Question about Philips Magnavox 42MF521D/37 Television
Blue light on no picture no sound remote will not work battery change
With solid blue led set could be still powering on but would need to verify by checking power supply voltages. if up and signal is present with no menu or audio would be ssb as audio amplifier, micro processor and eeprom are on that board. if voltages are not present you need to offload x and y sustain boards one at a time from power supply and check voltages and if vs comes up with either board disconnected replace that board
