Question about Dell E173FP 17" LCD Monitor

1 Answer

The monitor is a E173FPb - which transistors are we talking about ?

You mentioned 4 transistors that could be the issue of the screen staying black with the power monitor LED blinking Green but you did not state which ones to look for that maybe damaged. Are they the small C5707 ? These are the only one's I can find that are a set (2 sets of 2: Q739,740,759,760).

One set reads short ( .6ohms) between Base and Collector the other set does not. Emitter to Collector reading in only 17ohms vs the other set reads 35 ohms. Seems like an issue but without a schematic it is hard to tell.

Those are the ones, you are going to have to remove them to test as they are across a transformer

Hi there! You can test first if the monitor is working. Disconnect it from the computer then turn it on after that it should show you colors on the screen this means its working if not then its no use trying it on a different computer.


Hope this helps!

Screen goes black, but power light is on (not blinking)


The problem is not with your screen. Its the problem of Video Card of your system which is unable to send Video Signals to the Screen.

Dell Blinking Power Light


Just wanted to say Thank You for the info on this site. I had the same problem as previously posted. When powered up, the monitor showed a fast flash of the desktop and then went black, with the power indicator flashing green. I read the posts, purchased the capacitors and the 4 - 2sc5707 transistors through ebay. I ordered them on the 6th and rec'd them today. I only had one bad capacitor and one transistor that checked bad, but I ordered 5 caps and 4 transistors. When ordering the caps be careful of the height of the caps. I found this to be a problem because I ordered the 50v, 105 degree Panasonic caps that didn't fit with the enclosure attached, so I used the 4 good caps removed previously and replaced the bad one with a 470uf, 50v. 85 degree cap from Rubycon I found among my spare parts. Installed the parts and the monitor is working properly (for the last two hours) so I'm happy for as long as the repair lasts. Thanks again for the info.
