Hi folks! I thought you might want to see my new toy? A PC Engine GT.... Inside and out!
Yes? OK!
Here goes!
I'm gonna take out ALL the Electrolytic Caps and replace them... Why? Because the GT is notorious for failing Audio and Video because the Caps NEC uses are pure ASS! My particular unit was got "cheap" because it has (had) audio issues.
Here's a great guide to replacing your caps over on pcenginefx: -

Lets get this beast open!
Yum yum!
Board is out, this thing is tiny! Amazing it was made in 1990!!
Getting started with the caps, the small one is the single cause of the dreadded "blank white screen" video issue that many of these units have, replace that and... DING! Video back (great folks over at www.pcenginefx.com need credit for that also, its an all round awesome site for all PC Engine malarkey). Its wise to do all of them though, some are hiding under that metal shield so that has to come off too.
Here is the board with plate off and all the caps replaced! It took me about 2 hours of careful work to get them done.
Don't forget the one on the controller board!
Here's the LCD screen! What a bulky old boy! Be very careful with this beast, you only need to look at it and 10 pixels die instantly! Once i'd put it back together I discovered one of the pixels had gotten stuck, I was ULTRA careful with it too. I have a proggie (again, very cool people at pcenginefx) I can put on a Neo Flash 128 cart one day when I Can afford one that should hopefully unstick the pixel. When playing its barely noticeable anyway.
Arty shot!
All back together again
Here it is running with Don Doko Don! (awesome little game). Video is even nicer now as well as nice loud clear audio! WIN!
I've ordered a switchless mod chip over on pcenginefx (a dude named blueBMW has them here: - http://www.pcenginefx.com/forums/index.php?PHPSESSID=9c7383f14229839e7134a738517065a3&topic=10112.0 ) This will enable play of US games by simply holding SELECT button on power up! Will show more when it arrives
Cheers!
