I had a G07 with good brightness but tearing and general quality issues.
I did the cap kit including R908.
After putting it all back together, the screen comes on and the game is visible, but is VERY dim.
I checked B+ and it reads about 96VDC. Adjusting the B+ pot seems to make no difference.
I pulled the chassis and went back to the bench. I checked/reflowed all of the solder joints, and verified that the new R908 was 47K. In some areas, I checked for trace continuity from new parts to neighboring pads (to eliminate cracked or raised traces).
I checked the B+ pot and it appears to vary in resistance from 0-2.2K.
I pulled X901 and X902 and used the transistor test on my DMM. Both were "in spec".
Should I replace them any way?
Why the loss of B+ adjustment after a cap kit?
Any other recommendations?
Thanks...
