    Belinea 102035W - doesn't display properly

    Hi, I got dead Belinea 102035W display, with no backlight.
    1. I replaced BD9883F chip and backlight started to work.
    But, on the display are strange strips, I'm afraid that maybe EEPROM is bad or something.
    All caps look good, but I didn't test them.

    Here are some photos of totally black display without backligt (off) and some random stuff when I try to turn it on. Also photo of SOP8 EEPROM 24xx chip - maybe someone have EEPROM dump?

    What could be wrong? Any ideas?

      What do You mean? LCD isn't cracked or dropped. Or do You mean broken LCD processing PCB? If PCB, then - Yes I know that, it is broken. But what are guesses?
      Trying to measure caps, or my hypothesis is bad EEPROM or some caps maybe.

      I found that photos on forum:

          Tab bonds? Sorry but my English isn't very good. Can You explain in few simple words what is that? I should understand what it is in my language
          And maybe how to fix it.
          Thanks!

          Ok I Got it. Ripped cable inside the LCD itself

            Its the film that connects from the circuit board to the liquid display panel is starting to separate.

                Ok, if not bonds inside LCD - then what could be bad on LCD pannel? EEPROM 24xx? Caps? Something else?

                  there is nothing much you can do to actually fix this, besides replacing the panel.

                    Re: Belinea 102035W - doesn't display properly

                    You mean panel is LCD front panel (display)? or panel = PCB? In my language panel can mean LCD itself or PCB so that confuses me :P

                    So You think that bonds are ripped? Not EEPROM / PCB inside broken?
                    I think that guy who opened whole construction could rip something off

                      The panel (screen) is no good Ekran nie jest dobre
                      You can't rip anything of without taking the screen apart

                          Ok I got it. Sorry about that whole confusion.
                          I ment that I think, that during opening that monitor, guy in the shop could destroy LCD because he wasn't carefull enough

                            Depends what he did to the monitor. If he had the LCD display out, or the LCD apart on top of being taken out, then well... very certainly everything is possible.

                              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:

                              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)...

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.

                              Hi, I have a ThinkPad E15 G4 I am working on for fun, the PD chip is not talking to the charger, it's stuck at 5v, I have replaced the PD chip three times now (new chips) and always the same result, I have checked for shorts, correct voltages on the PD IC etc - 5v 3v, and the 1.6v on the cc lines, even replaced the USB C port protector IC and the charging port,

                              The PD IC has a EEPROM connected directly, it's the one in the image attached, I assume the PD chip will not start without some initial commands stored in the EEPROM, the PD IC never shows in device manager, i backed up the
