Panasonic TX-42X20E 4-et villan
Üdvözletem! Letöltöttem a mnuálját abban az áll, hogy a tápja hibás. Mérve valóban zárlatot találtam, de a jobb oldali modul a hibás. 2 db RJP30E IGBT zárlatos volt benne. Kivettem őket így megszünt a zárlat. Megpróbáltam próbára beindítani a készüléket aminek elsőre zöldet villant a ledje, de ismét zárlatba ment. Újfent ez a modul hibásodott meg. Azt szeretném kérdezni, hogy van értelme megrendelnem ezeket az IGBT-ket, vagy inkább komplett modult érdemes? Üdv.: Ízirájder
Panasonic TX-L42ETW5 Device does not start anymore, stand-by LED lights up red, no SOS error code
Manufacturer: Panasonic

Type: TX-L42ETW5

Chassi: LA35



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

Üdv! A fenti tv néhány naponként ill. hetenként röpteti a sorvégtranzisztort. Egyébként tökéletesen működik. A sorvég nem melegszik. Sanszos kondikat cseréltem.Van valakinek ötlete? Köszönettel: töröká
TX-P42G20E Panasonic ( plazma ) készenlétből nem indul
Sziasztok! Kérdésem az lenne, hogy eme készülék videó boárdja ( TNPH0838 ) javítható-e, érdemes-e vele foglalkozni vagy másik kell bele? A hűtőbordát melegítve szépen beindult és működik azóta is. Az elkók le lettek tesztelve. Ha valakinek van ilyen működő boárdja és megválna tőle, kérem jelezze. Köszönettel: Jani
