Sziasztok!
Egy Vestel 17MB95M alaplap a fenti TV-ből lett kibányászva, és bele akartam (akarnám) rakni egy másik TV-be, de az eredeti TV-ben más kijelző volt, nem állt össze a kép rendesen. Van fenn a neten rengeteg Vestel firmware ehhez a laphoz, gondoltam majd valamelyik jó lesz. A kép jó is lett, viszont azóta nem talál adókat koaxon és nincs hangja. Kb. 30-40 update után már elegem van az egészből, visszaállítanám eredeti állapotba, mert ez a lap így használhatatlan, viszont nincs meg az eredeti laphoz való firmware-t. A Panasonic oldalán levő firmware-k között ez a típus nem szerepel. Hátha nektek jobb szemetek van, és ráakadtok egy letöltésre...

Hello!
Bekapcsolás után hibátlan kép jelenik meg rajta és egyszer csak visszaáll készenlétbe.
A készenléti led 1-et villog.
Tudja valaki milyen hibakód ez?
Köszi!
Megoldva.
Led sorok cseréje után tökéletesen működik.

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
