Ok, so far I’ve “resolved” it in the following way:

• got a high-quality HDMI cable
• Enabled HDMI-CEC on the Android TV box

Now I can turn on the TV using the Android TV Box remote, and the TV automatically switches to HDMI5. However, the HDMI5 option is still missing from the TV’s Source menu. If I switch to HDMI1, there's no way to return to HDMI5 except by powering the TV off and on again.

The repair took quite a while, so I’m not 100% sure whether the previous SSB behaved exactly the same, but I believe the HDMI5 option was present in the menu before.

Looks...

I've got numbers from stickers:







I do not see any option to change number of USB or HDMI ports in SAM.
Also I guess 12NC numbers does not really mater, the features are higly likely controlled by Option Codes.​​​...

Sorry for the confusion, there is a typo in the last sentence — it should be “I have 65PFL9708S/12.” So the only difference is /60 vs /12 only....

Hello everyone!

I recently had to replace the SSB in my Philips 65PFL9708S/12.
Fortunately, I managed to find a board with the exact same part numbers:

• 3104 303 54946 B
• 3104 313 66186 B

The TV works fine after the replacement, except for one issue: the “HDMI 5” input no longer appears in the menu.
I could live without it, but on this model HDMI 5 is the only port capable of handling 4K.

Here is what I’ve already checked:

• Updated to the latest firmware (173.67)
• Double-checked both rows of Option Codes — they match the original board:
  • 33347 04648
