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
Tisztelt kollégáktól szeretnék segítséget kérni, Kedves tulajdonos úgy gondolta firmware frissítésbe kezd ezen a tv-n de nem volt kellően körültekintő, nem bele valót töltött fel rá, azóta a készülék azon kívül, hogy ha az érintő gombhoz érve csipog semmilyen életjelet nem ad,
A main típusa :RSAG7.820.5870/ROH
Az lenne a kérdésem, aki, akik találkoztak már hasonló esettel, hogy van mód lehetőség életre kelteni, vagy szobadíszként lehet kerülgetni.
Esetlegesen hogyan lehet firmware-t frissíteni benne hogy újra működjön ?

hi.
hozzám került tartós vizsgálatra a fenti plazma-a biztosító nyártól mostanáig vajúdott rajta.(villámos volt)
átnéztem-nincs kép,ymain halkan vísít,
kiszedtem az y maint és találtam rajta "értékváltozott" alkatrészeket,ja az stk 795-844 is gyanús,mert minden ami rossz az stk hibrid körében van.
találtam rajzot a tanyán,de hiányos-pont ez a rész hiányzik....
lenne -e valakinek rajza,vagy tapasztalata hogy érdemes-é foglalkozni a javítással-esetleg keressek panelt??

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
