Last weekend, I changed the batteries in my T2 and have had power issues ever since. Double checked the batteries, ribbon cable connections, etc and checked all of the fuses with my multimeter (replacing two). The game makes a humming sound when you power it on, but does not light up or make the normal sound when it is running the diagnostics at startup. I have checked everything I can think of and am currently thinking that the led light (d19) on the CPU board always being lit (versus turning off at normal operation) might be a clue. Not sure what to do next or what the issue might be though. Please help. I am stuck and would really appreciate any advice. Thank you

Just removed the batteries, then turned on the game, but no change.

Just tried the service outlet and there is power. I need to read up again on how to test for voltage though to say whether the 5v/12v works for sure though. I will do this tomorrow and post what I find out. Thank you for responding

Ok I checked the voltage coming into the CPU board at j210 and it reads correctly 5v and 12v. Not sure what else to try. Did try to check the bridge rectifier but am not sure I if have to remove it from the board (with a special tool I think) to test it (the pinside diagram shows one that looks different than mine). So confused.

I have never tried this (ever) but can figure it out and give it a try if you think it is the logical next step. Not even sure at this point which are the socketed chips. Is there anything else you would try first?

Also, I just unplugged the clip on j210 and some of the GI lights and some other lights came on, the gun moved back and forth a few times (display still was almost all of the way out), then it stopped and the lights all went out again. I am thinking j210 might be the issue but not sure how or what to do

Ok every time I unplug j210, it blows fuses f111 and f112. Please let me know if anyone has any advice. Thanks

I don't know if it's checking but do know it makes the initial sound that you hear when you turn it on. Maybe it's not called a clip but when I unplug what is plugged into j210 all hell breaks loose

Nope

I would really appreciate any additional advice that might be out there.
