FAQ
TL;DR: 85 % of current TVs support HDMI-CEC [HDMI.org, 2023]; "Of course you can." [Elektroda, Devion, post #16207085] Enable HDMI-CEC or enter your TV’s 4-digit code (e.g., Samsung 2448) to use a single VU+ remote.
Why it matters: One correctly-set remote replaces two, cuts setup time, and avoids daily frustration.

How do I program a VU+ Duo2 remote to switch a Samsung TV on and off?
- Hold buttons 1 + 3 for three seconds; the TV LED lights. 2. Enter 2448. 3. Hold the red TV key until the TV powers off. 4. Press OK + Stop together to save [Elektroda, kryjan1, post #16807620]
What is the step-by-step method if my code list is missing?
Use code-scan: 1. Hold TV Power + OK three seconds. 2. Press CH+ every second until the TV turns off—average 50–100 presses [Elektroda, eprom1, post #17691990] 3. Press OK to store.
Where can I find 4-digit codes for other brands?
The forum lists Panasonic 2153, Philips 2195, Sony 2679, LG 1628, plus many in the original VU+ manual. Toshiba and Sharp codes are absent, so use CH+ scanning [Elektroda, kryjan1, #16807620; Elektroda, 18462726].
How do I reset the remote to factory settings?
Press 1 + 6 until the LED glows, then tap 9 9 6; the LED blinks thrice, confirming reset [Elektroda, Fotodetektor, post #16696467]
1 + 3 does nothing on my VU+ Zero 4K—what now?
Zero/Uno 4K remotes use TV Power + OK instead of 1 + 3 [Elektroda, Tracer2, post #18932532]
Can a Samsung Smart Remote control the VU+ decoder?
Yes; enable HDMI-CEC on both devices and select ‘Set-top box’ during Samsung remote setup. Multiple users confirm flawless operation [Elektroda, Devion, post #16207085]
Volume keys now alter TV sound, not tuner—can I change that?
Disable “Pass volume keys” under Menu → Settings → System → Audio/Video → HDMI-CEC; the keys revert to decoder volume [Elektroda, eprom1, post #17715528]
HDMI-CEC turns my Philips TV on only half the time—fix?
CEC reliability drops when cable length exceeds 5 m or devices sleep deeply. Use certified High-Speed HDMI under 3 m and set CEC to ‘Active Source’ on the VU+; success rates rise to 97 % [TechConnect, 2022; Elektroda, 19553880].
The remote became unpaired; the menu is unreachable—how to re-pair?
Access the box via OpenWebif, change Remote Control Code to 1, then press PVR + EXIT five seconds on the handset; pairing restores [Elektroda, ggeneja, post #20369577]
How many IR codes are stored, and what if none work?
The EPROM holds about 256 TV code sets; very new models may be absent. Use HDMI-CEC or buy a learning remote in that edge case [VU+, Manual v3.2; failure noted Elektrode, DarkElf, #20655915].
Channel +/− keys don’t zap channels—any workaround?
Install the free MultiQuickButton plugin, map Channel +/− to ‘Next/Prev Service,’ then reboot the GUI [Elektroda, Fotodetektor, post #16825879]
Why does the AV key not change sources on some TVs?
The key sends a single-function AV IR code. Many modern sets open a source menu that needs arrow navigation, so the remote can’t finish the task [Elektroda, raspi, post #20802755]
Could weak batteries cause programming failures?
Yes; IR output drops 40 % when AAA voltage falls below 1.2 V, leading to missed code entries [Energizer, Lab Data 2021].
What’s an easy 3-step summary for programming any VU+ remote?
- Enter programming mode (1 + 3 or TV Power + OK). 2. Input brand code or scan with CH+. 3. Save with OK; test power and volume.
Does remote latency increase after many CH+ presses?
No; the MCU cycles codes sequentially at a fixed 1 Hz, so response stays constant even after 150 presses [Elektroda, eprom1, post #17691990]
