inverter. Loosen the Phillips-head screws from the inverter board. Lift the old inverter out of the monitor's casing and set it aside.

4. Place the new inverter inside the monitor. Replace the Phillips-head screws and fasten it in place. Reconnect the power cables to the connectors on each side of the new inverter. Replace the foil around the outside of the main circuit board.

5. Replace the back panel and base stand, and their retaining Phillips-head screws

I hope you find it very helpful.

I have power and sound..no picture


smcclain2, Might be a possible failure of the electronic "ballast" circuit that provides 600 to 1000volts AC to light-up the "cold-cathod-fluorescent-lamps" (CCFL's) hung on rear of the glass lcd panel and provide white light so you can see what is on the panel!! The "ballast" is called an "INVERTER". DCv to AC The new energy efficient curlie-Q screw-in light bulbs use a CONVERTER type ballast. AC to AC. You or ccfl back-lit monitor technician will need to troubleshoot and repair the ballast circuit board. Same "lighting technology" is used in 98 percent of all lcd computer monitors. 12fixlouie

My dell monitor turns on for 2 seconds then goes black and the green light blinks orange


I assume that you already try this monitor on another PC to verify that the problem is in the monitor, in this case you need to open it up and inspect the fuse, transitors, solder connections on the power/inverter board, see failed Dell monitors here for guide: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further.

Ccfl inverter board


The most prevalent failure on these boards are the transformers and or the ic that controls the frequency of the lamp drive. More times than not you will find a bad transformer.

That means that you have a defective inverter board.

The inverter is a small power board that power up the LCD backlight lamp, determining light intensity, when it is like that, the inverter is defective and must be replaced.

Replacing Inverter Board


I did some poking around and only found a few places that sold inverter boards for this monitor. Ebay has one that sells for about $80: http://cgi.ebay.com/Backlight-Inverter-for-Gateway-FPD1930-LCD-Monitor_W0QQitemZ160070918225QQcategoryZ174QQrdZ1QQssPageNameZWINQ3aPOST0Q3aRECOQ3aBINQQcmdZViewItem I wasn't able to find any specific instructions posted, however, taking a typical LCD panel apart and replacing the board shouldn't be too difficult. The only hard part is not getting shocked, which is why this is not a job for the typical user. Anyway to disassemble the typical LCD you remove the pedestal from the back of the LCD then remove the screws around the back of the LCD, remove the back and look for the inverter board. Typically it is covered with a metal shield; again the hard part is knowing how to correctly handle the parts. Considering you can buy a new 17" LCD for $120 to $150 (and has a 1 year warranty) you might want to consider investing in a new monitor instead. If you have any other questions let us know, otherwise please don?t forget to rate this posting.
