Pioneer plazma PDP-LX5090(panasonic belső?) nem indul, 11 villogás. (megoldva)
Sziasztok!
Nagyon nem kedvelem a plazmákat, mégis egy ilyet javítanék. Ismerősöm elmondás szerint, (miután hozzá került) egyszer beindult, többé soha. Átmérve hamar kiderült, nem dolgozik a PFC. Most már stabil 400v megvan. Bekapcsolást követően minden feszültség megjön, majd kb. 2 másodperc után kikapcsol és 11 villogás...  elvileg ez ha jól tudom ventilátor (meg sem moccannak) hibára utalna. Minden a négy kifogástalan, nem szorul. Külső tápról 12 volton 60mA az áramfelvétel. Próbáltam lekövetni miként is vezérelné őket, de elakadtam.  Lenne valakinek tippje mi lehet a gond, vagy tévútra vittem magam ezzel a venti dologgal? 
Köszönettel: Kiss Z.

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
Panasonic TH 37 PA 60E kiakpcsol 10-et villog
Helló! A tulaj ezzel a hibával hozta a készüléket, nekem ugyan már egy fél órája megy, de még nem kapcsolt ki. A szervízkönyv szerint vagy tuner vagy hangvégfok hibára utal a 10 villanás. Volt már vkinek ilyen hibája? A hangpanelon nem érzek semmilyen melegedést, hirtelen arra gondoltam, hogy vmelyik forrasztás hibázik. Holnap egy kicsit meghajtom, remélem úgy előjön a hibája, gondolom hátlap nélkül jobban hül. Üdv.: Ízirájder
