video TX destroyed by voltage mismatch

Recommended Posts

hello altogether,

yesterday i made a big mistake.

I changed Plus and minus pole from my video transmitter.

May be it was the weathe or my sunglasses, i dont know.

The TX is from Range Video (1000mw).

The voltage regulator is blown away.

Also i dont know the type of the ragulator.

Do you think there is a chance to repair the TX.

Do you think other components are also gone.

what a mess,

Uli

Too bad, my Airwave 500mW Video TX also did die a while ago, probaly because a hot regulator runaway condition :-/

Try changing the regulator, and search for destroyed/shorted tantal capacitors, and diodes etc.

Its probaly the only thing gone+maybe a little more.. :-)

It's hard to tell from the pic, but it looks more like a cap or diode to me. How many terminals does it have?

Looks like it will be a hard job as lots of damage to the board as well as the componant. With luck someone here will have one to compare it with.

I'm no brain but I agree Terry, looks pretty messed up. Board and all, but yeah with comparison to another working piece and lots of patient she can be alive again. ;)

i also think so.

I will try to get an other one and compare the TX´s .

May be i can fix it or not.

Problem is that Range Video and futurehobbies are out of stock.

Have to wait,

thank´s for your response, and greetings from germany

given the cost of a replacement, and the value of the complete plane, I wouldn't trust it in the air. I supose strictly for recording, but given the damage to the board it's a big risk for FPV. Esp given how hot these run, the expansion and contraction could easily break a fix over time.
