Power supply failure. Looking for schematic of power supply
The hayni made in china internal power supply has faulty transformers on it that fail within anywhere from 6 months to 2 years. Solution. Remove the back panel, take out the internal power supply and replace it with another compatible AC 120v to 12v DC 5amp power supply. Often laptop power adapters will work. I used this one: 60w-12v-5A-AC-DC-Power-Adapter from the website mini-box and it only cost 15 dollars. The peltier pad draws upwards of 5amps, but the rest of the system is super lower power. Now my wine cooler is more energy efficient and and will run for at least 5-10 years. This power supply replacement takes about 20 minutes. You need: philips screw driver, wire cutter and stripper, two 16 guage wire nuts. That's it.
Cut the tip of the of the cord off. This is the tip that would normally be inserted into your laptop. Then use a knife or razor and cut about 5 inches of shiething off. There should be two wires (Positive and Negative). The Positive is normally identifiable with a solid colored line running along the wire. If you have a DC volt meter you can test the two wires to determine which is positive vs negative. You can see in my picture the wires coming off the control board (Red and Black). The Red is your positive. Use the 16 gauge wire nuts to marry the + with the + and the - with the -
Here's the link to buy the power supplyhttp://www.mini-box.com/60w-12v-5A-AC-DC...
If the power supply you purchased has a ground wire, then you can ground that wire to the spot where the previous green wire was grounded (see picture above)
Not sure how you connected the power supply can you show more detailed discription thanks.
I added another picture with some info that may help you determine how to connect the Laptop PSU wires.
Thanks got it however my unit has only one board, cwc1600 I'll figure it out how to install the power supply, I'll take power cords from board and connect to power supply.

Please explain, if you could, what to do with the wiring from the laptop power supply into the cooler, in a little more detail please.
