I ordered the unit off of ebay. Well the seller did a very poor job of packing the unit for shipping (he used news paper to hold it in place). When it arrived, the top corner where the power button is was crushed and you could see the inside. Upon closer inspection, a corner of the circuit board was broken off. I've already gotten the money back from my order, but i would still like to fix it. I've contacted Sony to see if they'll even tell me a part number, but I doubt they will. I'm continuing to use the internet to see if I can find anything, but would appreciate any help that people could provide. Thank you.

Re: Broken Power Switch Circuit Board
Dont feel bad, i had the same exact problem from ebay not packing rite, a broken Circuit board is a combination of wiring and components that provides a path for the flow of electricity, since its broke the flow is probly disrupted, did you try to poke the lil button witch the switch would hit an turn it on, try an push the lil black rubber dot with a tooth pic? it still mite come on if a lil piece was broken long as no other were. if it dont then it needs replaced, an sony prob wount return ur anwser since this world revolves around money, bet yet again they could be nice enough, try that its worth a shot at it, if you havnt already

It more than likely not the sellers fault ,but the Postal services fault the package was not delivered. You can change to negative feedback to naturale. I am also a seller on eBay I am sick of my packages not being delivered just because the Postal Service can`t do there job. But is the sellers that have to accept negative feedback and even have give the money back also .
Notify the seller about the broken items. Between you and the seller you'll need to determine if the items were broken by the shipper. If so, the seller will file a claim for the broken items. It's up to the seller whether he refunds you prior to the claim being approved. I usually refund as soon as possible. If the seller is unresponsive and/or he did not purchase shipping insurance then you'll nee to file a claim with eBay's New Buyer Assurance. Good luck
I had a similar problem to this. It turned out that the button on the main circuit board was broken. Take the cover off the printer and look at the main circuit board for any damage. I replaced the broken button and the printer turned on right away. Another option you can try is to replace the entire board if you can find a "parts" printer on ebay.
Ebay is where I get all my parts, there are literally hundreds of stores that have used and salvaged parts, I have visited many of them and save them to my favorite sellers list. Then, even if something isn't listed in Ebay doesn't mean they don't have it in the their inventory. You can search each individual store and you do not have to go through ebay to buy something, Ebay is just good to find the stores to do business with.
You can buy a power switch circuit board replacement part off of ebay for under $5 (typically shipped from China). Buying the circuit board is easier than buying only the switch, since it avoids having to do any soldering. The power switch board can easily be swapped out and a new one reattached by connecting a few connectors.
I have the same problem. I was thinking one solution for us, but I don't like it might be to solder the power supply on and skip that female plug entirely. To do that, you cut the male end off the transformer/power supply wire (if you don't want to ruin your transformer/power supply you can buy another power supply at Best Buy for $10 - Dynex DX-C1109). Then strip the ends from each wire from the power supply so you have some bare wire showing on each wire. One goes on the spiral thing sticking up from the JCM470 board, the other goes anywhere you want on the red wire coming from the battery compartment. You should test before you solder to make sure you the proper one on the proper wire and that you therefore have power to the unit and it makes a sound. But its a sloppy fix. While it should work perfectly, the power pack then can't be changed unless you solder and unsolder it each time. Another solution is to find a broken LK-30 or LK-33 and rob the circuit board if it still works on the parts machine. Trouble is if you find one and its not near you it costs some money to ship these. At some point its just easier to buy a used one on Ebay or craigslist.com, I guess.
