Got to the video board and "the 4 capacitors with coils around them" you refer to are actually "inductors" L701, L702, L751, an L752 and I checked conductivity through the solder joints and all is well. Any other ideas?

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.
That problem is usually cause of faulty capacitors on the power supply board..
Just follow this instruction to fix your TV..
1. Open the back cover of your TV. 2. Look at the power supply board..Its normally connected to the power cord.. 3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors.. 4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value.. 5. Some of the capacitors not bulged so its better if have a capacitance meter
loricaney, Do some research first. Go here: http://www.lesliewong.us/blog/2005/05/02/hp-pavilion-f1703-flat-panel-display-blackout-solution/ I just read a comment that some guy wrote. He stated that he aquired 30 Vs17 non-working units from a high school, and that 25 of them had bad (swollen or leaky) filter capacitors. The other 5 had cracked lcd panels. maybe $6 in new capacitors will restore unit for you. Do some reading in my fixya profile and "budmrtn" and "buddymc" fixya profiles. let me know if you want to do a DIY repair after you do research and visit YOUTUBE for video clips of owners doing typical capacitor removal and installation. 12fixlouie
Thsi model has known problem with bad solder joints due to contamination, you need to remove the old solder on the four inductor leads, clean the leads eal well and resolder, see my pictures here: http://s807.photobucket.com/albums/yy352/budm/HP%20F1703/
Al so look to see any one of the capacitors have bulging top, they should be completely flat top.
3 ideas here. bad connections on the coils inside. the inverter board has gone bad, or bad capacitors on the power board or inverter board. all of witch should be serviced by a qualified service center.
My HP f1703 is almost 3 years old and started having this same problem. My fix got the display to stay on. Don't know how long this fix will work. I set the monitor brightness to 51 and contrast to 41. You may have to adjust to your levels to your appropriate enviroment. Levels may determine how long the monitor stay operational. Do NOT set your monitor brightness to factory levels it will just start to recreate the problem again.
The monitor should be on with the blue button lighted. If the screen is acting up (you turn it on and the display lights up and then it turns off within 2 to 5 seconds)
Try decreasing the brightness level down as much as possible. Wait 15 to 30 seconds and see if the display comes back to life. If not, turn the monitor off and on again and try the procedure again, if necessary.
I believe the monitor brightness level, set at 100 by the factory setting, is over driving the display and causing the protection circuit to cut off the flouresent lamps that light the display.
HP had an issue with this display, and had a notice to replace them if the problem occurred during the warranty period. They extended the warranty period from Jun 04 to Feb 06. Check with HP Technical Support to determine if your monitor is cover.
Sounds like cold soider joints on your video board. If you take apart the lcd screen and get to the video board, theres 4 capasitors with cooper coils around it. you can add soider to it. theres 2 pins for each. I fixed 15 or more for that same model. Its a known problem with that model. Hope it wworks for ya
