    Light that has a bug zapper in bottom section of light fixture the LED light module took a crap but the zapper still works
    by sam_sam_sam
    So I got the bright idea to remove the LED light module from the fixture and put it on top of another enclosure and keep using the zapper

    The removal of light module was a successful and now I just have to cut a hole in the enclosure and put a power cord that has an on and off switch on it

    You are lucky to get about two years of service out of one before the LED module starts flicking and just stops working because it is mounted on an aluminum plate and these are hard to solder on it and it is not worth messing around with them and especially this one because it has line...

    Lift Master Garage Door wall switch display / motion sensor controller display disappeared no back light

    This happened last Saturday and today I finally had time this morning before I went to work to replace two non brand capacitors

    I will let you be the judge weather or not these are bad or not according to the blue ESR meter that I am using

    I am comparing them to a brand new one that I installed

    The display came back on and the programming was not lost which I was surprised by I would have thought that when the display went blank that so did the memory as well

    iPod nano G3 - alternative soldering point for the white battery wire
    by Norrecito
    Hi,

    A friend of mine gave me an iPod nano G3 to see if I can fix it for him.

    The device had a faulty battery and he tried to replace it but failed. In the process he managed to pull off the pads that corresponds to the white battery wire (marked with a red circle in the images)....from both sides of the PCB. Fortunetely he didn't damage anything else.
    This is usually an easy fix HOWEVER, on the PCB, I see no traces coming from the VIA and after searching the internet, I've found no schematics nor boardview for this device. With the pads gone from both sides I seem...

    Intermittent display on Sherwood Newcastle R-965 Receiver
    by BigPete
    Hi all,

    I'm working on a Sherwood R-965 at the moment. It came in with relays clicking constantly and also going into protect mode.
    I've re-soldered a lot of dry joints and replaced quite a few capacitors and now it works, but I still have one problem I haven't solved and would like some opinions.
    The vacuum display is quite intermittent. Sometimes it won't turn on, sometimes it will turn on but the characters, numbers and letters are frozen on, regardless of which buttons are pushed. And sometimes it works flawlessly. If the display doesn't turn on initially, restarting...

    Hello everyone, next I have the following problem with the Sumsour 8586D 110v dual station I bought it a year ago and it worked wonderfully, now it presents the H-E error on the soldering iron side, the hot air side works correctly..... I disassembled the soldering iron head because the manual tells me that this error is due to ceramic resistance problems, in effect, I measured it and it is open, I bought a new one that is working verified in a soldering iron and nothing.... The same error continues, I proceeded to open the station and check visually, I found a totally damaged 1R00 surface mount...

    Hey guys! It has been awhile since I've been on here. I hope everyone is doing well. I just picked up this Sharp lc-65ub30u. It plays but the screen is flashing on and off. Other than that i seems to be a great tv. Any ideas what the problem might be? I haven't pulled the back off yet. I thought I would get some opinions first. Thanks in advance for any help you can offer.

    HP 250 G7 - Battery Issue (Lid behaviour)
    by Federause
    Hi everyone,
    I have an HP 250 G7 for assistance. I've changed the battery (the old was dead) with a not-original.
    It has a particular behaviour that I've never seen:
    With the lid open, the voltage is present on the relative pins. Upon a time I close the lid, after 5-10 sec. the voltage drops down to 0. If I re-open the lid, the battery keeps stuck in this situation. I have to connect the power supply to "resurrect" the battery. In this way, I can power on the laptop without any problem and also use it without the power cord. If i shutdown the laptop, keeps it with the...

    Need Foto backside MSI ms-7e12 Ver:1.1
    by ITFan
    [B]Hello dear forum participants.[/B]

    I have received a motherboard from a friend with the following problem, which I would like to solve.
    It is a MSI ms-7e12 mag tomahawk wifi VER: 1.1.
    On the back upper right corner near the exit panel a small chip has been hit (bent and some pads torn off)
    and I suspect a 3 pin sot-23 chip (possibly mosfet) nearby might have been hit as well.
    Would need a photo of the back of this area but from revision 1.1 as the 1.0 was slightly different from what I saw in videos on yt.
    But pictures say more than a thousand words.

    Samsung UE75TU6905 reboot loop
    by brkie
    I have a Samsung UE75TU6905 from 2021, with a maximum of 10 hours of usage as it has been used as a presentation TV in the office. It started rebooting, the picture disappears, the sound continues for 2-3 seconds, and then it restarts (Samsung logo with Tizen OS), after which it returns to the previous activity. I tried disconnecting HDMI, antenna, WiFi, and using different power outlets, and it seemed to improve (or so I thought). Before, it happened occasionally, but now it happens all the time, so the TV stays on for a maximum of 30 seconds.

    I read on Samsung's website (reviews)...
