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 re-purposing 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
Ten 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.

回答“Visio E55-E2 Screen Black, Sound Still Plays”famicomman89 your boards look good and I cannot make out any obvious damaged component. Vizio is a bit of an odd brand since they are using a hodgepodge of parts and boards. QA is not always perfect so they have had their fair share of bad solder connection. Remove your wires and reseat them after you check their connectors. Check the solder on those. It should appear in a shiny silver. Dirty grey with cracks could be indicative of bad solder connections snd might require a reflow. Since you can see the screen with a flashlight your main board is most likely okay. The issue should be either the power board or the backlight strips themselves ( another common Vizio Achilles heel). I would measure the voltage on the power board to the backlight LED’s (set your voltmeter on something like a 300 V scale and see what you get). If the voltage fails it’s most likely your power board. If it does not, you may have either failed backlight strips or connector issues. Let us know what you find out.
回答“Fan full speed after booting and no video signal”@pfra17 try the common resets first Common Reset Procedures When a reset procedure is required for troubleshooting, follow the applicable steps: Resetting the System Management Controller (SMC) To reset power management via the SMC chip: 1. Unplug all cables from computer, including power cord. 2. Wait at least 15 seconds. The SMC reset occurs automatically once the Mac mini has been unplugged from AC power source for several seconds. 3. Plug power cord back in, making sure power button is not being pressed. 4. Reconnect keyboard and mouse to computer. 5. Press power button on back to start up computer. Resetting the SMC means you will also need to reset the date and time (using the Date & Time pane of System Preferences). Resetting the Parameter RAM (PRAM) To reset PRAM, 1. If the computer is on, turn it off. 2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in Step 4. Note: If the keyboard does not have an Option key, use the Alt...

回答“monitor turns on and off every few seconds”Kaye Andrea Ruiz tell us what happens when it turns off. Let us know if the Power LED goes out or if it is just the screen that goes dark. Shine a flashlight beam at an angle against the screen when it is dark and see if you can still make out what it should display. this is most likely a main board issue but could be the power board as well as the backlights. Hence we need more information. Another thing you can try and do is to remove the back from your monitor and take some good pictures of the boards. Post those pictures with your QUESTION so we can see what you see. 在已经存在的问题里加入图片
回答“TCL TV - Vertical lines left side after LED backlight replacement”@timmy1892 could be a T-con board/main board error as well as LCD driver board error. We would need to see what all of those look like. Check the ribbon cables that enter your LCD and originate at the LCD driver board. If you push down on those do the lines on your TV change? 在已经存在的问题里加入图片
回答“Samsung A71 water damage!”NicolausX you are not telling us what you did about the water damage not are you telling us if your computer still recognizes your phone etc.. For now I suggest that you stop continuing to try to charge, sync or otherwise use your phone. This potentially can make a bad situation worse.This may further damage your phone. The next thing to do is to clean it. The very first step I would take is to disassemble your phone. Use something like this video to help you disassemble your phone. Take a careful and close look at all components and connectors. Truly assess the damage. Look for major corrosion, evaluate the pins in the connectors etc,. Take a look at all connectors as well as cable ends. You will have to remove all the EMI shields. If you do not remove the shields, you are not cleaning the board. Once you got the gross contamination cleaned, use 90%+ isopropyl alcohol and clean your parts some more. For a proper cleaning, use this guide. It was written for an Apple iPhone 3G but it is still pertinent to...

回答“Bose speaker not charging”hariom gangwar not quite sure what you mean by this “battery reduced “ but I’ll assume you mean the battery went down and did not longer work. Since you already tried a different cable I suggest that you change the battery. IF nothing else it will provide you with a known-well starting point for further troubleshooting. Let us know which Bose speaker this is so we can try and help you further if needed.
回答“Why 32 watt bulbs will not work?”@ifixit2021 you may run into the issues where a T12 primarily run off a magnetic ballasts and T8 bulbs operate on electronic ballasts. Try another T12 and see if that works or change the ballasts to the T8 type.
回答“Why do I have these lines on my TV screen?”sandy woods could be a bad T-con board, bad main board and worst case scenario the panel. I would replace the T-con board first. Let us know what model your Samsung is so we can check on that a bit more.
