TV won't turn on, makes high-pitched clicking noise

Hello, My Philips/Magnavox 27" (I know, this is listed a 19", but I couldn't find my specific model and this is the closest one) TV, around 7 years old, suddenly stopped working. My wife was watching it around 5.00 pm, and around 7.00 pm we noticed it was making a soft, high-pitched, repeating noise, not quite like clicking but that's the best word I can think of to describe it. At first I thought it was a DVD stuck on a track, because it kind of sounds like the sound the laser head makes when it moves around a little -- this high-pitched squeak/click. It makes the sound in short increments, probably 4 or 5 "clicks" per second. The sound only stops when we unplug the TV from wall outlet. I tried unplugging the audio/video cables from the DVD player, and the coax from the rabbit ears, but those don't seem to make a difference. I notice the sound the loudest from the back of the TV, as best as I can tell, right underneath the back of the CRT (I'm not too familiar with the terminology; the "apex" of the cone-like shape that makes the TV display images, that is, the part in the back). This is more than likely unrelated, but in between the TV working and noticing that it wasn't, my 1-year-old son threw the TV remote. He was in a different room when it happened, though, and I just can't see how that would make the TV itself stop working. Thought I'd mention it, though. And I did try fiddling with the remote, pressing the "TV" button, etc, but with no luck. I would love for this to be an excuse to ditch the CRT TV and pick up a flat screen of some sort. But if it's a cheap fix, then I should do that... Thanks in advance. Dru

Re: TV won't turn on, makes high-pitched clicking noise

Its a real good chance that the HOT (horizontal output tranistor) transistor is shorted if so the flyback trasformer may be bad also. the transformer will make a tick tick sound if it is trying to start.

Re: TV won't turn on, makes high-pitched clicking noise

This is a known problem. Do a search at amazon and see over 150 complaints. You'll also find instructions and photos how to change the fuse yourself. I did it myself. Fuses cost like $0.79 each. We have had to change fuses twice, so it's not a permanent fix. The original fuse lasted less than a year. The first replacement fuse I installed lasted two years.

My sansui tv makes a loud high pitch noise. I have had it 3 years, it is a a riging noise, and hard to hear the tv shows. what do i do?

ever since for ever, ive always heard a loudish high pitched ring from analog tv's. e.g. i would know a tv was on in another room even if it was muted. ive told other people about it but they dont seem to hear what i hear. so im gonna geuss either

a. analog tv's all make that noise to a verying degree but most people just dont notice it or subconciously cancle it out as normal.

b. its a kind of hyper sensitivity to high pitched noise, in essence, tinitus.

on a final note, its not medical as i always pass my hearing tests. but to answer your question, either buy a digital tv or turn up the volume.

My Magnavox plasma screen tv, model number: 42MF237S/37 makes a clicking sound when I try to turn it on. No sounds, no picture, just the clicking noise. Things I have tried so far: 1) Turning the TV off...

You either have a cold solder joint in your horizontal deflection circuits or your or in your horizontal output circuit. please be careful due to the fly-back transformer still holds power even unplugged until you discharge it.( ground it out). Hope this helps.

Tv runs for about 4 hours and shuts off.

the tube is going out better off getting a new one since the cost to repair it would not be worth it but if even tho it may work after doing all of that the reason it stay on is that the switching of the channels is doing something to the control board and allowing it not to short and turn off

27 inch tube tv won't stay on

You have a problem is in your horizontal section which also is part of your power supply. The high pitched whine is from the Intergrated High voltage transformer (also called the flyback transformer). This sound occurs when the freuency of the transformer changes and or the voltage gets too high. The click occurs as a result of the drawing of excessive current by the HOT Horizontal output transistor. This is repairable, but requires the correct equipment and a schematic.
