Applies to: AKASH STB Model-3 in Bangladesh, using its currently linked English manual. The older HD STB manual describes the prompt differently; match the box and follow its displayed instructions. This is not an AKASH Go streaming-app guide.
Match your symptom
| What you see | What to do next |
|---|---|
| Prompt after inactivity | Use the Model-3 prompt response below. Test navigation and note whether the timer restarts. |
| No prompt or shutdown while using it | Treat this as a separate power/ventilation fault. Check the original adapter and clear space safely; do not assume a timer. |
Work through these checks
Identify the screen and timing
Check the Model-3 label and write down the warning before pressing buttons. If the TV alone says no input, confirm its existing HDMI/AV source with the TV remote. If receiver menus still appear, the screen is not evidence of total power loss.
What the result means: Separate receiver standby from TV sleep or the wrong input.
Respond to the Model-3 inactivity prompt
At that prompt, the Model-3 manual says to press a key other than OK to cancel standby and restart the timing. Use a normal navigation key and confirm that the box responds. My Settings → Standby Settings controls Auto Standby; the manual treats the three-hour active-standby feature separately, so do not present that menu as a guaranteed disable switch.
What the result means: If this works, retain settings and check the original viewing task.
Check unexpected shutdown safely
For a different fault, inspect the accessible original adapter connection without touching damaged parts. Keep more than 10 cm clear ventilation space, remove objects covering vents and keep the box away from heaters. Repeated loss of power during active viewing needs AKASH support. Preserve channels: factory reset erases them and is not a standby diagnostic test. Never interrupt an active software upgrade.
What the result means: Save observations for support; no casing access or speculative firmware.
When to stop and get help
Stop for burning smell, sparks, liquid or damaged wiring. Do not open the receiver or adapter. If shutdowns continue during active use with adequate ventilation, ask AKASH for service rather than repeatedly restarting or loading USB software.
What to tell support
Record whether the prompt appeared, which key you pressed, whether the front light stayed on and whether it happens while navigating. Share serial/account details only privately with official support.
Common questions
Can I disable this with Auto Standby?
The Model-3 manual distinguishes fixed active standby from the adjustable setting. Do not assume one changes the other. Follow your actual screen and ask AKASH about software-specific behavior if it differs.
