  JVC 27" COLOR TV MODEL AV-27BM6
  Problem: After TV has warmed up...TV will just loose its picture and only displays a black screen. Power light is still on. TV can be powered off then on with remote to bring screen back again.
  
  Is there a simple solution to fix this problem?
  If there is a simple solution, can you email it to me for free?
  Or ???
  Or will it need to be professionally addressed?
  If professionally addressed, about how much will it cost to repair?
  
  Thank you

  I have a JVC GR-DVL520U. When you turn it on looking through the lens or through the screen you it looks like your viewing things through a strobe light or something. The whole image is flashing. When I look through the lens from the front I can see something moving very fast. Also when I opened the camera to put in a tape the little door didn't open and the mechanism just makes a noise like its trying to open, but it can't. I dont know if this is going to need to be sent in and if it does need to be how much it is going to cost me :( I've owned it since 2002 but it was like in 2003 or 2004 that it started doing the flashing thing (the door thing is new). Do you know what the issue is?

  My JVC GR-D50A keeps displaying 'Safeguard mode' and tells me to eject the tape and reload it to be able to proceed. I have tried this method without success and am wondering if there is a wayto get out of 'Safeguard mode'?

  Hi there,
  
  I have a JVC DVD/ HDD Video recorder DR-MH30S/DR-MH20S and up until a few weeks ago it has been working fine. However, now whenever we watch the TV via the DVD, or try and watch any DVDs or anything recorded onto the HDD we cannot hear anything but bad static. I've looked on a troubleshooting website and found a similar problem with the following solution:
  
  NO it doesn't sound like there related problems at all. Now you say you get interference or is it more like a static noise only when using the dvd player??? If that's the case then you have an output device problem as its breaking down and crackling into your input to your sound amp or the tv. Its a problem that will need to be traced with a scope and a test disk. as it could be a D to a converter or an op amp IC, or even as simple as a filter cap. Good Luck
  
  
  What does this mean and what do I need to do?? I live in England.

• JVC AV-32980 power issues Per-Ola - 26th Feb 2007 7:56
  Our JVC AV-32980 (32" CRT TV) was working fine one evening. Next morning I was to turn it on, nothing. Stone dead.
  
  About to haul it out of the house to a TV repair shop, but decided to look on-line first. 2nd hit in google (after one ad for a manual) was pointing to this forum and directly to a common problem with capacitor C926.
  
  Took the TV apart, a little while to locate C926 but once done, I sort of could trace a "clean" area under/around the capacitor (rest of mainboard was covered in dust). Soldered it out and it was pretty clear that this little capacitor had had a small amout of electrolyte leaking out of it.
  
  Did pass by RadioShack today and picked up a new 1000uF 35V capacitor (article number 272-1032). Price $1.73 including WA tax.
  
  Back home, solder new capacitor into place and try power the TV up. Starts-up, just like before. Wow, $1.73! Put the back cover on again, lift the TV onto its stand and connect all the cables.
  
  EVERYTHING works as before EXCEPT that the TV no longer reacts to the signals from the remote control. Tried with both the JVC remote and a few generic ones. TV works, but does not pick up commands from remote. Front panel buttons all works.
  
  Anyone has any idea what could be wrong? Just go back in and "wiggle" a few connections, or does anyone know what module that is the "remote commander"?
  
  Apart from that, many thanks to several posters in this forum. Without you, I'd never been able to find the C926 problem!

    What you mention would suggest a much simpler fault than possibly thought, as the section you refer to is not connected to the area that you made the repair in. I would have a look at the IR control pick up sensor to make sure that you haven't either bent it out of position, unwittingly disconnected it or alternatively accidentally blocked its view when you re-assembled the chassis.

      All advice is appreciated and this forum alrewady helped solve the "main" problem (C926). But, in this case I sort of looked at all those simple issues first. The remote control receiver sits on the same small board as the five front panel buttons, just below the tube. All buttons works fine. The board is connected back to the mainboard via 5-pole ribbon cable. Will have to place TV (heavy) on its "belly" again and open it up and "wiggle" around. Will let you know outcome when done. Hopefully is is like you said something very simple.

    Well, turns out TV is working fien with remote as well. Just sort of happend to touch a button on a different JVC remote control one night (remote for A/V receiver). TV turned off and on again. No other controls for a TV on that remote. It was not until the following day that I realized that the TV actually was working (must have been tired). Tried with its normal remote, and all good again. TV's just like before. Hence, no idea what created this problem, if there ever was a "real" problem, and no actions were taken to fix it. I was dragging my feet to have to open up the TV again and at least "wiggle" some connections. But, thanks to this forum, I managed to get directed to the "C926" problem and fix that one. It solved the "non-starting" TV and all is good in the family again. Thanks for the psotings, and the e-mails I've gotten with suggestion on where to look.

    I would also like to say thanks to those who notified this forum of the capacitor issue on this model. Mine went dead last night, found the tip here this morning and did the same thing. Went to radio shack for the cap and replaced it. Works fine. Thanks again!

  Hi .. hope all is well. My JVC 27530 crt tv color is getting dark and red. Just over 2 1/2 years old. What do think might be the problem ? Is it the tv tube or would it be the drive circuit. And, if it is the drive circuit, where would I locate it ?
  thanks for your help .
