    LED Light strip failure , How to reduce service time !!

    Hi Guys , how about this for an idea, I might well try this on my TV set at home when the LED light strips eventually fail .

    If the set has a couple of LED light strips such as vestel made 32 inch sets do, now that these strips are readily available brand new for around £11 a strip ,why not put a couple of extra strips in the screen while you have it all in bits, so instead of having 2 you now have 4 and then just poke the two extra wires out the back of the screen , then next time if fails all you have to do is connect up the two extra wires and the sets going again , saving the half hour screen strip down !!!!!!!!!!

    Instant repair with no down time , essential when you have kids playing x box games all night long !

    Re: LED Light strip failure , How to reduce service time !!

    Will you do a video buddy ? I like mod projects like this but you will need to then cut hiles in the reflector and find a way to wire them in series. Or do what I have done to this strip as a test to make them more reliable, I have heatsunk the Leds with a small vga ram heatsink (using silicon plaster to mount it) I put them directly under the Led which is what gets hottest. I then wired 3 Leds in series with no resistor for the return with 12v input which is alot of stress on them and they barely get hot with them heatsinks. Then you could super glue them down to the chassis.

        Who you taking too ? If its about my idea I said that you can apply small dabs of super glue around the bottom of the heatsinks and stick them to the chassis.

            the most part at repair i do hate remove cover screw and re screw them back .. since i will do it of sure again to put the spare cable.. best way to me always to my home set not customer, i replace all LED at once i do access to strips. thought 100 pieces always less than 10 $ and strip had 56-58 led.

              Simple fix is to remove a few current sense resistors on the PSU, that'll drop the LED current down. I drop the 400mA Vestels down to 200mA. The image is dimmer, but not too badly due to logarithmic response of eye (50% less power ~= 80% as bright)

                  I think he is talking to me he seems to have some sort of problem that I can do a repair for £30 , what I have learnt in business is that the cheapest person is the one who has the most customers , so Mr flocko you might want to change your attitude because what you are doing on e bay cutting up a few old light strips and selling them is not unique or has patent pending on the idea and come Monday afternoon I could have the same item on e bay for £1.00 each, Oh and before you say these are not old light strips they are from brand new transit damaged set I have 2 pallet loads of brand new sets sitting on the floor I could remove the light strips from , just like you are doing.

                          Oh--I DO love it when Engineers argue.....

                          As to the O/P's idea--Great providing its your own set. Doubt it would be a great idea financially or for other reasons on a cust set or one for sale...

                                          Problem

                                          This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

                                          Schematic : DAOP5EMB6E0 REV:E​

                                          I have tried manually flashed the bios, also tried hp bios recovery tools to recover the bios. But no luck. Display is not coming, 3 to 4 times recovery display is coming if I tried to recover by pen drive[win+ B]. But after restarts it goes to dark screen and a light is flashing after a certain time in the display + fan speeds increasing and decreasing. I have tried almost every bios for this motherboard avaiable in the internet.
                                          Any help or guide to proceed?...

                                          High Pressure Sodium Yard light when air conditioner turns light momentarily turns of
                                          by sam_sam_sam
                                          I have had these 70 watt high pressure sodium yard lights for many years now probably at least 15 years or more and there is a protection diode that after several years starts to go bad and when it does this it has momentarily shutting down the light and then a few minutes later it starts working again

                                          This about the forth time I have fixed this one and you can tell if it the diode or not if it lights up and it only shuts down when the air conditioner turns on then it is the diode

                                          If it cycling on and off constantly then it is the bulb itself that is the issue
                                          ...
