Sziasztok!
Tegnap hozták ezt az LCD-t, hogy durrant egyet, és azóta nincs kép rajt, a hang meg van. Szétszedés után, a tápban találtam egy szétdurrant icét, a pozíció száma N801 , és még a R810 szakadt. Nem találtam a tvéhez rajzot, a tápról sem, csak komplett tápot. A táp száma: HLP-23B01 RSAG7.820.1032, ehhez szeretnék segítséget, rajzot, vagy az ic típusát, és az ellenállás értékét. Köszönöm előre is!
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
