I have a TCL 43S435 with no backlights. I contacted ShopJimmy and they said power supply. I got replacement power supply, but still doesnt work. I have confirmed that there is an image with flashlight test. I have also verified that the led strips work when I probe them with LED tester. Any ideas would be helpful. I am also geting a double blink on the status led when trying to turn it on......Nothing on the power supply looks suspect, and caps look ok. Where should I start to test......Thanks!...Today, 10:48 AM

Hello everyone,
I got a Samsung The Frame 55 inch TV for free from uncle cause it is not turning on anymore. I am in the second year of training as an electrician so I have knowledge already but I am far away from to be a pro.
The TV has Standby but ist not turning on. A Friend of mine owns a 50 inch Frame TV so I checked the One Connect Box and the One Connect Cable there. Both are good and working normally. I have opened the TV case and measured some voltages on the Board.
What I already found is that the 12.8V are not an the connector to the main board connector to the power...Today, 01:48 AM -
As mentioned above, the power goes down quickly from 394V to 374v then up and down with the same value, it usually is steady at these capacitors for everything to work flawlessly. It is very difficult to decipher what is written on this board the manufacturer has chosen white text on a bright yellow surface. Wondering what could be causing this power loop....04-16-2025, 07:05 AM

I picked this up and it had picture but no backlight. I was somewhat familiar with his TV as the LED driver fails a lot on this model. But when I tested the LED driver it had all the voltages necessary. I even had a spare one to try out just in case and that one did not solve the problem either.
I tested all the LEDs before pulling the screen apart but ended up pulling the screen apart anyways to further test them. Every one of them tests at 90 volts with the tester. They all light up. I replaced a couple as seen in the picture because I had extra and I accidentally popped the cap...Today, 06:15 PM -

I have a Gigabyte 6-77-NH50HP00-D04-5C. The device does not start. I downloaded a BIOS file from another forum and installed it. The device started with the file, but cannot find an NVMe SSD in the BIOS. A data storage device on a SATA port or USB stick is detected. In the BIOS, the ME firmware version is 0.0.0.0. TPM is also not available. Here is my original BIOS. Can anyone help me?...04-19-2025, 04:06 PM

I have bought this Zener Diode for this project what size and wattage resistor value do I need to use to get near 50 watt output
I bought this from an eBay seller but unfortunately they only had one
I bought three from Vetco Electronics these are Sylvania ECG5185A 9.1@10w A to Stud what size and watt resistor do I need to use to get near 10 watt output
I bought three of from them to also make battery packs with this output power limit in mind
I want to use this battery pack and turn it into a 9.1 output battery pack output to eliminate using 9 volt battery...Today, 05:50 AM -
Hey guys, I'm hoping someone has a spare U6-LR laying around or one that might possibly be dead for other unrelated reasons but with a potential healthy SPI dump.
Could someone please send a copy of the SPI/BIOS dump of the Ubiquiti U6-LR?
It is the Macronix MXIC MX25L12833F chip located underside of the board next to a big RF shield (presumably wireless chip/radio inside.
Here's a video on how to disassemble one, had to use a hairdryer with a few spudgers.

You can shutdown it and then if it powers on via fast start it works, but if you reboot it boot loops is here again.
