Re: sound no picture

Take back off lie flat

where the hd leads go into that board remove the screws at the top and bottom as its one long unit top to bottom
unscrew metal shield as well

remove all cables from board 2 ribbons are locked and require clipping down then ribbon removes
flip board over remove metal can to expose board notice 2 TSOP chips at top look att the pins one should look dull and not shiny

to fix i used heatgun a quick blast on pins sorted problem out

mask off board and chip around with metal etc... to not damage board.

Re: sound no picture

Disassembled my unit today. On the suggested digital board, there are a lot of surface mounted chips. The 29LV400 flash memory chip looked bad soldered under the magnifying glass. Resoldered the chip and voila the unit is working like new.

Olevia 242-S11. Have to turn tv off and on 6 times before sound stays on. No problem with picture.

Menu , sound settings, disable all special effects , Dolby surround, stereo, etc.. unplug, Wait overnight plug back in see if the problem continues if so, check sound settings they should be the way you left them

Flickers after 5min of use. Perfect sound, turns on fine and excellent picture quality when in blue screen menu mode. Why?

This intermittent problem is very difficult to rectify. Just contact the authorised service center for Hitachi at your town. The work is really a skilled one, that a user cannot do it with ease.

I have a Jvc - LT42EM59. The sound just stopped working but I have a perfect picture. ???

Check your mute button or the sound if going through a dvd or surround sound that will do it as well check the volumes on those. Try on the set the volume controls and then go into the menu and see if someone changed the settings.

Sound stays on, but no picture- goes black and stays that way.

This unit should still be under warranty and should be taken in for warranty service. Any attempt to access the interior will void the warranty. It is important that a complete description of the problem like you entered here be taken along when you bring the set in for service. This will insure that the servicer be able to reproduce the problem and resolve it.

From your description (and as a servicer), I would be looking for a component that is heat sensitive. These types of problems are fairly easy to locate and resolve.

Please take this in for warranty service and update this when you find out the details.

JVC 42 inch LCD HD TV has no picture or sound

utencilio posted this fix. It worked for my JVC LT-42X579.

Okay, I found a fix! Called JVC, spoke to somebody there, here it is:
1)unplug the TV completely, no wall no power strips, completely
2)wait 10 sec
3)plug TV back in and Turn it on, the light will still be doing the same thing
4)wait 30 sec
5)ON THE TV, not the remote, locate the menu, volume (-) and power button.
6)while simultaneously holding down the menu and volume (-) button, pressed the power button ONCE and continue to hold the other 2 for 10 sec.
7)on the remote control, go to menu>settings>system info
*** now this I know as a FACT will work on systems that display: JVC - ver.5.32FO001, but I don't know of any other versions***
8)press the mute button on the remote twice
9)unplugg TV again and wait 10 sec.
10) plug TV in and turn on

It SHOULD be working normally now... Thanx to the guys a JVC support for this one, I know it seems like an obvious first place to look, but sometimes it isn't. I for one checked online forums first

My JVC LT42X579 blue light stays on it won't turn off.

If what you mean is that the blue screen won't turn off (after about 5 minutes), so you should go the your tv menu options and select how much time in the blue screen option (under 'picture' or something like that).
