My Hitachi 29"CTV blew on low voltage mains supply. Power dropped from normal 240Vac to about 80Vac and blew a few components in primary and secondary supply cct.(uses SMPS).
Repaced all blown components ie Q902-BD329, Q901-KTA1266Y, Q903-ON4959, PR901-1A fusable resistor and ZD952-HZS27-2L and when powered the 130vdc rail has double the voltage to 230Vdc and 22.5vdc rail has also doubled to 47vdc.
Can anyone with hints to resolve this probem help me. Has given me a headache for sometime now.
I have the cct diagram though for C2589FS/C2578FS/CMT2578 not too sure whether it's exact to my TV but looks so.
