Question about Flat Panel Televisions
We recently moved and lost the power cord/supply to our Nova LCD tv. I have tried getting in touch with the manufacturer to order a replacement but they seem to have gone out of business!
The manual says we need an:
AC Input: 100-240V, 50/60Hz, 0.5A
DC Output: 12V, 4A (Max)
I have found some cords, but they all seem to have an AC input amperage of 1.5, not 0.5 as the manual says. Any suggestions as to where to get the right cord, or if the 1.5 cord will work without damaging my tv or electrical system?

As I search the internet I found out no replacement for this kind of the adaptor model number 090-02180-13, there are some people looking for this kind of adaptor is a faulty a pervasive problem with the TV. There are literally hundreds of complaints on the internet. Most deal with a faulty AC Adaptor and the inability of the company to provide a replacement part.
I have a solution for this adaptor problem we better improvised the parts inside. The faulty parts of this adaptor arise in the transformer. This transformer is easily to burnt because of lower amperage. So we make it higher amperage so it can resist the load heat and cannot burnt easily.
Maybe you can do this for yourself, open the adaptor case, when open already look for the transformer, the visual picture of transformer is a bulky metal with many windings. Take this out and bring it to electronic shop that know how to rewind a transformer. Tell them to reworks or rewind the transformer, only the output voltage will be change input is the same. This is the
When i search i found a site that can make an ac adaptor only you give the new specification and give where you are using the adaptor give the brand name PLTV-32 and they will make it..try this option also ..LCDPAYLESS.COM

If anyone would like a Power adapter for their Ultra LCD30-500 and LCD40-500 - please email me Acosta.email@example.com... And I’ll be able to order one…
I too own a Ultra Lcd40-500 HDTV. Bought it from HSN.com back in 2006.
My power adapter burned out 2 weeks ago, and to my dismay PWW, or should I say POS has gone bankrupt.
I looked everywhere online and here in San Jose,CA thinking I would find a replacement or at least someone that could repair the blown capacitor( 630v vpmm), thermitors(IRFD460A) and varistor( SCK206).
After calling every power supply company, distributor, and retailer, had no luck finding a match to this crazy looking 9din pin adapter. Disappointed I gave up on a replacement and took it to various repair shops for repair and was told without schematic would be nearly impossible to replicate the power Output. Finally this one shop was able to replace the burned out components and it seem to work at the store. When I got home with it..no luck..red light would come on…but no light on screen. L
Not wanting to give up or trash my LCD. It was time to dig further…I did some research through my employer; a SemiConductor company here in Santa Clara, CA.
Needless to say this power adapter has driven me crazy….It has been exhausting... But finally just yesterday I got the break needed…I found a manufacturer in Taiwan that has these power supplies for both the Ultra lcd 30" and 40". I was told they only sell to Component or Electronic Suppliers. I’ve asked my employer to see if I would be able to order one on their behalf using their account.
Happy ending! My power supply is on it’s way. I was told it could take up to 4weeks for delivery. But I’m just glad to have a replacement.
