Sounds like your high voltage section, or your main power supply is shot. DO NOT OPEN THE BACK OF YOUR TV.

The chassis of the TV ( any metal inside the plastic outer shell ) is Electrically HOT ! The High voltage section has upwards of 30,000 ( thirty thousand ) volts running to the picture tube...so DON'T TOUCH ANYTHING.

THe Humming noise is the TV Drawing a lot of current and trying to work. Don't continue to let it try or it will be an even more expensive fix....pull the plug !!

WHAT YOU SAW:

  • "The picture could condense to very thin and then go back to orginal size"......this means that the vertical high voltage section was collapsing (the high voltage for this part of the picture has failed ) and coming back ( normal picture )........this means that some part in the HV section was on its last legs. Now it has no legs.
Best thing you could do is take it to a shop. I have a 32" JVC of the same era and love it. It has given me no problems at all, and even though the price of a new "Tube" TV is extremely low, the picture quality isnt anywhere near as good as your old JVC. Personally, I would at least get an estimate to repair. Good luck....Rob

The TV will bring to turn on but then it sounds like it loses power and makes a high pitch noise and powers off, no picture ever comes on the TV, the screen stays black the whole time. The TV is a RCA...


it could one of two things. The power supply is failing which is most common. Or the picture tube is gone. Both would most likely cost you more to fix than the TV is worth. Call around and get a few quotes. Good luck

I'm experencings a buzzing noise coming from the speaker when I turn on the tv....How can I get rid of this noise?


Give this a shot, it should fix the hum issue:

1. Turn tv on
2. Input mode should be tv
3. Turn volume to zero
4. With remote enter 9 8 7 6
5. A menu will appear on left side
6. Arrow down to backlight and with right arrow key move number from 81 to 83, press menu button twice,
7. Turn up volume and listen if hum is gone.

Let me know if this works.

humming is due to main filter capacitor have gone dry or defective. repace it humming will go. picture cut is due to less voltage going to vertical stage.coming froh eht(hor stage.) as main filter will cause main power supply to be low which will cause low voltage to hor.stage.

Picture went out and all the tv does is make a buzzing sound


The horizontal output transistor drives a transformer that gives you the high voltage to light up the picture tube,either the transistor or the transformer have gone bad,sometimes both have to be replaced and sometimes the transistor fails for no reason by itself.Be safe and call for help if you are not familiar with tv service.
