Try ShopJimmy.com, or Ebay. Just be careful when buying from ebay, look for good seller with a return policy.

You can see devices mounted to that heatsink, right?

Check them for shorts. Typically, they are MOSFETs (3 legged devices.) You do not need to remove them from the board to do the test.

To test for shorts, use the same mode on your meter that you used for fuses. Except this time, a reading of near zero is bad. Test all three combinations of pins (pins 1-2, 2-3 and 3-1) the polarity does not matter for a quick check like this.

If you find a device with more than 3 legs on that heatsink, please advise the part number printed on it so we can indicate where to test.

hi hello! my name is Al. I'm sorry for the interruption. I'm also having the same issue, but mine reads .5 and 1.5. I'm new to this too. Is mine bad too with those readings?

Same basic steps...Do you have soldering experience ?
IF NOT, it might be easier for you to replace the board !
