Hello,
someone brought this telefunken branded Vestel tv to me because it wouldn't turn on anymore, I updated it's software and the tv booted, perfect, BUT it can't retain the channels and settings in memory.
When I turn it on I'm prompted to do a first time setup, I do it (or don't and perform a manual channel scan on only 1 mux), and when I shut it down from the remote the tv's led blinks for a lot of time and then it stops, when I turn the tv on I'm prompted to do the setup again; if I turn the tv on while it is turning off (blinking) the channels and setting are still there; if I unplug the tv the memory is lost.
Thinking of defective 25q ics I replaced both U10 and U12 copying the software from the original ICs, same issue.
I have a doubt on the 25q16 ic, AFAIK it should contain the panel infos (I haven't found a downloadable dump for that panel yet), I had to reprogram that IC several times because it would fail (ic content and dump mismatch).
Where are all the setting and channels stored? Has someone of you faced this issue before?
