Hello, If you are referring to the actual shape of the prongs coming out of the tv plug(refer to figure): if the prongs look like this, you will have to acquire an ac adaptor for your TV, this adaptor you can locate at any radioshack store, and sometimes it's called foreign ac adapters for US use.
or simply look at the radioshack webpage, it should be listed under ac adapters.
The first thing I would suspect is a noisy AC supply. Try using a
ground adaptor. Sounds technical, but if you every went to Grandpa's
he may have been using a few and you just didn't know what they were.
They are commonly used to adapt a 3 prong electrical plug to a 2 prong
AC outlet. If your TV does have a 3 prong AC cord, give this a try
before you do anything. It's a cheap solution and often works like a
1 Take the old power cord, as a sample, to any of the electronics shop in your area or nearby. Make sure that the new one has the same voltage and ampere ratings as the old one.
2 You can also contact the retailer from where you purchased the TV
3 You can also go online and get the power cord from stores like Best Buy, Circuitcity,Radioshack, amazon.com,walmart etc
This model can be sucessfully refurbished, we charge 125. in our shop. The manufacturer uses very cheap components that "bake" out.
I havn't seen any decent replacement. Keep in mind..this power supply has 2 outputs. I believe some pple try to replace it with a single output replacement because the connector to the lcd is the same connector.
It seem to be the #1 common problem with the Protron TV.
It maybe cheaper to find someone to fix the power supply, but if you get it from LCDPAYLESS, make sure it has some type of warranty on it. I hate to see anyone pay $130 and it only last a couple of months.
