Question about Audio & Video Receivers
Does anyone have the remote control codes for a Parasound TDQ-150 AM/FM tuner? I bought one used without a remote control and I want to see if I can get an universal one to work.
SOURCE: No sound
Try the other inputs and see if you have the same problem with them. That will let you know if the problem is the tuner or if it is something else.
Since your receiver does not shut off after a few seconds it should not have an amplifier problem. If it did shut off quickly it is know as the protect mode and normally indicates that you have a blown channel, not always, but normally it is that.
If you get no audio from any function, you may have a digital board problem which is a very difficult problem to isolate and repair.
A couple of things you can do to make sure it is not something like a wrong setting is to make sure that the "Tape Monitor" switch has not been pressed accidentally. If the "Tape Monitor" is engaged it wil appear that everything is normal with the display and functions, but you get no audio from anything unless you are recording on a tape. This can happen even with no tape deck connected to the unit. Study the display closely and see if "monitor" or "tape monitor" is lit up anywhere in the display, or if you have an led on the tape monitor or monitor switch, that led could also be lit up red. If you turn the volume up all the way, do you get a very faint amount of audio? If so, you probably do have the tape monitor engaged.
Also check that the speakers are activated. If you have only one set of front speakers you want to make sure that only those speakers are activated. You will have a button for speakers "A" and "B". Make sure that only speakers "A" are turned on. Some receivers will not have any output if you have both "A" and "B" turned on but only have speakers connected to the "A" speakers.
If your receiver has a button for the headphones make sure that is not engaged as well. Many receivers will not have output to the speakers if the headphones are turned on. Or if you have headphones connected, try unplugging them.
Those the only user type of things that you can do unless you have some good electronics troubleshooting skills and the proper tools. So if you have checked those things and still have no audio you need to take it in for service.
Here is a link that you can get your owners manual from online for free. It is always a good idea to study the owners manual to make sure you have everything connected properly and have the settings correct as well. Just go to this link and put in your model number exactly as it is on the front of the receiver to make sure you get the right manual. If you put in the wrong model number you will get no results when you search for it.
I hopes this helps, and if so a "FixYa" rating would be appreciated.

SOURCE: reset channels??
Here are the links for the manual. I've lost my remote as well. I can't get my unit to recognize the digital audio input (optical). Very frusturating.

Check your antenna connections. Make sure your FM antenna is hooked up to the FM antenna terminal or jack on your Sherwood receiver. If you have the antenna hooked through the coaxial cable, check your coaxial cable with an ohmmeter for continuity. You can buy a volt-ohm meter as little as $12. Usually bad connection occur between coaxial cable and the the coax cable connectors. If that doesn't solve the problem, then there may be something wrong with your tuner card inside of your Sherwood receiver.
If you receivers display does not change channels or frequencies or AM or FM mode, when you try to change the channel or frequencies, or AM or FM mode, there may be something wrong with the front board of your receiver.
If there is something internally wrong your Sherwood receiver, you need to take it to a qualified technician that can fix it. Do not try to repair it yourself. If you don't know what you're doing, you can do far more damage to that Sherwood receiver to the point that would be very costly to repair.
Before you take your Sherwood receiver to a technician, try to unplug the receiver, and leave it unplugged for several minutes, and then plug it back in. If that doesn't solve the problem, then you need to take your Sherwood to a qualified technician.

Your unit's micro IC, is in need of a reset.Un-plug the unit and locate the semi large yellow capactor on the main board. (r-h side facing front) Now flip the unit over and look thru the vent holes in that same area and locate the two solder pins. Short them out with a thin metal object, like a straightened out paper clip or wire, and turn it over (just discharge the cap and remove your wire) this will default all settings and restore normal operation.

if the tuner has lost its ability to remember stations, it is due to the low backup battery. Replace the old one by a new 3V lithium battery. Can be the same as used in PC mainboards. If the old battery is fixed with welded metal strips, cut them near the battery. They cannot be welded again to a new battery. Bend the strips close together, so that the battery is hold tight when iserted between the strips. Observe the correct polarisation of the battery, must be the same as with the old one.
