Re: Help need LG W2254TQ firmware wanted
Thank you, I didn't realise there wasn't a separate t-con board. The main smd fuse is blown. It only says F1 so I'm not sure what size it's meant to be. What size usually goes on a t-con board?Comment

Hello to everyone ,
This is my first post here, and i would like to share with you a small story in case you can help me.
Docker Type-C Gen 2 - Model 40AS. Was given to me by a friend for free ,but with the problem that you cannot use the video output ports.
All ports work , USB , Ethernet, Type C ... but HDMI + Display Port don't work
I searched on reddit and google for problem similar to that, and a LOT of people had fixed this problem by updating the firmware. So i tried , i searched and found 1.1.13 utility and 1.1.20 utility that can help...02-10-2024, 02:07 PM -
Hi guys.
I've got a Ubiquiti US-8-150W POE switch which has issues with updating the firmware.
Turned out to be a bad EEPROM chip. It would read the firmware and work as normal, but failed to write new firmware to it.
So I took off the chip and read on EEPROM and saved it. Wrote to old chip and failed to write
Got New chip and writes good.
THE PROBLEM...
It fails to fully load the firmware, POE lights fail to work during g firmware test during load. I'm suspecting bad EEPROM Read.
Does anyone have a Good Firmware I can have?... -
I was given this set and do not have the original remote. It will turn on with the power button and display "oobe V1.1.12 firmware V0" but that's all it will do. It does not respond to the input select button or volume button. I have a remote from the cable company and programmed it for Vizio and it will turn the set on and off but that's it, no response from any other buttons. The white standby led comes on bright at first and then dims but stays on while the set is on. I pulled the back off and looked for anything obvious like loose connectors, bad solder, bad caps and didn't find... -
This is a shot in the dark, but I was just using my RT809H programmer and it got stuck in a certain state so I power cycled it. Now, the device LED just flashes quickly and does not connect to the software. I've tried to update the BIOS of it and it fails. I went so far as to remove the ROM from the programmer itself but it's some weird chip (I believe ATMEL, but I can't find any datasheet on it) so I've been unable to read the BIN from it w/ my other programmer. Chip has ATMLHC4C56BM CN written on it (I think). I'll upload an image. I have the programmer's BIN ready to program it manually. Anyone... -
