C32A26 crt TV; No audio or video

I removed the back housing, disconnected the speakers, and slid the circuitboard out in an attempt to pinpoint a faint clicking noise the tv made when plugged in. The 120vAC hot side connects to the board, to what I think is called a transformer (tx?), then to a 12vDC black box gizmo. the clicking noise is eminating from the tx. Does this indicate that it is bad, or is there some way to test it with a VOM? Its been well over twenty years since ive had any electronics training, and technology has changed alot, but 120vAC still bites just like it used to, lol. any advise or info about how to proceed is much appreciated. Thanks.

Mmm this is tricky - there is no normal transformer power supply in a tv. They usually just rectify the supply and regulate it for the circuits, and use voltage doublers and a transformer to get the EHT. Be carful the voltages can be 20,000volts! Check all the capacitors. The EHT flyback transformer can arc and present a clicking sound. Make sure everything is clean.

I have no volume on my television. It is coming up as 'speakers off'. This only affects television programmes. The sound is still on for games and dvds. I cannot get the sound back on.

It could be that you have not properly connected the cables to audio and video jacks on the TV. Try disconnecting all and reconnect to respective jacks on the TV. GL

I want to connect external speakers to tv

If this unit has audio output jacks then these would be connected through an amplifier to provide your external speakers. Caution: Do not open the tv and connect additional speakers to installed speakers because you'll blow the small audio amp in the tv. I have seen this attempted many times

First it turned green for a while and then turned it off, and I can turn it in again.

Sorry, you have described the classic shorted CRT (picture tube) for this unit. Another problem could be the CRT socket. Less expensive to repair. Both would require a trained TV technician to repair.

No sound coming out of my Onkyo SKW-200 subwoofer

A subwoofer is just really a mono amp for the signal. As with all amps if you touch the audio section/parts with a small screwdriver, you should hear a buzz from the speaker. (Follow the audio wires to be certain you are on the audio section). This can be used for testing the amp section. If you get no buzz or noise (anywhere) at all then it's power supply could be playing up. If you have a multimeter you can test it looking to see if it is getting power. Allways suspect any part that is on a heatsink. Before removing any suspect you can put the part numbers into Google to see if you can get them and it will give you a clue to cost.
PS don't short any parts when you touch with a screwdriver, and don't put it on the power parts.

Aquos LC-32D43U, no audio

My suggestion would be to bypass all of your video components whatever you have be it a vcr, dvd player,whatever and just hookup the tv direct to whomever you receive your cable tv from. Because it was working before you moved it and disconnected the external audio source. Remember if your using HDMI cables they are your audio and video together and you don't need to hookup anything else from that device to the tv. Just FYI. Good luck.
