Dead Dell SE197FPf LCD monitor

Completely dead - no LED in on/off switch. Suspect power supply, however, first problem is how to get the back off without damaging the plastics - does it need a special tool? There is a rectangular hole about 3mm x 8mm with a picture of a lock next to it - is this something to do with it?

SOURCE: Dell E173FPc 17" LCD Monitor Problem:

Although similar, this monitor and the associated repair is different than the "b" version. The link above is good to follow for finding out how to open your case but the actual repair is different. If you have minor soldering skills (really the de-soldering is the hard part) and can use a phillips screw driver you can make this repair.

I contacted Tom at a link I found on the "b" site and he sent me the typical components to fail for the "c" monitor. $20 and $1.35 for shipping. The site looks to be down now so I'm not sure if this is temporary or he's stopped selling parts. He is also willing to fix the board if you send it to him. Here's what you need to do:
Replace C922 and C923 with 1000uF 35V caps
Replace c924 and C925 with 470uF 25V caps
Re-solder L201 and L202 with fresh solder.

I did all of the above and the monitor works perfectly. When you take the monitor apart make sure you note where the blue and pink wires go (you'll know what I mean when you get to that stage). The connectors are identical and it would be easy to forget which way they were installed.

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.

I have the same problem. I talked to a few people and it is believed that the condition has been caused by a power surge.
My monitor is out of warranty, so I intend to open it up to check the fuse(s).

I will post result of that soon.

SOURCE: My dell e173fp monitor has quit working. The

Is the power blinking amber? This is a DPMS power-save mode. With the computer disconnected and the monitor on, do you see the colored self-test block floating around? With the monitor on, computer connected, and you still have no image displayed, take a bright flashlight and examine the screen closely. If you can see a very dim display in the screen, the fluorescent tubes which light up the *background* and provide the vivid picture(sort of like a how an x-ray picture viewer works) are defective. The power light blinking may be the power supply sensing the non-functioning tubes or it could just be bad. If your display is under warranty, replace it. If not, trying to have the monitor repaired for this type of problem is almost as costly as a new one--and there won't be an active warranty on anything else that might fail. Hope I helped you.---Rick

My scepter e240 wont power on is it junk or what


dear,

first of all, check whether the power on/off button light (LED) turns on or not. If it goes on either orange or yellow/green, it means its not completely dead. If its not doing that then its a different matter.
Then you have to check the power cord that can be problematic and need replacement. If it is ok then you have to disassemble your monitor to check the inner fuse that is related with the power supply.

Most probably it is cause by the Capacitor, if it is dead and after checking the fuse!

best of luck!

Benq 567s lcd monitor does not power up. Switch led blinks but goes dead. Tried replacing capacitor 450v 82uf with 400v 100 uf but did not work. please help.


That cap is for the Primary power supply switching circuits. How is the DC secondary side, no blown fuse, shorted transistors in the inverter circuits? Pictures will help, budmrtn@aol.com

It may have the same bd as DELL since BenQ makes monitors for DELL and HP.

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

Dell monitor e17s fbp.. wont turn on


Flashing power LED light means you may have shorted (Emitter to Collector) out transistors (c5707) or bad fuse (fuse has high resistance) PF751. Those are what you need to check. see pictures here: http://s807.photobucket.com/albums/yy352/budm/Dell%20E173FPb/

Monitor just went off. no power light. changed fuse but monitor is completely dead


possibly a power surge killed the main board in the LCD. if the fuse was blown i would suspect a power surge. you could replace the circuit board. either that died or the power supply died- depending on if it has internal or external power supply that might be blown as well.

i would take it to a professional LCD/ LAPTOP repair person. they should be-able to test it and let you know what needs to be replaced

Dead monitor dell e173fp lcd monitor


This could be either down to an internal fuse blown or the main board or the capacitor on the power supply could be faulty.

Dell E197FP LCD Monitor won't turn on completely dead


could be dead, but check to ensure that you are using the monitor ONLY, not TV tuner device. as a standalone, not hooked to cpu if there is no power light when plugged in assume your buying a new monitor.

Monitor won't turn on, no led.


If the LCD has an internal power supply, then the inverter circuit should be on the board as the power supply. If the power supply is external, then the inverter circuit will have it own board.

What is the output of the Inverter circuit? It should have 12VDC going in, but around 50VAC going to the CCFL bulbs.

The "no led" should be a sign. Your getting voltage, but what about current? It still can be the power supply. All LCD monitors should have a "soft switch", or software driven switch to turn the CCFL lamps on and off.

It is hard to find literature on LCD repair, experience is the best teacher on this subject. This might take several emails or postings to help find the answer.

LCD monitors are a computer. You can break them into several parts, Power, I/O, and processing. Power is the easiest to trouble-shoot and repair. Processing is the hardest.

I fixed one LCD monitor by re-seating the software EEPROM. The process could not do its job if it can not read the software EEPROM.

If one of your IC's is shorted, you can always tell using a can of air. Get one of those cans of air and tip it upside down and spray the entire board until it all turns white. Now apply power to the system. If an IC is shorted, it generates more heat than anything else. It will be the first to loose the white condensation. Don't worry this is safe, done it several times.
