For the isolator L900, would it just be a visual inspection? Or is there something specific I need to check for, like continuity?
Same for the t900 transformer?

Contrast nob definitely works. Can adjust with no issues... other than no picture =P
If it is a chip issue, is it repairable? Or is this now a paperweight?

Oh, it definitely receives power. The LCD lights up.. but black.
I've tried powering from an official North American AC adapter (with step-down transformer) as well as fresh batteries. Same results either way.
Audio: Sometimes when it turns on, there's an audio buzzing from the speaker, but usually it's just a faint hum that I hear in a Turbo Express that was recapped.
Video: Sometimes the LCD powers up black and sometimes it powers up with a purple image. I'm testing with HuCards that work in other PC Engine consoles.

Thank you for the responses, and sorry for the delay!
I did clean it up with 99% isopropyl after I removed all the caps initially as there was quite a bit of leakage at that time.
The work was done by a place here in Japan called BEEP. Specializes in old game consoles, arcade boards, etc.
Here are pics that BEEP sent me back after caps were installed but still no sound or video.

If needed, I can open it up again and take more shots.

Console Repair/Mod Center / PC Engine GT - no video or sound before and after cap replacement

I first received the GT back around 2005 a friend. It powered on fine, but the audio was suuuuper quiet. I put it back in a closet and forgot about it. Fast forward to 2016 and I've started to do some soldering.
I replaced the caps on a PCE Duo without much issue, so I thought I'd be able to do that on the GT.
I turned on the GT to test, and there was no video or sound. The screen would power up, but a black image.
I opened it up, removed all the caps... and then didn't realize how tight of a space there was to work in. I knew I wouldn't be able to install all the new ones myself, so I sent it off to someone to have them install the caps.
I got an e-mail saying caps were installed, but there was still no video or sound. It was mailed back to me.
Any suggestions what it could be? Is this fixable or do I just have a decoration piece?
