No display/picture. Sound and power work perfectly.
The title basically says it all. One day, out of the blue, I turned on the TV set and the picture would not load. I had perfect sound, could change channels, could switch inputs. The TV looks as though it is going to work fine at first but the screen cuts out just before the picture should appear.
I found three potential solutions. 1) There is someone on Craigslist who I was in contact with via e-mail. He said he could fix the problem for $100-$200 if I ship him the TV set. He is based in Canada somewhere.
2) There is a guy on E-bay who claims to be an expert. He auctions 20 minutes of time on the phone with you and his auction starts at a few dollars plus a $16 "shipping fee" that he says must be paid before he will talk to you. His auction even lists the exact Norcent problem, although the auction ended already. In his product description he says he knows how to fix "some frequent issues such as Norcent: TV on but no display."
3) I found a shop called All Electronics in Raleight, NC that claims to have worked on Norcent's before.
So, I decided to bring my TV to Raleigh. They took it last week and charged me $20 and told me they'd call me as soon as they had a chance to diagnose it. I decided not to spend $50 to ship it to Canada or $20 to talk to some stranger. I will update this when I hear back from All Electronics.

Re: No display/picture. Sound and power work perfectly.
Based on your problem listing I believe you have an LCD tv. You can check your tv by turning it on to a station that normally
shows a good picture. Shine a bright flashlight and place it against the screen. Look around the edge of the flashlight for an image moving around. If you see it, your problem is with the inverter/CCFL..
a 6ya expert can help you resolve that issue over the phone in a minute or two.

To achieve true life like colors, the primary colors need to be balanced to produce a perfect black and white picture. Turn the color level on the tv to 0 and tint to middle then look at the picture - does it have a reddish or other "coloration" to it? Then set the individual color levels (if your TV has these settings) of red, blue and green to balance out and get a true black and white picture. After that, bring the color level up slowly until the facial levels are natural - not over driven as seen in most store displays. You may need to use tint control slightly.....
One other way - There is a dvd from Disney called "Wow" that aids in getting your set to optimum display.
Possible cause of the problrm is bad/poor solder on the grounds for the tuner circuit shield an the bottom (solder side) of the circuit board. Grounds need a wire jumper from point to point. This was a common problem for those sets and ocassionally it would take out the eeprom chip with it. (Various other problems were shrinking picture/fuzzy picture and intermitt. power)
"I am also having difficulties in try to display the yamaha set up menu on the tv." According to the manual the display menu for TV will not work with HDMI hook up. I also have a Panasonic HD TV and can't get TV sound through my Yamaha AVR on "TV Sound" mode. Trying to use HDMI cable for this also. Do I need a digital optical cable or do I not have something set right?
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
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
