Purchase new transistor of original company duplicate transistor may heat and burn solder the capacitor of same value solder fuse and better to work on series lamp protect from burning if transistor burn again then check zener and replace if faulty

In a dell e177fpf lcd monitor all the capasitors fuses diodes in power supply and inverter board are ok.but the back lights remains 2 seconds.


Hello...I recently opened up my Dell E173Fpf monitor because the screen went black, yet the power button was green. I thought it was a capacitor problem. But before doing anything I gave the board a thorough inspection, looking for anomalies. I observed a substance, (later identified as silicon) puddled around the power connections. I gently removed the semi rigid stuff and didn't touch the capacitors as I had originally planned. I partially reassembled the monitor for a test run and it worked again. (Being 9 years old, I don't know for how long...) Only thing I can think of is that a spill happened at the factory and over the years it gradually "melted" to puddle around the wires behind the power input. (Weird, but that seems to be what happened.)

My dell monitor turns on for 2 seconds then goes black and the green light blinks orange


I assume that you already try this monitor on another PC to verify that the problem is in the monitor, in this case you need to open it up and inspect the fuse, transitors, solder connections on the power/inverter board, see failed Dell monitors here for guide: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further.

When I connect the power to the monitor Dell E173FP 17, power bottom commence to turn on and off repeatedly...


Power LED is turning on and off because the power supply is in shutdown-restart mode becuase it sensing over current draw, it can be bad caps in power supply, shorted tramsistors (c5707) in the inverter circuits. See pictures: http://s807.photobucket.com/albums/yy352/budm/Dell%20E173FPb/
Check the fuse and the transistor out (check Emitter and Collector pin for short circuits)

Heard pop and had burnt smell from DELLE207WFP.


Hello

The pop you heard was probably a capasitor. If i am correct the smell will get more prominet how longer the screen is on.
If it is a capasitor, which i believe it is, it will not be expensive at all to repair. Just take it to an electronic repair shop and let them just put in a new capasitor. The vapours of the smell is not deadly fo the small amounts of time and the concentration you are inhaling, but it gives me headaches.

Please rate this.

Best regards

No display, clipping sound appear


The clipping sound is the internal safety switch that keep shutting down the monitor.
It means there is an internal problem on the main board (overvoltage, bad component , short).
Try unplugging power cord and leaving it unplugged two or three hours, this will reset ICs by draining power completely from circuits, it is called hard reset, it rarely works.
CRT monitors waste up to 15 times more energy than TFT screen, if your CRT starts giving troubles, then it is a good time for upgrading it to a new TFT.

BenQ FP71E 17 goes black during post


Hi...there,
With AC adapter it's to your left, a rectangle piece. Without, it's under you power supply w/ built-in inverter... the capacitors look like a tiny battery on the side it have voltages size ( example like 1000uf 16v ) Good lucks, have a nice day!

Same problem


You may not even have those capacitors on your board. All boards are coded differently according to whoever manufactured them.

Here's a site with pictures that address's this issue and will give you more insight on this problem.
