LOCATING YHI AC POWER ADAPTOR OR EQULIVANT OR REPAIR.
Apparently, this company, YHI, is no longer in business or they were purchased by some other company. I have read that many people misspell the Model # and use the 1 INSTEAD OF CAPITAL I in describing the model #. I do not know if this makes a difference..Do you have any repair people in the ft myers/cape coral fl area that can fix these.

What is the current output of the adaptor? If it is AC and you use only the 12v to 3v it is ok. But if the current output of the adaptor is DC and you use both 24v to 6v and 12v to 3v there is some danger if use the new one. Remember that DC current have polarity.
To my understanding, any power adapter would serve the purpose as long as the replacement adapter have the same specification as that of the original. Pls confirm, 100-240V 50-60HZ 3.0A max. output +25 6A +12 3A. The only limiting factor is that the plug/connector should fit the jack of the TV unit.
Having said that, then most electronics store would have a generic replacement. You can even look for replacement from computer stores. Over the counter sale would not need a PayPal account, and cash sale would of course not require a credit card. It would be to your advantage to bring along the original/defective with you to compare/as per sample.
I have a 32'' Sova LCD tv with the same problem. The problem maybe your power supply. In my case, it was the power supply (no.# YHi 090-02180-13) it had no voltage out put, no blue light and no working fan. Remove the power supply and take it to your local repair center and check it for voltage out put. I found it difficult to locate the same power supply after the decision not to repair mine. There is an alternative I found on ebay, it doesn't look the same, but all the spec checks out. I had this power supply for two days and my tv work great so far so good.
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. I repair these at my work, so here’s the shipping address: Dave Simpson 23372 South Pointe Dr. Ste. B Laguna Hills, CA 92653 Also, I’m set up for PayPal. firstname.lastname@example.org
