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
Hello,
I have this LCD TV which has a very white screen, the picture is visible. I could not find any fault on the CCFL Lamp inverter and was suspecting the T-Con panel of failure. The T-con panel is integrated in the control board. What i did is using "freeze it" cold spray i sprayed one of the IC's and it cured the fault. Perhaps the IC needs to be replaced. The part number is AS15-G. This component is not available for purchase in south africa and i would need to import it from china. This part is a LCD voltage buffer.
Regards
Angelos
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 ?
Sziasztok a fenti tv-hez keresnék nand flash mentést.
