Sziasztok!
A fenti gépnek egyik napról a másikra aHDMI benetről eltűnt a képe.
Kábelhiba kizárva, több jelforrásról kipróbáltam a hiba ua.
Ehhez kérném a segítségeteket.
Köszönettel: Laci
Sziasztok!
Van egy LG42LX6500 típusú tv, ami a sajátom. Teljesen hibátlanul működött, amíg észre nem vettem rajta, hogy a HDMI-n rákötött Smart Box-on nincs kép. Azt hittem, hogy a box romlott el, de a másik tv-n működik. Ekkor jöttem rá, hogy az 1080p nem megy a tv-n, csak az 1080i. A Smart box meg 1080p-n adja a képet. Mi okozhatja ezt a hibát? A tv adásoknál is a full HD adások 1080i-ben jönnek. Találkoztatok már ilyen hibával?
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
