I tried to purchase one for the $142.00 and it was not in stock. I think contaced the person someone recommended on this website. This was his answer:

It seems a lot of people are having problems with the Protron power supply. I’ve been able to repair all the ones I’ve seen so I’m confident I can fix them. I don’t sell the replacement power supply but I’ve heard about the ones on EBay. They seem to be a mishmash of two power supplies (12vdc and 24vdc) wired together with the proper connector. This should work but it just doesn’t sound very clean looking to me and they end up costing $150.

I’ve been charging between $50 and $100 to repair these power supplies. My recommendation would be to send me the power supply I’ll check it out and unless it’s unusually damaged it will cost $50 plus shipping to repair. If I can’t repair it I’ll return ship it and only charge for shipping.

I will guarantee the repair for 1 month. I don’t know what’s causing the power supplies to fail so I can’t guarantee it any longer than that. My feeling about the reason the Protron power supply stops working is two part; could be overheating due to lack of proper ventilation to the power supply; or the TVs power requirement is overdriving the power supply.

Feel free to contact me if you have any questions.
