Question about JVC AV-35750 35" TV
Makes a buzzing humming type noise with no volume when I first turn it on after a few minutes it pops and the sound comes on but now it has started making the noise randomly during a show when it goes to a comercial or when it switches scenes. Only does it for a second or two but starting to do it more frequently. extremely annoying picture is fine. It also does it with volume all the way down and on mute. What could it be and how much would it cost to fix. And can I do it myself the TV is a 1996 but other than that it works great.

SOURCE: The picture is very dark
Unfortunately, there is no easy fix for this. If it were a rear projection TV, I'd suggest a new bulb. Even on a Plasma there are things that can be done. But on a CRT, the repair for a dark screen usually costs more than replacing it.

SOURCE: picture is very dark
Is there a simple fix for this, yes The picture is very dark it is mostly due to 1 power supply output is low. 2 voltage on crt g2 pin is low. 3 video output supply is low. 4 some components in luminance section might be defective or loose. 5 finally crt getting weak but as you have bought in 2004 so possibility is rear. good luck

It's ring cracks on the solder joints of the vertical IC... IC421 i mounted to a small heat sink on the board. With the unit off and unplugged remove the board and locate IC421 (LA7832) and closely examine the pins connecting this component to the foil side of the board. You'll notice small rings around the footings that are actually open cracks in the solder, caused by heating and cooling over a period of years. Simply and carefully reflow some solder over these cracked joints, careful not to get the ic too hot in the process, and put it back together.. That should sole the problem...
Another problem we encounter a lot in the vertical deflection circuit of this unit are the two feeder caps C424 (100UF/35V) and C425 (470uf/35v).. If you're already there you might want to go ahead and replace these as well - save taking the back off again if they go bad..

Try this blog I found on this site. I have the same model and problem with my JVC TV set and I was able to fix it for 2 bucks at home by myself.
