Üdv. kollégák.
tudja-e valaki, a TF2907HEU TV szervízmenübe hogyan juthatok be.
Egy kis képgeometrika beállítást kellene eszközölnöm.
A segítséget előre is köszönöm
Geri.
Üdv!
Lenne egy Hisense Tcon, ami fogta a maint.
Volt rajta egy SMD 10u ami zárlatos, ill a V3 pozícióban egy sot23 valami, (1. kép, bal alsó sarok) aminek méregetés közben levált a teteje... A V4 pozícióban is, van egy ugyan ilyen. Ezek a Tcon tápjában vannak.
Mind a 3 lába be van kötve.
Mik lehetnek ezek?
kösz

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
