I'd like one please...USA

?

I'm hoping to test them tonight, can TP18 be grounded to turn the system on. How can you tell this my looking at the schematic? By that I mean, what part of the schematic tells this, I want to learn, so is like to see this for myself too

What's the best way to trigger the system on without the flex cables hooked up? I assume I can ground a certain point or jumper a certain point?

?

Can I still test for power with the ribbon cables unplugged and the board out? I thought if they weren't plugged in properly the system wouldn't power on?

I'll measure c41 tonight and as for swapping LCD's everything worked perfect at the time. Upon reassembly they were both dead, but with constant reassembly I did get the older one to work but it went off again. I'm starting to wonder if it's bit the black ribbon cable, the black terminals seem scratched off. I'm thinking of trimming the cable

I should add that I noticed a lot of blue corrosion on the legs of one of the larger capacitors, so I did recap the newer one as well thinking maybe that's my problem, but it's still unresponsive and also I am testing all of this with a game in the slot.

I recapped a free Lynx 2 about 2 years ago and it would power on, but the screen had odd graphics patterns so I gave up on it thinking it was an LCD issue. Recently I picked up a functioning Lynx 2 with 40 games and decided to swap parts between the two to see if I could find the problem with the old one. I used the newer systems main board and it worked prefect, so I knew it was something with the older ones main board. Upon reassembly neither of them work now, they are both dead, no back light, no power light. Im using an official Atari power adapter which I've checked with my meter and it's working properly. I've also tried 6 NEW batteries and get the same thing. I found the mosfet bypass trick and ran a wire from battery negative terminal to headphone negative and still get nothing on either with power adapter or batteries. During all of this swapping I did get they older one to randomly turn on, but it stopped working again. I also checked the 3 pins on the board where the adapter is plugged into and get 13 volts at these terminals. Please help me figure out what terminals to test with my meter and what voltages to expect. And if I do or don't have power there, what the problem might be.

Correct, it doesn't do anything. And yes I'm talking about the voltage regulator. The middle pin is ground and it ohms out just fine. The left leg should have 13v and the right should have 5v, but neither leg had any power, yet power is getting through the dc port and through the power switch.

I've got power from the power port to and through the switch, but neither of the regulator outer pins have power. I'm not sure where to go from here. Help?
