    Westinghouse LCM-22W2

    Greetings and Happy New Year to all!

    Thanks to these forums I was able to fix my failing aging monitor. Display would work when it wanted, had to do numorous reboots plug pulling just to get it to power on. input names were distorted...well after reading up and researching it was bad caps on the power board. I ordered a replacement kit on ebay turns out to be a fairly well known company..they provided everything I needed pretty much in the kit...well after replacing all but one very tiny cap (looks to be in fine shape) the monitor worked again. input names are readable and the monitor powers on just fine like day one.
    As of yesturday the monitor stopped working. it powers on but after displaying the input name for just than under a second the screen goes black..power led stays green to show that it is powered on but there is no image as if the screen was powered off....not even a faint image as if the backlighting was going out... I am now at a lost and not sure what to do.
    I already reopened the monitor and resoldered a questionable point. but still no luck.

    Any suggestions?

    Re: Westinghouse LCM-22W2

    Hmmm ....

    1. Some pics of the board top & bottom?

    2. Should be a Delta DAC19M009 ?

    3. Try a flashlight to see if faint desktop image can be seen ?

    4. Check fuse F200 ?

    5. Check if secondary voltages appears and is within range ?

    6. Check mosfet U202 & U203 for shorts ?

      Thanks for the quick response I can reopen the monitor again and snap a few pics...not the greatest soldering job but it worked for about 2 weeks
      step 2 I am no electriction so i have no clue about it being a Delta DAC19M009
      I just tried the flashlight trick again this time using the led app from my phone and crap now i do the wallpaper i guess my other flashlight wasn't strong enough to show me the display.

      not sure about these two steps....
      like I said i am no electrictions but i know computer components very well
      4. Check fuse F200 ?

      5. Check if secondary voltages appears and is within range ?

      how would i be able to fix this backlighting issue?

        Yes looking at the board now..this is true.

        3. Try a flashlight to see if faint desktop image can be seen ?
        yes noticed this

        4. Check fuse F200 ?
        Not sure where to locate or what this looks like

        5. Check if secondary voltages appears and is within range ?
        Not sure how to do this
        6. Check mosfet U202 & U203 for shorts ?
        Not sure how to check this as well.

                    Is that small cap CE107 or something like 22uf 50v? It's a critical cap for starting up the power supply and you cannot determine whether a cap is good or not by looking at it. If you have another cap (that you know is good) lying around that you can substitute on temporary basis, then at least you have a good starting point.

                      Re: Westinghouse LCM-22W2

                      22uf 50v is correct. it was the only one that I didn't replace and to be honest because of its size and placement, I was pretty intimidated by it. If this small cap can cause the backlighting to go out then i guess i can give it another shot...just hard trying to get the old solder off with the copper strip.

                        Re: Westinghouse LCM-22W2

                        I suspect that cap also.

                        It is often easier to get the solder to melt by adding some leaded solder
                        to before trying to mop it up.

                            It can also help if you pre heat the area of the board you are working on with a hairdryer - so the heated is conducted away less quickly

                              thanks for all the advice ... I did as recommened and replaced the small cap...Problem now is that i think i screwed something up...i double checked all solder point again and everything appears to be OK. small cap looks to be in correctly as well, but now I get nothing just the power light. I get a few short flickers (no display of the input as it did in the past) and thats it just a black screen, and power button no longer functions.. not sure if i shorted something out or not.

                                  in to the power supply?

                                  I goofed and FORGOT to take a photo...

                                  Also, did you solder the 22uf 50v cap, if so,
                                  was it the small silver looking one?

                                  thanks

                                    Normally, I never post repairs this quick after I do them, because… I am usually very slow. But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

                                    Quick specs: 22” CCFL backlit LCD, 1680x1050 max resolution (16:10 aspect ratio)

                                    I got it with a bunch of desktops PCs from a repair shop that was trying to free up space a few years ago. It seemed like a cheap monitor, so I didn't really care that much at first when I picked it up (and indeed it is, picture-wise.) But hey, free is free, so I can't complain. Moreover, it looked clean and the screen didn't have any significant scratches or blemishes.

                                    Lately I am experiencing the deja-vu incident on one of the led monitor like this.

                                    The monitor will randomly blackout and display no signal and will recover again.

                                    Good evening, gentlemen.

                                    I have a problem with my monitor. It turns off after a few seconds or flickers. Shining a flashlight on the screen doesn't show any image, so I guess it's not the "2 seconds to dark" I read in the forum.

                                    To turn it back on, I have to press the power button twice. Then after a few seconds it turns off again or flickers. See video.
