I salute you with respect! At this TV SELECLINE LE-2219D,the mainboard CV9203L-Q24 was changed. It is equipped with T215HVN01.1 display,and U3 = 25Q32 flash memory. After that, it works correctly, but the image is reversed vertically and obviously no longer recognizes the original remote control (goes with Made for You Code 5224). The Changed CV9203L-Q24 mainboard is turned from TV Orion T22D-PIF-LED. Should a software suitable for SPI U3 = 25Q32 of this brand or a USB update software for SELECLINE LE-2219D, maybe someone knows this or another method. In the Service Mode I have not seen anything that is useful to this problem . Thank you in advance!
Sziasztok!
Hozzám került ez a tv azzal a jelenséggel hogy táp megjelenésekor kék a led, 3 mp után pirosra vállt - és ezután sem gombokra sem távirányítóra nem reagál. Minden táp rendben, stabilizátorok kimenetei rendben.
Egyetlen lehetőség a szoftver frissítés. Sajnos a JUC7.820.00085966 chassis-hoz sehol sincsen dump, még a remont-aud sem hoz semmit.
A megoldás: http://aftersales.changhong.cz/firmwaresearch/
oldalon a gyári szám megadása után letölthető egy MERGE.bin file. Ezt beleírva az SPI eepromba csodálatosan működik a készülék. Érdekes hogy az eredeti tartalom 8MB körüli, ez meg csak 3.6Mb - tehát az eeprom második fele üres.
Valószínűleg minden CHANGHONG típushoz lehet itt firmware-t letölteni. Nálam már legalább a negyedik készülék ezzel a névvel, tehát nem lesz ez ritka. Bár a többinek nem szoftver gondja volt.
Köszönöm a figyelmet!
