Question about Projection Televisions
Samsung TV does not have a jack to connect a sennheiser TI250 unit. Tried work around by going thru an amplifer (TEAC AG-V8050) to power/feed sennheiser signal. This was set up by another person and I didn't check out the specific hookup-dumb! It has stopped working and I can't figure out how the hookup worked-none of the manuals cover this.Does anyone know about solving this problem? My wife is fighting cancer with a severe hearing loss and this is her LIFE SUPPORT!
Ok if I understand what you are saying. You are going from your TVs audio jack into an amplifier TEAC AG-V8050 and then into the Sennheiser T1250 unit? This is done to amplify the sound so your wife can hear the TV via Infared into headphones I am guessing. The connections would have to be as follows. TV RCA jack (Installed by someone to TV audio Output section, most likely the speaker) to the Amplifier TEAC AG-V8050 via RCA cable then from the Amplifier via RCA cable to the Sennheiser TI 250 IR Transmitter. The transmitter then takes the audio input and turns it into a digital signal which is transmitted via IR to headphones which your wife is using. First of all the amp TEAC AG-V8050 is not needed. what happend here is the person doing the installation took sound off of a preamp to avoid having to deal with the TV volume control. This works but it makes matters harder. So here is how you troubleshoot this problem: 1) Disconnect the amplifier and plug the RCA jack of the TV into the RCA jack of a set of amplified Mono headphones. (This is to determine if sound is coming from the TV) If not the problem is in the TV audio section and you will need to take it to a TV repair shop. 2) If audio is coming through the headset the trouble is in the amp or the sennhiser unit. To test the sennhiser unit: plug the sennhiser into the audio out of a VCR and listen in the headphones for sound. If you have sound, the sennheiser is good and the problem may be in the amplifier, but if you do not have sound the the sennheiser is bad. 3)Connect the audio out of the VCR into the audio in of the amplifier and plug the output of the amplifier into the sennheiser which tested good with just the VCR alone. If no sound is present then the amp is your culprit. Once you find out which component is the problem, I would suggest finding a rapair shop here on FitYa to repair your unit or having an electronics technician come to you to fix the bad component. This should help, Thank you, Shuttle83
