Here I am with another Pc Engine duo..
I got the machine around two weeks ago for my collection and it was working fine, then I decided to install the RGB as I had some rgb boards with 7314 on it at home.
Unfortunately something went wrong as I broke 2 solder pads (n.60 and 58) of the board where the HUC6260 is soldered ...
I checked the schematic of the HUC6260 and that legs are labeled as "TEST". However I decided to finish to mod the console and check the results but unfortunately the console doesnt work properly. As I made even the rgb cable I thought that way be the problem, but even by the "old" composite cable the image glitches.
The glitch is not stable.. its more similar to an intereference with kinda of greenish stripes that appears on screen. Sometimes everything seems normal...
I double checked with multimeter everywhere, I tried another 7314, i rewired the rgb cable, tried different games, without game, connected and disconnected the c.sync.... but same result.
I want to reconnect the legs, but I dunno where... I got another pc engine duo from a friend to check where that legs go.. but I cannot find it!!
I am not a novice in soldering and I really feel stupid for what I have done there.. can't forgive me. ?
Hope you can help me guys
Here some picture of the board.
