Re: Element ELEFT466 bad LED, read this before trying to fix!
Hi, I have a Element elfelt466 tv with no backlight. Con11 has 115v on the red wire but the rest of the block connectors have no voltage. Is this a sign of a bad inverter or a blown Led?Comment

Ok.. this is the story:
Have an old Samsung LED 3D TV (UE55F6475). First it started to lose light on the lower 40% of the screen now and then. Like for 10-60 mins and then it would work again. Then a bit later it just got stuck in that position. The lower 40% of the screen is dark, and it gets progressively darker the lower u go so it's obviously that LED strips where not working. I also looked for similar errors online and saw an exact copy and on that one it was faulty LED strips.
This is kinda how it looked, just that mine were at the bottom of the screen:

There is a motherboard Gigabyte H610M S2H V2 (DDR5), I can't find boardview
Help to identify the element, marking on the element - C31PH. It stands next to the USB 3.0 and it looks like it is ESD Protect chip. We need a datasheet to this element. Maybe someone has already identified such an element. Help please.

I've got this circuit that I've been playing with on a breadboard. I'm not happy with it mainly because the MOSFET gets too hot and generally controlling the temp of the heating element with the Arduino has proven to be a little more cumbersome than I would like.
What I would like to know, is what is the best way to set up a circuit like this? The heating element is just a PCB and its going to be mounted under a 3D-printed enclosure that a lizard will use to warm his belly.
This is the general setup that I have now.
This is what the... -
I was Ollie today which is a close out / surplus outlet store I do not go in there to often because you find things that you should not be tempted by but that is a another story
I saw a small space heater that used a wire type of heater element which I been looking for a while but not really hard mind you but when I saw this I grabbed it I going to go back tomorrow and buy the last one that is like the one I bought today because I need the heater element and the ceramic insulators and more of heat element wire because this one has two different wattage settings one 1300 watts ( tap... -
Hi There!
I bought a broken 32" TV today. It has sound but no image. I checked with a flashlight and it was missing backlight
Disassembled down to the led strips and found this TV has been serviced before. Not sure if it was fixed, worked again for some time, and broke again, or maybe last repair wasn't successful
Looks like on previous repair, the center LED strip was replaced with a different model, 7 leds in it instead of 8, but when checking LEDS one by one, leds on the center strip were brighter with same test voltage (multimeter in DIODE mode) so maybe the...
