    HannSpree T280H odd problem

    HannSpree T280H The TV turns on just fine and you could be watching a show then all of a sudden the screen will start swiping through colors and none of the buttons will make it stop you need to unplug it then plug back in and all is fine again. Does not matter on what input or if the TV is warm or not. See the video for what I mean.

    I have no clue on this one.

    Re: HannSpree T280H odd problem

    I just got a Samsung 40" LCD doing something close to this, the panel would turn on slowly, screen would be scrambled (no audio) then it would shut down after a second it would come back with a different screen issue (lines/dots/ solid colors) (sometimes a god awful feedback noise through the speakers) then shut down. After a couple of times doing this it would snap back to normal.

    I pulled the back off and replaced the 2200 and 1000uf caps, that seems to help the slow initial turn on but did not fix the multiple on and off screen malfunctions. I got into the service menu and did a hard factory reset and that seem to fix it a little more so that it only did it the power on scrambled screen then off then on back to normal.

    So I went to Samsung and downloaded the 2 part firmware upgrade and it seems to have fixed the problem as it has not done it at all over the last week.

    I think someone was inside the unit before me as 2 screws were missing and they might have replaced a mainboard or something. To me it seems like it was going through some sort of panel mode/resolution check by itself and once it found the right signal it stayed on.

    I don't know anything about the HannSpree but if you can check the firmware maybe do a hard reset or upgrade might solve it, I know it worked on this model of Samsung.

      I would try but so far I can not find out how or if there is a "hard reset".

        I guess the model could also be HT09

            I have seen some off brand tvs that you can put into a test screen by pushing certain buttons, What I would do is disconect the cable going to the buttons and see if that helps, if it does the buttons are causing it to go into a test mode of some kind.
            Its easy to try.
