As you can see on the picture, one component has burnt on the tx (at the bottom near ts330 writing). However I can always transmit the signal with the sound, but no image. And when the tx is on, the TV screen is going black without frying. I mean there is no BSOD.
Do you think guys, it's possible to fix it? If you have an idea I'm interested.
Do you mean that to make it work properly it will need 2 power supplies ? TX in and CAM?
Or i can just make a new wire betwteen the cam and the tx signal ?
I just used 1 battery except modified the wire harness to reattach the hot wire from the transmitter to the main pack. I have attached a photo of what I did.
I hope it works
Thx for the schema. I've tried it today, it seems that i have something (white rolls on the blackscreen) but no images. Maybe it's my camera that can't support 12v mmm
exactly same component fried to me.. It was working normally and imaging started to roll like you said.... Its sad! Did you manage to fix it?
Eric. Same thing happened to me. That resistor burned from nothing... My TX is the same and it is not from HK. Its the same one as showed in the picture. Just measure the hot output to camera and its showing less than 3-4v as yours.
I really understand what you did and I will try that solution too. Very cleaver, I liked.
But one thing must be said. The Voltage Out to power up the camera is not 5v, but same as the input. So if you are using a 3s on power supply the TX that video output should be around 12v. There is no 5v out put in this tx. That`s why a 12v camera is needed to use with this TX.
About the burned component. I have no clue why it fried. I was using it normally for over 20minutes when the roll over image showed up. And then I saw the cover burned and that component toasted...
I just had the same problem, I wonder if anybody has found the the resistor number of if is possible to fix it.
It will be difficult to guess unless some one with similar model looks ( without toasted resistor) looks at it with mag lens or measures it and tells us. Mine is cased and sealed and definitely not the same :(
go to the HAM members page and ask them .... they are on the HAM page
I have the same thing on my HK 5.8 400mW Tx. Mine occured when I briefly connected two pins with a multimeter probe. My video still works however I get the rolling pattern overlaying the video. I am not convinced this is a resistor as I noted there were two other identical looking smds on the board (also adjacent to the SS14 chip) that did not register a resistance when measured. I suspect they are capacitors but do not have a suitable meter to test. It would be very generous of someone with the same transmitter to measure the chip so that we could replace it!
In the mean time my tx is still usable...
sorry for my bad englishi'm french
i repared it with a friends,
the composant is just a "fusible", not a resistor or condensator
so we just add a piece of electric cable and now it work !!!! :o)
i'm very happy
