ORIGINAL: BLTP I've been using my A9 for serveral months and I love this radio. I have been looking forward to the new firmware release and been checking daily to see if its ready. Anyhow I have been using hyperion 2s Lipos since the first week I got this TX and never had an issue. I went to switch my lipo to my spare and when I went to hook up the new lipo I accidently aligned it upside down, for litteraly 1/2 a second if that. I mean i litteraly only lined it up for a millisecond and it barely touched the pins. i mean the connector is keyed and you cant even push it on wrong even if you wanted to. Anyhow I cant understand what happened, because my power switched off on the TX and like i said the pins barely touched! The radio doesnt turn on and now and cant afford to shell out money for a new one.
My good friend/coworker is a CE/IE and has lots of experience building , designing and reparing digital circuts , power supplies etc. I'm wondering if anyone else has done something similar and can point me in the right direction as to fixing it. .

Best contact Hitec Warranty & Service (otherwise local distributor if outside USA) for estimated cost range as required repair may involve more than just that capacitor.
