    Re: LG 32LX1D will not turn on

    Thanks again Momaka, I think there is only one that Budm outlined in post #20...

    While googling this issue there are quite a few posts and videos but having all the info in one place really helps. Folks don't alway update the outcome which really is ashame for others. Badcaps has been very helpful and I appreciate your help and guidance. I'll be sure to update my results.
    tom66 and mdPhoenix - thanks for access to the manual. Based on the image wonderfully annotated by Budm, my board shows that capacitor labeled as "c126" - physically it is 47uf 50v but the manual lists that part as this: 0.1UF 50V 10% X7R 2012 R/TP - not sure what the story is there but I am replacing with the same thing I'm taking out. Fingers crossed...turning the soldering iron on now.. here goes!

      Well, unfortunately, replacing that cap did not solve the problem. I guess I'll be looking at getting a new dmm and trying the voltage tests that were outlined above. Not sure if it's going to help or I should just go and get a new one :-(. Any recomendations for a better replacement than LG?

        I would give a try and may you bring it back to life and it would not end up in a land fill

        Just take your time and if you do not understand some thing or do not know what to next then ask questions and some one will help you

          OH MY GOD! I can't tell you how much I miss my good old LG right now! I bit the bullet and went and got a Samsung 32UE5300 and I can't put into words how inferior the image is! The privacy disclaimer is great - They will "sync" and recommend for you but you can't seem to add anything without going thru them? I guess it just makes it easier for them to separate you from your money and collect data for the NSA's tracking activities. "Smart-TV", right! I was so much better using my laptop and home stereo hooked up for surround sound, DVD's, Photos, any web surfing, games or Netflix! Yeah sure it's nice to have integrated into the remote but I'D rather be the one in control of my content thank you. The image is so washed out it is incredible they sell so many of these. I've been happily getting over the air tv for the last 10 years on my LG with an awesome image and haven't spent a DIME for cable. Same antenna I was using on the LG gets about 2/3 of the channels on this thing! Lucky for me my homes location has no obstructions and normally gets great reception, now if I could just get a good tv!.

          I see someone was nice enough to respond with some more ideas. THANK YOU but for the moment I'm going to take a break and then watch the ball drop. This is going back in the box in the morning. Sorry for the venting... Thanks everyone and Happy New Year!!!!!

            Sorry to hear that.

            Yes, get a DMM and check the stand-by voltage. Cheap new DMMs can be found for as low as $5 (their quality isn't that good, though). If you plan on doing more repairs (either as a hobby or professionally), I would recommend you get something used on ebay for a little more. Very decent used meters can be found for $20 shipped quite often.

            Also, maybe provide a picture of your power board (if you can), just to make sure we didn't miss something.

            I feel your pain.
            My parents have a Samsung "smart" LED HDTV as well. Not that bad, overall, but I absolutely hate that SmartHUB sync/update feature. All it does is it constantly wants to update, and then only adds useless features to the TV. Me thinks it won't be too long before Samsung "accidentally" bricks the TV with those updates (meanwhile collecting who knows how much personal data... ooops I meant just harmlessly "sync-ing" ).
            But at the same time, I like to have the TV connected to my home network since I can use Serviio to stream movies from my computer to the TV.

            Oh yeah, don't you just love the sound from the TV's built-in speakers?
            My grandmother says it sounds like a tin can . (and I don't think she's wrong on that).

                    OK, IC103, T102 are for the stby power supply. Check the DC voltage between chassis ground and the Cathode of the D301 to see if it has any output at all.

                        OK, remove power and heat up C126 with hair dryer for about 2 minutes then apply the power to see if the power supply will start up.

                          No change in the reading.
                          The positive side of C126 reads -43.6v respect to neutral ground. The voltage across the capacitor C126 is 13.6v

                            When you work on the primary side, the chassis is not the ref ground point, you must use the negative leg of the main filter cap (450V) as the Ground ref.
                            OK, the 13.6VDC may not be enough to tun the SMPS IC. You can disconnect the cables from the power supply that go to the main board and see if the STBY voltage will come on just in case the main board is loading down the STBY voltage.
                            We also need to P/N of that STBY SMPS IC get the spec and pin out of the IC.
                            Since you are working in the PRIMARY (Deadly side), do not touch anything with your hands or body, to be safe, you should plug this TV into GFCI outlet at least.

                                    Those are numbers as printed on top of the IC103? That does not look right at all. That is the power supply number, NOT the P/N of the IC.

                                        Can we see close up of that IC so I can see what is printed on top? That number is not right either, you can google it to see.

                                            Hello, i have some issues with my laptop Lenovo Y700-17ISK (motherboard BY511 NM-A541), it started when i turn on the laptop, but the lcd wont turn on, i then connected it via hdmi to tv and screen was ok. So i thought maybe lcd stripe is faulty, i removed the bottom cover, disconnected main battery, reset the cmos by disconnecting battery for 1 min, then slighty move the lcd stripe. Conncted power supply and tuned on my laptop, the lcd turn on, it started to load os, then it turn off, after a second it turn on, then after like 3 seconds turn off again, and so on. Removed power supply, waited...

                                            Removing electrical noise introduced by fan
                                            by tony359
                                            Hi all,

                                            I am working on a sound processor, it tends to overheat so I fitted a fan inside. The fan is connected to the +15V of the PSU via a DC-DC converter based on the LM2596 to reduce the voltage to around 10.5V.

                                            Unfortunately the analogue circuitry is picking up the noise from the fan in two ways:
                                            1. The fan is close to the analogue section, the motor itself gets into the outputs so I'll have to move it somewhere else
                                            2. Even with the fan running outside of the case, there is still some noise which is clearly going back to the processor via power line....

                                            To all the members here...

                                            Let me tell you a little bit about what happened to my laptop (MSI GF63 THIN 11UCX model: MS-16R6) that “maybe” you know how to solve this problem.

                                            So before this problem happened, my laptop was running smoothly. When I wanted to restart my laptop, it looked fine at first. But after I waited for this restart process to take a long time, until finally I panicked (because the restart process did not finish plus the laptop screen only showed a black screen), I immediately pressed and held the power button to force the laptop to turn off. But...

                                            Onkyo TX-SR805 noise in one channel
                                            by MegaZAC
                                            Surprisingly enough, this receiver doesn't have the DSP chip issue. The HDMI board does not get hot, and sound over HDMI works fine.

                                            Regardless of the input, the right channel has noise that is clearly noticeable even on average volume level. The only cases when there's no noise is when VCR input is selected (some tracks on the board are damaged, maybe that's why), or if HDMI input is selected but nothing plugged into it. In all other cases, even when no input is connected I still have the noise.

                                            There's some logic behind it. As soon as I select an input I get only left...

                                            Acer Aspire 4520 won't turn on after reboot
                                            by robante15
                                            Hello, I have an Acer Aspire 4520 from a couple of decades ago and I want to repair it solely for nostalgia.

                                            It happens that when I turn it on after having been disconnected for a long time, it turns on without problems, it tells me that the BIOS has been reset and that it will load the factory settings, if I tell it to continue, the computer turns on and everything works fine.

                                            The moment I turn it off and want to turn it back on a second time, or restart it and try to start it again, it no longer gives an image, and it no longer responds.

                                            If I remove the...
