Question about Dell UltraSharp 1704FPT 17" Flat Panel LCD Monitor

Display lights up then quickly goes dark

I googled this problem a while back, and somehow I found an article saying that this is a frequent problem with the backlight inverter with this model, but have been unable to find anything about the problem since. What happens is, when I turn it on, the display will quickly flash what I should be seeing, then it goes dark.

It could be your LCD backlight giving you problems. With the computer on and the monitor power LED green shine a flashlight in the lower left hand corner of your screen. Look for the ?Start? button, if your backlight is not working you?ll see a faint ?start? button if you look closely. If you do see the ?Start? button then either your backlight tube is bad or more often the inverter board is bad. Let us know if you have any other questions and please don?t forget to rate this posting.

Hello,
You most likely have a backlight issue with this TV set. Could be the inverter circuits for the backlights. The inverter is the power supply source for the backlights. there could also be a screen driver problem. This would entail changing the entire board. You should call in an authorized LG repair center to check this set out for you. Good Luck and please let me know what you found out about this TV set.

Where can I find instructions for replacement of the backlight inverter?

It's hard to find a step by step instruction on how to replace a busted backlight because of different model concerns.

If somehow you manage to get through on your lcd mainframe with careful disassembly of the back cover.. then you should watch this. A 2 part recorded video on how to remove a backlight inverter for a laptop. And a video on how to Install a laptop inverter here are the 3 links:

Hope you learn watching.
Much appreciated if you rate this help.. thanks

How to FIX

Televisions have protection circuits which prevent full power-on if a fault is detected in a high voltage/high current circuit such as the backlight inverter.

Some googling on 'Sony Blink Codes' found that 4 blinks is 'backlight failure'. A common failure in LCD displays is the backlight inverter board which is a transformer similar in function to a fluorescent light ballast, as the backlights are fluorescent lamps.

If the screen color is getting pinkish/reddish, that's a sign that one or more of the lamps themselves are going bad.

Since multiple lamps are connected to (typically) two inverter boards (a primary and secondary board), I am fairly certain that the blink code refers to a failed inverter board and not a failed lamp.

Gateway inverter board replacment

Hi,
The inverter board is the circuit board inside the screen, with all the capacitators etc that controls the backlight. It looks like this:

your problem is a faulty ccfl BackLight Inverter, the display uses the backlight to illuminate the lcd screen, the inverter is used to illuminate the cold cathode light in the back of ther lcd theirs countless places to laern about it on google.
They are cheap to replace google your model with inverter at the end..

The backlight is dead thats why you can only see when in the sunlight.
