    iiyama ProLite E2200WS

    Picked up a couple of these monitors today. They had unknown faults.

    The first one I tried came on fine but it was OSD locked. I unlocked the screen by keeping the 'enter' button pressed for a few seconds. I then set it up on my main PC to soak test it whilst I looked at the other monitor.

    I thought that maybe the person who owned it before didn't know how to unlock the menu but it seems that after a while it came on with the OSD on its own. I did a couple more resets and it seemed to come and go. Its been running for a couple of hours now and I haven't seen it come up again. I am thinking that its maybe gone as the unit had been on for a while so I will leave it off over night and have another go tomorrow.

    The second one came on for a few seconds at first then turned completely off with no standby light. When trying to turn it back on the length of time it would stay on became shorter until it would not come on at all. Not even the standby light would operate.

    I tested the only Voltage Regulator on the logic board and that was constant 1.5v as it should. The big cap was pushing out 330v and all of the caps looked fine. There were 3 x 47uf 50v caps 2 of which were only measuring about 7v. I replaced them with some from my ever increasing box of spare caps and sure enough the monitor fired up. Its now been on for a good hour or so without turning off.

    I have ordered a full set of caps for both monitors as they are both in really good condition.

    If the first monitor continues to randomly bring up the OSD then I am lucky enough to have a spare button board for it. If that doesn't cure it then i'm not sure whats going on.

    Turned it on this morning and it is behaving like the enter button is being constantly pressed.

    I will wait until the caps turn up and then swap the switch board over at the same time.

      Decided to swap the switch board out for a spare one that I had to see if that cures the problem. Just turned it back on and it seems to be working fine. Going to leave it over night and then have a look in the morning though to see if it starts up again. Fingers crossed it wont.

        Tried the monitor this morning with the replaced switch board and all is working well. The menu isn't coming on all on its own any more. I am going to leave it on all day but it looks like its cured.

          Try some contact cleaner on the faulty switch board - worked well for me when I had a TV that would turn itself off occasionally.

            Hi,

            sorry te unearth this aging thread but it does cover a specific model I'm looking at. I have a Iiyama 2200(ws) that has developed a curious problem. At first it worked fine. Then I noticed I couldn't turn the monitor on or off. It would follow the computer for on or off behaviour. It would go into sleep mode no problem and wake fine as well.

            I just unplugged it as I was redoing some basic power wiring for my office and now it refuses to turn on!

            Never any issues prior, never blacked out nothing. Just all of a sudden poof. Opened her up and visually no signs of any issues. Where to begin?

            cheers,

            The Newbie.

              Just all of a sudden poof - was that the noise it made or do you just mean it doesnt come on?
              If it is totally dead test the main white fuse near the mains connector.
              If the power led comes on then test the two yellow fuses on the other side of the board.
              Also test the mains fuse in the power cable

              I have assumed you have the same board as OP but we really need you to post good clear pictures of your board.
              Please upload pictures using attachment function when ask for help on the repair

                I had (and still have) an iiyama E2407HDSD with a similar issue, turned out to be a dodgy power on button, cracked solder joints. I also found the power cord input (IEC mains conn) to have a cracked live and earth connection though they weren't yet failed, I did those too. It's been working for 18 months now after that repair.

                  Hi,

                  Sorry for digging up this very old thread, but because the issues with my Iiyama ProLite E2200WS monitor sound very similar to Jasgriff's original post, I though this might be the best place to ask for advice.

                  Let me start by saying that I am very new to this and have little experience in attempting to repair electronics, so please bear with me.

                  Recently my trusty old Iiyama E2200WS monitor started to have some issues. After having been on for a while it would suddenly turn itself off: black screen and no power LED (neither green: powered on, nor orange: standby). Pushing the power button would switch it back on, but after a short while it would switch off again. This repeats itself with increasingly short intervals in which the monitor is on, until it will not turn on again at all. I found that disconnecting the power cable, waiting a bit, them plugging it back in and power it on would sort of reset this cycle. Another trick I used for a while was to fix the power button in the pressed down position by wedging a toothpick in next to it. This allowed me to continue using the monitor for a day or two. Things got worse though, and now it will not turn on at all, at most just blinking the green power LED at me before switching off again.

                  I have opened up the monitor to have a look at the power board and the small board that has the buttons on them. From reading on this forum and other places, I think the issues must have something to do with either the caps on the power board or the power button on the button board. However, a visual inspection of these parts doesn't seem to indicate that anything is wrong with them.
                  I have attached some pictures of both boards. I can't discover any broken connections or bulging or leaking from the caps, and the power button looks attached firmly to the board. (The power button is the one next to the LED.)

                  I am now looking to get some advice on how to proceed, before I start trying to replace any parts. Based on my description, can anyone tell me what the most likely cause of these issues is? What parts can I best try to replace first?
                  Also, does anyone know of a good place to get replacement parts? I live in the Netherlands, near Amsterdam, and I don't know any good electronic shops that sell single parts like these. In case the problem is with the power button, I though of swapping one of the other buttons (which I hardly use) for the power button, to see if that has any effect, because I wouldn't know where to start looking for a new one.

                  Looking forward to some input!

                    Need help replacing led strip on Iiyama Prolite XUB2390HS monitor
                    by mikey5791
                    Hi,
                    Got this working ips led monitor by the brand of
                    Iiyama Prolite XUB2390HS presumably a 23 inch type given to me with suspected bad led backlight. To test it, i unplugged the bad flat ribbon type connector and plugged it a good flat ribbon led connector scrapped from a HP Pavillion 27cw (led strip with 60 led). Good news is the HP led strip lights up but not fully, in between there are about 15 unlit leds.(as picture attached shows).

                    Fyi, i had not opened and removed the old bad led strip. My question is whether is it possible to cut some of the extra leds(say...

                    A Couple Quick Battery Questions...
                    by SolomonMan
                    All,
                    I have 4 laptops all the same HP Elitebook model. These are now close to 8-10 years old now but they all were high end software development machines (ie 16GB ram (32 max) and all now have been upgraded to 1TB SSD). They are used throughout my house (family).

                    I recently bought a Software Defined Radio setup (SDR) and I will use it with one of the laptops but the batteries appear to be all dead.

                    The replacements seem reasonable at the sub $30 range (some as low as $20 shipped).

                    So I am thinking of replacing them all.

                    So the question...

                    Lenovo T480s usb-c charging port replacement - Knocked off a couple of diodes.
                    by Nikolai Danylchyk
                    Hi folks. As the title says, I was doing a port replacement on a Lenovo Thinkpad T480s and in the process of post-solder cleaning, I somehow knocked off 2 or 3 diodes (i think they are diodes) near the main usb-c. I can't seem to find what kind of a diode is that. I know it's ultra tiny and just has a letter "G" on it. Would someone maybe have a proper schematic for the t480s model? I can only find the non-s one and it's quite different to the "s". Would love to figure out what component that is.
                    Thanks in advance!...
