LG PDP42V5 Plazma hiányos kép (tippeket várok)
Sziasztok mesterek! Egy LG PDP42V5 Plazmát ajánlottak megvételre hibásan. Kaptam képeket róla amit megosztanék itt. Mivel plazmával még nem igazán volt dolgom szeretnék segítséget kérni a képek alapján mi lehet a probléma vele, javítható-e, érdemes-e megvenni stb. Élőben még nem láttam mert messze van.
LG 19LE3300 fordított polaritást kapott
Sziasztok, adott ez a készülék. Kamionban, "alternatív kábelről" is üzemeltették, és számomra érthetetlen módon fordított polaritást adtak neki. A panelen van pár szénné égett induktivitás, de csodálkoznék ha ennek cseréje után elindulna. Szerintetek érdemes ezzel foglalkozni? Esetleg volna valakinek pl. kijelzőhibás készülékből maradt működő vagy javítható panelja? Üdv. Tamás
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 42Pq2000 táp nem indúl
Üdv!

A fenti tv áram alá helyezés után relé kattan a feszek egy pillanatra megjönnek majd leáll. Addig jutottam, hogy a tápban ic701-et melegítve a gép szépen bekapcsol és működik. De a következő ki bekapcsolás után megint tilt. Az ic egy MC80f0708MHF13 mikrovezérlő. Került bele egy új amivel a helyzet még rosszabb. Azzal meg se nyekken. Gondolom ebben van valami program ami az újban nincs. Keresnék ilyen ic-t bontottat vagy felprogramozottat.
A táp száma EAY58349601 EAY459544701
