Üdv mindenkinek!
A fent nevezett készülék a linken látható hibát produkálja, szerintetek mi a hiba forrása, a kijelző adta meg magát? Köszi
Sziasztok!
LG 47LN5400 TV a következő hibát produkálja: bekapcsolásnál egy pillanatra van kép, majd eltűnik. A készülék bekapcsol mivel hang van. Kikapcsoláskor szintén egy pillanatig van kép majd elhallgat...
Lenne valami tipp hogy mi lehet a hibája?
Köszönöm!

köszönöm!

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
