Flashing Light In One Eye When I Blink

Garage Door Wont Close Lights Blink 10 Times

Hi, Wayne here from Sears PartsDirect. Todaywe're going to talk about troubleshooting a garage door opener that won't close thedoor and blinks 10 times. The blinking opener lights indicate that the safety sensors arelikely blocked or out of alignment. Defective safety sensors or faulty sensor wiring alsocause the opener lights to blink 10 times. The safety sensors use an invisible beam ofinfrared light to detect obstructions in the garage door's path. The sensors won't allowthe door to close with their infrared beam blocked. First, look for an item blockingthe door and remove it. If there's nothing blocking the safety sensors, check their alignment.You may have bumped a sensor out of position.

Each safety sensor has an indicator light.The sending sensor, which has the yellow light, transmits the infrared beam to the receivingsensor, which has a green light. The yellow sending sensor light should always be lit.But you'll only see the receiving sensor's green light when the sensors are aligned andunobstructed. Make sure that the yellow light is on and then check the green light on thereceiving sensor. If the green light is off, realign the safety sensors until the greenlight turns on then try closing the door. If one or both sensor lights won't come on,check the LED troubleshooting light on the motor unit for an error code. The controlinside the motor unit flashes the troubleshooting

LED a number of times to indicate the causeof a failure. You may see one of these error codes related to the safety sensors on a commonchaindrive garage door opener: 1 blink–Sensor wires are disconnected, 2 blinks–Sensorwires are shorted, 4 blinks–Sensor eyes are slightly misaligned. A beltdrive garagedoor opener and some newer chain drive models flash the up and down arrows to display errorcodes. Here's a list of error codes related to the sensors on these models: Up 1 blink,Down 1 blink–Sensors are not installed or wires are broken, Up 1 blink, Down 2 blinks–Wiresare shorted or reversed, Up 1 blink, Down 4 blinks–Misaligned or obstructed sensor,Up 4 blinks, Down 6 blinks–Sensors were

temporarily obstructed or misaligned. If yousee one of the first two error codes, check the wiring between your motor unit and thesensors for visible damage. You won't be able to check all the wiring if it's routed throughthe walls to the sensors. Check the wires that you can see and repair any broken ordamaged wiring. Here's a tutorial that will give you some additional information about repairingwires. A loose wiring connection could prevent the garage door opener from closing the door,causing an error code. Check the safety sensor wiring connections on the motor unit. Reconnectany loose wires. Make sure that you have the sensor wires connected to the motor unit correctly.You should see the white wires twisted together

and inserted into the white terminal on themotor unit. The white wires with black stripes go into the gray terminal. Connect the wirescorrectly if you find them reversed. If these tips didn't solve your problem, test yoursafety sensors directly at the motor unit. This test will help you determine whetheryou have defective sensors or a break in the wiring that's not visible. We'll check thesending sensor first. Remove the sending safety sensor with the yellow light from its doorrail bracket. Disconnect or cut the sensor wire about 1 foot from the end. The sensorwire has 2 strands. Separate the strands and strip 12inch of insulation from the endof each strand. Disconnect the existing safety

sensor wires from the motor unit. Connectthe short, white wire strand to the white motor unit terminal. Connect the other wirestrand to the gray terminal. Check the yellow light on the sending safety sensor. If theyellow light doesn't turn on, you've confirmed that the safety sensors are defective. Here'sa link to a tutorial that that will show you how to replace them. If the yellow light turnson, then you know that the sending sensor is okay. Now we'll add the receiving sensorto the test. Remove the receiving sensor from its door rail bracket and disconnect or cutthe sensor wire about 1 foot from the sensor end. Separate the sensor wire strands andstrip 12inch of insulation. Disconnect the

Samsung TV wont turn on blinking red light explained fix 18

I had a problem with my Flat screen TV notturning on. Instead of sending it in for repairs I decided to fix it. Using time lapse to speedthings up, I'll show you how I did it. First I disconnected and removed the TV from thewall and laid it face down on a flat carpeted floor. I then removed the rear panel screwsand lifted off the panel to get closer to accessing the boards inside. I wanted to geta closer look at the power supply board, as I suspected it was causing the problem. SoI disconnected more connectors, removed more Philips screws and then removed the metalprotective panel over the boards to gain access. Once the panel was off, I had a clear viewof the power supply board. It was the board

with the heavy power cable wires that wentto the wall outlet plug connector. Then I proceeded to carefully unplug the board. Ialso zeroed the high voltage capacitors that were present on the board. These on mine read450 volts. I did this by holding the plastic handle of the screwdriver and shorted thelegs of each capacitor together with the screwdriver blade to zero them. I then lifted the boardoff the chassis and took a closer look. I could clearly see that the tops of 2 electrolyticcapacitors were swollen. One was actually leaking. I decided to replace those, as wellas the 2 capacitors that were beside them. From my local electronics store, I purchased4 replacement capacitors. See my notes below

for details. All 4 items cost me a total of3 dollars. Using some Soder wick, a 25 watt soldering Iron, and some solder I proceededto remove and replace the 4 capacitors. After marking the bottom of the circuit board, Igently and carefully desoldered the capacitors. You can see that I clearly marked the polaritiesof the old capacitors on the circuit board. I took this information from the top of theboard by looking at the labels on the existing blown capacitors. One must always use theexact same voltage and capacity components when replacing parts on their devices. I hadno way of knowing whether the 2nd pair of capacitors were defective by visual inspection,but for the price, it was hard to go wrong

in replacing them. Once the old capacitorswere removed, I had to clean up the leftover solder residue from the board using soderwick. If this old residue was not removed, I would later have a tough time getting thenew ones in where the old ones came out. Now it's time to install the new electrolyticcapacitors. I'm careful to pay close attention to the polarity labeling of the new ones asI put them in. Careful not to get solder on any other components I progressively moveup the circuit board one connection at a time, always careful not to spend too much timein one spot. Excessive heat for extended periods on any connection can cause collateral damageto the components being soldered, the board,

or anything nearby. Once the connections wereall made, I carefully snipped off the long legs of the capacitors, and took a quick lookat the board afterwards. That's it. I reassembled the TV in the reverse order that I took itapart and fired it up. This repair I did 2 weeks ago, and as you can see, all is in order.Thanks for watching! And don't forget, I have many more tutorials for you, so please subscribe.
