JVC 32" TV model AV-32980Tony Cooper Posted Nov 30, 2003
Not sure what I need, but I can repair.
The TV will not turn on. And that's about all I know. Neither the power button on the front of the unit nor the remote can turn on the TV. Just the previous night, it was working fine. The unit has been in operation for less than five years. I can do the repairs... I just need to know what's wrong and where to find the parts. Many thanks.

Mine did same thing two days ago... January 27, 2005... I want my tv fixed... I love the TV Guide Plus and can't find other TVs that have that feature... HELP!!!
A BIG thanks to Art and Rich P. for diagnosing this issue since it appears to be a common (and growing) problem. I recently ran into the same problem on my AV-32980 TV set and found that replacing C926 with a new part solved my problem. I did not find any visible signs of damage or wear when I removed the old part so don't let that stop you if you are experiencing this phenomenon. The capacitor I removed is a Rubycon 1000uF, 35V electolytic part from their "YK" product family. If you lookup this part on Rubycon's web site you will find that this part has a rated lifetime of 2000 hours. Gee, that's about 1.5 Hr's a day for 4 years so not what I would consider a "robust" design. No doubt this "lifetime" will be affected by the voltage levels the part sees during its life, temperature, ripple current, etc. .... it makes me think that the design, test and QA group at JVC might have missed this one. Oh well, $1.59 at Radio Shack and I'm back in business. Thanks again.
I had the same problem and my TV has been sitting for a year until i read this post. I replaced the Cap and it work again. the can was only slightly bulged - thanks
Exact same problem here. Sounds like JVC put out a defective part. Can an amateur like me fix it - or do I need to pay $100+ for labor?
All right i got it. The cap is C926 a 1000uF @35v cap.Replaced and my set was cured.
Hey guys, I had the same problem in May of 2004 - no idea why - I took it to a JVC repair shop and they said it needed a new cpu chip - $200.00, they called me today (2 months later) and they now say they want $175.00 more to fix it - I don't recall the part name but it's something like "horizonal stabalizer" is this S#!t or what? What should I do? any comments are welcome
Thanks Rich P. I replaced C926 with a replacement from Radio Shack. It cost me $1.49. Works like a champ. Such a coincidence that the same component is failing at about the same time.
my set dead to. The turn on relay goes in and out repeatedly.Looks like a cap in the power supply may be swollen on the top.If anyone figures out the value or location number let us all know. Rich
I replaced a cap which fixed this problem. I don't recall the cap location number or the size tho'. It's in the middle of the power supply chain and facing the rear of the board it's middle right. About 1 inch tall, 1/2 inch around, all by itself with reguards to size. After this was replaced it works like it did before the problem.
Finally figured it out, there is a capacitor in the middle of the power supply that went bad. I was saving the cap for a while to post up what it was, however the S.O. decided it was trash. Middle right hand side of the board, facing the back side. I thought it was c32, but don't hold me to that. I honestly don't remember what the uf was on it, it's about 1 inch tall, 1/2 inch around. After replacement works like it did before it went out. art
