Monitor - how to remove back to check fuse?

Geewhizz on 23/04/2014 - 07:40

So long story short, my LG Flatron W2242T monitor was working fine one day. Next morning when I went to turn it on, the button flashed blue for a fraction of a second then nothing.

I'm wanting to remove the back to see if there's something as obvious and simple as a blown fuse before going out and buying a new one (not planning on doing anything else) but there are no visible screws holding it together. Is there anyone who can tell me how to get it apart properly please? I know hubby's way of doing it will be trying to lever it apart, hoping to jag finding the lugs that probably hold it together.

No lectures necessary about messing with electronics please, as mentioned, if it's not something that is visibly obvious from the start we won't be doing anything else to it.

    See if you can locate a service manual on the web.

    I suppose it hasn't shown any sign of ever waking up again? I doubt it will be as obvious as a fuse. More likely the switching mode power supply decided to quit working for any of a variety of reasons, none user serviceable.

    fuses blow for a reason - there will be some underlying problem. most likely a component in the power supply board will have failed. bulging capacitors (defective) are common

      Agreed.
      Still worth replacing the caps if you have the skills.

    Hmm ok, thanks. Might just scrap that idea then.

    well it won't hurt to have a look. if there aren't any screws then you need to pry the front fascia moulding off. if you scour youtube you will probably find some videos of people disassembling similar monitors

    Not related to the OP's question but I have an LG 24" 1200p monitor that exploded, basically I turned it on and it made a massive bang and turned off. Would it be worth trying to fix? It's just sitting here and I was about to throw it out.

    • ESEMCE on 23/04/2014 - 13:58

      Unplug it, pull off the back cover and try to ascertain what precisely went BANG!..
      A bit of googling ought to tell you if it's a common problem and if there's a cheap fix.

    I have this monitor. Still works, it makes a really, really irritating whine whenever the brightness is set to anything other than a full 100 percent.
    Probably made with uber cheap parts.
    I think that's part of the reason the LCD broke, because the inverter blew up.

    I'd sell it to you for real cheap, but the cost of shipping it to you will probably be worth more than the LCD itself.

      Umm thanks scrimshaw. I'm not really into iritating whines in my machinery (or in children, come to that) though.

      Based on some of the previous comments I'm thinking the capacitors are well worth checking out. Still working on getting the casing open at this stage though. lol

    Does anyone know if this site is reliable?

    No, just no. Save your time and just buy a new one.

    • Geewhizz on 24/04/2014 - 19:25

      lol Just realised how that post may have read - wasn't considering getting the manual for use in trying to fix it, just to get it apart. Ended up getting it apart via a you tube video though.

  • Geewhizz on 24/04/2014 - 18:38

    Finally managed to get it apart, and there were 3 blown capacitors. Replaced them and it started up fine, but picture was a bit fuzzy, so giving up now. Thanks all for your help.

    This model LG monitor is SHIT, it was repaired twice with same problem and after warranty expired it dead again with same problem as OP. NEVER EVEN PURCHASE ANYTHING FROM LG AGAIN. LG=Lots of Garbage. OP should file this to ACCC as product defect that should be recalled by LG.

    • Geewhizz on 27/04/2014 - 09:06

      I've actually had mine for a few years now, and no problem until now.

      If I were you though, given that it was repaired twice under warranty I reckon you would/should have a good case to take to fair trading.

      I only paid around $129 for it on clearance at BigW. I'm just spewing that it's going to cost me so much more to replace it. lol

        The second-last VCR we bought back when was an LG and that wasn't exactly a paragon of electronic or electro-mechanical engineering, but the three LG computer monitors still in the house - including a W2242TQ (slightly different model?), have been amazing.

        Now re-purposed as TV monitors connected to old set-top boxes, all are about 5 years old, and all have had an enormous amount of use. Still performing as new.

        Everybody gets unlucky with individual pieces of tech.
        Contrasting to you, sonyy, two of my worst experiences have been with Sony-without-an-extra-'y' products.
        A TV that didn't last anywhere near as long as I'd hoped/expected, and a hi-def set-top box (that when first sold cost $700), that only just made it past the warranty period.

        Swings and roundabouts.
