A problem has been detected in the final stage of the output amplifier. Remove the speaker wires and try again. If the problem persists, it is inside the amp. The most common cause of this is the output transistors. Expect a parts cost of between $15-$25 plus the local labor rate for the repair.

    You will need to search the web for service manuals, but I don't believe that they are available. Techwood systems use rather standard designs and are relatively easy to repair for anyone that has done a lot of audio repair. If you feel you would like to try it, look for the large transistors that are mounted to the heatsink and remove them (marking the heatsink so you know where to put them back). With the unit turned on, it should not display protect anymore. Using a volt meter, measure the voltage on each of the 3 pads for each transistor. You should read the following: (0.0V, +/-0.6V, and +/- B). The B here will be over 24V and probably in the range of 50 or more. If these readings are as stated, replace the transistors and the unit will be fixed.

    Good luck.

This receiver has 100 watts per channel. If b side speakers aren't working you may have them hooked up wrong. Try connecting the B speakers to A terminals to make sure speakers are functioning. Please see the user manual below for wiring diagrams.

How can I listen to audio from Techwood TV/DVD player through home stereo? I have connected a red&white stereo lead & selected aux on my stereo, but sound still just comes out from the TV. Any help is


Make sure that you are using the Audio Out ports (not one of the audio in). Next go into the menu. Select the Audio setup option and see if there is a line for enabling the external speakers. (Often this corresponds to turning off the internal speakers but not always.)

I hope this helps. I'm not familiar with the specs of Techwood TV models. Some TVs only have an headphone/earphone (3.5 mm) jack as their audio out. In that case, you'll need an adapter to convert the RCA audio to the headphone jack.

My stereo sysytem is a mini stereo: serial number 10200055. It currently says "protect", what is this and how do we return our system to normal operations?


Hi there,

When the word PROTECT appears on this display, this means the unit has detected a critical fault which could potentially cause harm to your stereo system.

The most common cause is a short circuit somewhere - something even as simple as loose speaker wiring could cause a short, triggering the Protect message.

You will need to determine if there is a possible short somewhere, so I recommend you start by firstly turning power OFF, disconnecting all speaker wires, then turn unit back ON.

Operate the stereo (without speakers) and turn volume up:
  • If Protect message appears when turning volume up, then stereo unit itself has an internal fault
  • If no Protect message appears, then suspect the speakers may be causing the issue.
  • Reduce volume and turn unit OFF
Re-connect speakers (ensure the connections are secure), turn unit ON:
  • If turning volume up triggers the Protect message again, there is an issue with the speakers or connections

Hope this helps.....

Can I connect a Computer to a Techwood DDR 94 AV Digital Surround Receiver so that I can listen to radio stations online?


Yes. You can. First, you need a cable that has a stereo pin called stereo jack (the type that has on ear phones/head phones) on one end and component cable terminals (the type that comes with video/ audio left and right) on the other end. To further explain, these terminals come in yellow red and white colors. You only need the red and white ones. This is available at electronic stores. Otherwise a person who service electronic equipments can easily make one. Basically, this cable will have a stereo jack (small one) on one end and split into 2 cables with the red and white terminals. Once you have this cable, connect the stereo jack to the ear phone socket of your computer and connect the other end to the audio input of your Techwood receiver. You can select anyone (CD, DVD or TV). These inputs are right above the speaker wire connections. Be careful to connect to the socket that say "in" . Now, let us assume you have connected to the CD, select your source as CD on your techwood receiver. Play music on your computer and you should be able to hear the output through your Techwood receiver. Good luck
