However, I don’t have any panel power to speak of. Maybe 1V?

yeah, that I know... it still shows that in the picture as I keep "recycling" it. lol Ignore that ribbon, it sits straight for a while now.
lotas that plug on the bottom right is the speaker left. There is the same plug on the other side for speaker right. I'll see what I can measure at that point you circled tomorrow morn.

Weird tv, who do you get help from, amazon since it's their os or tcl? amazon has a chat feature, not sure about tcl. Whenever I use a chat feature I do my damndest to keep them talking til it's fixed, if they act like they want to give up, I say I need this fixed boost me up the ladder. Sometimes you have to try the resets several times, maybe try turn tv on for a minute then just unplug it from power, then hold power button on tv while plugging in hold button til you see screen come on then let go, go for a minute, no joy, try less maybe just a 10 count or 15 then let go, play with the times like that. I can't really see any reason why this tv won't reset. Always hated fire devices because EVERY single time you turn it on it checks for updates and forces them, no choice in the matter, that's why I only bothered with one original fire tv box and one stick, some friends would buy about every one that came out.Last edited by nomoresonys; 08-17-2024, 08:27 PM.Comment

this TV PSU always active. " r´thought it had only One Opto" because its Fire TV. I/O signal to drive the Panel depending on the one Soc and its firmware script. any damage at FW the Soc will be blind.
you have on MB the socket PW1 which i think its the key of supplying panel V. LVDS both had no sign of Panel V rail.
filter coil you thing it shorted from Photo its sitting on GND.
so let see the whole back of the set to follow Panel rail .Comment

I am not convinced the panel is dead. I think it is that main board that’s faulty.Last edited by CapLeaker; 08-18-2024, 06:31 AM.Comment

Here we go. Went back to it for a bit this morning. I do have 12Vdc panel power on some places on the board, but nothing going to the screen. See pictures attached. The LVDS data lines has no signals either. PW1 is just going to the PSU.

you still have 5V USB VCC and first power _On in tact ... firmware flashing are the answer always no HW issue at my eyes.Comment

yours Panel didn't need 12VCC... as i wrote before its ONE Soc. system design like the way on Mobile but with large screen .. I2C on this One Soc for Video / panel worked within the section of Kernel at Firmware... yours Kernel distributed much likely during update or et turned off and on again ..

These fire tvs are way too dependent on being online, what if someone just wanted to hook up an antenna and watch over the air non-compressed programs like the person in the LG thread, is it even possible without being online? I hate always having to fiddle around with something just to look at the news or whatever, I keep it simple. Adjust the tv to be dumb and use a smart streamer, from what I understand it doesn't wear out the eMMC chip as fast either.Last edited by nomoresonys; 08-18-2024, 07:13 AM.Comment

no need to be online to receive antenna or cable or sat.... but the set should be activated first with user profileComment

I didn’t get that far. I turned it on and worked, Connected cables to it including Ethernet. Then it said new firmware found and it did its thing. So I left the room for 10mins. Came back and found the TV in this state, Nobody touched it in between.Comment

i know that HP has a build in option to change the splash logo.
but i want to change the manufacturer logo to an own logo.
I try'd Change Logo 5.0, but when i make a backup of an laptop and edit the logo and flash the editted version back on the laptop the logo diddnt change.

by smartyCan anyone identify logo shown below?
The logo I showed can be found on the PCB's of laptops NP530U3B, NP530U3C, NP540U3B, NP540U3C, etc.
I assume this is a logo of one of the PCB's manufacturers, but I'm not sure.
Neither ChatGPT nor Copilot know the correct answer.

Hi, I have a few of these & they came with a custom bios boot logo, no passwords etc.
2 x were brand new unused but with custom boot logo, 1 I installed Windows/ran updates then it bricked itself. 1 wouldn't get past the custom bios boot logo.
The third I loaded windows, took a backup of the bios chip, then tried to flash several different clean bios's via programmer which all caused it to not boot. I tried to reflash the original bios both using clip & desoldering but...-

by p.puhakkaHello forum!
I have received a lot of help here, regarding bios modding. Very thankful!
Now I have a lot of Fujitsu K557 desktops, and those have custom bios logo/custom splash screen, and I need to change them to the original Fujitsu logo.
I am looking for the easiest way, because I have about 40pcs of them, and I think there is some "official" way to do this.
I have tried a lot of Fujitsu tools, which can inject the logo to the bios file, but no luck.
Any suggestions? Thanks! - Loading...
