Bad electric shorting sound

check wiring-stat-element with a multi meter --ohms and short test do not plug back in until testing system

I would unplug everything from the back of the system, clean the connections with a brush and rubbing alcohol, then plug everything back in. Turn it on and see if you get the same problem. If so then try unplugging the cameras and see if the noise stops. If the noise stops then one at a time I would plug the cameras in watching to see if you get a picture and/or sound. You may have a bad camera that is sending a short to the system that sends the system in to a protection mode.

It could be anything, sounds like either a power supply issue or a short circuit, dont try and turn this back on as you will only do more damage, unfortunately the only solution is a professional repair and that may not even do it, smeeling burning usually means something died inside, so it wont be cheap. sorry to be the bearer of bad news

looks like the color wheel its bad in the set,color wheel its not spining at its proper speed( one of the segments may be broken)
thats the vibration you are hearing.. and the set its trying to turn on..until you replace the wheel you will be able to watch tv again.

if you are not afraid to get in to the back of tv, the chassie has 4 different fans,you can unplug the tv remove all of the screws on the back,and remove the lamp door,there are about 5 plugs on the top of the chassie that plugs in the tv,donot unplug these plugs ,you can pull the chassie out of tv until you run out of wire on the plugs,then plug the tv in,turn the tv on, and you might hear the fan thats bad. If you are not comfortable with this call a repair man,the fans are not that expensive,and are pretty easy to change.i can guide you thru the replacement process if you need my help.

My guess is that the belt is going bad. It could also be a bad bearing...the noise is generally metallic. Also...a bad belt tensioner comes to mind.

Bad IHVT ( flyback transformer)--need complete service
number off back for part #-----------Let me know...T.

It means that the TV set has a short in it somewhere. The sound you hear is the power supply trying to start up and shutting down. Most likely the Horizontal output transistor shorted because of a bd high voltge flyback transformer went bad. Common problem for these types of sets. Good Luck

You have a short somewhere in your set. Most likely the horizontal output transistor.The sound that you are hearing is the power supply being overloaded. If the horizontal output is shorted, you probably have a bad flyback (high voltage) transformer. You need to have it checked out by service tech also ask for an estimate. Stargazer
