Hi! I have a Samsung Ue40d8000 and it always gave me problems. Now, after a factory reset done into the service menu it turn on normally but when I search channels I remain locked in choosing the type of signal (Digital and analogue, only digital or only analogue) and I can't select anything. After a few seconds it restarts and I can hear a clicking noise. What I can do? Thank you so much

If you hear clicks and restarts, one of reasons of this could blowed capacitors on powerboard. Search on google for that, you will find a lot info about issue, which is common from series to series.
But also there can be differen issue, e.g. damaged mainboard or so.
