Hey everyone,
first time poster, long time lurker
I'm having some issues with getting a Gameboy DMG revived that I bought of Ebay. The package contained 2 gameboys, but listed as not working. The first I had was really easy to repair since it only suffered from vertical lines.
The second one however is a complete mysterie to me.
When I insert batteries or connect up a power adapter and turn on the gameboy, the following happens:
* The "pop" in the speakers
* The red led lights up
There's no sound comming from the speakers, nor does anything at all show up on the display. I've used a Multimeter to measure the currents on various points on the board. The board holding the cardridge connects seems to be working fine and has power everywhere I meassured.
The board holding the display however was strange. I could meassure currents on various locations, but on several keypoints there was nothing to be meassured.
I replaced all capacitors already that I could. The only ones left to replace are the 1microF/50V ones on the back of the display, but bit scared of doing that since I need to go under the display with the soldering iron.
Anyone who can give out some pointers of things to check in this gameboy? Or someone who has encountered a similar situation?
