Hi guys! Need your opinion about changing RX board. Repair started from not working caliper function fixation (not solve now). After more deep testing we reveal failure RX board in absolute results and relative to median results for all harmonics (1, 3, 5); other boards passed tests successfully. According service manual review not working RX board (beamformer) results in broken video image quality but pictures is quite normal for quite old system! How much will it useful to replace RX board?
