Question about Dell E153FP 15" LCD Monitor

1 Answer

I have a dell monitor E172FPb monitor and all it will do is the power button flashies green. I have read forums that refer to replacing the four transisters on the logic board but state that is no quarantee. It seems that the whole logic board is rather cheap (40.00 on Ebay) would that probally be the best route to go. I am a technician but I don't have the time to spend hours testing parts and trying to get off cheap like spending 2.00 at radio shach for transisters. Love advice Thanks

I have a Dell E172FPb LCD monitor with a black screen and blinking power light, no leaky or swollen capacitors inside, what can I do to repair it? Thanks.


Check out the four transistors (c5706/5707) Emitter to Collector (see picture of the transistor in my transistor album for pinout), it should read open circuit (should be checked out off the board). This is common problem. Make sure to inspect the solder joint in on the board, especially around the inverter transformer pins. Make sure the fuse read out less than one Ohm also.

You need to open it up and inspect the componente inside, look at the fuse and the transistors in the inverter circuits first, also look for sign of over heating on the board, see pictures here for the guide: http://s807.photobucket.com/home/budm/allalbums

There are two possibilities, one is bad caps in the power supply, number two is shorted out transistors (P/N c5706/5707) in the inverter circuits.

10-30-2007, 07:54 PM I have the same monitor and it had the same problem, I got it for $10 at a garage sale because they "didnt know if it worked or not" BS, they knew it was broke. But i accepted the challenge. There are four transistors on the power supply board detailed as Q759, Q760, Q739 and Q740. It is usually just two that go bad on these monitors, but instead of hassling with testing all four, I would recommend just replacing all four. Here are some replacement part numbers. I used NTE2524, same as NTE2525, and paid about $1.25 each.
and here are Sanyo parts (hard to obtain):
2sc5707 C5707
2sd1803
2sd1804

ECG2524

The transistors are rated at 60v 20w.

Just wanted to share my success story. Hope this info helps someone. I found my info on some other forums that i can't find right now.

#1 Connect monitor to another system, make sure the issue is the Monitor, not the video card.
#2 Try a different VGA or DVI cable

Dell E172FPb screen blinking


Hello,

If you've tested turning the monitor on without the VGA cable and it's still blinking I'd say there's a problem with one of the capacitors on the power supply card on your screen, when you're able to check it would you mind telling me the brand / reference of it ?
