Re[2]: JVC service or questions

ADD ME TO THE LIST!! God I love the internet! My AV32980 quit working just like all the others on this forum. Working fine, then all of the sudden, boom, won't turn on. I was literally looking through the yellow pages to decide which repair shop to take it to, when I decided to just check the internet for any tips on repairing a JVC TV. Found this forum, read the other problem descriptions just like mine, figured that had to be it. In 45 minutes I went to Radio Shack, bought the 1000uf capacitor, got into the TV chassis, found the cap, de-soldered it, soldered in the new one, and walla! Working fine now. Forums like this are just an incredible resource for the folks. Obviously I would NEVER have even begun to know where to look for the problem without this help. Here's a little more info for those who follow: The capacitor you will find at Radio Shack is an AXIAL LEAD type, meeaning it has a wire lead coming out of each end of the device. The capacitor you will take out of the TV is a RADIAL LEAD type, meaning it has both leads coming out of one end. Don;t let this difference bother you. Just bend the leads so they will fit into the hole spacing on the PCB and position the new cap. nice and snug down. The capacitor is marked with which lead is negative. The board is marked with which hole is positive. As long as you get the polarity right the new style will work fine. Also, as suggested in this forum I went ahead and bought the 50 volt capacitor, hoping it will last longer. Seems to work fine so I would suggest that for others. It cost $2.59 instead of $1.69 for the 35v.

  I have a JVC AV32985 with a similar problem as the ones previously described but I do not know if it the same. The TV can not be powered on but the TIMER LED IS FLASHING (a symptom that I have not seen described in the previous cases of other persons). If I unplug the TV for a while and reconnect, I hear the TV screen going ON for about 5 seconds but it remain black then turns itself of and the timer led start flashing again.
  Please let me know if it is the same problem and I should do the C926 capacitor thing. Thanks in advance for helping me.

    I would bet that your TV shares the same circuit board with the others. Just a different size screen. I would try the capacitor replacement, it won;t hurt it if it is wrong.

      I tried it but it did not work. I will try a TV repair shop but here in Saltillo, Mexico, I am not sure they will be able to help as the TV was bought in Canada and I haven't seen any JVC distributor around here. Will see. Thanks for your reply.

    I have the same problem with a 36980. You can hear the Flyback fire for a few seconds when turned on and then the Flashing timer LED. The C926 cap is mushroomed so I am going to replace it this weekend. I hope that's the problem. Any luck Steve in finding the problem with your set? If so what did they tell you it was? Thanks John

      I changed the C926 with no luck. So I brought it to a repair shop and cost me $150 they claim they changed the power supply (which I doubt) but it works fine now so I won't argue. Good luck with yours and I hope C926 will do it (it it a really easy surgery to perform) Steve

  What capacitor are you talking about. I am having the same problem that it will not turn on and the fuse looks ok.

    I did this a long time ago and I do not have the specifics on the capacitor any more. But I got the exact info from the within the thread of the forum topic, so if you search and read thru the history of the forum thread you should find it. I do remember it is a large cylindrical cap., navy blue (or maybe black?) with white stripe, standing verticle approximately in the center of the circuit board pretty much all by itself. You might be able to see damage to it if the cap/ is bulging or scorched. I don;t recall the size but it was given in the forum postings and I found it easily at Radio Shack. IF you see such a cap. in the center of the board, but you can;t find the info in the forum, you could get the size number off of the cap., go buy one, and replace it and see if that is it. It will come with long leads with will have to be clipped. Also it may come with axial leads instead of end leads so you may have to bend them to fit in the board holes. Sorry this is all I remember. Look thru the forum history it should be

    OK a re-read the forum. It was a 1000uF, 35 V capictor. IT is just about right in the middle of the circuit board, standing verticle, a large cylindrical capacitor, can;t miss it. Replace with a 1000uF, 50V cap.

    Cap. is marked C

    Capacitor is marked C926 on the circuit board.

      I replaced it and never fixed the problem. I also replaced the fuse. We have a bad lightening storm and I think it was a power surge that got it. Is there anything else that may be the problem that would be fairly easy to fix.
