Hello. Main Chinese 715G6947-M0G-000-004K. As in the subject, the Philips logo and reboot,. First restart with Logo the second without and all over again. What's done. After being brought by the client it displayed the text PHILIPS and restart. I downloaded the firmware from the website and after the upgrade (holding the joystick pressed) the same restarts but with the Philips logo, not the inscription (i.e. the upgrade did). You need a batch of U405- MX30LF1G08AA-TI or a hint of what to cling to.
