Re: help me run these led strips please!!!
I sure would like to know where he will get the Brand new strip from for the BEST repair, when I used to do repair for customer, I had to explain to the customer that the parts are not brand new but used parts if the brand new parts are not available so they will understand what the chance of parts failure will be, we used to give 90 days warranty on the used parts, then they can decide if they want the unit fixed or not, if they do not want it repaired then we will just charge for the estimate for our times spent.Never stop learning

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... -
I’ve had and got a few projects using quality CAT6 and CAT7 23awg solid copper, shielded, direct burial cable. Each time I use CAT7 connectors, most of them fail making good connections to the 4 wire pairs after crimping. I tied a couple of crimping tools, thinking my crimper is bad. Also used different CAT7 RJ45 connector manufacturers. Same thing. I kinda calculate 6 connectors to make one cable!
Get this: I use CAT5 or CAT6 connectors, no problem. Very rare I have a miss crimp with those. So what gives?!

I suspect a lot of you have done a lot of repairs and end up with a lot of bad LED strips...what do you do with them?
Wonder if I should get a pile of LED chips and try to replace the bad units for the heck of it, but I don't really need the strips at the moment because I bought the strips...
Oh... and I think I got my TV working again, though not 100% I don't think, on a white screen I can see a bit of the ghost of the LED strips, must have done something wrong or the LED strips aren't quite the same as the original... -
Hi guys,
I have one very old TV.
Main problem I have with this tv is that led strips won't light.
I measured voltage levels, and inverter input is 24V.
other voltages are also ok.
What I found is that removing and connecting again connector CN1 led strips lights for shorts time (but only once). When led strips lights up then light is uniformly spread on whole panel.
First I thought that led strips are dead, but I'm quite sure that problem is not strips related.
I don't know what voltage level is at output of inverter board (samsung SSL400_3E2A) and how... -
I have a number of laptops with damaged USB-C connectors.
I wonder if I can buy a few replacement connectors from Mouser to keep, as it seems like the wafer in the middle breaks easily and oftentimes causes shorts.
I do know there are multiple connectors out there, but I'm curious to know which are most commonly used and how can I identify and purchase the correct ones.
I purchased USB mini-B connectors in the past, only to find out that the connector was flipped (Lenovo smh).
