I have a 39-month old 40

You would have to order straight from the tv manufacturer. Many of us face that problem when buying a used tv that was mounted on the wall. You might be better off buying a wall mount instead. The base won’t be cheaper.

Parts are hard or impossible to find for this brand but it sounds like the "main" board which processes all signal in and out of the display.

My Olevia 42" television is several years old. In March of 2012, the infamous "TV will not power on" problem started.

The blue LED light on the front of the TV would go off for a split second, then light up again. The television would not start.

If you are handy with small tools and a soldering iron, you can change the capacitors on the power supply. My Olevia is a model 542-B11.

I bought the repair kit off eBay from seller: sghill99

As of this writing, the seller has sold 37 of these kits. The title of the auction is: Repair Kit, Olevia 542-B11, LCD TV, Capacitors

I made the repairs in March 2012 and it is now August 2012 and the television is still working great. It is turned on and off several times every day.

I just repaired this identical problem on the same model TV. You have a bad power supply (also known as an SMPS). The board is model FSP271-4F02, and is about $75. Unlike the main board for this TV, you can find the power board relatively easily. Try shopjimmy, for example. Replacing the board isn't too difficult if you have a reasonable mechanical ability, have some tools, and are careful.

Ur tv a LCD or Plasma tv?No,LCD and Plasma Tvs have a Digital tuner inside the tv to recieve free air DTV.Not require a Digital coverter box,if u have a LCD tv or a Plasma tv.U must have good antena thought like a roof or a digital antena,so ur tv picture don't cut in and out very often.

This company called Amergence Technology sells the Olevia Remote and will control any olevia television.

Ok I'm Not an expert on Olevia's but I've done enough LCD Tv's to know a few things. The inverter boards are usually located on the right and left side edges at the back of the chassis. They usually run from the top to the bottom and have multiple connectors coming out to feed the backlights in the LCD panel. I can believe Olevia might not supply them (most other companies do) except as a part of the LCD panel. In some cases, the manufacturer of the LCD panel (Olevia does not make their own panels) does not supply the boards separately to the company making the set..In terms of getting a diagram, the panel maker (probably chinese or korean) probably has one, but Olevia may not. Your best bet would be to keep an eye on a site like this one:

They get scrapped TV's and remove the inidividual boards for resale. I have already checked and they don't have the board you're looking for right now, but that can change. Sorry I can't be of more help!

Replaced two N-Channel Mosfet transistors(FQPF13N50CF-ND) and some faulty electrolytic caps in the power supply. I found the Mosfets online at Digi-Key. Mosfets are difficult to read. Only one read bad but I replaced both because they are in the same circuit. Set works great now.
