    Seiki SE50FY28 picture not displaying words properly! bad eeprom?

    I got this tv plugged it in and it powers up and checked a lot of the voltages and they all seem correct! But the screen is suppose to display no signal but it just has lines part way down the screen instead of saying no signal and the same happens when you try to change inputs it doesn't show the words just the lines that are representing the words! I'm guessing it is an eeprom problem but i'm not sure and need help figuring it out it doesn't have a separate t-con board where the cable from the mainboard plugs into the boards on the outside of the screen i checked the voltage on the fuse and i am getting 11.5v! any help is appreciated! i added photos and the picture of the screen is where is says no signal! i also checked the voltage regulators on the main board and i believe they are correct! thanks in advance!

      Re: Seiki SE50FY28 picture not displaying words properly! bad eeprom?

      here are some pictures of the control board that is attached to the lcd screen. the fuse on this board is where i was getting 11.5v. i also checked the big to-252 regulator it is a 1.2v 1a regulator markings are 912t45 0505 if i am correct thats what it is! the readings were 0 on tab and pin2 0 pin1 3.2v and pin3 1.2v so it seems to me it is putting out the proper voltage. datasheet says tab and pin 2 are ground and pin1 is vin and pin3 is vout. i don't know what else to check so if anyone can help i would appreciate it.

          That looks like a failed panel to me.

              Does the line move across the screen ?

                      yes if i hit the input button the white lines for the no signal disappear but then i have the same lines where it would say hdmi etc in the upper left hand corner where it should say hdmi. so the panel is shot then? if so i guess i'll try and sell the boards!

                          93C46 and 93C56 EEPROM
                          by SidneyCanadas
                          I tore apart my instrument cluster for my 2008 Toyota Corolla made in 2007 in Cambridge, Ontario, Canada and pcb location: IC6=EEPROM is a surface mounted device with part # of 93C46W7, some claim the EEPROM out of a Camry part # 93C56 will allow odometer to roll over 299 999 KM or miles. The data sheet for both is below:

                          https://cdn.badcaps-static.com/pdfs/...c6e42b20d3.pdf 2

                          Anyone know if the Camry one will work on my Corolla?. And which EEPROM reader/writers do you all recommend I purchase that will allow me to read the old values of the old...

                          Pioneer DEX-P99rs "No EEProm " diagnostic code.
                          by dmccul2698
                          Hello, My head unit developed strange behaviors so I ran the built-in diagnostic package which returned "No EEProm". The service manual says there is no EEProm connected. I approached Pioneer and they said to swap out the DSP board. All said and good but the DSP board is $860 USD. I am hoping someone can help me

                          1). Understand the schematic and check the connections between the EEProm and DSP
                          2). Check the functionality of the EEProm

                          I don't know if this is the unit's problem but it's a place to start.

                          I have little to no electronic experience...

                          Damaged EEPROM on TV Vizio E320-A0
                          by edgarmg15
                          Hi everyone

                          Iยดm trying to repair a TV Vizio E320-A0 that I found in the street

                          The symptoms are it doesn't respond with remote or buttons, the LED indicator is always off and also there is no image on the TV.

                          The power supply board works fine (I probed the terminals with my multimeter) but in the main board the EEPROM doesn't works correctly because the voltage on the pins doesn't match with the parameters of the datasheet.

                          So, Iยดm going to replace the EEPROM with a new one, but the problem is that my programmer (CH341a)...

                          Guide to transplant MEC1503 EC chip and EEPROM reprogamming for T14s gen 2 and X13 gen 2
                          by acedogblast
                          This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.

                          There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as...

                          Eizo CS2740 eeprom dump, search.
                          by AlexGsmMaster
                          Good day to all, I have a big problem. I can't find the eeprom dump for the Eizo CS2740 monitor. The device doesn't turn on, the indicator just lights up. It responded to connecting to the PC once. The update process started with the standard program and then disconnected from the computer. The computer doesn't detect it anymore. If anyone has an eeprom dump, please share.
