High pich whine from CT-36D32 36" TV

CT-36D32 36" TV This is my T.V. I moved it, watched the super bowl and moved it back. One city block in an Astro with good suspension and no bumps. I took it easy. I pressed power on the remote and got a high pitch whining tone constant from the lower back left of the tv. No degauss no screen flicker no Sound nothing but That noise. I can unplug it and the releay drops out and the noise goes away. Plug it in, I hear the relay engage then a halfway degauss. Not even a flicker in the screen in the dark of the night... How wird is this???? jdosk@bellsouth.net

    I have the same problem with mine. I called sears service and they told me that it would cost 600 to 700 to fix, I then had to pay a 100.00 service call. I asked what caused this and the tech said that dust over the board prevented it from cooling down causing the problem. I have had this tv for just 6 years and it sure should have lasted longer that this, heck I still have tvs 20 + years old that still work. If any one can help with this repair please let me know. I refuse to just toss it into the trash can

    I have narrowed the noise down to the open coil transformer looking thing that sits virtical to the front of the board bang in the middle. Front being toward the manual switches. This is the only coil that sits upright and the coils are wraped horizontaly. I assume that this is some sort of step up transformer. I sure don't know what is causing the osolations like that. ???? The Hi voltage Trasistor is not geting warm that is in close proximity of it.

    Got the meter, Don't really know whitch is the fly back. I do know what transformer is osolating in the HOT part of the main board. What could be shorted? I have found new board and snap on part that is part of the HOT bout 400 bucks. Would that fixit?

    What would it look like? I have soldered all the joints that looked bad. From what I read you are saying That the transitor is bad? not sure what to snach off the board and test. I know by the well marking of the board, which is the HOT area of the board... I do see a large Hi voltage looking darlington that has 4 legs on it. Could that be it...?

Bad solder connects in horiz driver circuit lead to shorted horiz output xistor....do.not try generic....won't hold...........T.

Jdosk-the high pitch noise you hear is generally from the horizontal output being shorted,the horizontal output is usually near the flyback transformer,get a digital multimeter to checkthis part.Let me know I'll try to help. cooltek Feb.16/08

I was watching the super bowl and my JVC projection screen shut off, when I turned it back on the blue power light and the red light above it flashed continually... I pulled out the lamp and its blown.. if...


Hi.
Yes, if you pulled the projection lamp and it is burnt-out, then yes. This should indeed fix your problem.
I'm sorry that it had to happen to you in the middle of the Super Bowl, it's turning into quite a good game.
Right now as I post this..it is GB 28...PITT 25 3:00 to go 3rd quarter...GB is 1st and goal from 8 uard line.

I hope you can get it to work again, but unless you have an electronics store that is A within a couple of blocks of you, and B OPEN...then you won't have it going again before the end of the game.

The TV is making a very high pitched noise. The longer it is on the louder it gets.


Easy repair with some Super glue.Must take the tv back cover out.The FBT-the big block of plastic with a red wire with a cap hook to a CRT(tv tube).It have a high voltage gap going through a "3 inches paper clip steel bar on a FBT the big black plastic block.Put some super glue on that "3 inches paper clip steel bar on that big black plastic block.Should stop the high voltages gaps through that "3 inches paper clip steel bar causing a high pitched noises.

The power surge has caused a failure of an internal component. If it is making this noise it is possible the line output transistor has failed. I would advise calling a service repair centre & have someone there take alook at it. All being well this may be the only problem. Power surges can sometimes cause other faults.

The high pitched sound is probably comming from the power supply, possibly due to its trying to drive voltage into a shorted component in the high voltage deflection circuits. You may be lookng at about a $250 repair. If it has been used a lot and its picture quality didn't knock your socks off, I would replace it with a HDTV set. A 37 inch LCD from Toshiba might be a good place to start and should do nicely for you.
