Sziasztok!
Lenne itt egy LG T710B monitorom ami nem kapcsol be. Szétszereltem és azonnal feltűnt, hogy a C774-es (160V 47uF) számú kondi kifüstölt ezt kicseréltem de továbbra sem semmit nem csinált. Elkezdtem mérni a panelen és rábukkantam egy meghibásodott mosfetre (Q719). Ezt is kicseréltem. Így már ad némi jelet magáról. A zöld led pislogni kezd és a panelen lévő relé ki be kapcsolgat.
E probléma felderítésében kérném a segítségeteket.
Előre is köszönöm a válaszaitokat!
Ebből a rajzból dolgozom: http://data.manualslib.com/pdf2/42/4183/418212-lg/t710bh.pdf?44d2aecc759ad522a05cc82a9da81737
Szevasztok T. Kollégák!
Tárgybeli monitor táp ic tető lerobbant. Ügyfél szétkapta, a típusjelzés nincs meg. Olyan a bekötés szerint, mintha DM0565 széria valamelyik egyede lenne, de jobb lenne nem találgatni, hogy melyik.
Ebben kérnék segítséget.
Köszönettel,
elbandi
Hi all,
I see in various Sony documentation a term called "special PAL signal" or "Ant Pal signal". It is used to calibrate the color decoder. The signal is supposed to be available from a signal generator (exact model never referenced).
I have a Leader 404 PAL pattern generator. While not the most complicated, it is one of the industry standard machine. Also I don't remember seeing a fuction like special-pal in more expensive generators.
Can someone explain what this signal is, and what generator is known to produce this signal? Thanks!
Attached are waveforms and description shown in service manuals, from PVM9220 and 1440 respectively.
