I have replaced 4 of the caps where around where the sound was coming from and the noise has stopped, now the TV is trying to come up but when it tries to power the CRT the same noise was down before goes through the big wire coming from the flyback to the screen. It seems like the screen charges and descharges right away back through the big wire on the flyback. I am just wondering if it is the flyback itself or the CRT is not holding charge somehow. Any help please.

Sounds like a transformer or choke that has loose windings and they are resonating, you can pull the back and put small amounts of silicone on those components or replace the power board

You have some leaky caps in the sound section of your TV or a bad audio output chip.

The Power/Timer light SHOULD stay green on a normal working TV. It sounds like the main board is either defective or has a connection problem to ??? (power supply, etc). All fans should be turning (a hint of missing power). Check ALL cables...be thorough.

I have this TV. My father in law tried to turn it on one day and it started making a clicking sound and never came on. So he went out and bought a new tv and gave it to me. It came on when I brought it home and worked for a couple weeks. Then just the other day it stopped working. When you hit the power button the light around it blinks four times and then you here a clicking sound. TV does not come on. Took the back panel off and I don't see any damaged caps or fuses.

it is a power supply issue. options 1- replace the power supply
2- this unit has an issue with 4 capsitors on the power supply which sit side by side and are about 10 volt each replace them with standard 16v caps.

Check your power supply board for some bad caps (capacitors) on the board. They will look bulged on the top an may be a little leaky (brownish stain). A bad cap can sometimes produce a harmonic, causing issue's with the sound. Also look at the signal board (where all the inputs are), for bad caps. I have come across this on a lcd tv!! Good luck, hope this is helpful!

You can tell to some extent what it may be by listening carefully and trying to identify the location. If you, remove the back cover of the set; stay away from danger, just listen to where it seems like the sound is coming from. If it is coming from inside the high voltage cage it is the flyback. If coming from around the main power transformer it is one of the power supply parts.

most high pitch noise comes from the anode conection on the picture tube thats connected to the flyback anode cap thats mean there is a high voltage leak,to stop the noise you can discharge the high voltage take off the cap and clean with alcohol.if the noise continue.you will have to put some red or clear silicone both the cap and tube stick together leave to dry for about 2 to 4 hrs.this will eliminate the leaking.good luck.

The anode cap on the back of the tv tube is leaking the high voltage be careful as going into the back of a tv it store very high voltage and could be fatal.the solution to problem get a tube of clear or red silicone discharge the high from the tube,you do this by getting a alligator clip with wire attach clip to a ground wire on the back of the tube attached the other end of the wire to screw driver gently push it under the Anode cap you will hear a popping sound with i little sparks. remove the cap from off the tube get some alcohol wipe the dirt away apply the silicone around the anode and the anode cap place in on back and leave it to dry and cure for about 7 hrs close up back and turn on your tv and all the popping sound is gone.good luck.but if it is the wire for the anode cap that comes from the flyback is the one leaking change the flyback.again good luck.contact me on fixya.com or email me at [email protected]

solder all around the flyback area if this not resolve the problem replace the flyback
