Re: tcp50g10 one blink

Just to check, did you try isolating all the ribbons along the C boards but leave everything else in?
5 blinks is 5V detect, I think. You might have to find the 5V DET test point on the C boards and see if that is testing bad.

Re: tcp50g10 one blink

Ok so I let the power bleed off for an hour before swapping boards and retesting the end result was identical.

5 Flashes with everything plugged in and 6 with the SC board removed.

SO it must be the SC board.

I see on eBay that people have "rebuild kits" for the SC board. Looks like transistors that are commonly blown on these units. How hard is it to soldier those things on?

I would follow TOMs advice and also I would poke around the SC and see if you can find any shorted transistors. Maybe measure resistance across SC2, 5v and 15V lines on the SC.

If it's definitely the Sc and the Sd/Su are ok, I would get someone who knows what they are doing to repair it.

The kits are not a all-in-one fix everything. Most mention only certain blink codes for their kits.

There's 1 guy on Ebay with 100% and a few people have had success there.

I have a couple of open circuits on the test points specifically TP46. Would there be any set OPEN when there was no power on the board?
