Re: JVC service or questionsTim Posted Sep 07, 2005, in response to:Tom Pajewski
SKEPTICAL... that's what I was. But I thought, "What does it hurt to see if I could find capacitor C926." My problem started off as I couldn't turn off the TV, either with the remote or the button on the front of the set... just kept coming back on. So I unplugged it. Next day I went to plug it in but it was dead. So I spent labor day tearing apart my 7 yr old JVC AV-32980. Finally found C926. Noticed the top looked slightly bulged compared to other capacitors on the board (someone else mentioned that). Also noticed it looked slightly wet at the base (on an otherwise dry, dusty board). Hum... I wonder. Got the part from Radio Shack for $1.59, removed the old part, soldered the new one in place... FIXED!! Thanks for this forum. Saved me some bucks, I'm sure.

Alex -- To replace the C926, 35V 1000mf capacitor you need a soldering iron or soldering gun and TV-radio solder. First note the polarity of the capacitor as it is mounted on the board. There is a positive and negative terminal (If I remember right, I think I discovered the vertical stripe on the capacitor marks the negative lead. The bottom of the circuit board shows which lead is positive.) Next, use the solder gun on the bottom of the board to heat both solder joints of the capacitor (one at a time) until the solder loosens enough to free the joints and push the terminals through the board. (Trim the terminal wires with diagonal cutters first if they are too long.) Use needle nose plier to lift the capacitor free so you don't burn fingers. You are now ready to put the new capacitor in place. (By the way, I would get the replacement part at Radio Shack before you ever begin to remove the old part.) Trim the leads on the new capacitor before you put them through the holes on the board (not too short but short enough) and make sure you have the polarity right (see above). Once the capacitor is seated to the board, bend the leads slightly so the capacitor stays in place while you solder. Assuming soldering electronic parts is new to you, the rule is: heat the work, not the solder. Touch the solder to the work joint, not the gun. When the lead gets hot enough, the solder will begin to melt. (Melting the solder directly with the gun usually creates a "cold" joint which results in poor or no connectivity at all.) Hope this helps. Good Luck! --Tim
