    People buy boards from Shop Jimmy, which is a reputable dealer, but what boards are you going to replace, Power Supply, Mainboard, T-Conn, LED strips? Without the knowledge, it's all guesswork. Unless you can see damage to a board, all the boards will look fine.

Visio VX32L has a black screen, appears to power on but picture.

Any swelling on a cap is bad sometime you wont see swelling ontop sometimes its on the bottom, I suggest replacing those caps then try again make sure you discharge the caps as well.
Also make sure its the right caps too!

I have a 42" Visio

I would try to look on the power supply first for popped capacitors that supply the 24v rail for the backlight inverter.

Having sound is a positive when it comes to repair. This means that only your screen is not lighting.

If you repair the 24v line and check the 5v feed also going to the BN_on (on) the backlight inverter and you still have no will need a new backlight inverter.

Hope this helps! Please rate!

Visio 42in. Plasma TV

The TV is a Plasma, it does not have a "BackLight" as it were, that is for LCD's only.

Vizio are fobbing you off. It will need either a Y-Sustain & Buffers or a Z-Sustain.
