Question about JVC 47 in. LCD TV
We've power-cycled the TV, leaving it unplugged for 4+ hours today. When we turn it on, we can cycle through the inputs, but it has a white screen, with half of the screen being a little different color white than the other and "some" shows showing in that half of the screen, but they are in various shades of white. We have audio, too.
Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts.
In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

You most definately have bad capacitors in the power supply. try and get it repaired as soon as possible, not an expensive repair that iv'e seen.

Sorry, this has no easy fix. The good news is you do not need an LCD Panel. The bad news is the Video Processor has a problem.
This TV has x3 Boards. The one you should replace first is the one in the middle. If this doesn't fix it, try the one on the right. The Part #s are on the Boards if you wanna try ebay.

Hi , I have the same problem with my LT-42X688,so i called the service of my extended warranty provider . the TV technician just left and told me the motherboard is the problem. he said its the third one this week he has seen with the same symptoms. he ordered the motherboard and i've got to wait 5 to 7 work days before the part will be in . I will keep you posted when the guy will return.
