Hello altoboy,

This sounds like either a problem with the IHVT and or the Horizontal Output Transistor. Open the set and check to see if the sound is coming from a big black partially circular component with at least two wires coming from it and also check the box to which one of the wires is going to and three wires are coming out. This is your High Voltage trippler. Now if you do not have a background in Electronics, I would suggest that you take this to a qualified TV repair shop to have it worked on.

I hope this helps,

Thank you,

It's obvious that the power supply failed. The most common parts in a power supply are a thermistor or a voltage rectifier, possibly even a voltage regulator. diodes or resistors can act as fuses too. A ringing sound can come from a fixed coil that isn't kept still with enough epoxy. Hope this helps.

Panasonic PT-56LCX66 buzzing noise when i push power


I'm going to take a guess and say that the buzzing noise and burning smell was either a transformer or a blown capacitor (more likely). It's likely that your old lamp was still good and there is a problem at the circuit level.

If you or someone you know is comfortable with electronics, you may want to open it up and take a look. If there is a blown capacitor it will be obvious. Take a look at badcaps.net or Youtube for help on identifying them.

If you don't feel comfortable working on the inside of a TV it's probably time to get a new one. Repairs will not be cheap and they won't be worth it.

Have just bought an LG37LD450. Buzzing noise coming from the components at the back of the TV. Annoying. Otherwise TV perfect. Definitely not sound problems because buzzing noise still there when on Mute....


Had this problem as well. Ran through a laundry list of possible solutions. Finally found that the key is to increase the backlight (Access via [Menu] [Picture] ) to 100% and the noise goes away. If this is bad for the life of the backlight, just pray the backlight burns out inside year 1 while the warranty is still valid!

Set was on and made a loud pop noise and the picture went off. the red light was flashing and no picture. then it made a strange buzzing type of sound a few times. turned off for a couple mins and then...


It sounds like your screen inverter has just gone >bang< unfortunately.
Most screens inside use 2 main circuit boards, and you are most likely going to have to change one of them.
It's possible also for it to have been just the backlight bulb making the loud pop noise too. The inverter may have given out too much power and blown the bulb (a lot like you hear when a house bulb goes bang).

If you can't actually hear any TV sounds (normal sounds like music, voices etc. when they should be there), then it means the problem is more serious, and would need a specialist repair place to check out the electrical circuit inside.

Buzzing Noise and TV picture is yellow


Andy, I'm thinking the buzz is from the deflection coil (yoke) on the neck of the tube or the power supply. Probably not the high voltage as you can hear the "buzz". If it's really that annoying, you can take a length of rubber tubing (no metal) and listen to the buzz coming from the chassis kind of like a stethoscope. STAY AWAY FROM THE HIGH VOLTAGE, please. The yellow picture sounds like a blue chroma failure. A tube can be rejuvinated if need be but that's a job for a pro. Hope this helps.
