Curved Flashes Of Light In Eye

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!

Sony TV How to troubleshoot a red or blinking light

hi Peg from Sony I'm going to talkabout the power indicator led light on your Sony tv and how you can use thislight to diagnose the state of your tv if your Sony tv is plugged in andgetting power even when it's not turned on you should see a red led light toindicate that the tv is in standby mode if you do not see a red or green lighton the tv check to make certain that the tv power cord is plugged in firmly into the back of the tv check the other end of the cord tomake sure that it is plugged into a working outlet if your tv is plugged into a power strip

make sure that the power strip itself isturned on or try plugging the tv directly into awall outlet many Bravia tvs also have apower cut off switch on one side which turns the power off completely make sure that this power switch is setto on and then turn on the tv with the supplied remote when you press the power button on yourBravia tv remote control the led should change from red togreen to show that the tv is on and working

if the power button on your tv remotedoes not work to turn the tv on try turning the tv on with the builtinpower button the builtin power button can be foundon the side bottom or top of the tv depending on the model if the tv powers on with the builtinpower button then try changing the batteries on yourremote control or move any items from in front of thetv which might block the remote signal if the power light has still not changedfrom red to green when you attempt to

power it on and the tv is connected to the internet it is possible that an update is beinginstalled to the tv via the internet connection wait for five to ten minutes and thentry turning the tv on again on some models the power led willchange to orange or yellow while the tv is installing an update if your tvs power led will notturn green but instead consistently

stays red while flashing off and on unplug the tv from an electrical outlet and disconnect any equipment connectedto it leave it off for about five minutes then before connecting any other equipment plug the power cord back in you should now be able to turn your tv on now if you are still seeing a redflashing light and the tv will not

power on we need to do a factory reset point the remote control at the front ofthe tv and hold down the up arrow button on the remote while holding down the up arrow button pressand release the power button on your tv this resets your tv to factory settings you should now be able to turn on your tv if this has not resolved your situation or you have further questions you shouldvisit us at esupport.Sony
