LG 32LZ50P televizió PSU meghibásodás
Üdv. mindenkinek!
Kaptam egy televiziót, azt csinálok vele amit akarok, de nem működik, mondta az illető. (be sem kapcsol)
Típusa: LG RZ-32LZ50
Szétszedtem, amúgy feltűnt elsőre, hogy a PSU TNY268P IC teteje el van füstölve (hiányzik)
Kérdés: mitől éghetett el (szállt el a teteje)?
Cseréje esetén esetleg bekapcsolhat?
42lv375s - LG led Televízió alaplap csere után kicsi a kép
Szép estét az uraknak.
Fent jelzett televízióban alaplapot cseréltem. Bekapcsol, működik minden funkciója .
A kérdésem a következő : ez egy 42" os televízió de kb egy 32" os nak megfelelő képet ad a képernyő bal felső sarkában.
Az alaplap egy bontott darab , Hol tudnám a képernyőre optimalizálni a képet ?
A menü és minden más jó . Csináltam 2 fotót  .  --- Tehát a menükép bal felső "" előnézeti "" képén látható az állapot , ez van teljes képernyős módban is .
A menü teljes képernyős módban , jól működik.
Válaszaitokat köszönöm !
LG50PJ250ZC plazmán hang van, kép nincs.
Sziasztok! Tudtok ebben segíteni? Még halvány derengést sem látok a kijelzőn. 5V, 60V, 205V rendben. Az YSUS panelről a kijelzőre menő 5V is rendben. Mindent jónak találtam az Y és ZSUS paneleken. Kikapcsolható, bekapcsolható, csatornát vált, hang megy rendben, de kép sehol semmi..... Vajon mi lehet a hibája? Mellékeltem képeket a panelekről. A segítséget előre is köszönöm. Üdv:Zoli
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
