    technica led 40 e271 not storing channels

    made by UMC
    this tv would work fine on scart or hdmi ,
    but no digital channels just the first time install menu
    every time you switched on
    i tried to find how to do factory reset with no luck
    when auto tune was completed it would show how many chans found ,
    then after pressing ok or exit
    tv would return to sby and no chans stored
    i found that menu 1147 would enter s mode
    and the 6th choice on the list was
    : init fac channel ,
    so i pressed ok and ok appeared .i exited s menu and now tv comes out of sby and after 10 secs goes back to sby ,so ive made things worse
    as tv wont now stay on and cant see how to get back into s mode
    the f/w version is:v3 00,669 ,s1
    can anyone help or advise please

    You could speak with Microtech A/V Services to see if their EEPROM will do the job should the board number and screen details match.

        Isn't the code you gave above(1147) the Service Menu where Factory Reset would be one option.
        I'm not familiar with the set so other than that I'm don't know.

        On one web page it said
        "Hi on the remote control press menu 4725, select reset, thanks"

            here is the service mode,
            i managed to get back in with scart i/p

            1 ADC ADJ
            2 GENERAL SETTINGS
            3 DEBUG
            4 SW INFO
            5 INIT TV
            6 INIT FAC CHANNEL
            7 BURN MODE
            8 SOFTWARE UPDATE
            9 SILICON PARAMETERS
            10CHECKSUM

            earlier i wanted factory reset and selected 6 then ok
            that got me into deep water as tv would bootloop
            managed to get out ,with powering on with vol down and power on on tv
            so i still would like to know how to do factory reset ?
            what is debug?

            mr barton suggested eeprom replace but this is proving to be a problem
            panel number TMSD 306 69A 12023.
            if a factory reset doesnt help i want to try reprog the eeprom with CH341A
            cam anyone offer futher advice thanks

                          send an email explaining what is the problem and model number ask for the files ..if tv not quite right after update ask them for a better file .. i had to try 3 times before it was right one .
                          service@umc-uk.co.uk
                          seem to remember to reset its hold certain buttons down and power on
                          whoops i forgot that first contact was through the UMC (UK) Limited Technical Helpline then they emailed me .

                                If possible could you post Model Number, Panel Number, Mainboard Number and Tcon along with the bin file on th EEPROM thread.
                                It would be helpful for others who have the same problem.
                                Thanks

                                    Add them in a winzip file or something similar. That will work.
