I decided to try getting this hulk of a beast running. The only problem? I seem to have a problem with the backlights, and I spent all day modifying the connections to accept a more-standardized system (Du-Pont)
I'm trying to use the compatible screen I found with my T-6400DXC back in 2017 (I still hate that computer. Really bad ergonomic design, aesthetic, and size.), but I'm unable to get a stable light.
I've posted a few times about modifying the internals of the lid casing to accept it, but I was hesitant to because I wanted to keep it as stock as possible.
Imagine my luck when I found that a hinge support post had broken off on the inside, so it wasn't exactly mint-quality anymore.
Now this was a somewhat easy repair, after stumbling over the post's plastic that kept breaking under stress when I tried to cement it together. I used a standoff with the same friction bearing, which is now melded into the post a halfway further down (which I did using a soldering iron), and seems to be stronger, since it's closer to the casing: https://imgur.com/RLSRhwq
But i digress, I snipped off the parts of the casing preventing me from placing the screen in neatly. (with a pair of flush cutters), and got to work modifying the connections of the backlights, so I could hopefully use the inverter with the backlights of the compatible LCD module. I keep getting an oddity: The lights pop on for a second, and then switch off.
Worse? The inverter circuit does the same thing with the original backlight too. Then again, the problem may be because I only have one light plugged in, and it may need a certain load to activate and stabilize. I only have been able to find one inverter light cable to use at the moment.
Anyways, in both cases, they turn on and then switch off. But, I get a better, more consistent light with the original backlights, yet they won't stay lit.
I understand that this is all experimentation, so is there anything that I'm doing wrong? Based on what I think is a logical and not-too-far-off assumption, it seems like the inverter circuit should work with what I have, seeing (from newer to older) that the T-6400DXC was a step-up (yeah, right) from the T-6400SXC, which was closest in specifications to the preceding T-3200SXC:
T-3200SXC: Original LQ10D013 monitor + Inverter (foundation)
T-6400SXC: Same Monitor, Different Inverter design (same power specifications?)
T-6400DXC: Different monitor (LTM10C013), but probably same 6400SXC inverter design.
