My Phillips 47 LCD TV is loosing picture but is keeping sound.

Main board feeds the t con board. However try the flash light test on set because it might just be the inverter board that powers the backlighting.

My vizio E470i-AO is about 2 years old only and I was shocked to discover last week that there was no picture and sound only. What could be the problem?

Go to Google and check out the flash light test. If you see an image then the problem lies with your inverter board. If no image than anomaly is with t con board.

Hi sathiavl,
If in the middle of tv screen a small light is coming lika a tube light, i'm afraid that broken panel. ( like hit by hard material). You must replace panel, but that very expensive. Or, that problem may because t-con, Open rear cover and you will see pcb t-con which attached on panel.
Clean connection between pcb main and t-con first, than turn it on.
if still problem , replace t-con board can solve your problem.
