Hi everyone. At the beginning sorry for bad English, I came from Poland. I have a mp4 player named LASONIC VP-04sbk. One day, I wanted to switch it on but he did not run. I have blank white screen on it. Inside there is AK1025 and JCT006 tft lcd. After few upgrades the effect with lcd is the same but mp4player start plays music correctly. I put buttons blindfold and it start playing music. Has anyone have a firmware for this player or some informations how to repair it??
