wow thanks so the board on a GT will be blank there right?
still not working tho. is there a list here of what the cap voltages are supposed to be? I am bound and determined to save these systems.
thanks.

So after continuing investigation into this matter I found something this morning. Apparently there is a resistor that was blown off the board when the caps were being removed. Does anyone know the value of resistor r723? Thanks

K never mind the above post. I took the controller board from the Turbo Express and replaced the cap and installed it and nothing. I also did the same with the PC Gt board that cap was absolute crap. Same thing nothing.
Kinda starting to feel like these guys may be dead.

Sorry to sound like a idiot but what exactly do you mean by controller board? thanks

[Console Repair/Mod Center / Re: PC engine GT help needed]

Nope I was right all other caps are asleep. How do I trace where he power goes once it leaves the fuse?

[Console Repair/Mod Center / Re: PC engine GT help needed]

Hi thanks for the response. Here is where I am at now. I only have .25v at cc101 and .20 at cc102. I have no voltage at any other caps. I now have 9.5v at the fuse and 1.25v at the rear if the ax adapter. Hope someone can help further feels like I am close but.... We will see.

I have around 9v at the plug going into the board. I plugged the ac adapter and still does not power up but the voltage at the fuse comes up to around 2.5v. Hope this helps.

Hello all long time TGrafx owner and fan. I am currently working on a turbo express and a pc engine GT. the questions here are related to the pcgt. I have replaced all the caps with smd caps. I have double and triple checked orientation and all connections appear good. Problem i am having is the console will not power up. I replaced the fuse witch was bad and i now have power at the plug going into the board. But thats all. I back probed the fuse solder points and i have continuity thru the fuse. But i have no measurement of voltage. Any ideas? I have read thru the forums but have not found anything that could help me with this. Thanks in advance

[Console Repair/Mod Center / Re: Turbo Express ?]

I was wondering if the connector was causing a low voltage situation is this possible? and where should I solder to the board, thanks

[Console Repair/Mod Center / Turbo Express ?]

Hello all I have a ? that would be best suited to the experts here. I have a Turbo Express I picked up with no vid and faint sound. I started replacing some caps and found a no-no. The red and blue wires that come off the batteries go to a 2 pin connector on the PCB board. The connector was corroded and I am wondering if this was/is causing a problem. Attached is a pic I am worried about the connection on the left any ideas on how to fix this? any help would be appreciated thanks
