LG 26LC2R tápegység javítást követően nincs szín tunerről. (megoldva)
Sziasztok! Nevezett készülék tápegység hibás volt. Javítást követően a próbák során derült ki, hogy tunerről nincs szín. Más bemenetről rendben működik. Olyan mintha nem megfelelő normára lenne állítva, de nem tudom ezt hol lehetne módosítani. Esetleg tudja valaki?? Köszönettel: Kiss Zoltán (táv és készülék "OK" gombjával való belépést követően egy reset segített)
LG OLED55CX3LA freezes and shuts down
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


 
LG RE-29FB51 kikapcsolgat
Üdv Mesterek! Adott ez a MC036B sasszéjú masina. Bekapcs után 8-10 másodperccel kikapcsol stbyba, utána vissza lehet rögtön kapcsolni, de ua. a vége. Képernyő sötét, fűtés alig van, feltekert G2-nél látszik a /raszter/ nagyon lecsökkent sorméret EW hibával. Nosza, kicsatoló és a többi impulzus kondi méregetése, cseréje, - mérve jók - hiba ua. Eltérítőtek. levéve átnézve semmi gyanús. A sortáp indításkor feláll szépen 135v-ra , de a sor indulásakor leesik 118-ra, ha a sor leállt, egy pillanatra újra jó az értéke aztán stby.A primer oldalon a pufferkondinál ugyanez idő alatt előszőr 320V, majd leesik 260v-ra ,ahogy leállt a sor újra 320v, aztán bont a relé.Pufferkondi és a 100uF cserélve, a sec.oldalon 100uF/100v cserélve, minden ua. nekem STRF gyanús, de talán valaki jobban tudja... Köszi
