JVC AV-21QMG3 Random 'Pop' sound

I have a Multi System (Dual Voltage) TV (Mo No. AV-21QMG3 i brought with me back from Europe. Now, using 120V (when i used to use 240V), it works but i see a light on inside the back of the tv and it makes a random 'pop' sound. I doubt it is supposed to do this - what is wrong? Can I fix?

Problem with JVC CRT TV (slim) with screen to have red color at the lower left (facing the TV) corner and a green color on the upper right corner of the screen. Sometimes while watching TV shows, the upper...

There is strong magnetic field around the TV. This may be due to the tower speakers or any portable radio kept close by.

Re orient the TV try switching OFF / ON at the intervals of 30 minutes. The built in auto de-gauser will correct the problem. In cable TV program if the picture is OK, nothing wrong in the TV.

Check with a different CD.

This TV has a European RF (antenna) connector called the Belling-Lee type. There's a Wikipedia page about it if you want more information. While this set will tune American TV broadcasting and cable, it was made for the European market. The manual (available here) even refers to this as a "colour" TV. If you're using this TV here in the US, Radio Shack carries an adapter so you can connect a standard F-connector.

Hope this helps. Thanks for using Fixya!

TV made a loud pop


sounds like a popped power capacitor, its going to have to go to the shop most likely around 100.00 repair. taking the back off yearly and airdusting them helps, especially if you have a smoker in the house. caution high voltage present even when off, the heavy single red wire going to the tube is high voltage be careful.

Your tv might not support that option there might be an antenna for basic channels on top of your tv but what you can do is get video + sound cables(red,yellow,white) and connect them through this way.

No picture but sound is perfect

Sounds like the video output has a problem. Maybe missing the 200 volts from the High voltage transformer. The vertical circuit may have an issue. Either way it's hard to diagnose without looking at it. If you need a technician contact JVC online at: Good Luck
