Re: Quantum Dot White LEDs Achieve Record Efficiency
Soon we may be seeing smaller SAMSUNG TVs with the QLED technology. As for now it is only in their high end TVs that the QLED technology is available. As for me, at the present time when I compared the picture quality, texture, contrast ratio, I have found the OLED by LG Electronics to be far superior, but that is just my opinion. This article is very good reading though. Thanks budm for the share.Comment

Hi there !
I'm having an issue for several weeks with my quite old K70 LUX RGB keyboard. I haven't used it for few months, and once I setup up again my desktop computer, I got several dead LEDs on that keyboard. I tried the Corsair troubleshooting thing (disabling options in iCUE, ...) but nothing changed so I conclude that for some reason some LEDs went in retirement...😅
Decision taken to change these LEDs as I have access to desoldering iron and binocular magnifier, I wrote a ticket to tech support, hopping to obtain the LEDs reference and... They refused to tell me 🙄...10-08-2024, 11:58 AM -
So I use this TV daily as a second monitor for my PC or my Playstation - at one point a few months back I tried to fix the problem - but in the process, I figured out something that works so I haven't posted this for awhile. It is an annoying trick to have to do though, so I decided to post about it to see if anyone could spot what's wrong. It baffles me because it works on it's own half the time.
When I first got this TV, I was told it wouldn't turn on, and of course I did the flashlight test, and the image was there. Also, the red LED on the front indicated that it had power (it... -
Hi all,
I have what should be a simple job but is causing me issues. There are three LEDs (yellow, green and red) on the indicator panel of a solar PWM controller and these have broken off. I need to replace them but I am unsure of the voltage drop across these. I don't want to replace with random LEDs in case they blow.
I took one of the LEDs out of circuit, put 19V across it with a 500 ohm resistor in series and there is a drop of about 13V across the LED, and this seems to increase as I increase the input voltage.
I thought I could just put a resistor... -
Hello everyone
I'm new to LED strip LED replacement.
The original LED comes with a single internal LED or chip. I only get at the moment LEDs with two internal LEDs or chips.
I understand that this is due to the tone of the light they emit.
My Doubt is:
Can I use the LED with two internal chips without problem?
Will there be much difference in the picture?
I'm going to replace all the LEDs.
Both LEDs (original and replacement) are 3V and the same size....03-04-2022, 04:03 PM -
I'm doing some basic diagnostics on this tv trying to find out if the main board, PS or leds are causing the problems. There is no T Con. When tv is turned on the Leds come on then go off. 20 sec later, they repeat the process over and over. Ok so I pulled the connector from the main board and replugged. All leds are lit and stay on although some had turned blue. I switched PS and got the same result. Switch MB and the results are same again. Also disco'd lvds from panel, same results, I just ordered a new set of leds cuz I would need them anyway. What is going on here? Any advice.
