    Dell E172FPb/173FPb 17" monitor. screen + pwr led blinking

    The monitor is a Dell E172FPb/173FPb 17" (has both E172 and E173 on the back...).

    The problem is that it doesn't work, when plugged in and turned on it just blinks once every second or so, and the power LED blinks along with the screen. As if it's constantly restarting itself.

    The other problem, is that I've searched these forums, and when I find the same monitor, it appears to have a different board...

    I'm a newbie to working on monitors, so any help would be appreciated.


    I would have uploaded pictures but I guess I can't do that on my first post? "Your submission could not be processed because a security token was missing."

    Regardless, I'll get them uploaded some time soon, maybe use another website for them...

    Note the instructions and size limits below in my sig file. We want clear focused top down view of all your boards.

    Please upload the pictures here, not somewhere else.

    If you are new to this forum, we can help a lot more if you please post clear focused pictures (max resolution 2000x2000 and 2MB) of your boards using the manage attachments button so they are hosted here. Information and picture clarity compositions should look like this post.

    We respectfully ask that you make some time and effort to read some of the guides available for basic troubleshooting. After you have read through them, then ask clarification questions or report your findings.

    Please do not post inline and offsite as they slow down the loading of pages.

      Ah, I see. Max size 2 MB. What's listed in the attachments upload section is incorrect "jpg 3.81 MB 2000 2000"


      Hope these are good, had to reduce the quality to make them under 2 MB... lol

        Excellent pictures, The classic cause of these symptoms are transistor pairs Q739-740 and Q759-760. Check these for shorts. If any of a pair are shorted replace both. Also resolder the transformer leads and the leads on caps C735 and C755. And check Q781? (between C763 and C794) and it's mate to the left of C751 for shorts.

          There's a gent selling repair kits on ebay for your board for a good price. He's sold over 1400 of them, which should tell you something! Also, remember to resolder all the pins of the 4 small yellow inverter transformers.

            I have this 173FPb .. originally it would turn on for 2 seconds, and then blank, power LED on.

            I got a similar replacement kit from ebay, replacing all 6 transistors : FU9024N x2, 2SC5707 x4

            But now after a few days after replacing them, I get the screen & LED blinking.


            edit: well, now the 173FPb is on & working. It only started to flash after I 'woke up' my PC. After being unplugged for a some mins, its working now.
