pc engine GT issue

[souldav]

hello.

It's my first post so i would like say thank you for this forum and website.

I just bought a pc engine gt unit and it does not power on correctly, i need to let it powered (with psu) for 2 or 3 minuts before the image apear.
then it will work correctly.Is it a known gt problem?

i opened it and a saw a capacitor was replaced CC800 (on the button card) could someone give me the original value of it?

thank you and sorry for bad english.
