Dell 1701FP monitor - power buttons blinking - no display - no white screen

Hi guys, I just got a free lcd panel from a friend who broke it recently. Its been dropped and the screen is cracked, but when I plug it into my laptop as a secondary monitor, I don't see anything on the broken lcd panel. The power buttons just kinda blink randomly - green for the power and amber of the brightness contrast buttons. I am pretty good at experimenting with electronics, so I did open the case up, and found out that the inverter is dead. For this reason, I have another inverter borrowed from a CCFL kit, and I found out that the tubes to burn, and you can see the white glow. But now that the screen glows, and I have the controller board hooked to my laptop as a secondary, when the board is powered up, I still don't see any image, and the LED's on the power button controller just blink randomly. Anyone got a remedy or solution for this?

Re: Dell 1701FP monitor - power buttons blinking - no...

Solution to a blinking orange power light indicator.

Checking procedures.

1. Check the fuse on the inverter board labeled F1. If it is opened then your inverter board has a problem. That's why the fuse is opened.

2. Remove the white wide cable connecting the main board and inverter board. Next plug the D-sub cable and power adapter and test. If the 2 green light indicators are solid green then your problem is positively coming from your inverter board.

Solution in fixing the inverter board:

In my case, the fuse was opened. So I first resoldered all the legs of the 4 transformers. Eight legs each transformer. Resoldered also the capacitor at the back of the inverter board. Checked the 2 diodes labeled (D3 and D13). One of them was shorted. So replaced it using Radioshack 3A 400piv. It is quite bigger in value but I just want to make sure it can handle the load of current.

Tip in checking a diode, it should always open using a digital tester.

That's it. re-assemble then test it again.

I have lost the original power supply for my dell 1701fp monitor. I have a power supply that I think may work as a substitute until I can replace the original. I need to know, what the acceptable voltage...

What ever you use, it must be REGULATED power supply that will maintain 14vdc output, rating at 3A. These regulated power supply can easily maintain the output voltage within +/- 5% with input AC voltage range from 100~240vac.
Linear regulator power supply may not work since it has slow response time to regulate the voltage.

Learn about bad caps:
Capacitors kit: he can make you a set of caps.
Or, just make sure to use caps with low ESR, 105c, high ripple current and long life rating such as PANASONIC FM or FC series.
Please post back what you find.
Please leave rating if it helps.

My LCD monitor is blinking green but no display is coming, some days back after blinking 15-20 minute display comes. But now display not come

Most common failure in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, falied 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 monitors to get some ideas what goes wrong:
Post back what you see inside so we can guide you further.

Dell Blinking Power Light

Hi There,
I have worked on several of the Dell 17" and that is almost always the Capacitor problem.

The caps have died inside, and they can be replaced. If you have basic electronics skills, you can go in, order replacement caps, and unsolder and resolder. If you can't do it yourself, you can take it into a shop.

If you can get inside the frame of the monitor, and disassemble, you can find the caps by seeing a bulge on top, or even a rusty looking material on the top. Be VERY careful around the high voltage section if you do go inside.

Here is a link to the Cap plague that explains what happens in detail. But I repair these all the time with that symptom.

Dell 17" lcd manufactured 2004 wont turn on.

Well first off if its that old the warranty is up im sure. Second they won't deal with you since you are not the one who bought it. I'm sorry I had a similar problem to that altho I had bought the screen and it did the same thing a week after the warranty was up.

Try to do the factory reset. It is on the pop up main menu on the screen by pressing the screen button.

Dell E172FP 17 monitor keeps blinking

That sounds like the backlight inverter board. Check ebay for the board or a repair kit for it.

Monitor (Dell 1701FP) flickers, flashes and goes black

Just to check - when the screen is black- can you see any image- in its un-illuminated state. To do this look sideways along the screen not straight at it. I suspect this is an inverter problem. Whether or not this is repairable I know not- depending on your local repair facilities Perhaps DELL can suggest a local agent.

Everything has a yellow tinge.

Have you tried giving it a good tap on the side? Hey its worked before. Have you tried hooking it to another machine to verify "yellow." Was it yellow on your friends computer? How old is the monitor? Good Luck, Tim

Lines across screen

Is it sort of rolling almost.
If so you have a few bad capacitors in the power supply that need to be replaced.
If you dare to venture inside you should see 1 or more buldging caps. (bowing upwards on the top)
If these start to fail, then they will interupt the correct flow of power and cause this problem with your panel.
Easy to fix if you are electronically minded, if not, take it to your local TV tech and it shouln't cost that much to have repaired.
Remember, inside these monitors is high voltage that can kill, even if it's not plugged in.
