I would expect the same (new) part failed. Try another dual diode otherwise you may be chasing the problem around the board.. Good Luck, Tim

SOURCE: Dell 1800FP Dark, No Power but power supply seems fine. Help!

I just repaired 3 1800FP's - all dead, no lights.
Firstly a dead 2AS01 is 95% of the problem, because some fool designer left out the protective zener diode - cheapness.
Mouser Electronics does not have this part, but lists it at 37 cents in lots of 2500, and gettable at $2.66 somewhere else.
You must also replace the two small value electrolytics near this IC, as some had an ESR of 40 where <0.5 is where it should be.
I suppose as the electro's dry out, the spikes can zap the IC. The quacks on ebay flogging 2sa01's alone, probably hope to sell you another one down the track (at a fat markup).

There are 2 'Sam Young 2200uf' electros that really should be replaced, with ESR or 2-30 ! Ideally replace ALL electros, as the others will be off - but those 4 as a minimum and using a jewelers loupe, resolder other joints on the transformer and anything that looks more dull silverish, than the rest. A 1 inch used and worn paint scraper will get the case open easy.

DANGER, CAUTION : Finally when refitting the inverter board, ensure the steel tab is over the TOP middle of the board facing away from the power socket (SO YOU CAN SEE IT) . The board sides in flat. It is possible to scew the board down with a slight bend, with the tab pressing over the pcb tracks - very , very bad!

Now all I need is for some kind soul to improve the fix by stating what the value of the missing zener should be.

PS. Just because the caps are not bulging does not mean they should be OK. Most wrecked 10 year old power supplies have better ESR's, so the electronics must be hot under the cover.
I have seen bulging caps with a GOOD ESR, and non bulging ones with an ESR of 47.

two case trouble reason and need to do:
1) back light driver (inverter) works not stable and DC power protect. it near some component damage, should repair inverter by egineer.
2) back light (lamp) over life cycle so protect by the inverter, should change new lamp (regular parts)
3) DC power supply not stable or component over life( wave filter capacitor), should be replaced

Power failure is likely caused by faulty diodes in the power converter inside, I have replaced these on led flat monitors a fairly easy and cheap fix, be sure to use quality Japan made gold diodes which can be had for around $25. The hardest thing for me was getting the outer case apart then it was a snap but Don't attempt to use anything but a cold tip soldering iron or you will damage the circuit board that holds the diodes.

Dell ultrasharp 1907fp bad contrast


I have seen a few of these monitors that when the display is dark in certan area's this usually indicates that one of the CCFL lamps has gone bad or there is a problem with the Analog/Digital Board, you can find the boards on ebay, but be VERY Certain that the board you order is the same that you take out of the monitor, as there are a lot of monitors that use the same simular boards but they are all different.

You can start by checking the caps in the power supply/inverter board first, or if you do not want to troubleshoot it down to the component level, you can replace the board.

Dell E173FP shows nothing


The backlight may have died. LCD monitors work by shining a light through the active diodes.

You could have an inverter board problem. The inverter supplies high voltage to the CCFL lamp which provides the back-lighting.

There screen will not switch on and the power light is flashing


This was the same symptom on a Dell 19" LCD monitor I got and after disassembling it found a
shorted transient absorber diode (ZD15) on the power supply board. This diode is a protection diode between the 5V and 12V output. You do not need it
to be in the board but if you want to keep the same
protection on the board I suggest you order a
replacement from Digikey.com or Mouser.com.
You will need to know how to separate the front bezel from the rear casing to get to the power supply board. I have a picture of the power supply board and the bad part is at the bottom left of the board with the designator ZD15.

Dell 19" monitor screen turns blank


i had same problem, fault was traced using a multimeter set to diode measurement, i found that one of the high power switch transistors in the inverter side of the power board was short circuit (there are four in the same area sticking up from the board, not surface mounted). normally they should measure 450 ish but when they read 0-010 its gone, pulled it out of circuit and remeasured it, gone, replaced and fixed.
