    Lg 226 wtq

    Hey there bad cappers.Here's the back panel Of my monitor. As you can see, it's about 8 years old. Earlier this week it seems like my monitor started to die. I want to see if you can confirm my suspicions that it's capacitors (and maybe provide some assistance on replacing them)

    The symptoms started after doing some PC upgrades, but i've since narrowed it down to a monitor issue only. At first, when i'd wake up in the morning, I'd go to wake up the monitor, and the monitor would respond, but not actually show an image for ~30 seconds. The power light was blue (indicating it was powered on, and connected to the PC), and there was no "check connection" style message. In use, there was no issue with the monitor. Fiddling with power and DVI cable would eventually turn it on. This morning, I go to do the same, and there's no response, until i get what seemed like a solid white flash a couple of times.

    I haven't been able to actually open up the panel yet. Following these instructions, I have the screws out, however I'm unable to pry the front bezel off, even using a flathead screwdriver as leverage.

    So, the first question is, does this sound liek a cap issue to you, and secondly, are there any other hints to getting the frame off this monitor to get to the inside?

    it might be bad caps
    seeing the board would tell

    he may have had that trim off on that video which might be why it came off easy
    some are a real pain especially at the corners.
    try taking an old credit card and sharpen an edge so that it is like a wood chisel . you can do this by rubbing it on a concrete floor or using a nail file. Then work that between the front frame and rear case starting in the middles and while rocking the front away from the lcd screen.

      i'll second that,
      getting plastics apart is easy if you use something worthless like a bank or satellite-viewing card.

          ok so this is where I'm at, however, i'm hearing what sounds more like a "tearing" than a popping sound, and it's scaring me to hades and back. Is that the right sound? or am i screwing something up?

            DO NOT DO IT THAT WAY
            Especially with a knife, you will crack the screen and be DONE IN !!
            It may be double faced tape releasing
            go from the outside between the two plastics

              I just looked at one picture and cringed-- SERIOUSLY !!! A SCREWDRIVER !!!
              you do realize that most people looking for help have not done this as often as you have and will probably crack or scratch their screen when they slip !!

              Maybe if you wrapped it with tape first

                ok, so i got some help popping the front off. Here's what i've got on the inside and PSU side Now on the PSU side, all of them look slightly bulged, and a couple of them are obviously cracked, but do those seem to match the symptoms, since they're on the PSU side? Primarily being that it was definitely getting power, but not actually displaying an image?

                  yep it needs caps on the power board

                    The small one meaning the leaning tower of piza over there by itself?

                      I do not notice it leaning too bad
                      it is C10x (can't read the rlast number)
                      between the yellow square hipot and the aluminum heatsink on the power supply

                      I do see a leaning one on the vga dvi board-- but that boards caps look ok

                        ok I see the one you're talking about now. Trying to source them now. One radioshack only had the leaning one, so that's not a concern that it's bent over like that?

                        Edit: so far radio shack is saying they've only got 1000uf in 35 & 50 v which if i'm not mistaken will likely bring about the end of the univere if i try to use them, correct?

                          http://www.digikey.com
                          will take 2-3 days to get to you but prices and product will be better than radioshack

                          leaning one is ok since it is going perpendicular to the pins. you can right it if you like

                            Th screw drive is to show that you will lift that section up while I am taking the picture, you lift it up with your finger. I only have two hands. When you work long enough you will learn what not to do. Wooden stick from ice cream works great and you have to take your time and do not rush.
                            Caps: I use PANASONIC FM/FR/FC series. They have to be low ESR type for switching power supply.
                            I.E. Just match the dimension, voltage (higher is OK), Capacitance (a little higher 20~30% is OK)

                                Take good notes where each cap is removed from, then use the ruler to measure the Dia, and length (in mm is preferred) to match with the replacement.

                                    For the big ones, it's 1000uF, 25v and this is is the only match (actually, i tihnk there were 2, but they seemed identical to me, on the chart,the other just appears to be an out of stock bulk.

                                    The small one is 33uF, 50 v, of which digi key is giving me no matches for.

                                          Three 820-01700 32GB Logic Boards Same Issue: Won't Wake From Hibernate
                                          by ugamazing
                                          I have three identical-spec 820-01700 boards (2.6/32/512), and ALL THREE boards came to us with the same fault, from different sources: The boards don't wake from hibernation with the keyboard or lid, they ONLY wake when you press the power button. I understand this is a very minor issue, but the boards must be fixed!

                                          We will of course begin with the obvious (checking lid signals), but I couldn't help but notice these three boards were all 32GB variants. Has anyone noticed an issue relating to these 32GB boards in particular? I of course don't think it's a RAM issue, but it's bizarre...

                                          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.

                                          4 weeks ago i launched Metro Exodus Enhanced and during cinematic advertisement part ( 30 fps ), pc just shutdown.
                                          Also monitor flickered with NO SIGNAL 10 seconds after shutdown. So only monitor and pc was affected.

                                          Next i pressed only power button, rebooted again and its fine again. Happened once and i cant reproduce.

                                          Hi
                                          There's this old LG 1510S LCD Monitor that had 2 issues, one with inverter board and one with image display (mainboard maybe), the issue with the inverter was that when i turned it on it goes off after 1 or 2 secs. and the problem was with the tuner caps on inverter board, after i changed the caps monitor stays on but there's another problem that if I turn it on by the power button, no signal message does not show on the screen, but if I let it stay on and disconnect by the power cable and connect it again the no signal message will appear, and one more thing...the 12V power is 17V before...
