Sziasztok!
Kis segítség kellene a fenti készülékhez 21 "-os .Lehet volt már itt is róla szó azért leírom mi van. A tulaj elmondása szerint az utóbbi hónapokban a tv bekapcsolás után nem mindig indult.Ezen ő ütögetéssel segített és indult végül egyszer menet közben állt meg és azóta csak kis led villog.A készüléket kibontva komoly kh-t nem találtam és zárlatos dióda illetve semmi sérülés nyom .A nagy táp is beindul de le is áll. A sorvégtranyón is mérek feszültséget egy pillanatra és ennyi.Van valakinek ötlete? Előre is köszi!

Hello everybody,
I could determine or measure the following with the device:
Device does not start anymore, stand-by LED lights red when device is plugged in and flashes red as soon as an IR command (key press) is sent via the remote control. Voltages of power supply STB 5V and signal LCD_TV_SUB_ON come from A-board. Power supply starts, supplies P15V and SUB1.1V, 1.5V, 1.8V, 3.3V, 5V, HDMI3.3V and USB5V are generated on the A-Board (stand for about 2.5 seconds). Then signal LCD_TV_SUB_ON goes low (voltages go away to STB 5V) and after about 2 seconds back to high (endless). What is missing is the voltage PNL12V which is switched on by PANEL_VCC_ON2. PANEL_VCC_ON2 always has a low signal and does not change its state. Power supply also provides for the 2.5 seconds the 24V for the backlight. Clocking of LCD_TV_SUB_ON starts immediately after plugging in the mains plug (also without IR command). SOS error code is not output. The over-voltage circuit in IC 5000 pin 7 also does not respond. Attached is the timing diagram from the technical training of Panasonic where I have drawn until when the boot process behaves normally.
In my opinion a mistake on the A-board? Does anyone have a tip?
greetings
Andi

Kedves kollégák! Sziasztok!
Egyszerű hibának tűnt de elakadtam.
Bekapcsoláskor kép-hang tökéletes, néhány perc után,ez változó) a hang elmegy és csak erős sistergés hallatszik.
Norma marad, váltásra nem változik. Hűtésre fűtésre nem reagál.
Újra indításnál van hang bizonytalan ideig. MSP3415 helyett MSP3410-et tettem ezzel is ua.
Kvarcot cseréltem. Esetleg egy memó tartalmat belepróbálnék, bár nem hiszem, hogy az a hiba.
Tápfeszek megvannak. Persze sok maniókát nem dobnának rá.
Hátha találkozott már valaki ilyen problémával.
Köszi,üdv,kovi
