      When I was in the service mode I may have accidently changed a setting. Now the tv will Not show a picture. Is there a away to reset to factory specs? Thanks!

        You can usually do it by connecting two pins on the EEPROM together. This will require you disassemble the TV though.

          Can you be more specific on the eeprom location, I'm assuming its on the main board? Which two pins? THANKS! Board is PE0541

            Yes, it's on the main board. If you get the TV apart take pictures of the main board. It's an 8 legged SMD chip.

                Do you have a higher resolution picture... it's difficult to make out anything.

                  Is there a particular part of the board you would a better picture of?

                      Bought a supposedly new board. Still doesn't work. Now my 24 volt bus is gone. My twelve volt bus flashes from 6 to 12 volts? There's two led's on the board. They flash with the voltage changes. Ones green ones yellow.

                        Put the old board back in. Now my 24 volt bus is back. One steady green led on the board. 12 volt bus back at p811a.

                              Sorry your pictures are not much use. Too small.

                              Please try and get them as near to but not bigger than 2mb 2000*2000
                              and a better one of the whole board please.

                              If you click on them as soon as uploaded you can tell if they are any good then you can delete and re upload as an edit.
                              Please upload pictures using attachment function when ask for help on the repair

                                        This is what I have been working from. Thanks though! A power supply schematic would be very helpful.

                                          by anlu
                                          Hello, i have an old Toshiba 32W1333DN (sorry, misspelled the headline) TV that had the standby led green/red flashing and no lightup problem, i repaired it by measure the led output as suspect led problem, i measured the LED:s one by one and found one bad led, i replaced the the led-straps and the TV works.

                                          Now i need to update the software because the new rc "RM-L890" does not work and i think maybe it could be an firmware issue?, i have struggled to find it without any success because all of the links where invalid, i contacted Toshiba but they do not support this model...

                                          Firmware for older Toshiba TV 22CV100U
                                          by DarrenHD
                                          HI all, Does anyone know if there exists an archive for older firmwares for Toshiba TV's? I've searched all over Toshiba's various websites and also on Dynabook's site (they say they deleted all old firmwares due to "server space". ) Toshiba has not replied to my request.

                                          I'm looking for Firmware 1.07 for the 19/22/26/32 C100U series as described in this link:

                                          https://support.dynabook.com/support...tentId=2865076

                                          Thanks!
