I have a Vizio GV42L TV. Its about a 1-1/2 years old. Last

Resolved Question:

I have a Vizio GV42L TV. It's about a 1-1/2 years old. Last night while watching the TV we heard a "pop" and everything went black. Can't get anything to light up or turn on with remote or directly on TV. The VCR/DVD player plugged into the same surge protector is unaffected and still has power. Any ideas? Should I take it to a repair shop? Is it worth trying to diagnose and fix on my own? Thanks for any help.

It sounds like your power supply just went out, and it can be repair, or replace,and you probably, are looking around 250.

Is this something I can just order a new part myself and install or is it complicated enough that I need to take it into a repair shop? Also, is there a recommendation between repair or replace? Or would a repair shop that has seen the TV need to answer that? Thanks.

I will give you link where you can get a power supply. where you change out a power supply you just have to handle it carefully, and not tuck any of the transformer leads, and cap leads. I will get you a link where you should be able to purchase one, Also are you getting any clicks, led lights flashing.

No clicks or LED's flashing. I don't hear or see anything.

Then it is defiantly your power supply

Thanks for your help. So in general what is involved in changing the power supply? Is it fairly straight forward once I get in there? No soldering, just connectors?


And one last question. I found the power supply at for $123. I also found a refurbished one at for $72. Any reservations from your experience with going with the refurbed one?


Thanks again.

That is a good price, and just connectors and scwers. Remenber where the connectors go, you might what to mark the male and female connectors with a marker. Good luck.
