Alaplap (rsag7.820.5001/ROH) csere előtt 10 mp után újraindult. Hisense logo képernyőn megjelent majd eltűnt és újból visszajött. Tv nem reagált semmire! Alaplap cserét követően tv bekapcsol led világít logo felirat nincs. Tv távirányítóra illetve a kezelőpanel ki/be kapcsolójára reagál standby módba kapcsol, hangszórók halkan sisteregnek. Itt elakadtam, ha valakinek van valami ötlete akkor szívesen veszem!
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

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