Audio noise on cold start

When I first turn on the TV (JVC AV-32750), there is a terrible noise coming from the speakers for about 20-30 seconds before it starts to subside. Once warmed up, there is no noise. I can even turn the TV off and then back on without problem. It sounds like electrical interference, but I don?t think that is the problem since it has worked for years in the same location. I have the satellite receiver audio hooked up the audio receiver for sound so I have the speakers turned off and the volume turned down to zero. Thanks in advance.

just look in the section for closed captions----the box is the "text" feature and just needs to be turned off; if you did it without a remote it can be undone the same way.

How to find JVC AV27320 headphone jack? I've plugged into the avs(red & white) in the front panel as well as the extra ones in the back. Altho - I CAN hear the sound thru the headphones, The external...

This model doesn't have a headphone jack. The only JVC TV in the series that does is the model AV-20D202. For the JVC AV-2732, use the RCA audio out jacks with an RCA to 3.5 mm adapter to connect to the headphones. The front audio jacks are audio in (for the audio from a video camera for example).

When you use any external speakers or headphones through the audio out jacks, make sure to turn off the TV speakers. Press Menu and navigate down to TV Speakers (up/down arrows). Then use the right/left arrows to select Off and then Exit the menu. Make sure you scroll the TV volume before doing this. Note: if your headphones do not have a volume control they are a bad choice for this type of audio output.

You can find the manual for the TV here: http://books.jvc.com/booklist.asp?Model=AV-27230 .

I wish that I had better news for you.

It is worth getting an estimate. From the symptom you explained, it looks like the horizontal output transistor became defective.

TV wont power on, clicking noise and flashing standby led

Sounds pretty bad to me, I had a computer monitor that did a similar thing when plugged in after blowing, it's not a good thing. I didn't even bother to mess with it. You may have to replace the whole power board or at least have a whole handful of pieces to re-solder. It most likely isn't worth it unless your other tv's are under 30" and you don't have a lot of money ;)

Resolder the vertical deflection output IC421. It is located about three inches to the left of the flyback transformer which is the part with the red cable going to the picture tube.

stairmaster 4000 won't turn on. It has a reset box attached. The cord to an outlet runs out from that box. I press in the long needle like red plastic button. The red light on the rest box turns on (red light), but only stays on for a minute, then shuts off. No power goes to the machine even for that one minute. I would guess a fuse was blown, but I am just guessing... and I do not know where this fuse would be, even if it had one.
