    Ill be honest I hardly know anything about antennas/radio waves when it comes to transmission distance etc so any help would be appreciated
    1. Increase length of transmitter antenna.

    2. Increase length of receiver antenna.

    3. combine 1 and 2 above.

    4. Replace with fresh batteries.

    actually there could be 2 problems. Either it is the transmitter, or the receiver.

    there may be just a piece of wire inside the plastic tube. Antennas have to be the correct length in order to get a SWR of 1:1

    Should I try to remove the plastic? Are antennas made for a specific band that matches the receiver or?

    It's a plastic coated antenna?

    You should get more than 10 feet range on 27mhz, what size antenna do you have on the transmitter, it may be possible to replace with a longer telescopic antenna however you would need to look at what ever passes for tuning on the transmitter output stages.

    if you can put some pictures up, and if you have the transmitter dismantled some pictures of the pcb(s) etc.

    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...

    Old Privileg 5.1 speakers remote control question
    by piipo
    Hi, I have an old Privileg brand 5.1 speakers. I have lost the remote control. I have an universal Harmony remote but there is no Privileg brand in it's software to add. Does anybody have an idea what alternative brand for a remote can I try instead? I'm attaching an image of what the speakers looks like. The image shows 2 main speakers, they are 5 + 1 in total. Thank you very much

    Schematic for Denon Remote Control RC1156
    by hemant_2222
    Hello Everyone,

    Hope everyone is enjoying their repairs at hand!.

    I am looking forward to get the schematic of Denon remote control RC1156. Actually long time no use of the remote leaked the battery thereby corroding few parts as well as the tracks.

    I was able to join few of them but the remote is still not working, so i am looking forward for your help, in case anyone understand the schematic or the remote circuit diagram and could me assist me in repairing it.

    Please refer to the attached picture, i think the voltage divider is missing...

    hitachi 75hl16t64u - not responding to remote control
    by dfear
    I have a hitachi 75hl16t64u tv in for repair and it is driving me crazy.
    It came in for a power issue which I have finally resolved by replacing the power supply.

    The current issue is that the TV does not respond to the remote control. I have replaced the IR sensor board with a used one but the fault persists.

    Anyone have a clue how to fix TV?

    FYI: I have checked the remote work s by pointing it at my camera on my phone....
