Gépkönyvet, kapcsolási rajzot keresek a fenti LCD TV javításához.
Bármilyen javítási tapasztalatnak, információnak, tanácsnak örülnék. A hibajelenség elég kusza: rövid, bizonytalan működés után lefagyás.
Az általános dolgokat már nézegettem.
Köszönöm a segítséget!

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

Sziasztok!
A műhelyemben van a címbéli készülék.
Tudomásom szerint legalább 3 féle alaplemezzel szerelték.
TF2907HEU néven legalább 5 féle eeprom tartalmat leltem a neten, de tökéletesen egyikkel sem működik.
A vadászat eredménye annyi, hogy hasonló processzorral készült, de más chassi-jú készülék tartalmát betöltve életre tudtam kelteni, de rendkívül sok agyalással, OP bitek kisérleti átírásával.
A gondom az, hogy csak manualisan tudok csatornát keresni és mindegyiket külön-külön finomhangolni is kell.
A geometriát sok küszködéssel sikerült béállítani.
A szervizmenübe lépve pedig, a bal felső sarokban megjelenő "M" betű nem piros, hanem zöld lesz.
Ezért kérlek Benneteket, hogy amennyiben van a birtokotokban a csatolmányban szereplő adatokkal kiírt tartalom, vagy Nálatok ilyen készülék segítsetek ki.
Más tartamak nem érdekelnek. Már így is túl sokat dolgoztam rajta.
Köszönöm, ha utána néztek.
Üdvözlettel! tnema
