Can Transmitter Be Fixed?

Hello,

My Swing IR headset is outside of warranty period. Recently headset's receiver started experiencing disappearing audio for short intervals and returning. When audio is missing I can still hear radio-like hissing noise on a background which tells me receiver is working.

Then audio completely disappeared and I only hear hissing noise. I noticed that 4 red lights that are normally supposed to be on the fron of transmitter no longer turned on so I think the problem is in transmitter.

Can it be fixed?

Thanks.
 
I see nobody answered you (yet ) on avsforum, I don't think you are going to get any information on the internal circuit of this unit.


Human Technik distribute Swing --I know because I got a Swing unit many years ago through Scotland,s Social Services for TV listening ,comes with velcro to stick on a small mike to one of my Tannoy monitor speakers I have attached via an old Sansui 70,s amplifier connected to the TV --yes it still works and I just looked at the label on the back .


The one I have is the industrial model built to a higher spec but I cant get a circuit diagram for it although its still working .


To answer your question I don't think you will have access to parts which are SMD although the SS will replace mine if it breaks down.
 
Because my unit has a mike input used for hearing problems and is fully adjustable not for basic entertainment.


I do have other inputs available but not used nor connected to the TV.


My amplifier is connected to the TV via my satellite box ( Technomate

TM-7102-HD- T2 Super which is HDMI connected ) .
 
+1 dangus - That sounds reasonable to me. In the last few years I've replaced small and medium electrolytics on everything from CRT TVs, flat screens, and DTV converters, even a refrigerator (true story! - saved a two-day wait for a $46 part).

One of the supplies could be 'pumping' - going full voltage to well below - will likely keep the microprocessor reset, as it isn't correct and stable long enough to finish off the reset delay.

Oh, and, those repairs just mentioned -- Service Manual either not available or hadn't come in yet.

This is only safe/possible on the line-isolated secondary side. (I assume you do not have an isolation transformer - another bit of kit to consider for the future.)

Look around in the power supply area (transmitter) for leaked capacitor guts, or one that changes the behavior when you sub another across it -- without removing the suspect, just bend the leads on the substitute cap into a 'bow-legged-cowboy' pose and make contact.

Cheers
