I recently picked up an old electronic Halex dart board. There are three, 3 digit lcd displays that need to be replaced. Two of them are smaller and one larger. All 3 have 22 pins. Has 9 v ac adapter w/ 500ma. Everything seems to work ok except for some burnt out segments on these displays. Does anybody know where I can find replacements for these? The 2 smaller displays have an overall measure of 3/4 by 1 1/2. The larger one is 1 1/16 by 1 5/16. Thanks if you can help me out.
