Chosen Solution Hello I have a Vizio 48" Model E470I-A0 complete black screen. I did the flashlight test and able to see the picture in the back, but it flickers a little bit between lighter and darker spots. Is this the LED back lights or it’s the power supply. Thank you in advance. @randym most common error is a failure of the power to the backlight. Check to see if your TV has a separate inverter....

Chosen Solution I have a Vizio 46" HDTV. Recently, I turned the TV on and the colors are faded. The images are not disturbed, just the color. All of the colors look more pastel; maybe calling them ‘washed out’ is a better explanation. I am using HDMI cables and get the same faded colors when watching cable and DVD. Update (10/12/2015) Thanks! The model number is: VW46L FHDTV10A. I have attached a few photos to hopefully illustrate the ‘washed out’ colors which look very pastel…certainly NOT the bright HD colors....

Chosen Solution After turning on my 2 year old Vizio e550i-b2 it works normally for about 4-7 minutes but then starts to make a buzzing sound for 30-60 seconds before shutting itself off. Does anyone have this problem or know how to solve it? @jim_2077 could be caused by leaking caps or other components on the power board that get to hot and are starteing to “leak current” Remove the back of your set and take a couple of pictures of your individual boards....

Chosen Solution Basically, I broke the home button flex on my OEM iPhone 7 screen (the part that goes from the screen to the logic board). I had an iPhone 7 screen lying around, but it’s not OEM, and I want to transfer the non-broken home button flex cable from the non-OEM screen to my old broken OEM screen. How should I go about doing this? Thanks :) One question, did you tear the flex that the physical home button is attached to?...

Chosen Solution The washer is spinning off balance. How Do I adjust for that? Cause 1 Rear Drum with Bearing The rear drum has a bearing or bearings in it to keep the inner tub spinning smoothly. If the tub bearing system is defective the washer can become very noisy. On some machines bearings are sold separately from the rear drum, however we recommend replacing both the outer drum and bearing as an assembly if the manufacturer offers the components together because removing and pressing in the new bearing can be exceptionally difficult....

Chosen Solution Ok so my friend spilled chocolate milk on her MacBook Air 2013 A1466. She dried it out for days and turned it on and it works, but only when it is plugged into the charger. So now I’m helping her, I ordered a new battery on eBay thinking the old battery could be fried but when I put the new battery in it still doesn’t work. Now this is what I find interesting, when it is plugged in and powered on, the charger light is orange, NOT green....

Chosen Solution Hello there, I recently purchased this water damaged iPhone 5S. Upon receiving it, I immediately took it apart, and got as much water as I could off it, brushed the connectors, I attempted on removing the EMI shields but failed to remove it, so I didn’t proceed on. I tried to turn it on but received nothing. I checked if the screen on it was working by connecting it to a different working iPhone, and it indeed worked, I do not know about the battery, so I decided to put a working battery to see what would happen....

Chosen Solution what can cause a samsung LED UA40J5000ARMW version IJ01 not to on and their is current flowing in it @itxyungi you say there is current flowing in it. If that means that there is power going to the power board but your TV is not turning on, check the fuses on your board and make sure that you have power on those. You also need to check the power on all the other connectors....

Chosen Solution Hello, My laptop fails to response to touch input, in short, no touch at all while the display works fine. I wonder if it is the problem with the screen itself or from some part called Touch Control Board. Many thanks. If your touchscreen isn’t working or not responsive how you would expect, first thing is to try restarting your PC. If you’re still having problems, check for updates: Select Start , then select Settings ....

Chosen Solution I bought this MacBook Pro 13” early 2015 with a screen that looks like a bad TV channel with interference. Could this chip by the lvds connector be the cause? It’s damaged. I have another late 2013 a1502 with a similar chip. Is that compatible? Update (09/29/2020) this is what the screen looks like. The seller said it just stopped working. When I opened the case I noticed the damaged chip....

Chosen Solution What kind of connector is used to connect the AirPort card to the logic board? A data cable, and it has two antenna connectors. I believe the card has three antenna connectors; J1, J2, and J3.

Chosen Solution I’m attempting to do a display replacement and battery replacement on an iPad Air, and have just gotten to the step where I need to use an iOpener to remove the logic board and battery. I don’t have an iOpener. I was only able to get this far into the repair without one because the display was already falling off from poor adhesive the last time a repair was performed on the device....

Tried ti fix them by aligning them correctly and it worked for a few days but now it won’t read games again. I want to replace the game reader for it to work again correctly....

Chosen Solution where can i purchase propeller blades for the DX-2 drone I’m sure everyone who purchased a dx-2 stunt drone has the same issue. Broken blades on the first flight, and little information about how to get replacements. Fortunately I’ve found a solution. Even though the blades measure at 57.15mm, which is insanely different than every other drone, you can get away with using 55mm and/or 60mm blades. The 60mm blades are better for lift, but you may need to sand down the tips of each blade, in order to keep them from hitting the guard....

Chosen Solution I have a Gateway desktop that stopped working. The technician said that the power supply was out and that I needed to go to Windows 11. I told him I would try to replace the power supply - having put together a desktop from parts some years ago. He removed the hard drives saying that it was for their protection while I worked on the power supply. However they are unlike the hard drives I worked with before....
