Using firmware for the wrong panel (even on the same board) can result in an upside-down image or solarized colors. Always match the Panel Model (e.g., LC546PU1I01) listed on the sticker inside your TV.
Telefunken does not always provide public direct downloads for legacy boards. Check specialized repair forums like KenotronTV or Forum-Monitor for the specific split archive you need.
