Question about JVC AV-48WP30 48" Rear Projection Television

1 Answer

Sparking Sounds and the picture jumps momentarily.

Every once in a while I hear a spark from behind the Back perforated panel like a capaciter discharging and my picture will flash. The frequencies of the spark vary, and it doesnot happen all the time. I looked in thru the perferations on the back panel and notices a spark when it discharges. I live on a island in the middle of the Pacific Ocean and there are no repairmen here. Help Lost in Paradise.

You need to remove the back and observe where the spark is coming from while the set is on. Dimming the lights may help you. Sometimes you can see a blue glare accompanied by an ozone smell. You might even hear a sound such as a slow air leak in a tire. The most likely area is around the high voltage transformer or the picture tube anode. The transformer has the thick red wire or wires coming out of the top. Also follow the three red wires to the picture tube anode( the place where the red wire plugs into the tube) Use your senses, listen smell , and look for any blue glare or arcing to the metal frame. If you find the leak near or on the transformer use 100% silicone rubber to patch. Allow at least 12 hours to cure. If the arcing is coming from the picture tube contact me for detailed instructions. You must act promptly and find the source of the arcing before you have a dead set. In short, spark + flash = crash. Good luck

That is going to be an ignition coil. That is what produces spark. But it could be the knock sensor or the cam sensor also. If they do not give the coil the signal to fire, then the coil will not spark.

You are quite correct in thinking that it is the motor brushes that are worn.
You need to remove the motor and replace the brushes.
This will solve your problem.

3 of the 4 burners are continously sparking while turned off.

1997 buick skylark wont start


Does it crank and not start or not even crank. You could have a bad starter. I would test the battery first. When it won't start try to jump start it. If it jump starts it's probably the battery. If it won't jump start it's probably the starter.
