About two minutes after the TV is turned on, it starts making a whirring noise. The longer the TV is on, the louder the whirring noise gets. Please help...the noise is making me crazy!

The noise you hear must be from its back-light inverter board. The ferrite core in the inverter transformer may make a high whistling noise and will be annoying. Contact any technician. It can be stopped by gluing. But is a skilled work.

    Thank you for responding to my question. It's an older tv so probably not worth spending a lot of money on it for repair. I was hoping it would be something simple I could fix myself!

SOURCE: tv making loud buzzing noise

A common cause are failure of decopling capacitors in the audio section, and or the circuit board power distribution that feeds the audio board. Most of the capacitors are surface mount components. The standard fix is to start by changing the circuit boards that have the defective parts.

If the set is under warranty, call for warranty service. Out of warranty service is expensive for these TV sets.

The TV should be under warranty. Send back. Sounds like the panel is faulty (half the value of the set).

Does not drown out background noise, only makes it louder

If you have just bought these, take them or send them back.

Samsung HLS5086WX/XAA made popping noise and shut off, then made whirring noise.

When my TV did this in the past it ended up being the color wheel. I had someone replace it and it worked fine. I asked it if had to be calibrated after it is installed and he said no. Also make sure the door switch is pushed down when you install the back bulb door. Sometimes this switch can go bad as well.

I have a magnavox 37mf331d/37 that has developed a high pitched whine.the longer the tv is on the louder the whine.the tv is 5-6 yrs old

It's likely a capacitor associated with the power supply having gone bad.
It's obviously beyond your expertise to repair it yourself.
Find a trustworthy repair shop and take it there.

Toshiba 52HM95 whirring noise

Color wheel. Not replacable on this set. Removing light engine and having rebuilt is only solution. Part no longer available.

Louder whirring noise when turning on computer

trumpjd,
Usually on startup the fans work a little harder then slow down. On newer computers they still have noticable fan noise. Most of what ou hear while the machine is running after start up is the power supply fan. When it starts to go bad you'll hear it all the time.

If that is whats wrong with you, you will need asoldering tool, I bought my as a kit at radio shack for $20.00 and plusthe $36.00 for the kit, and a lot of patience, my TV is well andrunning now, it was better than the $600.00 estimate I got from a localrepair shop.

Whirring noise, camera won't turn off, blank screen

The problem isn't fixed but I found out on the Nikon website that it may be due to an electronic component failure. I downloaded a form from Nikon to send it back in to them for free repair. I'll keep you on my list for future problems. Thanks.

Loud whirring. Not the fan.

The fan noise is normal on this set. The lamps are cooled via this method. Your users manual explains this issue..and it is the fan as you can see it slows down after the tv is switched off..
