SonyBE2A KVM2140picture faded over several hours & the sound level reduced too.When changing the volume, also adjust brightness.usually caused by Q005 (2SA1162-G or 2SA 1037K). This device reads high resistance when tested & needs checking on the ohms time 100 scale of the AVO. In my set this SM transistor was OK. The fault at length was traced to C012 22mfd 50v which was leaking through the PC & had damaged SM resistor R045 47K along with a piece of print running it. All SM parts in this area had to be removed & the PCB cleaned up & bridged where the acid had damaged the print.14-09-04
