Sziasztok !
Az adott készülék kezdetben eldobálta a wifit. Ezután LAN kábellel használva működött jó ideig.
Most viszont ennél is szakadozni kezdett a hálózat. Minden egyéb eszköz tökéletesen működik a routerre csatlakozva. A router portok felcserélése,kábelcsere nem segít..
Mi döglődhet a TV-ben ?

Üdv Kollegák !
Tegnap hozták a fenti gépet,mindkét hangszóró zárlatossá leégve, hangvégfok ic (tda 7269)szintén.
Cseréltem ic-t illetve a 2db kicsatoló kondit és természetesen a 2 hangszórót. Most jó és éppen járatom.Érdekes, hogy a (félig)döglött végfokból és a leégett hangszórókból (1-2ohm) viszonylag erős "szirénahang" szerű zúgás hallatszott. A végfok ic egyik kimenetén de a kicsatoló kondi előtt teljes tápfesz kint volt, a másik kimenetén az odaillő féltápfesz. Talán valami gerjedés lehetett rajta. Most javitva, a végfok hűtőbordája még langyosnak sem mondható. Érdeklelne a véleményetek.
Köszönettel: Csinti
Dear community,
Please help me solving my issue with my LG OLED55CX3LA TV.
I have this TV since 3 years, never had an issue, until last month, when It suddenly start to freeze. It stuck on white/ or in currently displayed picture, got some pitching noise, and 5-6 seconds later the TV shuts off by itself.
The solution so far is to restart it by the power button, or the power socket, within 10 seconds.
The problem occurs very rarely, sometimes early morning, sometimes 2 days without problems. I have played some HDR videos continuously, with no problems.
I have read about these issues on LG OLED, and most of the cases were caused by overheat of the main processor.
Also read about thermal paste. I have opened my TV and yes, thermal paste was hard as rock.
I have cleaned the processor carefully, and used profesional thermo paste, but that does not solve the problem, unfortunately.
Also, I have done hard reset, used latest firmware update, tried without HDMI inputs, but the problems still persist.
As the problem is not coming very often, I am in research of the correct solution.
I was read that the main board can be used from different LG OLED TVs, and even can get a better processor, kinda upgrade.
Give me please your opinion and advice what is the best solution.
Thanks,
Kalin
