LG 32LF7700 tévének van vonalszintű audio kimenete? ELNAPOLVA.... LEZÁRTAM
Sziasztok! Adott ez az LCD TV. A tulaj szeretne egy 2.1-es rendszert hozzákötni(mélyláda, kisebb hangdobozok), picit feljavítani a tv hangját. A SCART-on kinyerhető ez az audiojel? (azért kérdezem, mert megvette a SCART-RCA kábelt, de az erősítő rendszer meg sem mukkan. :cry: ) Köszönöm a segítséget: F. Új fejlemény: fejhallgató kimenetről meghajtotta a rendszert. Elmondása szerint a TV-t 60-70 egységre fel kellett hangosítani, h szóljon valamennyire, de ilyenkor már torz a hang. :((( Kaptam képeket a TV hátuljáról, de nem lettem okosabb... :((( Marad a végső megoldás: A TV gyári hangszóróiról a jel leosztása, majd ezzel a láda( :) ))) meghajtása. Sziasztok! A tulaj nem jelentkezik, talán már nem is érdekli... ez van....

LG 50ps8000 piros pöttyök megoldva
Sziasztok Vettem magamnak egy z-sus hibás 50ps8000 res plazma tv-t. Kicseréltem 2db zárlatos fetet és meghajtását és el is indult a tv. De sajnos piros zizikes pöttyös a kép. Ami furcsa hogy fényerőre nem változik csak a fehér tónusra szaporodik a piros. VSS feszültséget feltekertem 203v ig így javult a helyzet de csak keveset. Mi okozhatja ezt? Kisebb elkókat az y-sus és z-sus on mind kicseréltem a hiba változatlan. már vagy 1 hónapja vacakolok vele és tanácstalan vagyok mitől lehet ez..
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
