    Nintendo DS Lite

    My granddaughter's DS game stopped working on the lower screen. It has a back light, and you can hear some sound, but no video. Got it apart and found a cap that looks bad. It is next to the data ribbon going to the lower screen. There's corrosion on the cap and the connection. I can't tell what this cap is other than C14. I can't find a diagram or parts list. I've not worked with anything this small. It appears to be a surface mount and half the size of a match head. Thanks for any help identifying this little devil.
    The second pic is the backside of the board, it's a pot, I found something on it in an older thread.

    Just my 2cents but I would try a new screen before the capacitor. Did you also try reseating the connector?

      No, I haven't tried to reseat cable yet. If I can't get this part identifyed, I will. It's not worth a new screen probably. Kids are pretty rough on these things. Found one on e-bay for $50, screen are $35.

        Re: Nintendo DS Lite

        Parts for the DS Lite are a lot cheaper on Dealextreme from Hong Kong:

        NDS Lite lower screen - $7.40 USD: http://www.dealextreme.com/p/tft-lcd...er-screen-3175
        NDS touch screen module - $2.40 USD: http://www.dealextreme.com/p/touch-s...-nds-lite-3245

        Dealextreme has free shipping through Hongkong Post Airmail (or $1.70 for tracked airmail), however they can take 1-2 weeks to process and package your order before sending it off. Hongkong Post is very slow at sending items out of Hong Kong as well, so it might take around a month to get your order.

        I purchased the NDS Lite touch screen module before from Dealextreme to replace a scratched up one on a Nintendo DS Lite I was preparing to sell on Kijiji about two years ago, and it worked perfectly. If I remember correctly, you have to carefully peel the black plastic border from around the old module however without damaging it, and stick it on the new one before installing.

          Re: Nintendo DS Lite

          Thanks for that info. Any idea how I can identify this cap? I don't think replacing the screen will do any good if I've got other problems.

            DO you have a meter that reads capacitance?

              No I don't. But this one looks fried and shot, could I get a reading from it? I've looked the board over, and I don't see another C14.

                C14 is a multi-layer ceramic capacitor. These ceramic caps normally short out if they are bad. Measure the resistance across it with a multimeter. If it doesn't read less than 30 Ohms, it's probably fine. If it does read less, remove it and check it again out of circuit.

                If it is bad, normally I just find a junk board and pull one off that's the same size. So far, I haven't had a case where this doesn't work.

                Be careful with those ribbon cables and connectors - they are very easy to break! After opening a few of these DSs, I find them not worth my time to repair now.

                  Thanks MONAKA, I'm going to clean this thing up now and do some checking. You're right, if too much is wrong, they are not worth the time, but I'm trying to learn. I used to be green, after months of reading and building test circuits, now I'm 'not so green'. A small step up a very tall latter. I love reading this forum, you guys are the best. I'll get back.

                    Update
                    I removed connector and cleaned everything up (cap C14 doesn't look so blown up now) put it back together & same results, no lower screen display. I probed around on that cap and got no readings, there are a couple of other tiny caps on that board, I got some readings from them. So now, I'll find a lookalike on an old board and try to replace it. This will be like tyring to solder under a flea's wing.

                      Well, if its for a learning experience, then it is worth trying to fix it. Now I see that you actually mentioned this in post 1.

                      I doubt the problem is with any of the ceramic caps. The whole area around the connector looks like it has some corrosion/water damage to it. But perhaps, that's just how the picture came out.
                      ...
                      Can you post a full picture of the board? There might be some fuses. I know the game card slot has quite a few of them.

                      Did you really remove the connector (as in desolder it) or did you just remove the ribbon cable from it? Also, how did you clean it and what did you use for the cleaning?
                      I would suggest cleanning the connector with 90% (or higher) alcohol. If you can, gently try cleaning the pins inside it as well. Like I mentioned earlier - BE VERY CAREFUL! Those connectors and ribbon cables are extremely fragile.

                      And for the sake of peace, do not take appart the upper screen. The connector for the upper screen runs in one of the hinges. It's made to rip if you excert even a tiny ammount of force on it. Very bad design IMO.

                        Re: Nintendo DS Lite

                        Yea, this is a learning experence. I learned this cap is too mirco sized to mess with. I took one off an old MB that was close to the size of that one. When I removed the one from the DS, that thing looked the size of a grain of sand, OOPS.
                        I did get the cap replaced, finally, but that wasn't the problem. After i got it off and looked at it under a 60x scope, it was clean. Gave me a bad feeling.
                        So, this one is bagged for future parts ( the kids have 5 of them in service )
                        Thank You for your time.

                          If you plan to go on in electronics, either as a hobby or professionally, I suggest investing in a decent 'scope. With one you could determine if the signals are getting through to the screen or not.

                              by Ryan.man
                              Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

                              My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

                              This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

                              Hi,

                              I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on...

                              Hello everyone, I’ve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
                              I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same...

                              I'm currently trying to diagnose and fix my Vizio TV (Model M50-C1). I've tried a number of different basic solutions, but I'm trying to determine if my issue is currently a failing panel, T-Con board, or main board (or something else entirely) and whether or not it is worth my time to fix it. Details of the issue and what I've tried are below as well as why I think it is either a bad panel, T-Con board, or main board.

                              The Issue: The TV will be on and working fine but after the TV is on for ~5-10 minutes the screen will freeze (with sound continuing) until the TV reboots itself. While...

                              i have an ipad pro 9.7" (1st gen) A1674 where i replaced the screen, but never attached the screen to the frame/chassis (glued down) due to the ipad being previously dropped so the new screen would never fit in the frame properly. so i need flex/bend the chassis to eventually fix the new screen in properly. so i temporarily just applied blue tape around the edges of the screen to keep it in place. when watching videos with the ipad the screen started flicker, so i though maybe the new quasi cheap amz screen i purchased was going out. so i disconnected then reconnected with power still on,...
