TVbGone doesn't work always

by ks3556 on Sat Sep 01, 2012 3:41 pm

Hello everyone, ive got a problem with my TVbGone Kit.

The Problem is, i doesn't work all the time.
When i put new batteries into the holder, it works very good for about 2-3 times, but the following 'rounds' the green led blinks only for 3 seconds or so. :(
When i waited some minutes or pushed the button very long, it worked several times again. :?:
Please dont tell me "aaaww your batteries dont have enough power, use new ones".. i've already tried that :) And the Voltmeter says the batteries are Full.

It doesn't look like there's a short circuit somewhere, so i think it has to do with the IC, maybe?

Please Help Me :D

Have a nice day

What does the battery voltage do when you are transmitting.

I had similar issues when I put in some non alkaline cheap ones, they just sagged too much under load.

If you post photos of the front & back of the board we can check for assembly issues. But from the symptoms you report, as suggested by richms, batteries are the most likely suspect.

so i think it has to do with the IC, maybe?

If it were a defective IC, changing the batteries wouldn't help.
