klv 32ex300 panel issue solve
A Sony KLV-32EX300 model arrived for repair due to a display issue. Upon inspection, I discovered a fault in the panel, specifically in the scalar strip. The DC to DC IC was functioning correctly, and all voltages and LVDS signals were normal. However, I identified that the scalar strip R56 (2.2 ohm) and the BT4 conductor coil were faulty. After replacing these two components, the panel displayed correctly, and the repair was completed.
