Need Help, Trash?? Anyone??

[jamiekulhanek]

Hey,

My konami digi-q tiger tank is dead.

It will not charge, and even when i attempted to charge it when i disassembled it, the battery took in the charge no problems, but the pcb in the tank is dead.

I am totally SPEWING about this as it cost me $110 for each of my tanks, and these tanks are only fun in pairs…

I’ve checked for any evident damage to the PCB, but no luck.

Can anybody help me out?? Thanks.

P.S. I posted this message in this section as nobody goes in the digi-q section.

sorry, I haven’t had the chance to login lately.

Umm.. got to get my brains out of the jar I’ve been keeping them in the past week…
ummm…. I’m just considering the option of pulling my tank apart to see what is inside.
Do you have a close up photo of the PCB ? that might be the place to start.

email me trash0@hotmail.com just in case I I’m busy over the next few days.

I cant get close ups, cause my canon A75 does horrific macro shots.

To take the PCB out, you have to desolder the charging pads….

ummm…. ok, time to try some silly idea’s.

stand back and try a zoom shot, or have somebody hold a magnefying glass for a shot.

looks like I’m going to have to get mine open.
Got any pointers for me ?

[jamiekulhanek]

Um, don’t lose anything, it’s pretty straight forward, but the PCB is soldered to the charging tabs….

Danger! danger will robinson!

just popped mine open…
ok, I guess we do this logically. The batteries, should charge up and not really be in any part of the circuit to the tank.
If you charge the batteries up independantly, the tank works yes ?

This means, bot the batteries are fine and the tank circuit is basically ok.

When the tank is not ON, it should have the battery switch across the contacts. So lets check that it is actually getting power to the tank.
do you get a voltage on the solder pads on the board from the charging pads, when it is on the charger ?

If yes, then I suspect it is the switch itself is dicky or the PCB, in particular the plated through hole where the triangle and RU symbol is.

Check for the charging voltage at the hole and the switch itself.

That’s got to be a start.
I took a picture, but I can’t seem to find any file attachment here ? doh !

[jamiekulhanek]

The battery voltage is fine, but the charging pads have no voltage on them….

I’ll look more intoit

[trash]

Hmmmm…. sounds like the tank should be ok then ?

[jamiekulhanek]

nope, when the battery is charged, and you switch it on, the LED doesnt flash..

[betty.k]

maybe the switch itself is history?:8ball:

[merc-blue]

could it be the chargin curcuit in the controller?? im sure it wont be to hard to get a new battery if thats wats blown.. if u have a pair try swapping the Id for the other controller and using that?

[jamiekulhanek]

Merc read my god damn posts…..

I have tried swapping ROM chips, and the battery takes charge from an external source directly through the battery wires, but the charging pads show 0v on them…and the tank shows no sign of hoping to operate either…
