Re: Re: Re: Re: JVC service or questions

Had the same problem with my JVC-32980.
Working one day, next day nothing.
changed out C926 with a 1000uF 35V capacitor that I bought at Radio Shack for $1.49. TV works like a champ. Took all of 20 minutes to fix.

  I have the same problem with JVC - 32980. Could you please give me a step by step how to replace the capacitor. Thanks.

  I have the same problem, and I too would appreciate if you could provide me a step-by-step detail on how to fix my loss of power on my JVC-36980. Thank you for your time.

    Hi i replaced c-926 with 1000@50v works great.

  Tom Pajewski,
  Thank you so much for your suggestion. Performed the same TVoscopy and it worked as advertised. Keith B

  Just found this posting. My folks have a, believe it or not, Mexican made in 1988 JVC tv of the same model series and it just died. I found Capacitor 926 easily on the circuit board and can't wait to operate! I'll try to let you know if this is the fix for me.
  
  Thanks for the info everyone.

  I had the same problem (no start) on my 1998 JVC AV36980. I just fixed it per your suggestion (replaced C-926, $1.79 from Radio Shack). Thank you for sharing! Saved me lots of time and money.

  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

      I just replaced the capacitor in my 1999 36" JVC. Works great. It was really easy to fix and it only cost me ~$1.60. My girlfriend was very impressed. Thanks for the advice.

      Had the same problem with a 9 year old JVC AV-32980. Purchased the capacitor at Radio Shack and replaced it. TV now working fine again. Thanks to all who posted info. on this repair!!

  I have a JVC AV-27980. I bought it in Vancouver Canada in August 1999. Just this October 2005 the TV did not want to turn on.
  
  My family was ready to buy a new TV. But 6 years is a short TV life. I've bought TV's from garage sales that must be around 20 years old, some even have dial channel changers. But they are still working! Needless to say I was very disappointed with JVC.
  
  I stumbled upon this forum and thought of postponing the purchase of a new TV. In Radio Shack, it cost me $1.59 for the 1000uF 35V capacitor and $7.99 for a soldering kit (which includes the gun, the solder and other accessories).
  
  I have only soldered once in high school so I was not confident. But it turned out not difficult at all. After opening the back, the only thing challenging was looking for C926. When I found it, I heated it with the soldering gun from under the circuit board to loosen the defective capacitor. Putting the new capacitor is a cinch, thanks to the previous posts in this forum.
  
  Nothing describes the satisfaction when the TV turns on and you saved a couple of hundred bucks for an equivalent TV. Thanks Tom and to the everyone who posted, you guys are making a difference.

  I have to chime in here. I am a very happy. I was watching TV when all of a sudden, it shut off just like someone had turned it off. I tried to turn it on with all the remotes, the power button on the front of the TV, nothing. So I looked at the power plug, checked the fuse, everything looked good. I thought I'd give the internet a shot, searched for 'JVC AV-36980 Power Problem' and came across this message board. After reading the several replies I thought I would give it a shot especially when I found a little black mark in the center of the cap top. The TV was useless without this repair. The part cost $1.59 at Radio Shack. Also I have a JVC AV-27980. It was manufactured in Mexico in August 1998. I hope to get another 10 years out of it now.

  This works! I the owner of a JVC AV-32980. I came home from vacation the other day and the thing would not power up at all - totally lifeless. A quick Google search yielded this thread, so I thought I'd give it a shot. I have no soldering experience and really had not idea what I was getting into. The hardest part of the whole thing was removing the back of the TV. You have to unscrew about 8 screws and slide the plastic back off. Once you do that you can see the motherboard, which can slide out of the TV chassis. There's several capacitors on the board, but on the bottom of the capacitor is actually marked C926 so you can make sure you've found the right one.
  
  I bought the capacitor and a soldering kit at Radioshack for under $10. You simply solder the old one off and put the new one on, then re-assemble and TV works just like it did before!
  
  Thanks to everyone for the valuable information!

    Thank you! Thank you! One more grateful person to add to the list! We just put in the 1000uF 50V capacitor and fixed our 36 inch JVC AV-36980 that all of a sudden wouldn't turn on after 10 years! Connie
