Your follower , Kevork. I think you misunderstood the wire connecting here. I make a wire short between the two pins of the actual LED light not with another LEd light in the strip..
Howdy, I am an electronics tech. I service many units with LED issues, shorted and open both. I would not recommend shorting the pads on the bad LED's, this will only increase the stress on the rest of the string even if it works at all.
I have found at times even one shorted will cause the power supply to kill the power due to excess current. I have replaced LED's in many brands and have had very good luck. The main thing that gets troublesome at times is getting the LCD panel out as many are put in with glue strips. Decreasing the power level to the LED's will greatly decrease failures, and cause very little difference in video if any.
Menahem Yachad, Jerusalem, Israel. Therefore, your customer can expect the remaining LED's to fail again in a short time, leading to unsatisfaction with your work - that is a pity.
The correct fix would be to 1. Rebuild the PSU to specifications, and 2. I usually replace all the strips in the LED TV but this one, the customer did not want to spend a lot of money on it so that is why I did that. I usually explain that to the customer.
I besides, I have done that before many times and so far i did not have any complain from the customers. This is very true, I learnt that the hard way when the TV I had fixed by removing 2 burnt LED's came back after a month with the same problem! I have done this before many many times and so far I did not have any problem with this method whatsoever. I did not bother to turn the light setting in the menu and so far I did not have a complain.
I thank you though for the information presented here. God bless and have a good day. Thank you for your response. I also run into cost and mostly availability issues with the strips. I have serviced many of these units over the past several years. As I have been servicing equipment for 40 years soldering comes second nature to me. I have never replaced a strip just the individual LED's that are defective. It is tricky, but after doing so many it has become easy to do.
As for the response about the PSU, I have only had one with an issue and it was just the opposite of over driving. If you are familiar with butane hot air solder units, I'm sure you are. Just a few quick touches and it is done, of course three dabs of high temp glue to put the lens back in place. I have many out there from close to two years now still working, so I guess I must be doing fine with my repairs.
Only one call back in all that time. Thank you and God Bless as well. Interesting repair, but I agree that replacing the open white leds instead of just shorting them must be the only and correct way to repair such backlight failures.
I still do not understand how you say you solved the now open spots that still contain the now dark defect leds? I hope this answer your question. Your email address will not be published.

Menahem Yachad, Jerusalem, Israel November 2, at 5: Excellent evaluation, but not solved correctly. That is a long-lasting fix, delivering best value to the customer. And I do not make this up, but it again did cost me nothing to fix this HD dashcam recorder, so it can be used again! And this previously dead device is alive and kicking again! Others probably easily would have thrown it away!
And before I forget to mention this, the FHD p also records sound! Please give a support by clicking on the social buttons below. Your feedback on the post is welcome. Please leave it in the comments. You can also forward this website link to your friends and colleagues-thanks!
Did you reflow the 64 pin IC to see if maybe a couple of pins were not getting a good connection? No I only checked the pin connections optical Robert. And only in doubt I measure if the pin s were unconnected. But every pin was soldered perfectly. I believe that when we push a probe on a pin to check it we can get a false positive from the pressure used on the pins.
Since I already had the device opened up I would go ahead and reflow the IC pins - it can't hurt anything and it just might fix it. Forgive me, but why would you attempt to repair something that broke on the day you bought it? Why not just return it and ask for a replacement? You are right of course AdamS. Sadly my brother already had cut out some of the original box sides to keep the rest in a map.
But he probably doesn't need the box anyway because he saved the warranty card and the receipt. He will try to get his money back or a new replacement Dashcam. Sorry to disappoint you James but the brandnew Dashcam in Store really did cost 25 hard earned Euros! Super explanation and terrific photos Mr Albert! At least the repair cost nothing as you advised and it is interesting to see the inside of different devices and that's what Mr Jestine Yong's website achieves as it shares knowledge to all his readers from people such as yourself and all of the other great technicians that contribute here.

Thanks Albert, I haven't come across one tha Hey Henrique, Thanks for sharing an excellen By Jestine Yong on July 25, After some days of testing I came to the conclusion that it must have been the unknown 64 pins chip itself that previously was responsible for the S4 and capacitor components for getting hot.
Also given the fact that the FHD p dashcam battery is empty after a full charge within a day and now the chip on board is the only part that still gets a little warm, and that chip likely also controlled the OSD LCD part before. And the only reason why this FHD p dashcam got partly defect could have been the fact that my nephew had connected it to his car without using the original camera 12V to 5V adapter. According to my brother the output of that other adapter used was a bit high with being 5.
And if the camera is powered by the adapter instead of by its internal 3. Anyway, this article also again shows how to easily find those short circuits, and defects in laptops, PCs and other devices!
