i built a couple k4306 and one works great and the other has a roblem on the right side.the led come on fine till the sixth one and when it lights the 11th one comes on tooand so on with the rest too. i did on first run have the chip in backwards(ic-6). i replaced all lm3916 but this is what it does but i did see it work corectly for about 15 or 20 mins on two ocasions then back to the senario i mentioned. it has stayed this way. i read forums thinking i might get lucky so i replaced r-13 and r-16 but no luck. i dont think any errors soldering exist…i think a part is burnt out (guess). when i short pins 5 and 6 on ic-3 all 15 led on right side lite up instead of just the first 10. any clues as to what to check next? i can get pics of it but i dont know how to upload them and i shure would not want to send it in if i can fix it.
thanx, numpskulls
