Question about Vizio L32 32 in. LCD HDTV
It can be the power supply problem, or the power supply detected shorted circuits so it goes into shutdown mode.
You need to at least open it up and look inside for any bad caps with leaking/bulging tops, you may also have to disconnect the cable from the power supply to the backlights inverter board to see if the TV will stay on (it will have sound but no pictures of course).
You can see the pictures of the boards at www.shopjimmy.com so you will know what the boards look like.
The one shown in my picutres here had blown power supply module and also bad T-CON board, so for the set this old, you can expcet more problem later on.
Most parts that go bad in LCD TV are the power supply module, backlights inverter board, and T-CON board.
