so any one willing to help please let me know because i cannot afford new radio :help: :help: :help: :help: really sad :(
What Radio is that. I think you connected wrong polarity. Send some pictures. If their is a fuse I may be able to help you.
Yup, either wrong polarity or wrong voltage.
Anyways, the best is to open it up and investigate; post some clear picture and maybe someone might be able to help
thanx for reply
this is hobby king t6a v2
radio is repared by a radio spealist he told that nothing gone wrong whit that radio every thing is ok but he cannot make out why my radio is not responding
first thing is try charging your battery pack....!
always once you u buy a new pack you should charge and then put it ti use.. even if you are soldering it, charge it before that
did you out back the AA batteries and check..??
the was charged when i connect it to radio & it is not working with aa cells
Check the ON-OFF switch for loose contact.
i did every thing which is possible
this one also
dear it is just an electronics problem , you will surely get helped dont wory .
What TX battery did you try (any online links) ? Did you have to modify the connectors of the new TX battery you tried ?
HobbyKing radio's require all switches to be in down position before turning on .... did u check if those 2 switches on the top are switched down?
Ritz..first of all make sure your battery or battery pack is ok, by measuring with multi meter, and check it with a light load, like a simple motor or a bulb. prior that check your total voltage of the battery pack. i hope it will be 8 cells, if dry cell it will be 12 volts, and if rechargeable it will be in 9.6 volts. make sure the battery voltage is proper. you can check the voltage by opening the back cover, and placing the probes of the meter on to the terminals, in black(negative), and red(positive) seen on back cover. if the battery voltage is ok, check for the power indicator, situated at the front of the radio.if it shows yellow, or red, the voltage will be lesser. if the indicator is not lighted, you must trace the circuit for any open, or short circuit.if the power indicator lights up, try to rebind the TX with RX. you can trace the circuit, from the + point of the battery, up to the MCP, and make sure a 4 .8 volt, or 3.3 volt is reaching to the MCP. if still persists it need a thorough checking again.
i observed spark somewhat here when i connected my battery
from this hole

Got it, it is the 7805 IC which has blowen off...
No lipo problem. While soldering, the two contacts of +ve and -ve must have shorten...
l;ink of my tx battery
actually 78L05
Pl find attached internal photos and schematic diagram :thumbsup:
hy guys plz help me out
Hi Ritz, What is the issue. have you checked by changing the 7805 IC ?
this part is not available
Pl check with radio/ tv repair shop. You will get the same. It hardly cost Rs.5/-
