So, who am I and why am I here? I consider myself just a regular Joe. I am old enough to know better but still believe in trying to save the world and humanity. One device at a time. I love to mentor and to help others, I am into repurposing and trying to repair anything.
I come from a time and a place where there was never enough money to just replace things or to just go and buy new stuff. Fixing things was not a passion but a necessity. 50 years of fixing, building and yes, breaking things as well, has taught me a lot. During my lifetime I've learned that the only thing that truly matters is how we get along with others; to never prematurely judge people. I do judge people by their actions and not by some preconceived notion. If you are being kind and compassionate toward our environment (people, planet, animal, etc.) you are okay in my book.
I have learned a lot and continue to study and learn new things daily. This enables me to provide some answer on this forum. It enables me to help someone that needs it and it helps to keep things going. All too often we discard stuff just because it is broken and we do not know how to fix it. This puts an incredible strain on our environment and it makes others rich. We all should support organizations like https://repair.org/stand-up/ to fight for our right to repair. It’ll keep our hard earned money in our pockets instead of further feeding the Profit-before-People (Planet) machinery.
“We all want to help one another. Human beings are like that. We want to live by each other's happiness, not by each other's misery. We don't want to hate and despise one another. In this world there is room for everyone, and the good earth is rich and can provide for everyone. “ (Charlie Chaplin in “The Great Dictator”) Totally awesome expression thereof shown here
Nine years on iFixit is a long time. After some debates with family and friends, I’ve made the decision to take a step back and to slow it down a bit but I will continue to support the efforts by everyone put forward on here.

"iMac won't turn on after soldering the display connector back."에 답변@hru1207 remove the connector once more. You have too many solder bridges and looks like poor connections on some contacts. Clean the pads with flux and solder-braid. After that try to solder the connector with a technique called drag soldering to attach a new connector. Right now every attempt to start your computer runs a chance of shortening power-rails and creating more damage
"How can I find the shorted parts on my motherboard?"에 답변@yocracra we need still pictures of the components as well as the area on the logic board. what you have here is a whole bunch of damage related to it. for now you want to clean your board. So first take some pictures, leave the corrosion since that will help us identify the components etc. After that clean the board with some high grade (90%+)isopropyl alcohol and a soft toothbrush. Gently brush the board clean, no scrubbing. Yes, it is okay to submerge it in. Post some pictures of the after. From what I can see your board is a 820-4924-A and yes we will know what parts those are but need to make sure. That is why we need those pictures.
"Vizio P75-F1 TV shows logo then goes black. Repair help?"에 답변@hybrid_divide this is an interesting failure. One thing to consider is that just because the backlight comes on does not mean the panel is ok. Since you now changed all the boards the error could be originating from a failed LCD driver board. After all it is those boards that actually draws the pictures after having received the instructions and directions from the main and t-con board. Check those boards and consider posting some pictures of those boards with your question
"Can I upgrade my panel to 120 hz?"에 답변SUNIRBAN SARKAR it will not be an issue with the computer but you need to investigate the panel. You will need to get the datasheets for both panels. You need the labels from the back of those panels so you know the exact manufacturer and model and version number for the panels. Then you need to compare the electrical properties to see if the panels are “wired” identical or else they will not fit. If the are identical then you need to check your display drivers to see if your computer supports those. Not an easy task but start with the data for the panels.
"Can I put a 2 Wheel Dr., Toyota motor and a four-wheel-drive Toyota tr"에 답변Oscar Small absolutely can you do that. Year for year they are identical.
"Cant see gpu in device manager and fans run at full speed."에 답변lockeofnarshe this “before this my date kept resetting to 2009 “ is a BIOS/CMOS issues. Commonly caused by a bad CMOS battery that but may be specific to your motherboard. There could also just be a capacitor that holds the power for the BIOS settings. Check those settings as well and see what it tell you about your GPU (not just the OS) After that try to reinstall the drivers etc.
"What is killing my tcon board?!?"에 답변@jostewcrew post some pictures of what your screen displays. Not convinced that this is a true T-con error. Check your LVDS cables and the cables on the LCD driver board. “driver boards im thinking are good,as the backlight is lit and it is not connected to the tcon“ the driver boards are directly connected to the t-con board via ribbon cables unless I am missing something here. The main board is the one that could in theory be the culprit.
"Why is my laptop shutting off randomly while doing normal work?"에 답변@fahadbaba intermittent shutdowns are one of the hardest issues to troubleshoot. Commonly it is issues like overheating. If it happens more often and happens during times when the processor is working hard (like watching videos’, playing games etc.) this is more likely the issue. If so, you want to make sure that the air vent are all clear and clean. After that you can always check the fan and think about replacing the thermal paste on your heatsink. Also check your settings and drivers of the OS just to make sure there are no conflicts.
"Can I put superglue in a crack?"에 답변Melbury, most likely not. We would need to see the damage so post some good pictures with your QUESTION. Superglue is really not great for filling gaps and has only limited tensile strength. If anything you should consider different adhesives. Again, when we see the damage we might have a better idea.

"Red Ring of Death"에 답변Sean 29 this sounds like something went wrong with your power supply. Possibly something that shorted out with the “sprayed air in the power supply “ Time to open up the power supply and take a look at it. Remember so that there are a few of them out there and we would need to know more about the power supply. Check on here about a description on how to tear it down. Xbox 360 Power Supply Teardown Once you have it apart you can post some good pictures with your question showing the innards of the poweradapter so that we cna se what you see.
