Panasonic projektoros tv, TX-47P
Panasonic projektoros tv-nek (TX-47P) olyan hibája jött elő, hogy a menüben a hangerőszabályozás látszólag működik, de mindig egy bizonyos hangerőn szól.Ha teljesen le van véve a hang, akkor elnémul, és már az első erősítés után is max. szól . Mi lehet a gond? Lehet ezt pl resetelni?? Nem látom a service könyvében, de még teljesen nem ültem neki,lehet nem lenne értelme.Tud ebben valaki segíteni? Előre is köszönöm!
Panasonic TX-P50U10E 3 piros villogás
Sziasztok! Adott a fenti készülék, bekapcsoláskor 3-szor villog pirosan a led, és nem is kapcsol tovább.Elvileg ez valami hibakód, de számomra zavaros amit találtam a neten leírásokat, nem tudom melyik panel lehet a ludas. Esetleg ha tudná valaki vagy tapasztalt ilyet kérem jelezze.
Panasonic TX-15LT2
Sziasztok! A fent nevezett TV-vel olyan problémám van, hogy analóg kábeltévénél csak néhány adónak működik a hangja (csak a NICAM stereo adók). Találtam itt az oldalon service manualt (panasonic_tx-15lt2_chassis_lh1_sm_[ET].pdf) hozzá amiben benne van a szervízmenü elérése. Sikerült is belépnem és végignéztem a beállításait de sajnos nem találtam meg hol lehet beállítani. Sajnos a tv menüjében nincs lehetőség a hangnorma módosítására. Melyik beállítást kellene módosítanom ahhoz ,hogy jó legyen? Üdvözlettel: Medve3
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
