Hi Yahziel, it could be a thermistor issue or the USB charging board flex cable, you can search for the thermistor on the USB charging board and replace it with a new one, but first, check the proper connection between your USB charging board and flex cable. In 90% of cases, it’s a bad flex cable.
Hi @cma11en , there are a several posts with this issue. In 99% it’s capacitors fault. So disassemble your TV to the PCBAs and visually check the assembled capacitors, if there is no visible damage, you will have harder work, because the capacitors are having some electronics properties, but you will never measure the right value (in-circuit measuring), for 100% test your capacitors, you have to un-solder capacitors and measure the capacity by capacity test and rechargeable curve (also discharging curve), then compare the characteristics with the datasheet. So I’m suggesting you exchange all of the electrolyte capacitors on the power board (assuming to your power’s PCBA is without visual damage). The cost of the capacitors will be near to 5$ per all, so it’s very cheap repair… For this repair you don’t need knowledge about measuring by multimeter or by an oscilloscope, it’s beginner soldering. For more details and confirming please visit cnet forum with the same post.
Hi @pistol357 , for 99% it will be the LED Strip on the TV. Easily check this fact by removing chassis and power on your TV. If it’s a fault, remove the strip and search for the PN to order the same, if there will not be any information about part number (it have to be), you can order the alternatives from the eBay or Ali express, but choose carefully, read the specs of your led strip to order same, and I’m suggesting you order 2PCS, because the shine will be never same in non-original parts.
Hi Gary, this issue’s having a lot of potentially fixing methods. Older power management driver (1) Install an older Driver for Intel Management Engine Interface (2) Firtst try V10 then V9 (if V10 didnt work) Hardware collision (1) Something may block shut down - Especially HDD, if there is with cooperate with SSD. (only if your system is located on the SSD) - Reformat the HDD or use the different partition. BIOS bug (1) Re-Flash your BIOS (2) Wipe CMOS - Unplug your MB from the power supply, remove the CMOS battery and then plug the battery back Motherboard fault (1) Your motherboard may be defective, in this case, if it’s still under the warranty, send your MB back to the supplier and want a new one. If it’s not under the warranty, it’s time to start thinking about a new.
Hi @ginger0123 , if something is burned, you can easily check the burned component visually. For the complete diagnostics, you need to find the schema of the MB. So start by disassembling your laptop and search for the issue, let us know, what did you find…
Hi @kirstyw , when you are trying to connect to your TV via Wi-Fi, is the internet on the TV working properly? If no, is your TV connected to the router by the RJ45 (or optical link), or it’s just connected through Wi-Fi? If It’s connected by RJ45, there could be an issue with your “privacy settings”, check your router settings and find sharing information settings. In the other way, connecting a TV to the internet just via Wi-Fi is unstable, if you are using 4G Wi-Fi, try to set 5G and connect your TV again. Also, it’s suggested by the manufacturer, while is your TV connected via Wi-Fi, place your router near to the TV. If it’s still not working, try to exchange your router, I’m not sure, if it’s an issue of the TV.
