![]() Looking for advice concerning no picture. has back lights and sound. i have vgl -7.89. vgh low at 11.85 and no avvd voltage found, i have few other voltages marked in the pictures. Can anyone tell me which test point is avvd.
All voltages i found are marked in the pictures. No caps were shorted, so maybe someone can point me in the right direction to help narrow the issue down |
