Most likely bad capacitors. They can be replaced but I wouldn't recommend a novice trying to do so. It requires soldering skills. If you can get into the monitors and check the inverter boards to see if any of the caps look like the ones in this video http://www.youtube.com/watch?v=oDGjWOabJ2E that would be a start. At least then you're armed with knowledge before getting overcharged by someone who wants to charge you a couple hundred bucks to replace a couple $4 caps.
Hope this helps.....

Whatever a willing buyer will pay for them in regards to condition of resolution and age.Because these will now be third hand if you sell them on the value may well be lower. The average sales of Javelin LC 32" second hand is about 100-150 each. The 42" can bring 180-240
Please rate my help++++Thanks for using FIXYA

i would imagine that the screen has gone bad.sense you said it started to fade..screen replacement is very easy on the V3. There are 4 screws on the cover under little rubber pucks.Then gently pop the back off.and you'll see the camera and the ribbon cables ..undo them carefully, the rest is very self explaining.

log off; find button called ease of acces; find the field called on screen keyboard and click on that

Look at the venting grills, you should see whit lights inside the set. If not, the backlight inverter board may have gone out or the power supply supplying the power to the inverter board may have gone out. Those are the two places to look first. It may have bad capacitors in the power supply.
