Re: Dell 1704FPT

Ok PlainBill I did the test and have the results for you. Also to note when I turned on the monitor the LCD lit up and stayed on but was flickering.

A = 457
B = 454

Also my DMMs lowest AC voltage range is 200. R1 and R3 were jumping all over the place.

CF = 0.4
RF = 0.1
R1 = 98.9 to 10.6
R2 = 0
R3 = 8.5 to 9.6
R4 = 0

Do you need me to get a DMM with a lower AC voltage range or will that information work?

Thanks for your help.

Ok, I did the test. I only got a reading when I went from the drain to the source. Three of them read 002 and one read 001.

Ok, here is the picture that was requested. Also the jack on the board is for the power for the add-on speakers.

I will also do the diode check and let you know what I find out....

I recently received a Dell 1704FPT from a friend. The monitor will power up and for a second the backlighting is on. Then the backlight will turn off. If you shine a light over it you can see it is still displaying an image. Also the power LED stays green the entire time.

Looking at the capacitors I can't see any real issues. The capacitors are a mix of CapXon and Su'scon. It's my first time trying to fix an issue with a monitor so I'm just looking for ideas of how to fix it.

So I guess a question is should I just replace the some or all the capacitors? Or from my...
