Dell E172FPb 17" LCD Monitor Problem

My dell monitor screen keeps going black after being on for a few seconds. If I turn it on and off the picture is there for about 5 seconds then the monitor goes black. It is definitly a monitor issue, I've put a different monitor on the computer and its working fine, also tested the flat panel on my laptop and had the same issues. I looked for a reset button cant find one anywhere or how you even get the back off of the monitor.It is now out of warrenty and I am not sure how to go about fixing this problem.

Your inverter power supply has gone bad. You will need to replace the whole board or replace the the 2sc5707 transistors in the inverter area. Check out this link for installation videos and how to for that model
They also sell the whole board as well as repair kits

Re: Dell E172FPb 17" LCD Monitor Problem

If your E153FPe comes up for a few seconds then blanks -but left the LED green- it is a case of the inverter board going bad as indicated; I just pulled the power board and I see C922 (1000uF, 16v, 64 degrees C) has bulged out a bit. Perhaps replacing it will work...ah, should've trimmed the leads after soldering. Cool, that was nonfatal. Still gotta remember to plug in the data cable to the panel...aaand, success.

Re: Dell E172FPb 17" LCD Monitor Problem

Troubleshooting DELL E173FPB LCD Monitor with power blink symptom is quite easy if you know the right procedure to test it. There are two sections in the monitor that can cause power to blink. It is either primary or secondary section or even sometimes both sections can be faulty. So to isolate as which section is giving problem. I used an automobile 12 volt light bulb (brake light) and connect it between the 12 volt supply line and cold ground with the fuse removed. If the bulb still blink chances is very high the power primary section have problem.
Do not overlook the other voltages line as well such as the 3.3 and 5 volts. If any components shorted that gets the supply from the 5 and 3.3 volts, the power also may blink. If the 12 volts bulb lights up we can assume that the power supply is working fine and something shorted further down the line that makes the power supply to blink. If the bulb lights and you continue to check the power section, it will be going to waste your time. You should now concentrate on the secondary section circuit such as the four transistors C5707 that drive the high voltage transformer in the inverter board.
Just think these transistors like horizontal output transistor (HOT) in the CRT monitor that drive the flyback transformer where it worked so hard and chances for it to breakdown is very high. Checking the four transistors off board found one of them have a shorted reading with an ohmmeter.. This transistor can get faulty by itself or it could be some others components that caused it to develop a short circuit such as a defective high voltage transformer but all of the four high voltage transformers checked to be okay with ringer and ohmmeter test.
Now, here is the secret that I’m going to reveal. If you just replace the defective transistor only, chances is very high the transistor or another C5707 transistor will breakdown again. Usually what a technician does is to test the other transistors with either an analog or digital meter. If you use both meters to test the transistors then you have missed out on the faulty transistor because both meters won’t reveal to you the hfe reading of the transistors. Only some digital meters have the hfe checking feature. In other words, you have to use test the hfe reading of a transistor. Although you can replace the other three transistors directly, why not we do some detective work to find the cause of the problem?
Using the Peak electronic atlas component analyzer, I could clearly see the different between a good and a bad transistor. A good C5707 transistor has hfe reading from 320 to about 390 but the bad one reads 467! The other two C5707 transistors have reading about 350. In the above case only two C5707 transistors were replaced and you save the other two. I had burn in test this LCD monitor for many days and it worked perfectly fine.
Conclusion- Whether you repair the DELL E173FPB LCD Monitor or any other model such as the E172FPB or E171FPB, basically the testing method is the same. You could also use this testing procedure on other brand of LCD Monitor too.

It will need parts or board repalcement.
Board is only $30,

If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed 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 DELL monitors to get some ideas what to look for:
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Dell E172FPb screen blinking


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 ?
