Panasonic TX-21S1TCP Ch.: Z5 megoldva! igeeeen :)
Sziasztok! Nálam van ez a szépség :) Életemben nem szedtem még szét Z5-öt, sőt azthiszem nem is volt nálam ilyen TV :) Tudnátok tanácsokat adni mire számítsak? :) Képcső brutál jó, A51EFS videocolor :) Annyit csináltam így este, h. hátlap leszed és ránéz... C562 elkó kezdi a belét szép lassan kitolni, plusz ha bekapcsolom a TV-t, akkor valami nyögésszerű hang van, majd síri csend. Csak azt remélem nem trafós lesz. Köszi előre a segédleteket! Üdv: Pityesz
Panasonic TX-43ESW504 mainboard helyettesítése?
Üdv mindenkinek! 
Fent említett tv nem csinált semmit, most lap csere után az a jelenség hogy bekapcsolásra 
a led zölden sűrűn pislog majd pirosan lassan. Közben a Panasonic logo balra csúszva megjelenik 
kis időre, háttérfény nélkül. 
Az eredeti lap TNPH1181 amit beletette az meg TNP4G633 
formára tök ugyanaz, több helyen azt írták hogy jó helyette. 
Valakinek van tapasztalata ilyenben?
Köszönettel:  Csirip
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

Andi

Sziasztok! Hozzám került a fent nevezett készülék. A tulaj annyit mondott hogy nem jó, szétkaptam, a vert. IC körül elég sok kh volt. Átforrasztottam és cseréltem egy pár elkót, a készüléket bekapcsolva egy pillanatra mintha indulna (jellegzetes hangok) megjelennek a tápfeszek de abban a pillanatban le is kapcsol és a készenléti LED folyamatosan villog. Volna valakinek ötlete merre keressem a hibát? Zárlatot még nem találtam. Köszönöm a válaszokat.
