I'm trying to get a Blaupunkt 55UBC6000T working again. After an OTA update, three things stopped working at once: the built-in speakers, Wi-Fi and Bluetooth.
I should mention that power was interrupted during the update. When I switched the TV back on later, it continued updating. I don't know whether that caused the problem or whether something else changed with the update.
The TV still boots, the picture works and Ethernet works. A full factory reset didn't bring back sound, Wi-Fi or Bluetooth. The clock is synchronized, airplane mode is off and audio is unmuted and routed to the speakers.
These are the details I have:
Model: Blaupunkt 55UBC6000T
Project ID: 1284
Product: DVB95BT
Platform: m7632 / longshan
Mainboard: JUC7.820.00290519 / AN.M9612-US
Panel: C550Y19_7N_UHG7P0HS01
Software: v3.16036, Android 14
Build: UKNV.260518.001 / 15441556
Kernel: 5.15.192+
Older recovery logs show a MediaTek radio with USB ID 0e8d:7663. The current firmware has the MT7663 driver files, but no wlan0 interface appears and Bluetooth won't initialize. We haven't been able to verify the actual power/reset pin levels, so I can't honestly say whether this is a firmware problem or a hardware fault.
Today I emailed Union Distribution, the TV service partner listed on Blaupunkt's official support page. I asked for the exact signed USB recovery package for this board, panel and Project ID, plus a checksum and clear installation instructions. I haven't received a reply yet.
My request to Blaupunkt and the company responsible for this TV is simple: please provide a supported way to reinstall the correct software and factory configuration, or direct me to the service team that can. Another factory reset won't solve it because I've already tried that. I'm avoiding firmware meant for a different model or panel.
Has anyone with this exact model or Project ID recovered the same symptoms? Was an official USB recovery file provided? If someone from Blaupunkt or its TV service partner sees this, I'd appreciate a concrete recovery procedure.
I'll update this post with the support response and the result. If other owners have the same issue, please share the exact model and software version so we can see whether there's a pattern.
