    HELP, Sceptre x22wg LCD, No Power !!!

    It just stopped turning on the other day (no anything when pushing the buttons), From what I do know (very little, lol), it seems to ONLY be the power... SO, I figured if I replaced the whole piece (#4) it would work again... BUT, I am ALL ears/eyes, and would LOVE to know how to "fix" it, especially because I HATE throwing things out, AND Buying new ones... I can take a couple pictures of P.S. if that would help Identify any possible problems... Let me know, and Thanks for the help...

    ALL the caps look O.K. to me, Should I replace them anyway? Do you see anything???

    Test U310. To find out how, you'll need to identify it. Post any markings on it, maybe a closeup from the side if you want help. You may need to desolder it if the markings are on the flat side. Also, check the fuse (marked F110 near the AC connector). Measure resistance, it should read close to 0. If it's significantly higher, it's blown.

      Tested U310, it shows around 10:30 on my multireader... you think that's it? Who may have one of these, I have the equipment to solder another on if I can find it .. thanks for the quick reply...

        You'll have to explain how you are testing (which probes where) and what settings you are using on the DMM. Don't forget to post the markings so it can be identified. Also, how did the testing of the fuse go?

            For a number of reasons, both health and personal, I will no longer be active on this board. Any PMs asking for assistance will be ignored.

            Never be afraid to try something new. Remember, amateurs built the ark. Professionals built the Titanic.

              RC,

              You got it... Just trying to get more eyes on the PSU Mobo Pictures, to see if anyone see's anything I am missing.... Sorry, I will stick to one thread....

                  What's happening is that you have been given advice but don't seem to want to follow it. A couple of folks have asked you to try things but have been ignored. After awhile, people will assume you aren't willing to listen for one reason or another and will give up trying to help.

                    W,

                    I attached a pic of the DMM I am using, and I am using it AS SHOWN IN THE PICTURE. I turned U310 to the sides, and found it to be in perfect condition other then the small imperfection (melting) on the top... I also found that it has 3 prongs going into the motherboard, so I tested the following combination's from the underside of the PSU Mobo, and have found the following:

                    2 Outside Prongs show -8, or -9
                    The Middle and Right Prongs show -10
                    The Middle and Left Prongs show -2

                    I Also recorded the text from U310, and it reads the following:

                    KIA
                    431A
                    620

                    Not really sure what it all means, as I am pretty new to this... I also tested the Caps (all 6 of them), and got similar results...

                    Big Black Cap in the middle is reading 165, OR -165 (depending on Red/Black positioning, as they ALL were -/+)

                    Little Brown Cap reads 12, OR -12
                    Big Green in the Middle reads 12, OR -12
                    Big Green on the side reads 12, OR -12
                    ALL the small black ones EXCEPT ONE read 4-5, OR -4 -5
                    The one in the corner (closest to the Screw hole reads 12, OR -12

                    Does this tell anything??? I have read a few of the different posts for this Monitor/Caps, but have yet to run across anything listing the numbers... Its probably there lol, but I haven't found it yet... Thanks as always...

                          Please, lay off the capital letters -- you've been asked before. First thing I would suggest is to read your multimeter manual (page 2). You have your probes in the wrong locations. This may or may not change your readings.

                          As for U310, the datasheet says that Vref should be right around 2.5V, so set your multimeter to the 20V range (also on page 2 of your manual) and re-measure.

                            When providing measurements, at least include the units so we at least know which mode you are testing in... are you still set to 500VDC range? To test the fuse, switch to resistance measurements (section 4.5 of your manual). Use the 200 Ohm range and check for continuity. Very low (near 0) means a good fuse.

                              I have a suggestion.

                              Spend a couple of hours learning how to use your DMM properly first. The fact that you have the probes plugged into the wrong jacks shows you require some basic training first.

                              The readings you are providing are incomphrehensible and you can do serious damage to the multimeter or yourself when probing the high voltage side.

                              Spend some time on youtube and search for multimeter tutorial. Then measure some things around the house like AA batteries, bare wire, etc and your LCD with POWER OFF.

                              After, and only after, then come back and follow the suggestions made by members.

                              If you have access to the public library, go borrow electronics for dummies (which is how I started back 6 months ago) and read through the section on how to use the multimeter.

                                I re-tested F110, with the settings change, and it reads 0.9 Ohm, so I think it is o.k. (I am guessing that is low, as I am unsure the scale)... re-checking into U310 and reading the data sheet (takes many times to read through, as I keep re-reading lol), and will re-check soon... Thanks again...

                                  Going to check out youtube, and continue to read the DMM guides... Def hit some sparks while testing the board. lol... Been on Several forums (from building my eyefinity setup, to Rooting my Evo), but none have been this snooty... Its sad when help comes at this price, guess I will probably scrap the whole thing and buy a new....

                                  Thanks again...

                                    No one is being "snooty". I made the suggestions for your own SAFETY.

                                    The fact that you are seeing sparks when you using the DMM and have the connectors in the wrong probes are DANGEROUS TO YOU! 120V mains voltage rectified to 165V can SERIOUSLY CAN YOU HARM or KILL YOU. Or BURN DOWN YOUR HOUSE.

                                    Additionally, the sparks may have caused more damage to your board. So what might have been a simple fix is now more challenging because of potentially shorted components due to the sparks.

                                      And with that, I will join the others on the sidelines. If I may offer a bit of advice: if you are unsure about something, then ask. No one around here assumes anything, especially level of knowledge and/or experience. Remember that messing around with this stuff can cause serious harm (or kill you). I honestly don't see what's so condescending or snooty about asking to provide basic information, but you've made up your mind that we are somehow mistreating you. Best of luck to you, I hope you are able to fix your monitor.

                                        No one is making snide comments. We are just confused when there are no units.

                                        Once you get more experience in using your multimeter, come back and re-read your postings with the measurements. When there are no units, we don't know if you are measuring ohms, voltage (AC or DC), amps (AC or DC), etc.

                                        Imagine walking into a computer store and asking for a 50 hard drive. Is that 50MB, 50GB, qty=50, price=$50? SATA or PATA? Internal or External? 2.5 inch or 3.5 inch?
