Logically, those power supply adaptors should fit...unless Haier is selling an adaptor made with metric connectors. Is the connector a little too large or small to fit in the TV's socket for that adaptor?
If so, then this supplier seems to have the original adaptor.
Before you purchase this from them. can you answer my first statement above? I think I had the same problem as you several years ago when I was trying to fit a power adaptor to a Haier plasma TV set.
I trust Encompass, and Sears for the proper part. Sears seems to base their power supply on UK standards (just look how it's written in UK English) -
Notice the statement "MAINS PSU CORD"?
That's British. That's the way they speak about their power system.
Don't buy it...it may be designed for the UK, but the Encompass one would be for the USA.
I get a feeling that's why you keep getting power supplies that don't match your plug.
Oh and I'm NOT READY TO BE RATED...Just answer has locked the "I'm ready to be rated" box and I can't turn it off. Just reply back to me about the Plug size so I have some feedback about those Amazon power supplies, ok?
