I recently bought a Semp TV which unfortunately uses a BT remote control.
I hadn't paid attention to that detail when I bought, as I already had what I thought was a similar Semp, only it's remote was infrared, not BT.
The problem started when the TV starting not responding to the remote.
The service people told me I had to take the TV and the remote to them, which was absolutely ridiculous.
So I could contact the manufacturer's customer service. They were very helpful.
The problem is this remote can operate with a minimum 80% of the charge on the battery, and they have to be alkalines., which mine were not.
You also had to pair the remote, which I didn't know I had to. When you pair it, you enter the BT menu and look into the remote setup. There you have the present capacity of your batteries. Of course mine were below 80%.
Semp should have designed this remote for AA batteries, not AAA, if minimum capacity was so quickly reached.
Switching for alkalines got the remote back to life, but I already bought ENERGIZER AAA ULTIMATE LITHIUM L92 for it, following a friend's recommendation.
My question to you has two parts:
1) Is there any universal Bluetooth remote control I can use. Which one? I think the frequencies must be the same, and I don't know mine.
2) Is there any cell phone remote control app that I can try? It could save me for emergencies.
Besides I'm investigating the viability of a DIY solution. Using an external dual AA box to replace the power, perhaps using dummy AAA batteries on the inside. Comments on that, please?
Please suggest any other solution for my problem, if there's any. Except changing the TV.
