Hi!

If anyone would like a Power adapter for their Ultra LCD30-500 and LCD40-500 - please email me [email protected]... 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.

I see so many here with no sound/nopicture issues:ISSUES: 1. IF sound main fuse/s are good.2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.4. Be safe and if you do not know what you are doing don't open the set.Answers to issues:1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.3. Trouble shooting consists of the above and then at some point you have tobuy and try a board to see if it fixes it or not.4. Safety first--no TV set is worth getting injured or even killed over.Look at power supply board in the set to see if any caps are puffed up on top like these bad ones.

I have the LCD30-500 too and was told that by a repair shop that it needs a new power supply AD-13D-2. I got the power supply but the problem still remains. The power light turns from red to blue but no picture on the screen.

These power adaptors are no longer being manufactured or hard to find. You can search for the adaptor part number AD-14E-1 or I can repair it for you.
Let me know if you need further assistance.

Where does the power cord plug in?
