Question about Dell UltraSharp 1907FP 19" LCD Monitor

1 Answer

Dell 1907FPt picture appears for three seconds, then off, LED power remains

My Dell 1907FPt LCD was the victim of a power surge. Now the LED powers on and the picture appears for three seconds then disappears but the power LED remains green(not orange). I can repeat this every time I power it on and my ear to the back reveals a slight crackling sound before picture disappears. Is this something I can fix or do I need some professional help here? How does back get removed? I unscrewed the four visible retaining screws and gingerly tried to pry back off. Am I on the right track?

    We have the same problem - power on, screen comes up for a few seconds then goes black yet green On light stays lit. Can repeat by powering Off then back on. This was an expensive upgrade when I bought my system a few years back and I hate the thought of having to dispose of the monitor if there is a known fix.

    I've just picked up a 1907FPt for free, with the same problem... I've had a look inside; no dry joints or any obvious electrical damage to any of the components.

    I've read either here or on another forum that it's down to the inverter. I work in an IT helpdesk, and we use these monitors at work, so I'll have a chat with the hardware guys and see what their take is on the problem tomorrow... If I come up with a solution, I'll post it here.

    More than likely I'll have to order a new inverter, chances are I should be able to get one through work, but we'll see.

    We have the same three second blackout. We change computer to rule out any bad cards or time savers.
    No luck

    I too have the same problem. Comes on for about three seconds then goes off but by looking really close I can see the test screen floating around. The monitor is not hooked to the pc to check if it was the video card or the monitor. HELP!

    This is not a power surge problem, I have the same problem with a 1707Fpt three seconds and then it blanks out. I've checked the cold solder joints and retouched many of the shotty looking ones but to no avail. The caps all look good, it's possibly the IC's but I need someone who knows more than I do to have a look. I've got three of these monitors all with the same problem which means more will come. The inverter board is a cop out there are only two boards one is the video the other is everything else. So yes if you change everything else you're likely to find the problem.

I have the same problem. I talked to a few people and it is believed that the condition has been caused by a power surge.
My monitor is out of warranty, so I intend to open it up to check the fuse(s).

I will post result of that soon.

Sony KDL 46HX820 turns on, then off and red light blinks four times.


Re: Bravia KDL46EX720. Red LED blinks 4 times and TV wont turn on. What is the problem?

Do a Power Reset.

1. Turn off the TV.
2. Unplug the power cord of the TV from the electrical outlet.
3. Let the TV remain without power for 60 seconds.
4. Plug the power cord back into the electrical outlet. (If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.)
5. Turn on the TV.

If the issue still persists after performing power reset, that may be an indication that the TV needs service. You may refer to this link to locate the nearest Sony authorized service center in your area.

HOw to replace the power fuse in a OCOSMO LED TV


There is no replaceable fuse.
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.

DELL 2208WFP LCD-Comes on normally, but almost immediately goes dark You can see something on the screen if you look closely. Turn it off and back on you see it then dark. any help?


Hello,

I believe the power led button is still on while the screen goes dark, if yes, it means the picture board of your monitor is bad that is why it appears for a second and goes dark after that

Since the power led button is on, It means the picture board on your monitor is faulty that is why it appears for a second and goes dark.

The best thing for you to do now is to take the monitor to a local repairer or any service center within your vicinity to help with the replacement of the picture board because the fault is not something you can fix yourself in other to complicate issues.

Take care.

I have dell 1907fpt, the lcd screen powers up for just 2 or 3 seconds.


The backlight might be bad. As far as I know, there isn't a way to replace that, so you'll have to get a new monitor.
