    I've got an older DSOX Agilent 100Mhz oscilloscope. I already had to fix the power supply in it... there should be a thread about it around here somewhere.

        Do my burning lil eyes see a TTL port on the back of the main board that waits for me to be mutilated? Interesting. I might have to try that!
        Something else. I did open up the back of that thing to the the 30800-001002 number printed on the main board. Well, supposedly on SJ, TCL uses the same main board number on a 55S450F? Does this work on a TCL?

          Doesn't even show your TV on SJ.

          Did you try disconnecting one ribbon at a time yet

            Pretty sure you need to match up that exact number to your tv.. so that would be the correct replacement if that is actually the correct board for the TV. Weird

              Nope. I just went down to see the main board number, but I'll get there…
              put in that 30800 number in SJ and that one came out of a 55S450F. So mine and theirs had the identical number, even so mine is a 65”.

                Yup, looks like I found another of this same board that goes to a 43 inch. It's definitely the one you need then.

                https://www.ebay.com/itm/25659833730...mis&media=COPY

                Obviously after trying to test panel or tape method maybe

                  Well by George I think that's it, I looked at those and they match both the sticker # and the board # that is right by the sticker #, I think they will work. The picture in post # 66 is your board correct?

                    Yeah, the 3800-001002 is the same for 55” and 65”. So unless the panel is short, this TV is a going again.

                      Yes. That pic is my board. I did notice the right LVDS cable being in there crooked. Anyway… I’ll figure it out, but if it is just a flash… would be even a no parts required repair!.

                        Indeed, that would be cool, I'm not sure whats up with tcl but I was looking at how to manually update with usb on these recent models and didn't see any defined instructions. I might not have looked deep enough tho.

                          A thought is, with tcl being "kinda" unpredictable, it might not be a bad idea to have a backup mainboard if the price is decent ala post # 67. I see they ship to Canada, looks like around 45 CAD shipping included. Plus tax of course, must have subconsciously forgot to mention tax, hate tax, tax tax and don't forget the tax on the tax.

                            I am not paying any more tax Dollars to our Liberals than I absolutely have to. Lately I am cheaper than @$$. Could I? Sure, no problem. Do I want to? No! Only if absolutely required.

                              I hear that, it's sick, the more people agree to tax hikes and usually just greedy renewals that they seem to want every year. I don't like to pick on the library but its the first thing that came to mind. They just rebuilt every library like mostly ground up, every library in the area and now they have another tax up for vote already. They did the same damn thing for the schools, tore m all down and rebuilt every one and I'm pretty sure some of m were only 20 years old. It just seems like a waste. I seldom use the library and haven't used a school in a long long time. Got to turn them down sometimes so we can at least eat, forcryingoutloud small exaggeration for effect but I think we're getting ripped off. Certain taxes are a necessary evil naturally, I just wish they kept strict watch on where the money goes because someone must be lining their pockets with gold.

                                Before I go to work, I went quickly downstairs and checked that out. No, it does not make any difference at all. The behaviour is exactly the same. That's all for now.

                                  There is a big difference between your Liberals and ours. Ours is far left!

                                    I'm not on the fence at all, liberals are what's messing up most of the world imo, liberals, greed and greedy liberals. Our two party system is BROKEN, this I know. How to fix it, I don't know, why are the problems so easy to see but the solutions are not, hell if I know.

                                        Be careful what you wish for here. Look at German politics. They had a 3i party coalition government between SPD, FDP and Greens aka traffic light coalition (red, yellow, green). Needless to say nothing much got done.

                                          Plan is right now to see if I can fix it with no parts required. Right now I think it is a bad or corrupted flash. Lets see what we can do with that. I can always buy a new main board. If I have to, I will, but I want to exhaust the other options first.

                                            by Verlengsnoer
                                            Hi all,

                                            at firs, i hope this is the right place to post my question.

                                            Im looking for a tool to change the bios logo.

                                            everyone knows when you turn on your laptop/pc you will see the manufacturer logo like lenovo, hp, dell...

                                            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.
                                            ...

                                            Fujitsu D757 sff desktop pc with company logo and it doesn't work to restore the factory logo with UefiModL tool. I need to restore many of these machines to the factory Fujitsu boot logo! Does anyone know a solution?

                                            Can 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.
                                            TIA

                                            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...

                                            Fujitsu Esprimo K557/24 allinone desktop, boot logo

                                            Hello 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!
