it could be a cooling fan or power supply problem or a switch on the saftey inter;lock on the lamp door
it will require some trouble shooting if your having problems finding some one in your area contact sony for a referal to a servicer in your area
No,check for loose FBT-flyback tranformer connections a big black block of a plastic with a wire to a board section call highvoltage deflction board area.Useally the FBT is dead,require replacing and trouble shoot the deflection board area for other dead parts.Get quote prices from shops.Must hire a tv Tech. must do alot trouble shooting and replacing components.
The buzzing sound you hear is typically the FBT shorting out when you turn the TV on. If you open the back panel and watch the FBT as you try to turn on the TV you can see it shorting out. It will be obvious.
Unless you are skilled at trouble shooting power supplies , you will be better off getting a skilled repair center to repair yourset. If its repairable I have seen surges from lightning strikes make the set no longer cost effective to repair.
The clicking is the power on relay closing and opening. This happens because the TV has several built in safety systems that will detect and over voltage and over current load situation.The power supply starts up for an instant, senses and overload of either or both kinds and then the safety switches trigger a cutoff. When this happens the power supply will not start up again because another circuit called a latch keeps it disabled. By unplugging the AC cord and trying to start it again releases the latch until the failure triggers it again.
On these TVs the power supply is rarely the cause of the shutdown. Something further down inside the TV has failed. Replacing just the power supply will not fix the problem. The most common reason there would be an overload would be in the high voltage circuit that lights up the 3 CRTs, next would be the coils around the CRTs that bend the beams to make the picture. This is normal circuit aging and wearing out. Unless you are very skilled with trouble shooting TVs I would recommend having a service center look at it. An authorized JVC shop would be your best choice because they will have access to the manuals and bulletins and have probably had other similar JVC units thru their shops.
You can check the board where the components are mounted and resolder any that look bad. a brief power outages may cause the TV to turn off on its own. If you are using a surge protector, try connecting the set directly to the wall outlet.
In your case it could caused by a blown fuse, a leaky diodes or a bad solder joint at the horizontal drive transformer.
all can be replaced at a local electronic or hardware store and they're easy to replace
If this does not correct the problem, you may need to have your TV serviced.
