Hello everyone, long time listener, first time caller... need some help.

My transmitter is a JR X347 which has been a fairly capable (if a bit old) piece of equipment until lately.
First the battery life is signifigantly reduced and won't charge above 8 volts and soon after won't take a charge at all.
No Problem - got a new 2000mah battery.... radio still won't turn on even though there is power in battery.
Ok, so now i changed the lithium battery inside(never again). It still won't work.
Remove the Module at rear and find the fuse... it's blown. Replaced the fuse. Transmitter still Won't turn on.


What's the story now. Can it be fixed. Any ideas on something i may have overlooked.

Or should i just get up, dig deep, and buy a new one?

Thanks in advance for your thoughts.
