    DeLonghi AC Remote only accepts 3V
    by cstout
    Hello all, I've been looking into this portable air conditioner's remote control and can't find what could be causing the problem - or possibly this remote is just terribly designed.

    The remote only works at exactly 3V - if I drop it any lower, using my bench power supply, to say, 2.9V then the remote will not flash the display and turn off. I don't have any AAA batteries that are exactly 1.5V each so I'm not sure if this remote is designed this way - to only use the freshest possible batteries, or if there's a failed component in the mix.

    I can't find any schematics...

    Toshiba 50lf711u20 fire tv remote not pairing
    by Mc_Millian
    Hello everyone,

    I was wondering if anyone could help my in pairing a remote with a Toshiba fire tv?
    The Tv model number is: 50lf711u20 Rev B.


    I've already replaced all the the circuit boards within the tv along with the I.R. sensor receiver.

    I've tried 3 different remotes which should be fully compatible with this TV.


    Oddly enough. A few if the buttons on all of the remotes actually work. Even without pairing...which makes no sense.

    The power button, along with the volume,back,select, and directional...

    HiSense 55A7500F won't obbey to remote after power on
    by edugimeno
    Hi! I have this TV set that does the following:
    1) I press the red power button on the remote
    2) The TV turns on normally
    3) After that it won't take any other command from the remote, neither power off, volume, channel, NOTHING
    4) We need to either pull the main cable or use the built in button at the bottom to select funcion OFF

    Then after it's off, it would again accept the TURN ON from the remote and same again

    BUT:
    -The remote does show the correct IR beam while observed thru a phone camera
    -The TV works fine while using the MiRemote...

    Pioneer VSX-522-K remote control not working???
    by tmhobadcap
    I have this receiver for at least 10 years. Usually, we just use the remote for turning on/off and adjusting the volume. Recently, the remote control started not able to turn the receiver on. Later, the volume also could not be adjusted by the remote control.

    At first, I thought that it was the usual problem which can be fixed by cleaning the contacts on the switches and the pcb. I opened the remote and clean it with alcohol. The remote did work again after that. But after one day, it did not work again. I opened it again and clean with alcohol and contact cleaner. Again it worked...

    Please help, where can I get a remote for my subwoofer?
    by rustinjust
    I’ve got a subwoofer that I’ve had for nearly 20 years, it did come with a basic remote which I’ve lost. It’s a generic make of subwoofer, I can’t see a brand sticker on it. It comes with 2 speakers.

    Question recently I’ve connected it up to my tv which has greatly improved the sound on my tv, however I’d like to be able to mute the subwoofer when ads come on or just mute it when the phone rings etc. I tried using a cheap all in one tv remote on the subwoofer and the volume button would only work to increase volume but not turn it down or mute it

    Is there...
