Sziasztok!
A készülék tápja túlfeszt kapott .
A javításához már csak egy OZ531TGN ic-re lenne szükségem.
Ha esetleg valakinek lenne eladó kérem jelezze.

Sziasztok!
Említett készülék bekapcsolási kisérletkor villant párat a leden, majd visszaáll készenlétre. Ez idő alatt (amennyire mérhető) minden feszültség megjelenik. T-con ledje is villan egyet.. Gombról/távról is ugyanez a jelenség. Igazából olyan, mintha zárlat miatt nem engedné indulni, de ilyet nem mérek sehol. Van ezeknek esetleg valami jellemző hibája ami okozhatja?
Köszönettel: Kiss Z.

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
