Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

SOURCE: vizio vx42L no power will not come on just went

First place to check will be the power supply, look for blown fuse, burnt parts, bad caps with bulging tops. Check for DC voltages, you should have 5, 12, and 24vdc at the power supply DC output connectors.
Parts: check www.shopjimmy.com

SOURCE: Vizio VX42L LCD TV died?

it is the power supply. in the given scenario like yours, the PSU is the suspect in 90% of the cases.

Testimonial: "alteans is very helpful."

SOURCE: My Vizio VX42L is flashing like a strobe light.

Mine did the same thing. Remove the stand and back of the tv. Be careful with screen do not lay on hard surface and scratch. When you take the back off you will see a board on the left side and a board on the right side. They are labeled slave and master. Remove the ribbon cables and take board out. There are 2 capacitors on each board (about an inch long). These are probably all bad (ends bulged a little with black stuff on bulged end). Radio shack has them for less than $2.00 each. turn the board over and you can read the size of the capacitor. You need someone who can use solder wick and remove all four capacitors and solder in new ones. Notice how the capacitors are turned. Each one is labeled with a dash for negative. Make sure you bend new capacitor connectors the same and put back in the same way. Put the boards back in the tv and attach all ribbon cables. Put back and stand on. hook up your power and cable box and you are ready to watch tv with no more strobe. Me, my husband, and son did ours last week. I looked up the problem on the internet, husband removed stand & back, son with the steady hand did the soldering. Family project that went well for once.

SOURCE: I. Have a vizio 42" led tv i took off the back panel but i could not find where the T-con board . Does this tv have one or is it integrated to the main board. Thanks

To some model sets, T'Con board will be a built in part of the display panel; and cannot be replaced. If the T'Con board go bad to these type sets, display panel should be replaced.
To some other models, this board can be located at the back of the panel itself. Normally it will be fitted under metal shield. Just see the pictures.
