Where to get a Power FC repaired?

[boost86]

I'm looking to get my Power FC repaired, but I've heard Apexi's turn around time can be a couple months.

Another thing is.. How could I get my hands on a schematic for the Power FC? If I had a schematic, I could take it to somebody who I know locally and he could fix it.

Basically what I'm asking for is contact information of known PFC gurus or a schematic.

What exactly is wrong with it?

Is the circuit board fried? I mean it may not be repairable bud

The power fc has lost control of the injectors. The car runs insanely rich if I run the power fc because the injectors will dump as much fuel as they want into the car.

By physically examining the circuit board, everything appears to be in good shape.

At this point, I believe the problem lies with one of the mos fet transistors on the board that is linked to the injectors.

Part number: NEC uPA1556A

I'll post an update as soon as I get a new one soldered on the board.

I was going to jokingly say 'contact motec', but i give credit if you fix it yourself. I had to do a similar thing to a LCDTV last year that was just out of warranty.

also, that capacitor, the dark one in the middle right side, is it popped?

Since I didn't really have any options for getting it fixed, I took it upon myself to handle it. The biggest difficulty with my situation is I'm working 10+ hour days, and you know how that is.

That capacitor is good. In addition, all of the capacitors and resistors appear to be fine. Just to be uber sure, I should probably run a multimeter check on everything. I'll keep ya posted.

Btw, props on fixing the tv. I love DIY fixes.
