Question about Dell 1706FPVT 17" LCD Monitor

1 Answer

I have about 4 dell monitors model: 1706FPvt and similar models. They all lost power. Amber light on power button remains off when pressed. Do you think its the inverter?

    So I went ahead and disasembled two of the same monitors and noticed that the capacitors on both inverters were bulging and leaking. Its the same 3 capacitors on both monitors. Specifically the 1000uf 10v crapxon caps. Should I order from digikey? I've been ordering from mouser is there a reason you recommended digikey?

More likely to be bad caps.
http://lcdrepair.us/1706FPVt_inverter-power.html
Also look for bad solder joints.

If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed DELL monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.

You can start by checking the caps in the power supply/inverter board first, or if you do not want to troubleshoot it down to the component level, you can replace the board.

MY DELL IS OPTIPLEX 760SFF, IT NOT BOOTING, SHOWING AMBER LIGHT ON THE POWER BUTTON WHEN PLUG TO POWER.


Hi,
If this the light is solid amber in the front of the computer.Try doing the following steps

1. Disconnect the power cable from the back of the system tower. Press the power button on the tower 30 seconds.
2. Reconnect the power cable to the back of the system tower and power it back on.

If the amber light is on the monitor power button and the tower power button is off or blinking amber it could mean that it is a bad power supply.

I'm not clear about the blinking amber light you are referring to. Is it on the computer or the monitor.
I checked Dell's web site for the service manual for this computer model, & found this document:
http://support.dell.com/support/edocs/systems/dim8300/sm/adtshoot.htm#1102195

If the blinking amber light is on the monitor, check the connection between it & the computer itself. Make sure the cable is not damaged & that it does not have any broken pins in the socket.

Check the 27 mhz oscillator on the back of the main board. Resolder of replace it. It causes lots of different blinking amber lights.

Dell dimension 5150 blinking amber lights


I have similar problem these days. After normal shutting down the PC, it can not be powered up again, the amber light blinks. A temp solution for my case is by doing these steps:

1. leave all monitor, network, keyboard and mouse etc. connected
2. disconnect the power, wait until green light and amber light dim.
3. pop up the CMOS battery, then put back in (better to check its remaining voltage, if not good, change a new one)
4. power amber light flash shorter and lighter
5. disconnect any USB connections like keyboard and mouse,
6. immediately connect keyboard and mouse back into USB ports
7. my pc powers up at this point, all green lights shining. Except it displays CMOS setup warnings, give me options to click either F1 or F2
8. I click F1, it goes into normal login XP

The only problem is I could not shutdown PC again, if I do, then I have to repeat 1-8. I have to use "Standby" instead, which I usually do.

My dell pc still not working


An orange/amber light is almost always a power problem. Is the amber light on the monitor or the PC itself? I'm assuming the PC since you have the ability to read the screen. Your best bet is to check your power supply in the PC. Do you have a power supply tester (about $20) or another PC? You can switch them out and see if the orange light follows the power supply. Let me know what you find out.

No power to my computer.


hi
stuart

just read this carefully.................

Unplug the power cord and the display cable from the monitor. Now press the power button for 60 sec exact. Plug the cables and your system is working................ This is just a power drain.

Enjoy

Is the amber light flashing on the monitor?

If so, you should get your power supply checked.
