Από συνομιλία μου με την LG Αμερικής:
--ME: my full model is 50PA5500-ZH...not sure what's the difference between this and 50PA5500-ZB. Mine came with firmware version: 3.18.12, and I see a new 3.29.12 version that i'd like to update to.
--Ana: The letters after the model are for tech support only when they need to order the part. You can download the firmware in the website
--ME: However, when I insert a FAT32 USB stick (have tried both with 1GB and 512 MB), the update window won't show up. Instead the TV reads the contents of the stick, as usual (categories: photos, movies and music)
--Ana: Is the file unzipped? Is the USB drive empty from all content but the unzip version of the update?
--Ana: You need to create a folder named LG_DTV
--Ana: And transfer the content there
--ME: yes, I have created the folder LG_DTV, following LG's instructions
--Ana: You can try to use a different USB drive. If that fails we can send you a tech to update
--Ana: I understand, do you want to set the service call ?
Πιο εξυπηρετικοί από τους δικούς μας. Βέβαια το θέμα παραμένει. Αναρωτιέμαι αν αξίζει να κανονίσω tech-support appointment με την LG Hellas!
