Question about Dell E173FP 17" LCD Monitor
I have a Dell 17" LCD E173FP, that has a blinking power light on the power button. When I plug in the LCD, no other lights come on, and the power button starts blinking. The screen also stays black. Any Ideas anyone? Thx guys and gals.
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.

There are 4 transistors that go bad due to various issues (one being a cold solder issue with the power inverters for the transistors. I had this fixed and replaced the transistors. They lasted about 10 months). The 4 No. 2SC5707 transistors must be desoldered and removed, new ones put in their place and resoldered. I took the parts (transistors) and the removed power/circuit board from the LCD to a tv repairman and he did the repairs (de and resoldering) for about $60.

I just fixed one of these, and it was one bad cap. Also I put a heat sink on the 4 transistors as they had no heat sink at all. I soldered
a small piece of tin to the back side of each one, and bent it over
out of the way.

There are 4 transistor C5707 these go bad from heat and cause the high voltage to the back light to shut down.which cause your monitor to hangin the sleep mode blinking light there also may be bad filterig caps look for bubble on top of cap it is very common with dell monitor these are really benq monitors made for dell i repair these every day.

When it have this kind of error is a problem of the powerboard.
Anyway you must open it and look at the all capacitors and if are them inflated, if them are inflated must change them.
But can be a problem with inverters... control the transistors - MOSFET on the powerboard.
