hi.
a fenti típusú, működő saját plazmám-néha olyat tesz, hogy stby-ba kapcsolás után nem folyamatosan világít a piros led- hanem ütemtelenül (mintha kontakt hibás lenne!)villog!!
de csak néha---általában stby-ba kapcsolás után kékről átvált pirosra.
mostanában vettem észre és néhány órás működés után tett ilyet..
mi lehet a gyíkja???
valakinek van ötlete??
üdv: egon
Kedves kollégák!
Én még ilyen gagyi hibával nem találkoztam. Ha bedugom a lan kábelt a TV rögtön lefagy,majd kikapcsol és ujra indul ismét lefagy. Egyébként e nélkül tökéletesen üzemel. Az RJ45 aljzatot már kicseréltem. Zárlatot nem mérek a kimeneten. Nincs valakinek egy spi mentése vagy USB s firmware. Esetleg valami tapasztalat.

Sziasztok!
Háát ez hihetetlen, gyönyörűen megy a gép, de a táv jelét nem veszi :(
5-let?
Köszi!

Dear all,
this TV, Hisense H60N5705 installed in a conference room, turns off automatically a few minutes after being switched on.
The problem started to occur suddenly, during a video conference. It was switched on with the remote control, continued to work for a while and then switched off again.
The room technician changed the power cable (?), the HDMI cable (??) but the problem of course remained.
I asked if it changes anything by connecting the TV to another source but, even if it is left on the OSD menu, it stays on for a few minutes and then switches off.
So they took the TV (a 60’ which is not easy to handle) to the lab and asked me to check it.
I still have to open it up, but I don't have the schematic diagrams and should proceed by trial and error, although I imagine a problem with the power supply stage.
How do you suggest I proceed, since I don't do TV but RF ?
Thank you for any help,
Best
Maximus
